Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an earphone assembly and a sound acquisition method. Background Technology

[0002] A stethoscope is an essential non-invasive examination device in clinical practice, which can be used to quickly screen for murmurs caused by lesions in organs such as the heart, lungs, intestines, or arteries.

[0003] Electronic stethoscopes have advantages such as high sensitivity to certain signals, portability, and the ability to store and play back stethoscope sounds. However, electronic stethoscopes require wired headphones in stethoscope mode, have low overall structural integration, and limited functionality, resulting in low user willingness to carry them and thus limiting the promotion of electronic stethoscope products. Summary of the Invention

[0004] This application provides an earphone assembly that not only performs basic functions such as audio playback, acquisition, and transmission, but also collects the user's stethoscope sounds by placing the earphones in a storage case, thus serving as a real-time stethoscope device and improving the user's stethoscope experience. This application also provides a sound acquisition method using the aforementioned earphone assembly.

[0005] In a first aspect, this application provides an earphone assembly, including a storage case and a first earphone. The storage case includes a case body, a stethoscope, and a conduit. The case body has a first earphone slot, the stethoscope is fixed to the case body, the stethoscope has a stethoscope cavity, and the conduit connects the stethoscope cavity and the first earphone slot. The first earphone has a first microphone, which, when the first earphone is placed in the first earphone slot, is used to collect auscultation sounds through the first earphone slot and the stethoscope cavity.

[0006] In this application, the sound signal collected by the storage box through the stethoscope cavity can be transmitted to the first earphone slot via a conduit. When the first earphone is placed in the first earphone slot, the first microphone can collect sound signals through the first earphone slot and the stethoscope cavity. When using the earphone assembly for auscultation, the user can hold the earphone assembly and place the stethoscope against the body part to be auscultated. After the auscultation sound is collected by the stethoscope cavity, it is transmitted to the first earphone slot through the conduit. The first microphone collects and stores the auscultation sound transmitted to the first earphone slot, thereby realizing the auscultation function of the earphone assembly.

[0007] The catheter can be airtight, and the connection between the catheter and the stethoscope cavity and the first earphone slot can be a sealed connection to ensure the airtightness of the sound signal transmission channel, so that the noise of the sound signal entering the first earphone slot is small and the signal-to-noise ratio of the auscultation sound is high.

[0008] In some possible implementations, the end of the stethoscope cavity closest to the body of the box has a first cross-sectional area, and the end of the stethoscope cavity furthest from the body of the box has a second cross-sectional area, the second cross-sectional area being larger than the first cross-sectional area.

[0009] In this implementation, the stethoscope restricts the space for sound signal propagation through the structural design of the stethoscope cavity. By gradually reducing the space, the sound intensity of the sound signal is amplified, thereby improving the stethoscope cavity's ability to collect and amplify sound signals, such as improving the ability to collect weak sound signals.

[0010] The walls of the stethoscope cavity can be smooth to reduce sound wave reflection and loss. For example, the stethoscope cavity can be conical or bowl-shaped, and its walls can be flat or curved.

[0011] In some possible implementations, the stethoscope includes a base and a diaphragm, with the base fixed to the housing and having a stethoscope cavity, and the diaphragm mounted on the base and covering the stethoscope cavity.

[0012] The base may have continuous slots around its periphery, surrounding the stethoscope cavity. The diaphragm possesses a degree of flexibility and elasticity, allowing it to deform under external force. When the diaphragm is installed onto the base, its periphery can engage with the slots in the base. At this point, the diaphragm's vibration direction is limited by its connection structure with the base, and the vibration direction is approximately parallel to the thickness direction of the storage box.

[0013] In some possible implementations, the base includes a fixed part and a movable part. The fixed part is fixed to the housing body, and the stethoscope cavity outlet is located in the fixed part. The movable part is arranged around the fixed part and movably connected to the fixed part, and the diaphragm is mounted on the movable part. The movable part can move relative to the fixed part away from the housing body to a first position, and the movable part and the fixed part together form the stethoscope cavity. The movable part can also move relative to the fixed part towards the housing body to a second position.

[0014] In this implementation, the structure of the base enables the stethoscope to be retractable. When the user does not need to use the auscultation function of the headphone assembly, the movable part can be moved to the second position, reducing the thickness of the stethoscope and the overall volume of the headphone assembly, making the product more compact and increasing the portability of the headphone assembly. When the user needs to use the auscultation function of the headphone assembly, the movable part can be moved to the first position, restoring the thickness of the stethoscope to a state suitable for auscultation. At this time, the stethoscope cavity has sufficient height to reduce the reflection of sound inside the cavity, and the stethoscope cavity has a sufficiently large pickup area to ensure the amplification effect of the stethoscope. Furthermore, when the user performs auscultation, the stethoscope protrudes sufficiently from the housing to ensure good contact between the stethoscope and the surface being tested, which helps to ensure the quality of the auscultation sounds collected by the headphone assembly.

[0015] In some possible implementations, the active part is embedded in the housing when it moves to the second position. In this case, the thickness of the stethoscope component is reduced even more significantly, resulting in a smaller overall volume of the headphone assembly.

[0016] When the movable part moves to the second position, the fixed part supports the diaphragm. At this time, the fixed part and the movable part can jointly support the diaphragm, reducing the risk of damage to the diaphragm caused by external stress.

[0017] In some possible implementations, the catheter includes a first conductive segment, a connecting segment, and a second conductive segment connected in sequence; the first conductive segment connects to the stethoscope cavity, and the second conductive segment connects to the first earphone slot; the connecting segment includes an annular segment surrounding the first conductive segment, or the connecting segment includes a serpentine segment.

[0018] In some possible implementations, the tube length ranges from 5.7cm to 34cm, allowing the air resonant frequency within the tube to be in the range of 250Hz to 1500Hz. This enables the headphone assembly to better capture the user's heart and lung sounds, where most of the energy of heart sounds is concentrated between 0Hz and 500Hz, and lung sounds between 0Hz and 1000Hz. The 1000Hz to 2000Hz frequency range is typically the frequency range for abnormal heart and lung sounds. In other implementations, the air resonant frequency within the tube can also be in the range of 0Hz to 2000Hz, thus enhancing the auscultation sounds captured by the stethoscope headphones in the 0Hz to 2000Hz frequency band.

[0019] In some possible implementations, the storage box also includes a sound-absorbing component that covers part or all of the conduit, and the sound-absorbing component is made of sound-absorbing material.

[0020] In this implementation, the sound-absorbing component can isolate external noise, thereby further reducing the noise of the sound signals entering the first and second earphone slots. The sound-absorbing material can be selected from PU foam (polyurethane foam, where PU stands for polyurethane), PE foam (polyethylene foam, where PE stands for polyethene), EVA plastic (ethylene-vinyl acetate copolymer, where EVA stands for ethylene vinyl acetate copolymer), and silicone, etc.

[0021] In some possible implementations, the housing also includes a first sealing ring, which is fixed to the wall of the first earphone slot. When the first earphone is placed in the first earphone slot, the first sealing ring seals and connects the first earphone. The wall of the first earphone slot, the first sealing ring, and the first earphone together form a first acquisition cavity. A conduit connects to the first acquisition cavity, and a first microphone is used to acquire sound from the first acquisition cavity.

[0022] In this implementation, the first sealing ring ensures good airtightness of the first acquisition cavity, which reduces the loss of auscultation sounds from the gap between the first earphone and the wall of the first earphone slot. It also reduces external noise entering the first acquisition cavity from the gap, resulting in higher sound intensity and signal-to-noise ratio of the auscultation sounds acquired by the earphone assembly through the first microphone, thereby improving auscultation sensitivity.

[0023] In some possible implementations, the first earphone also includes a processor and a memory, the processor being electrically connected to the first microphone and the memory, the processor being used to store the audio signal generated by the first microphone into the memory.

[0024] In some possible implementations, the first earphone also includes a third microphone, which is spaced apart from the first microphone and electrically connected to a processor. The processor is used to reduce noise in the audio signal generated by the first microphone based on the audio signal generated by the third microphone.

[0025] In some possible implementations, the first earpiece includes a first antenna, and the earpiece assembly also includes a second earpiece, which includes a second antenna. When the first earpiece is placed in the first earpiece slot and the second earpiece is located outside the storage box, the first antenna and the second antenna are communicatively connected, and the first earpiece can transmit and play the stethoscope sounds collected by the first microphone to the second earpiece.

[0026] In some possible implementations, the storage box also includes a second earphone slot, which is spaced apart from the first earphone slot, and the conduit also connects to the second earphone slot; the earphone assembly also includes a second earphone, which has a second microphone, and when the second earphone is placed in the second earphone slot, the second microphone is used to collect auscultation sounds through the second earphone slot and the stethoscope cavity.

[0027] In some possible implementations, the conduit includes a first sound outlet port and a second sound outlet port, the first sound outlet port being connected to a first headphone slot and the second sound outlet port being connected to a second headphone slot; the conduit also includes a first valve disposed at the first sound outlet port, the first valve being closed when the first headphone is not placed in the first headphone slot and open when the first headphone is placed in the first headphone slot; the conduit also includes a second valve disposed at the second sound outlet port, the second valve being closed when the second headphone is not placed in the second headphone slot and open when the second headphone is placed in the second headphone slot.

[0028] In this implementation, the conduit has four states—a first state and a fourth state—based on the position and number of earphones placed in the earphone slots. This allows the earphone assembly to adaptively connect the stethoscope cavity to the earphone slot where stethoscope sounds are to be collected, and disconnect the stethoscope cavity from the other earphone slot when no stethoscope sounds are needed. This ensures strong airtightness of the conduit, reducing the attenuation of sound intensity during stethoscope sound transmission and improving auscultation sensitivity. Furthermore, since the rotation of the first and second valves is synchronized with the insertion of the first and second earphones into the earphone slots, no manual operation by the user is required, saving unnecessary steps and enhancing the convenience of the user experience.

[0029] When the earphone assembly is in use with only one stethoscope earphone collecting stethoscope sounds, the first or second valve effectively reduces the risk of stethoscope sounds leaking from the earphone slot without an earphone, thus ensuring effective stethoscope sound collection. When using the earphone assembly's stethoscope function, the user can freely select one earphone from the storage box to listen to stethoscope sounds; the other earphone in the storage box automatically becomes the earphone for collecting stethoscope sounds, enabling real-time auscultation. Users do not need to set the currently used earphone or select a specific earphone, making the earphone assembly highly flexible and providing a good user experience.

[0030] When the headphone assembly is in use for collecting auscultation sounds with dual stethoscopes, it can achieve an effect similar to a medical dual-tube stethoscope, reducing potential air turbulence at the end of the tubes, improving the fidelity of the auscultation sounds, and resulting in better auscultation effects.

[0031] In some possible implementations, the first valve includes a rotating part, a closing part, and a triggering part. The rotating part is rotatably connected to the first sound outlet port, the closing part is fixed to the rotating part and located inside the first sound outlet port, and the triggering part is fixed to the rotating part and located in the first headphone slot. When the first headphone is not placed in the first headphone slot, the closing part closes the first sound outlet port. When the first headphone is placed in the first headphone slot, the first headphone pushes the triggering part, and the closing part opens the first sound outlet port.

[0032] In some possible implementations, the rotating part is rotatably connected to the top of the first sound outlet port. When the first earphone is not placed in the first earphone slot, the end torque of the sealing part is greater than the end torque of the triggering part, and the end of the sealing part abuts against the bottom of the first sound outlet port.

[0033] The end torque of the closure part can be generated by the gravity of the closure part, and the end torque of the trigger part can be generated by the gravity of the trigger part. For example, the closure part and the trigger part can be made of the same material, and the volume of the closure part is larger than the volume of the trigger part.

[0034] In some possible implementations, the rotating part is rotatably connected to the top of the first sound outlet port, the end of the closed part is provided with a first magnetic suction member, and the bottom of the first sound outlet port is provided with a second magnetic suction member. When the first earphone is not placed in the first earphone slot, the first magnetic suction member and the second magnetic suction member are magnetically connected.

[0035] In this implementation, since the magnetic connection does not have special requirements for the product's orientation and the magnetic connection relationship is relatively stable, users can place the earphone assembly in any orientation when using it for auscultation without having to keep the lid facing upwards. The first valve can also maintain a stable closed state, thus improving the user experience when using the earphone assembly for auscultation.

[0036] In some possible implementations, the first earpiece has a first antenna and the second earpiece has a second antenna. When one of the first earpiece and the second earpiece is placed in the storage box and the other is outside the storage box, the first antenna and the second antenna are communicatively connected to transmit stethoscope sounds.

[0037] In this application, the earphone assembly's storage box can obtain the number of earphones in the storage box through an in-situ detection function, and select different communication modes according to the number of earphones and whether the earphones are connected to a terminal, so as to facilitate user use.

[0038] For example, in some use cases, when one of the first and second earphones is placed in the storage case and the other is outside the storage case, and the earphone outside the storage case is being worn, the first antenna communicates with the second antenna to transmit auscultation sounds. For instance, when the first earphone is placed in the storage case and the second earphone is outside the storage case and being worn, the auscultation sounds are transmitted through the stethoscope and conduit to the first microphone of the first earphone. The auscultation sounds are then wirelessly transmitted to the second earphone through the communication connection between the first and second antennas, and played back by the second earphone, allowing the user to use it for auscultation. Alternatively, when the second earphone is placed in the storage case and the first earphone is outside the storage case, and the earphone outside the storage case is being worn, the auscultation sounds are transmitted through the stethoscope and conduit to the second microphone of the second earphone. The auscultation sounds are then wirelessly transmitted to the first earphone through the communication connection between the first and second antennas, and played back by the first earphone, allowing the user to use it for auscultation. In this implementation, the earphone component enables real-time auscultation.

[0039] In other use cases, when one of the first and second earphones is placed in the storage box and the other is outside the storage box, and the earphone outside the storage box is being worn and connected to the terminal, the first antenna communicates with the second antenna to transmit stethoscope sounds, and the earphone outside the storage box communicates bidirectionally with the terminal to transmit commands and stethoscope sounds.

[0040] In other use cases, when the first and second earbuds are placed in the storage case and not connected to the terminal, the stethoscope sounds collected by the first and second earbuds are stored in their respective memory. The stethoscope sounds are collected by the earbuds' microphones, undergo analog-to-digital conversion, audio encoding, and format conversion before being written into the memory. The stethoscope sounds in the memory are sent to the terminal the next time the earbuds connect to the terminal, and then output by the terminal; alternatively, the earbuds can be played directly by the earbuds upon receiving a playback command from the terminal the next time they connect to the terminal.

[0041] In other use cases, when the first and second earphones are placed in the storage box and connected to the terminal, the stethoscope sounds collected by the first and second earphones are sent to the terminal.

[0042] In this implementation, the earphone component employs different communication strategies for various scenarios, including when one or both earphones are in the charging case and whether the earphones are connected to the terminal. Therefore, the earphone component can automatically identify the user's purpose based on the product status and execute the corresponding communication strategy, improving the user experience. Specifically, during stethoscope mode, the earphone component can utilize the existing Bluetooth connection between the two earphones (e.g., the internal pairing channel between the master and slave earphones) and the existing connection status with the terminal to select the data link, eliminating the need for re-pairing and saving time spent switching modes. This allows for faster entry into stethoscope mode and a superior user experience.

[0043] Secondly, this application also provides a sound acquisition method applied to a communication system including a storage box and earphones, wherein the storage box has a sound collection device. The storage box and earphones can be the aforementioned earphone assembly.

[0044] The sound acquisition method includes: the storage box detects a first event; in response to detecting the first event, the storage box determines whether the earphone is in place and whether the storage box is in a closed state; if it is determined that the earphone is in place and the storage box is in a closed state, the storage box sends a first message to the earphone; the earphone receives the first message; in response to receiving the first message, the earphone turns on the microphone and acquires a first sound through the sound collection device.

[0045] In this application, the sound acquisition method can acquire sound through an earphone component. While taking into account the basic functions of audio playback, acquisition and transmission, the earphone component can also acquire the first sound through the earphone placed in the storage box, thus serving as a sound acquisition device, such as a real-time auscultation device, thereby improving the user's auscultation experience.

[0046] In some possible implementations, the storage box includes buttons. The storage box detects a first event, specifically: the storage box detects that a button has been triggered.

The method further includes: the terminal receiving a user's trigger operation; in response to receiving the user's trigger operation, the terminal determining whether to connect headphones; if headphones are connected, the terminal sending a fourth message to the headphones; the headphones receiving the fourth message; in response to receiving the fourth message, the headphones determining whether they are in place and whether the charging case is closed; if the headphones are in place and the charging case is closed, the headphones activating their microphone and collecting a first sound through a sound collection device.

[0052] In some possible implementations, after the terminal determines whether headphones are connected, the method also includes: if headphones are connected, the terminal prompts the user to put the headphones into the storage case; the terminal prompts the user to close the storage case; and the terminal prompts the user to place the storage case at the sound acquisition position.

[0053] In some possible implementations, the headphones include a first earpiece and a second earpiece.

[0054] In some possible implementations, the headphones include a first earpiece, and the communication system also includes a second earpiece located outside the storage case.

[0055] The method further includes: in response to receiving the first information, the first earpiece determines whether it is connected to the second earpiece and whether the second earpiece is being worn; if it is determined that the second earpiece is connected and the second earpiece is being worn, the first earpiece sends the collected first sound to the second earpiece; the second earpiece receives the first sound; in response to receiving the first sound, the second earpiece plays the first sound.

[0056] In some possible implementations, the communication system also includes a terminal. After the earphones collect the first sound, the method further includes: the charging case determining whether it is in an open state and whether the earphones are in place; if the charging case is determined to be in an open state and the earphones are in place, the earphones determining whether to connect to the terminal; if it is determined to connect to the terminal, the earphones send the first sound to the terminal; the terminal receives the first sound; in response to receiving the first sound, the terminal determines whether the user has invoked the first sound; if it is determined that the user has invoked the first sound, the terminal outputs the first sound.

The body 11 may include a first earphone slot 111 and a second earphone slot 112, with the second earphone slot 112 spaced apart from the first earphone slot 111. The first earphone 2 can be detachably placed in the first earphone slot 111, and the second earphone 3 can be detachably placed in the second earphone slot 112, so that the storage box 1 can store the first earphone 2 and the second earphone 3. In this embodiment, the first earphone 2 is the right earphone and the second earphone 3 is the left earphone as an example. In other embodiments, the first earphone 2 may be the left earphone and the second earphone 3 may be the right earphone.

[0105] For example, the first earphone 2 may include a first speaker 21 and a first microphone 22, and the second earphone 3 may include a second speaker 31 and a second microphone 32. The first speaker 21 and the second speaker 31 can be used to convert electrical signals into sound signals to achieve sound generation. The first microphone 22 and the second microphone 32 can be used to collect sound signals and convert them into electrical signals. In the embodiments of this application, the first earphone 2 and the second earphone 3 of the earphone assembly 100 can have the basic functions of existing True Wireless Stereo (TWS) earphones, namely, basic functions such as audio playback, acquisition, and transmission, such as playing audio and making calls. To achieve these functions, the earphone assembly 100 may also include an audio codec chip, a power amplifier, a central processing unit, a Bluetooth chip, etc. The circuit structure of the earphone assembly 100 will be described later.

[0106] When the first earphone 2 is placed in the first earphone slot 111, the first microphone 22 is located in the first earphone slot 111, and the first microphone 22 can collect the sound signal within the first earphone slot 111. When the second earphone 3 is placed in the second earphone slot 112, the second microphone 32 is located in the second earphone slot 112, and the second microphone 32 can collect the sound signal within the second earphone slot 112. It should be noted that... Figure 2 The positions of the speakers and microphones shown are illustrative and are not intended to limit the scope of this application.

[0107] For example, the storage box 1 may include one or more indicator lights 13 and one or more buttons 14. The indicator lights 13 may convey certain information to the user, such as indicating the battery status in the storage box 1; the buttons 14 may be used to perform certain specific functions, such as serving as a Bluetooth pairing button. The storage box 1 of the earphone assembly 100 may have the basic functions of an existing charging box, such as charging and storing the first earphone 2 and the second earphone 3. To realize the charging function, the storage box 1 may also include a battery, a power management chip, etc. The circuit structure of the storage box 1 will be described later.

[0108] The storage box 1 is typically flat and has a thickness direction. The second earphone slot 112 is arranged perpendicular to the thickness direction of the storage box 1. For example, the outer contour of the storage box 1 in its thickness direction can be circular, square, or other shapes. The storage box 1 may have a front side, a rear side, and a peripheral side. The front and rear sides are arranged in the thickness direction of the storage box 1 and are opposite to each other, while the peripheral side is located in front of and surrounds the front and rear sides. The front, rear, and peripheral sides of the body 11 of the storage box 1 are understood similarly. For example, the lid 12 is rotatably connected to the rear side of the body 11, and the indicator lights 13 and / or buttons 14 of the storage box 1 can be arranged on the peripheral side of the body 11.

[0109] Please refer to the following: Figure 1 , Figure 2 and Figure 4 , Figure 4 yes Figure 1 A partial structural diagram of storage box 1 is shown.

[0110] In some embodiments, the storage box 1 further includes a stethoscope 15. The stethoscope 15 is fixed to the box body 11, and the storage box 1 can collect sound signals through the stethoscope 15. The stethoscope 15 may include a base 151 and a diaphragm 152. The base 151 is fixed to the box body 11, for example, it may be fixed to the front side of the box body 11. The base 151 may be fixedly connected to the box body 11 by installation, or it may be integrally formed with the box body 11. The base 151 has a stethoscope cavity 1511, and the diaphragm 152 is installed on the side of the base 151 facing away from the box body 11 and covers the stethoscope cavity 1511. The stethoscope cavity 1511 may be formed by the base 151 and the diaphragm 152 together.

[0111] The connection between the diaphragm 152 and the base 151 can be detachable. For example, the base 151 can have continuous slots around its periphery, surrounding the stethoscope cavity 1511. The diaphragm 152 has a certain degree of flexibility and elasticity, and can deform under external force. When the diaphragm 152 is installed on the base 151, its periphery can be engaged with the slots of the base 151. At this time, the vibration direction of the diaphragm 152 is limited by its connection structure with the base 151, and the vibration direction of the diaphragm 152 is approximately parallel to the thickness direction of the storage box 1.

[0112] In some embodiments, the stethoscope cavity 1511 has a first cross-sectional area at the end near the housing 11, and a second cross-sectional area at the end away from the housing 11, the second cross-sectional area being larger than the first cross-sectional area. That is, the opening area of ​​the stethoscope cavity 1511 at the end near the diaphragm 152 is larger, and the opening area of ​​the stethoscope cavity 1511 at the end near the housing 11 is smaller. In this embodiment, the stethoscope 15, through the structural design of the stethoscope cavity 1511, restricts the space for sound signal propagation. By gradually reducing the space, the sound intensity of the sound signal is amplified, thereby improving the ability of the stethoscope cavity 1511 to collect and amplify sound signals, for example, improving the ability to collect weak sound signals. In other words, the stethoscope cavity 1511 utilizes the inverse square law to amplify the sound intensity of the sound signal.

[0113] The stethoscope cavity 1511 may have a smooth wall surface to reduce sound wave reflection and reduce loss. For example, the stethoscope cavity 1511 may be conical or bowl-shaped, and the wall surface of the stethoscope cavity 1511 may be flat or curved. This application does not strictly limit the specific shape of the stethoscope cavity 1511.

[0114] In some other embodiments, the stethoscope 15 may also include a rubber ring (not shown in the figure), which is fixed to the base 151 and surrounds the stethoscope cavity 1511. The connection between the rubber ring and the base 151 may also be detachable. In this embodiment, the stethoscope 15 may or may not include a diaphragm.

[0115] Please refer to the following: Figures 2 to 4 In some embodiments, the storage box 1 further includes a conduit 16, which connects the stethoscope cavity 1511 with the first earphone slot 111 and the second earphone slot 112. The conduit 16 may include a first conductive section 161, a connecting section 162, and a second conductive section 163 connected in sequence. The first conductive section 161 connects to the stethoscope cavity 1511, the second conductive section 163 connects to the first earphone slot 111 and the second earphone slot 112, and the connecting section 162 connects to the first conductive section 161 and the second conductive section 163.

[0116] In this embodiment, the sound signal collected by the storage box 1 through the stethoscope cavity 1511 can be transmitted to the first earphone slot 111 and the second earphone slot 112 via the conduit 16. When the first earphone 2 is placed in the first earphone slot 111, the first microphone 22 can collect sound signals through the first earphone slot 111 and the stethoscope cavity 1511; when the second earphone 3 is placed in the second earphone slot 112, the second microphone 32 can collect sound signals through the second earphone slot 112 and the stethoscope cavity 1511.

[0117] The catheter 16 can be an airtight structure. The connection between the catheter 16 and the auscultatory cavity 1511, the first earphone slot 111 and the second earphone slot 112 can be a sealed connection to ensure the airtightness of the sound signal transmission channel, so that the noise of the sound signal entering the first earphone slot 111 and the second earphone slot 112 is small and the signal-to-noise ratio of the auscultation sound is high.

[0118] Please refer to the following: Figure 5 and Figure 6 , Figure 5 yes Figure 4 A partial structural diagram of the body 11 of the storage box 1 shown. Figure 6 yes Figure 5 The diagram shows a partial structure of the box body 11 from another angle.

[0119] In some embodiments, the second conductive segment 163 may include a first branch 1631 and a second branch 1632, with the first branch 1631 connecting the connecting segment 162 to the first earphone slot 111, and the second branch 1632 connecting the connecting segment 162 to the second earphone slot 112. For example, the conduit 16 may be a separate pipe or may be formed by surrounding structures.

[0120] For example, the storage box 1 may also include a sound-absorbing component (not shown in the figure), which covers part or all of the conduit 16, and the sound-absorbing component is made of sound-absorbing material. In this embodiment, the sound-absorbing component can isolate external noise to further reduce the noise of the sound signal entering the first earphone slot 111 and the second earphone slot 112. The sound-absorbing material can be selected from PU foam (polyurethane foam, where PU is polyurethane), PE foam (polyethylene foam, where PE is polyethene), EVA plastic (ethylene-vinyl acetate copolymer, where EVA is EthyleneVinyl Acetate Copolymer), and silicone, etc.

[0121] Please refer to the following: Figure 1 , Figure 3 and Figure 7 , Figure 7 yes Figure 1The diagram shows the headphone assembly 100 in some usage scenarios.

[0122] In some embodiments, in a stethoscope mode, both the first earphone 2 and the second earphone 3 are housed in the storage box 1, and both the first earphone 2 and the second earphone 3 serve as stethoscope headphones. When using the headphone assembly 100 for stethoscope treatment, the user can hold the headphone assembly 100 and place the diaphragm 152 of the stethoscope 15 against the body part to be auscultated. After the stethoscope sound is collected by the stethoscope cavity 1511, it is transmitted through the conduit 16 to the first earphone slot 111 and the second earphone slot 112. The first microphone 22 collects and stores the stethoscope sound transmitted to the first earphone slot 111, and the second microphone 32 collects and stores the stethoscope sound transmitted to the second earphone slot 112, thereby realizing the stethoscope function of the headphone assembly 100. The stethoscope sound collected by the stethoscope headphones is a human physiological sound, such as the sound signal produced by the heart, lungs, intestines, or arteries. In some embodiments, the stethoscope sound can also be the physiological sound of other animals, or a faint sound from the external environment, equipment, etc.

[0123] After collecting the auscultation sounds, the first earphone 2 and the second earphone 3 can connect to the terminal 200 to transmit the auscultation sounds to the terminal 200. The terminal 200 then outputs the auscultation sounds and / or the auscultation results determined based on the auscultation sounds. At this time, the terminal 200 can store and play back the auscultation sounds collected by the earphones. The terminal can output the auscultation sounds by playing audio or displaying waveforms.

[0124] The earphone assembly 100 enhances the sound intensity of the sound signal through the stethoscope cavity 1511 structure, which helps to improve the sound intensity of the auscultation sounds collected by the auscultation earphone. The airtight design of the duct 16 structure and the design of the sound-absorbing material covering part or all of the duct 16 help to reduce the risk of sound leakage or increased noise during the transmission of auscultation sounds, thereby improving the quality of the auscultation sounds collected by the earphone assembly 100.

[0125] Please refer to the following: Figure 1 , Figure 3 and Figure 8 , Figure 8 yes Figure 1 The diagram shows the headphone assembly 100 in other usage scenarios.

[0126] In some embodiments, in another auscultation mode, one of the first earphone 2 and the second earphone 3 is housed inside the storage box 1 as a stethoscope earphone, while the other is placed outside the storage box 1 as an external earphone. When using the earphone assembly 100 for auscultation, the user can hold the earphone assembly 100 and place the diaphragm 152 of the stethoscope 15 against the body part to be auscultated. After the auscultation sound is collected by the auscultation cavity 1511, it is transmitted through the conduit 16 to the first earphone slot 111 or the second earphone slot 112, where it is collected and stored by the microphone of the stethoscope earphone to realize the auscultation function of the earphone assembly 100. When the external earphone is connected to the stethoscope earphone and is being worn, the stethoscope earphone can also transmit the auscultation sound to the external earphone, which then plays the auscultation sound, allowing the user to hear the auscultation results. The auscultation sound collected by the stethoscope earphone is a physiological sound, such as the sound signals produced by the heart, lungs, intestines, or arteries. In some embodiments, the auscultation sounds may also be physiological sounds of other animals, or faint sounds from the external environment, equipment, etc.

[0127] If the external earpiece is not being worn, the stethoscope earpiece will not send stethoscope sounds to it. After collecting the stethoscope sounds, the stethoscope earpiece can connect to the terminal to transmit the sounds, and the terminal can output the stethoscope sounds and / or the auscultation results determined based on the sounds. At this time, the terminal can store and play back the stethoscope sounds collected by the stethoscope earpiece. The terminal can output the stethoscope sounds by playing audio or displaying waveforms.

[0128] In this embodiment, the earphone assembly 100 incorporates a stethoscope structure within the storage box 1, enabling the acquisition and storage of auscultation sounds via the microphone of the stethoscope earphone placed within the storage box 1, thus integrating auscultation functionality. The earphone assembly 100 not only offers more diverse functions, but also features a limited-size stethoscope component 15 and a newly added conduit 16 located inside the storage box 1. The auscultation sounds are transmitted wirelessly, eliminating the space occupied by wired earphones or stethoscope tubes associated with traditional acoustic cavity electronic stethoscopes. The overall size of the earphone assembly 100 remains small, enhancing its portability.

[0129] Furthermore, the auscultation function of the headphone assembly 100 can be achieved through the original audio processing capabilities of the auscultation headphones, without the need to configure a separate audio processing device to achieve the auscultation function. This effectively controls the cost of the auscultation headphones, resulting in a lower cost for the headphone assembly 100.

[0130] Please refer to the following: Figure 6 and Figure 9 , Figure 9 yes Figure 5 The diagram shows the structure of catheter 16.

[0131] In some embodiments, the second conductive section 163 of the conduit 16 includes a first sound outlet port 1633 and a second sound outlet port 1634. The first sound outlet port 1633 is located at the end of the first branch 1631 and is connected to the first earphone slot 111. The second sound outlet port 1634 is located at the end of the second branch 1632 and is connected to the second earphone slot 112.

[0132] The conduit 16 also includes a first valve 164 disposed at the first sound outlet 1633 and a second valve 165 disposed at the second sound outlet 1634. The first valve 164 is movable relative to the first sound outlet 1633 and is used to close or open the first sound outlet 1633 to disconnect or connect the conduit 16 to the first headphone slot 111. The second valve 165 is movable relative to the second sound outlet 1634 and is used to close or open the second sound outlet 1634 to disconnect or connect the conduit 16 to the second headphone slot 112.

[0133] Please refer to the following: Figures 9 to 11 , Figure 10 yes Figure 3 The diagram shows the internal structure of storage box 1. Figure 11 yes Figure 10 A partial structural diagram of storage box 1 is shown.

[0134] In some embodiments, a first valve 164 is rotatably connected to a first sound outlet port 1633, and its opening and closing are achieved through relative rotation with respect to the first sound outlet port 1633. The first valve 164 may include a rotating part 1641, a closing part 1642, and a triggering part 1643. The rotating part 1641 is rotatably connected to the first sound outlet port 1633, the closing part 1642 is fixed to the rotating part 1641 and located inside the first sound outlet port 1633, and the triggering part 1643 is fixed to the rotating part 1641 and located in the first earphone slot 111. When the triggering part 1643 is not subjected to external force, the first valve 164 is closed, and the closing part 1642 closes the first sound outlet port 1633. When the triggering part 1643 is pushed by an external force, the triggering part 1643 drives the closing part 1642 to rotate around the rotating part 1641, the first valve 164 opens, and the closing part 1642 opens the first sound outlet port 1633.

[0135] Please refer to the following: Figures 11 to 13 , Figure 12 yes Figure 2 The diagram shows a partial structural arrangement of the first earphone 2 part placed inside the storage box 1. Figure 13 yes Figure 2 The diagram shows a partial structural diagram of the first earphone 2 being fully inserted into the storage box 1.

[0136] like Figure 11As shown, when the first earphone 2 is not placed in the first earphone slot 111, the first valve 164 is closed, and the sealing part 1642 seals the first sound outlet port 1633; as Figure 12 As shown, during the process of inserting the first earphone 2 into the first earphone slot 111, the first earphone 2 gradually pushes the trigger part 1643, and the first valve 164 gradually opens, so that the trigger part 1643 drives the sealing part 1642 to rotate; as Figure 13 As shown, when the first earphone 2 is placed in the first earphone slot 111, the first earphone 2 pushes the trigger part 1643, the first valve 164 opens, and the sealing part 1642 opens the first sound outlet port 1633. In some embodiments, the first valve 164 may also have already completed the opening action when the first earphone 2 is partially placed into the storage box 1.

[0137] For example, the rotating part 1641 can be rotatably connected to the top of the first sound outlet port 1633. When the trigger part 1643 is not subjected to external force, such as when the first earphone 2 is not placed in the first earphone slot 111, the end torque of the sealing part 1642 is greater than the end torque of the trigger part 1643. The end of the sealing part 1642 abuts against the bottom of the first sound outlet port 1633 to close the first sound outlet port 1633. Therefore, when the first earphone 2 is removed from the first earphone slot 111, the sealing part 1642 will automatically close the first sound outlet port 1633, isolating the conduit 16 from the first earphone slot 111.

[0138] When the first earphone 2 is placed in the first earphone slot 111, the first earphone 2 is subjected to gravity, possible magnetic attraction (for example, there may be a certain magnetic attraction between the storage box 1 and the first earphone 2) and / or the user's pushing force, so that the end torque of the trigger part 1643 is greater than the end torque of the sealing part 1642. Through the lever action, the first valve 164 is rotated, and the sealing part 1642 opens the first sound outlet port 1633.

[0139] The end torque of the closing part 1642 can be generated by the gravity of the closing part 1642, and the end torque of the trigger part 1643 can be generated by the gravity of the trigger part 1643. For example, the closing part 1642 and the trigger part 1643 can be made of the same material, and the volume of the closing part 1642 is larger than the volume of the trigger part 1643.

[0140] In some other embodiments, the rotating part 1641 is rotatably connected to the top of the first sound outlet port 1633, the end of the sealing part 1642 may be provided with a first magnetic suction member (not shown in the figure), and the bottom of the first sound outlet port 1633 may be provided with a second magnetic suction member (not shown in the figure). When the first earphone 2 is not placed in the first earphone slot 111, the first magnetic suction member and the second magnetic suction member are magnetically connected. At this time, the first valve 164 is closed, and the sealing part 1642 closes the first sound outlet port 1633. When the first earphone 2 is placed in the first earphone slot 111, the first earphone 2, due to its own gravity, possible magnetic attraction force, and / or the user's pushing force, overcomes the magnetic attraction force between the first magnetic suction member and the second magnetic suction member through leverage, causing the first valve 164 to rotate and the sealing part 1642 to open the first sound outlet port 1633.

[0141] In this embodiment, since the magnetic connection does not have special requirements for the product placement, the magnetic connection relationship is relatively stable. Therefore, when the user uses the earphone assembly 100 for auscultation, the earphone assembly 100 can be placed in any direction without having to keep the cover 12 facing upwards. The first valve 164 can also maintain a stable closed state, thus improving the user experience when using the earphone assembly 100 for auscultation.

[0142] In some embodiments, both the first magnetic attractor and the second magnetic attractor can be magnets. In other embodiments, one of the first magnetic attractor and the second magnetic attractor can be a magnet, and the other can be a ferromagnetic material, which may include metals such as iron, nickel, and cobalt. For example, when the first magnetic attractor is made of a ferromagnetic material, the end of the closure 1642 or the entire closure 1642 can be made of a ferromagnetic material to form the first magnetic attractor, thereby eliminating the need to fix an additional magnet at the end of the closure 1642, reducing the process steps and lowering costs; alternatively, the first magnetic attractor can be embedded into the end of the closure 1642 through an assembly method; or it can be integrally formed with the end of the closure 1642 through processes such as metal insert injection molding.

[0143] In some embodiments, the first valve 164 may be provided with both a first magnetic attractor and a second magnetic attractor when the end torque of the closing part 1642 is greater than the end torque of the triggering part 1643, so as to improve the stability of the closure of the first valve 164.

[0144] For example, the actual shape of the cross-section of the sealing part 1642 can be basically the same as the cross-section of the first sound outlet port 1633, so that when the first valve 164 is in the closed state, it can better cover the first sound outlet port 1633. The periphery of the tube wall of the sealing part 1642 used to connect to the first sound outlet port 1633 can be made of a flexible material such as rubber or have a fixed sealing element to increase the friction between the sealing part 1642 and the tube wall of the first sound outlet port 1633, making the sealing relationship of the first valve 164 to the first sound outlet port 1633 more stable, preventing the first valve 164 from shaking back and forth with the movement of the storage box 1, thus ensuring sealing performance. The sealing element can be made of a flexible material such as rubber. In some other embodiments, a certain gap may be reserved between the periphery of the rigid structure of the sealing part 1642 and the tube wall of the first sound outlet 1633, so that the first valve 164 can rotate relative to the first sound outlet 1633. The gap is small and may have a small amount of sound leakage, but it has little impact on the auscultation sound acquisition process.

[0145] In some embodiments, the second valve 165 may be designed with reference to the first valve 164. When the second earphone 3 is not placed in the second earphone slot 112, the second valve 165 is closed, and the second sound output port 1634 is sealed; as the second earphone 3 is placed into the second earphone slot 112, the second valve 165 gradually opens; when the second earphone 3 is placed in the second earphone slot 112, the second valve 165 opens, and the second sound output port 1634 is open. In some embodiments, the second valve 165 may also have already completed its opening action when the second earphone 3 is partially placed into the storage box 1. Other descriptions of the second valve 165 can be found in the relevant content of the first valve 164, and will not be repeated here.

[0146] Please refer to the following: Figure 9 , Figures 14 to 16 , Figure 14 yes Figure 9 The diagram shows the structure of the catheter 16 in some other usage scenarios. Figure 15 yes Figure 9 The diagram shows the structure of the catheter 16 in some other usage scenarios. Figure 16 yes Figure 9 The diagram shows the structure of the catheter 16 in some other usage states.

[0147] like Figure 9 As shown, when the first earphone 2 is not placed in the first earphone slot 111 and the second earphone 3 is not placed in the second earphone slot 112, both the first valve 164 and the second valve 165 are closed, and the first sound outlet port 1633 and the second sound outlet port 1634 are sealed. At this time, the defined conduit 16 is in the first state; as Figure 14As shown, when the first earphone 2 is placed in the first earphone slot 111 and the second earphone 3 is not placed in the second earphone slot 112, the first valve 164 is open and the second valve 165 is closed, the first sound outlet port 1633 is open and the second sound outlet port 1634 is closed. At this time, the defined conduit 16 is in the second state; as Figure 15 As shown, when the first earphone 2 is not placed in the first earphone slot 111 and the second earphone 3 is placed in the second earphone slot 112, the first valve 164 is closed and the second valve 165 is open. The first sound outlet port 1633 is closed and the second sound outlet port 1634 is open. At this time, the defined conduit 16 is in the third state; as Figure 16 As shown, when the first earphone 2 is placed in the first earphone slot 111 and the second earphone 3 is placed in the second earphone slot 112, both the first valve 164 and the second valve 165 are open, and both the first sound outlet port 1633 and the second sound outlet port 1634 are open. At this time, the defined conduit 16 is in the fourth state.

[0148] In this embodiment, depending on the position and number of earphones placed in the earphone slots, the conduit 16 has a first to a fourth state through the opening and closing states of the first valve 164 and the second valve 165. This allows the earphone assembly 100 to adaptively connect the stethoscope cavity 1511 to the earphone slot where stethoscope sounds are to be collected, and disconnect the stethoscope cavity 1511 from the earphone slot when stethoscope sounds are not needed in the other earphone slot. This ensures strong airtightness of the conduit 16, reducing the attenuation of sound intensity during stethoscope sound transmission and improving auscultation sensitivity. Furthermore, since the rotation of the first valve 164 and the second valve 165 is achieved with the insertion of the first earphone 2 and the second earphone 3 into the earphone slots, no manual operation by the user is required, saving unnecessary operation steps and enhancing the convenience of the user experience.

[0149] When the earphone assembly 100 is in use with a single stethoscope earphone collecting auscultation sounds, the first valve 164 or the second valve 165 can effectively reduce the risk of auscultation sounds leaking from the earphone slot without an earphone, thereby ensuring that the stethoscope earphone effectively collects auscultation sounds. When using the auscultation function of the earphone assembly 100, the user can freely take one earphone from the storage box 1 to listen to the auscultation sounds, while the other earphone in the storage box 1 automatically becomes the earphone for collecting auscultation sounds, enabling real-time auscultation. The user does not need to set the currently used earphone or take a specific earphone; the earphone assembly 100 offers great flexibility in use and a good user experience.

[0150] When the headphone assembly 100 is in use for collecting auscultation sounds with dual stethoscopes, the headphone assembly 100 can achieve an effect similar to a medical dual-tube stethoscope, reducing the air turbulence that may exist at the end of the catheter 16, improving the fidelity of the auscultation sound, and resulting in a better auscultation effect.

[0151] Please refer to it again. Figure 11 and Figure 13 In some embodiments, the housing 11 may also include a first sealing ring 113, which is fixed to the wall of the first earphone slot 111. When the first earphone 2 is placed in the first earphone slot 111, the first sealing ring 113 seals the connection between the first earphone 2 and the wall of the first earphone slot 111, the first sealing ring 113 and the first earphone 2 together form a first acquisition cavity 114. The conduit 16 connects to the first acquisition cavity 114, and the first microphone 22 is used to acquire the sound in the first acquisition cavity 114.

[0152] In this embodiment, the first sealing ring 113 provides good airtightness of the first acquisition cavity 114, which can reduce the loss of auscultation sound from the gap between the first earphone 2 and the groove wall of the first earphone slot 111, and also reduce external noise entering the first acquisition cavity 114 from the gap. This results in higher sound intensity and signal-to-noise ratio of the auscultation sound acquired by the earphone assembly 100 through the first microphone 22, thereby improving auscultation sensitivity.

[0153] Similarly, the housing 11 may also include a second sealing ring (not shown in the figure), which is fixed to the wall of the second earphone slot 112. When the second earphone 3 is placed in the second earphone slot 112, the second sealing ring seals and connects the second earphone 3. The wall of the second earphone slot 112, the second sealing ring and the second earphone 3 together form a second acquisition cavity. The conduit 16 connects to the second acquisition cavity, and the second microphone 32 is used to acquire the sound in the second acquisition cavity.

[0154] In this embodiment, the length of the conduit 16 affects the resonant frequency of air within it. Air produces a higher amplitude response at the resonant frequency. To amplify the response at certain frequencies, the earphone assembly 100 sets the resonant frequency of the conduit 16 to the frequency that needs to be emphasized, thereby improving the auscultation experience. Specifically, because the human cochlea has a unique spiral structure, the low-frequency sound components heard by the human ear can mask the high-frequency sound components at the same sound intensity, a phenomenon known as the "masking effect." By designing the resonant frequency of the conduit, the effect of low-frequency amplification heard in a traditional stethoscope can be simulated, resulting in a superior auditory experience. Furthermore, for subsequent processing of the auscultation audio signal, such as using algorithms to identify abnormal rales in lung sounds, emphasizing the frequency of rales helps improve the accuracy of rale identification.

[0155] In this application, the length of the conduit 16 can be designed according to the desired resonant frequency. For example, the length of the conduit 16 can range from 5.7 cm to 34 cm, so that the resonant frequency of air in the conduit 16 is in the range of 250 Hz to 1500 Hz. In this case, the earphone assembly 100 can better capture the user's heart and lung sounds, where most of the energy of heart sounds is concentrated in the 0 Hz to 500 Hz range, and lung sounds are concentrated in the 0 Hz to 1000 Hz range. The 1000 Hz to 2000 Hz range is typically the frequency range for abnormal heart and lung sounds. In some other embodiments, the resonant frequency of air in the conduit 16 can also be in the 0 Hz to 2000 Hz range, thereby enhancing the auscultation sounds captured by the auscultation headphones in the 0 Hz to 2000 Hz frequency band.

[0156] In some embodiments, such as Figure 5 As shown, the connecting section 162 of the conduit 16 can be set as a straight section to reduce manufacturing difficulty. In this embodiment, since the length of the conduit 16 is usually short, the resonant frequency of the air in the conduit will be higher, exceeding the range of interest for auscultation from 20Hz to 2000Hz. The resonant frequency belongs to the noise frequency band. The headphone assembly 100 can eliminate this amplified noise by adding a low-pass filter in software or circuitry, resulting in a high signal-to-noise ratio for the auscultation sound.

[0157] In other embodiments, such as Figure 17 and Figure 18 , Figure 17 yes Figure 1 The schematic diagram of the storage box 1 of the earphone assembly 100 shown is presented in some other embodiments. Figure 18 yes Figure 17 The diagram shows a partial structural schematic of the storage box 1. The connecting section 162 of the conduit 16 may include an annular section surrounding the first conductive section 161. In this case, by coiling inside the storage box 1, the conduit 16 can achieve a greater length, allowing the resonant frequency of the air within the conduit 16 to be better concentrated in the range of 250Hz to 1500Hz or close to this range. Of course, when the resonant frequency of the air within the conduit 16 exceeds the above range, this amplified noise can also be eliminated by adding a low-pass filter in software or circuitry, thus improving the signal-to-noise ratio of the stethoscope sound.

[0158] In some other embodiments, the connecting segment 162 may also include a serpentine segment to increase its length. In other embodiments, the connecting segment 162 of the conduit 16 may also have other shapes, which are not strictly limited in this application.

[0159] Please refer to the following: Figures 19 to 21 , Figure 19 yes Figure 1 The diagram shown is a structural schematic of the storage box 1 in some other embodiments. Figure 20 yes Figure 19 A partial internal structure diagram of storage box 1 is shown. Figure 21 yes Figure 20 The diagram shows the structure of storage box 1 in another usage state.

[0160] In some embodiments, the base 151 of the stethoscope 15 may include a fixed portion 1512 and a movable portion 1513. The fixed portion 1512 is fixed to the housing 11, the outlet of the stethoscope cavity 1511 is located at the fixed portion 1512, the movable portion 1513 is arranged around the fixed portion 1512 and movably connected to the fixed portion 1512, and the diaphragm 152 may be mounted on the movable portion 1513; for example... Figure 20 As shown, the movable part 1513 can move relative to the fixed part 1512 away from the housing 11 to a first position. When the movable part 1513 is in the first position, the movable part 1513 and the fixed part 1512 together form the stethoscope cavity 1511. Figure 21 As shown, the movable part 1513 can also move relative to the fixed part 1512 towards the box body 11 to a second position. When the movable part 1513 is in the second position, the thickness of the stethoscope 15 protruding from the box body 11 is reduced.

[0161] In this embodiment, the structure of the base 151 enables the stethoscope 15 to be retractable. When the user does not need to use the auscultation function of the headphone assembly 100, the movable part 1513 can be moved to the second position, reducing the thickness of the stethoscope 15 and the overall volume of the headphone assembly 100, making the product more compact and increasing the portability of the headphone assembly 100. When the user needs to use the auscultation function of the headphone assembly 100, the movable part 1513 can be moved to the first position, restoring the thickness of the stethoscope 15 to a state suitable for auscultation. At this time, the stethoscope cavity 1511 has sufficient height to reduce the reflection of sound inside the cavity, and the stethoscope cavity 1511 has a sufficiently large pickup area to ensure the amplification effect of the stethoscope. Furthermore, when the user performs auscultation, the stethoscope 15 protrudes sufficiently from the housing 11 to ensure good contact between the stethoscope 15 and the surface being tested, which helps to ensure the quality of the auscultation sounds collected by the headphone assembly 100.

[0162] For example, the fixing part 1512 may not be located in the middle of the auscultation cavity 1511, or the fixing part 1512 may be located in a region away from the middle of the auscultation cavity 1511, in which case the position of the catheter 16 changes with the auscultation cavity 1511.

[0163] In some embodiments, when the movable portion 1513 moves to the second position, the movable portion 1513 can be at least partially embedded in the housing 11. At this time, the thickness of the stethoscope 15 is reduced more significantly, and the overall volume of the headphone assembly 100 is smaller.

[0164] In some embodiments, when the movable part 1513 moves to the second position, the fixed part 1512 can abut against the diaphragm 152. At this time, the fixed part 1512 and the movable part 1513 can jointly support the diaphragm 152, reducing the risk of damage to the diaphragm 152 caused by external stress.

[0165] In some embodiments, a limiter 115 may be provided inside the housing 11. When the movable part 1513 moves to the second position, the movable part 1513 abuts against the limiter 115, which limits the travel distance of the movable part 1513. A limiting engagement structure 153 may be provided between the movable part 1513 and the fixed part 1512 to limit the direction of movement of the movable part 1513 relative to the fixed part 1512. A limiting engagement structure 153 may also be provided between the movable part 1513 and the housing 11 to limit the directional deviation of the movable part 1513 relative to the housing 11. In other embodiments, the earphone assembly 100 may not have the limiter 115 and the limiting engagement structure 153.

[0166] For example, the stethoscope cavity 1511 has a first height at the movable part 1513, and the travel of the movable part 1513 is less than or equal to the first height, so as to avoid the fixed part 1512 puncturing the diaphragm 152 when the movable part 1513 moves to the second position, thereby reducing the probability of damage to the diaphragm 152.

[0167] For example, the limiting engagement structure 153 between the movable portion 1513 and the limiting portion may include a limiting groove 1531 and a limiting protrusion 1532 that engages with the limiting groove 1531. One of the limiting groove 1531 and the limiting protrusion 1532 is located in the movable portion 1513, and the other is located in the fixed portion 1512. This application does not limit this. The limiting engagement structure 153 between the movable portion 1513 and the box body 11 can be set with reference to the above-described limiting engagement structure 153, and will not be described again here.

[0168] It is understood that the movable part 1513 can also move between the first position and the second position in other ways. For example, the movable part 1513 can be threadedly connected to the fixed part 1512 and / or the housing 11, and the movable part 1513 can move between the first position and the second position in a rotating manner. In this case, the headphone assembly 100 may not have a limiting slide 1531.

[0169] It is understood that the movement of the movable part 1513 can be manually operated by the user, or an additional structure can be provided in the headphone assembly 100; this application does not impose strict limitations on this. For example, the storage box 1 is provided with a locking mechanism and a spring mechanism. The locking mechanism can fix the movable part 1513 in the second position in the locked state, and the spring mechanism can pop the movable part 1513 out when the locking mechanism is in the unlocked state, so that the movable part 1513 moves to the first position.

[0170] Please see Figure 22 , Figure 22 yes Figure 3 A partial exploded view of the storage box 1 shown.

[0171] In some embodiments, the body 11 of the storage box 1 includes a main body 116 and a outer shell 117. Some components of the storage box 1 can be fixed to the main body 116, and both the main body 116 and the outer shell 117 are housed within the outer shell 117. The outer shell 117 is fixedly connected to the main body 116. The outer shell 117 may be provided with a button hole 1171. The lid 12 of the storage box 1 includes a lid body 121 and a lid shell 122. Some components of the storage box 1 can be fixed to the lid body 121, and both the lid body 121 and the outer shell 122 are housed within the lid shell 122. The lid shell 122 is fixedly connected to the lid body 121. The lid body 121 can be rotatably connected to the main body 116, so that the lid 12 is rotatably connected to the body 11.

[0172] In some embodiments, the storage box 1 may also include a magnetic suction component 17, a Hall sensor 18, a first circuit board 19, a second circuit board 110, a flexible flat cable connector 120, a USB (Universal Serial Bus) interface 130, a USB circuit board 140, and a button 14, etc.

[0173] For example, the magnetic assembly 17 may include one or more magnets 171, which may be respectively disposed on the box body 11 and the box lid 12, and near the closing joint of the box lid 12 and the box body 11. A Hall sensor 18 may be disposed on the box body 11, and near the closing joint of the box lid 12 and the box body 11. When the box lid 12 is opened, at least a portion of the magnets 171 moves away from the Hall sensor 18; when the box lid 12 is closed, at least a portion of the magnets 171 moves closer to the Hall sensor 18; by sensing the magnetic field of the magnets 171, the Hall sensor 18 can detect whether the box lid 12 is in an open or closed state.

[0174] For example, the first circuit board 19 and the second circuit board 110 can be fixed to the main body 116 of the box body by fasteners such as screws, or by other methods such as snap-fit, welding, or bonding. The first circuit board 19 and the second circuit board 110 are provided with multiple components. There can be one or more flexible flat cable connectors 120, which are used to transmit power and / or data to enable electrical connection between other functional components of the storage box 1 and the first circuit board 19 and / or the second circuit board 110, or to enable electrical connection between the first circuit board 19 and the second circuit board 110.

[0175] For example, the USB interface 130 and the USB circuit board 140 are located at the bottom of the storage box 1. The USB interface 130 is connected to the USB circuit board 140, and the USB interface 130 is used for electrical connection with external devices. The USB interface 130 may include a USB Type-A interface, a USB Type-C interface, or a Micro USB interface. The storage box 1 may also be provided with a USB interface protection structure 150 to protect the USB interface 130 and increase its structural strength.

[0176] For example, button 14 can be fixed to the main body 116 of the box, and button 14 can be exposed through the button hole 1171 of the outer shell 117 of the box to receive user pressing operations. Button 14 can be used as a pairing button. Button 14 can also be used as a stethoscope trigger button. When button 14 is reused, different operating modes of the pairing button can be set to identify the user's purpose of entering pairing mode or stethoscope mode.

[0177] In some embodiments, such as Figure 10 As shown, the storage box 1 may also include a battery 160, which can be fixed to the box body 11 and can be located in the first earphone slot 111 and the second earphone slot 112. Figure 10 (Not shown in the image) The rear side. Battery 160 is used to power storage box 1.

[0178] For example, the storage box 1 may also include a wireless charging coil 170, which can be fixed to the box body 11 and located behind the battery 160. In some other embodiments, the storage box 1 may not have a USB interface 130 or a wireless charging coil 170.

[0179] For example, the storage box 1 also includes a first spring 180 and a second spring (not shown in the figure). The first spring 180 is fixed to the box body 11 and protrudes from the first earphone slot 111, and the second spring is fixed to the box body 11 and protrudes from the second earphone slot 112.

[0180] Please refer to the following: Figure 22 and Figure 23 , Figure 23 yes Figure 3 A schematic block diagram of part of the circuit of the storage box 1 shown.

[0181] In some embodiments, the storage box 1 may further include a processor 190, a memory 1100, a power management chip 1200, and other devices, which may be fixed to the first circuit board 19 and / or the second circuit board 110. The processor 190 may include one or more processing units, which may be independent devices or integrated into one or more processors 190. The processor 190 can generate operation control signals according to the instruction opcode and timing signals to control the fetching and execution of instructions. The memory 1100 is electrically connected to the processor 190. The memory 1100 can be used to store computer executable program code, which includes instructions, and can also be used to implement data storage functions. The power management chip 1200 is electrically connected to the processor 190, the USB interface 130, the wireless charging coil 170, and the battery 160. The power management chip 1200 is used to manage the charging and discharging process of the storage box 1.

[0182] The button 14 is electrically connected to the processor 190. The storage box 1 may also include one or more indicator lights 13, which can be fixed to the box body 11 and exposed relative to the box body 11, and the indicator lights 13 are electrically connected to the processor 190. The first spring 180 and the second spring are both electrically connected to the processor 190, and the first spring 180 and the second spring can be used to transmit power or data.

[0183] In other embodiments, the headphone assembly 100 may include more or fewer components, and this application is not limiting in this regard. The various embodiments of the headphone assembly 100 and their technical features described above can be combined with each other without conflict.

[0184] Please see Figure 24 , Figure 24 yes Figure 2 The diagram shows a partial circuit diagram of the first earphone 2.

[0185] In some embodiments, the first earphone 2 includes a processor 24, a memory 25, a battery 26, a power management chip 27, a first contact 28, a wireless communication chip 29, a first antenna 210, a first microphone 22, a third microphone 23, a fifth microphone 220, an audio codec chip 230, a power amplifier 240, a first speaker 21, a wear detection sensor 250, and a touch sensor 260.

[0186] The processor 24 may include one or more processing units, which may be independent devices or integrated into one or more processors 24. The processor 24 can generate operation control signals based on instruction opcodes and timing signals to control instruction fetching and execution. The memory 25 is electrically connected to the processor 24. The memory 25 can be used to store executable program code, including instructions, and can also be used to implement data storage functions.

[0187] The battery 26 is electrically connected to the processor 24 and is used to power the first earphone 2. The first contact 28 is exposed relative to the outer shell of the first earphone 2 and is electrically connected to the power management chip 27 and the processor 24. The first contact 28 is used to transmit power and data. The power management chip 27 is electrically connected to the first contact 28, the battery 26, and the processor 24, and is used to manage the charging and discharging process of the first earphone 2. Figure 13 As shown, when the first earphone 2 is placed into the first earphone slot 111 of the storage box 1, the first contact 28 abuts against and electrically connects to the first spring 180 of the storage box 1. The storage box 1 can charge the first earphone 2 through the first contact 28 and communicate with the first earphone 2.

[0188] The wireless communication chip 29 can be a Bluetooth chip. The wireless communication chip 29 is electrically connected to the processor 24 and the first antenna 210. The wireless communication chip 29 is used to transmit and receive Bluetooth signals through the first antenna 210, enabling the first earphone 2 to connect with the second earphone 3, a terminal, or other devices via Bluetooth, thus achieving communication. In this embodiment, since the first earphone 2 and the second earphone 3 can connect to the terminal, the terminal can display various states of the earphone assembly 100. For example, it can provide pairing reminders, connection reminders, guide users in auscultation operations, and display acquisition results, waveform playback, and remote doctor interpretation on the display interface, thereby improving the usability of the earphone assembly 100.

[0189] The first microphone 22, the third microphone 23, and the fifth microphone 220 are all used to collect sound signals. For example, the first microphone 22 can collect the user's voice when the first earphone 2 is used for a call; the first microphone 22 can also collect auscultation sounds through the first earphone slot 111 and the stethoscope cavity 1511 when the first earphone 2 is placed in the storage case 1. The first microphone 22 can be the earphone's call microphone, and it can be located at the bottom of the first earphone 2 or in other areas of the earphone; this application does not limit this. It is understood that the connection point between the conduit 16 and the first earphone slot 111 depends on the location of the first microphone 22 when the first earphone 2 is placed in the first earphone slot 111. Taking the first microphone 22 being located at the bottom of the earphone as an example, the end of the conduit 16 is connected to the bottom of the first earphone slot 111.

[0190] The first microphone 22 is electrically connected to the processor 24. The first microphone 22 can convert the sound signals it collects into audio signals. The processor 24 is used to store the audio signals generated by the first microphone 22 into the memory 25. The third microphone 23 and the fifth microphone 220 are both spaced apart from the first microphone 22 and are electrically connected to the processor 24. For example, the third microphone 23 and the fifth microphone 220 can be used as noise-canceling microphones. The third microphone 23 and the fifth microphone 220 can convert the sound signals they collect into audio signals. The processor 24 is used to perform noise reduction on the audio signal generated by the first microphone 22 based on the audio signals generated by the third microphone 23 and / or the fifth microphone 220.

[0191] For example, the third microphone 23 can pick up ambient noise within the storage box 1, thereby reducing noise and improving the signal-to-noise ratio of the auscultation sounds collected by the first earphone 2. The fifth microphone 220 can pick up wind noise, friction noise between the surface being auscultated and the stethoscope, thereby reducing noise and further improving the signal-to-noise ratio of the auscultation sounds collected by the first earphone 2. In this embodiment, the first earphone 2, utilizing its multi-microphone design, can collect ambient noise as well as friction noise and abnormal vibrations generated when the operator operates the storage box 1 for auscultation, thereby performing more effective noise reduction on the auscultation sounds, improving the signal-to-noise ratio of weak sound signals, and also enhancing the user experience during the auscultation process.

[0192] The first microphone 22, the third microphone 23, and the fifth microphone 220 can be microphones of the same type but in different locations and with different functions, or microphones using different pickup principles, such as MEMS microphones and bone conduction microphones. For example, the fifth microphone 220 can be a bone conduction microphone. In some other embodiments, the first earphone 2 may not have the third microphone 23 and / or the fifth microphone 220.

[0193] For example, the audio codec chip 230 is electrically connected to the processor 24, the first microphone 22, the third microphone 23, the fifth microphone 220, and the power amplifier 240. The audio codec chip 230 can perform analog-to-digital conversion, converting analog electrical signals into digital signals; it can also further convert digital audio signals (e.g., PCM pulse code modulation) to convert the data into corresponding audio storage formats (e.g., WAV, MP3), which are then stored in the memory 25 by the processor 24. The power amplifier 240 is electrically connected to the first speaker 21, which is used to convert electrical signals into sound signals. Since audio signals are typically digital signals and lack strong driving capabilities, the speaker requires a relatively strong power signal to produce sound. The function of the power amplifier 240 is to amplify the audio signal to drive the speaker to produce sound.

[0194] For example, the wear detection sensor 250 is electrically connected to the processor 24 and may include a capacitive sensor and a light proximity sensor, which can be used to detect the wearing status of the first earphone 2.

[0195] For example, the touch sensor 260 is electrically connected to the processor 24 and can be used to implement touch control of the first earphone 2. For example, a user can answer a phone call or adjust the volume by touching the earphone. In some embodiments, the first earphone 2 may not include the touch sensor 260.

[0196] It should be noted that the functions of each module can be integrated according to actual needs. For example, the wireless communication chip 29 and the processor 24 can be integrated into a Bluetooth processor, and the power amplifier 240 and the audio codec chip 230 can be integrated into an audio codec chip with power amplification function. In other embodiments, the circuit of the headphone assembly 100 may include more or fewer components, and this application does not limit this.

[0197] In some embodiments, the circuit design of the second earphone 3 can be the same as that of the first earphone 2. For example, the second earphone 3 includes a processor, memory, battery, power management chip, second contact, wireless communication chip, second antenna, second microphone, fourth microphone, sixth microphone, audio codec chip, power amplifier, second speaker, wear detection sensor, and touch sensor. Specific details of the circuit design of the second earphone 3 can be found in the relevant description of the first earphone 2, and will not be repeated here.

[0198] In this embodiment, the earphone assembly 100's storage box 1 can obtain the number of earphones in the storage box 1 through the presence detection function, and select different communication modes according to the number of earphones and whether the earphones are connected to the terminal, so as to facilitate user use.

[0199] For example, in some usage scenarios, when one of the first earphone 2 and the second earphone 3 is placed in the storage box 1 and the other is located outside the storage box 1, and the earphone located outside the storage box 1 is in a wearing state, the first antenna 210 is communicatively connected to the second antenna to transmit auscultation sounds. For instance, when the first earphone 2 is placed in the storage box 1 and the second earphone 3 is located outside the storage box 1 and in a wearing state, the auscultation sounds are transmitted through the stethoscope 15 and the conduit 16 to the first microphone 22 of the first earphone 2. The auscultation sounds are then wirelessly transmitted to the second earphone 3 through the communication connection between the first antenna 210 and the second antenna. The auscultation sounds are then played out through the second earphone 3, allowing the user to use the second earphone 3 for auscultation. The second earphone 3 is placed in the storage box 1, and the first earphone 2 is located outside the storage box 1. When the earphone outside the storage box 1 is in the wearing state, the auscultation sound is transmitted through the stethoscope 15 and the conduit 16 to the second microphone 32 of the second earphone 3. The auscultation sound is then wirelessly transmitted to the first earphone 2 through the communication connection between the first antenna 210 and the second antenna. The auscultation sound is played out through the first earphone 2, and the user can use the first earphone 2 to perform auscultation. In this embodiment, the earphone assembly 100 can realize real-time auscultation.

[0200] In other usage scenarios, when one of the first earphone 2 and the second earphone 3 is placed in the storage box 1 and the other is located outside the storage box 1, and the earphone located outside the storage box 1 is in the wearing state and connected to the terminal, the first antenna 210 communicates with the second antenna to transmit stethoscope sounds, and the earphone outside the storage box 1 communicates bidirectionally with the terminal to transmit commands and stethoscope sounds.

[0201] In other use cases, when the first earphone 2 and the second earphone 3 are placed in the storage box 1 and not connected to the terminal, the stethoscope sounds collected by the first earphone 2 and the second earphone 3 are stored in their respective memory. The stethoscope sounds are collected by the earphones' microphones, undergo analog-to-digital conversion, audio encoding, and format conversion before being written into the memory. The stethoscope sounds in the memory are sent to the terminal the next time the earphones connect to the terminal, and then output through the terminal; alternatively, the earphones can be played directly by the earphones upon receiving a playback command from the terminal the next time they connect to the terminal.

[0202] In other usage scenarios, when the first earphone 2 and the second earphone 3 are placed in the storage box 1 and connected to the terminal, the stethoscope sounds collected by the first earphone 2 and the second earphone 3 are sent to the terminal.

[0203] In this embodiment, the earphone assembly 100 employs different communication strategies for various scenarios, including when one or both earphones are in the storage case 1 and when the earphones are connected to the terminal. Therefore, the earphone assembly 100 can automatically identify the user's purpose based on the product status and execute the corresponding communication strategy, improving the user experience. Specifically, during auscultation, the earphone assembly 100 can utilize the existing Bluetooth connection between the two earphones (e.g., the internal pairing channel between the master and slave earphones) and the existing connection status with the terminal to select the data link, eliminating the need for re-pairing and saving time spent switching modes. This allows for faster entry into auscultation mode and a superior user experience.

[0204] Please see Figure 25 , Figure 25 yes Figure 1 A schematic block diagram of a noise reduction process of the headphone assembly 100 shown.

[0205] During the process of a user using the earphone assembly 100 for auscultation, several types of noise may occur, such as environmental noise, noise generated by the user's hands, and frictional noise generated between the surface of the earphone assembly 100 and the surface of the auscultation position when the user operates it. The first earphone 2 and the second earphone 3 may include noise-canceling microphones to reduce the noise of the auscultation sounds. The following description will take the scenario where the first earphone 2 collects the auscultation sounds, the user wears the second earphone 3, and the first earphone 2 is connected to an external terminal as an example to illustrate the noise reduction process.

[0206] In some embodiments, the first microphone 22 of the first earphone 2 collects the stethoscope sound signal S1, the third microphone 23 picks up the sound signal N1, N1 including ambient noise, and the fifth microphone 220 acquires the sound signal N2, N2 including friction noise between the surface being stethoscoped and the earphone assembly 100. The second earphone 3 and the paired external terminal device both have microphones that can collect external ambient noise signals N3 or N4.

[0207] The processor 24 of the first earphone 2 performs noise reduction processing on the stethoscope sound signal S1 based on the sound signal N1 and the sound signal N2 to form a first noise reduction S2. The first earphone 2 transmits the first noise reduction S2 to the second earphone 3 and an external terminal via wireless communication methods such as Bluetooth. The second earphone 3 and the terminal can optionally perform a second noise reduction processing, that is, the processor of the second earphone 3 and the processor of the terminal perform noise reduction calculations on the received first noise reduction S2 and the ambient noise signal N3 or the ambient noise signal N4 to form a second noise reduction S3 or a second noise reduction S4.

[0208] Finally, the processor of the second earphone 3 can perform gain compensation processing on the secondary noise reduction S3 to compensate for the amplitude loss during the noise reduction process. The power amplifier of the second earphone 3 amplifies the power of the secondary noise reduction S3, which is then played through the second speaker 31 to improve the user's auscultation experience. The processor of the terminal can perform gain compensation processing on the secondary noise reduction S4 to compensate for the amplitude loss during the noise reduction process. The power amplifier of the terminal amplifies the power of the secondary noise reduction S4, which is then played through the terminal's speaker to improve the user's auscultation experience. The terminal can also display the waveform of the primary noise reduction S2, auscultation results, etc., on the screen, and can also store the primary noise reduction S2.

[0209] This application embodiment utilizes the microphones built into the first earphone 2 and the second earphone 3 to eliminate various noises during the auscultation process, thereby improving the signal-to-noise ratio of the sound signal.

[0210] In the above scheme, both the first earphone 2 and the second earphone 3 of the earphone assembly 100 can be used to collect auscultation sounds. In some other embodiments, the earphone assembly 100 can also use only one earphone to collect auscultation sounds, for example, the first earphone 2 can be fixed as an earphone placed in the storage box 1 to collect auscultation sounds. In this case, the earphone assembly 100 can still include the second earphone 3; the earphone assembly 100 may not need to be provided with the first valve 164 and the second valve 165; the second conductive section 163 of the conduit 16 may not need to be branched; the first conductive section 161 of the conduit 16 may not be provided in the middle of the auscultatory cavity 1511, but may be provided biased towards the middle of the auscultatory cavity 1511; the box body 11 may not include the second sealing ring.

[0211] For example, when the headphone assembly 100 is fixedly using the first earphone 2 to collect auscultation sounds, the first earphone 2 includes a first antenna 210, and the headphone assembly 100 also includes a second earphone 3, which includes a second antenna. When the first earphone 2 is placed in the first earphone slot 111 and the second earphone 3 is located outside the storage box 1, the first antenna 210 is communicatively connected to the second antenna, and the first earphone 2 can transmit the auscultation sounds collected by the first microphone 22 to the second earphone 3 and play them. At this time, the headphone assembly 100 can realize real-time auscultation.

[0212] It is understandable that when the headphone assembly 100 uses only one earphone to collect auscultation sounds, apart from the aforementioned differences, other features of the headphone assembly 100 can be the same as or appropriately adjusted as the scheme where both earphones can collect auscultation sounds, which will not be elaborated here.

[0213] This application also provides a sound acquisition method applied to a communication system. The communication system includes an earphone assembly, which includes a storage case and earphones. The storage case has a sound collection device. In the sound acquisition method, the earphones, placed in the storage case, acquire sound through the sound collection device of the storage case. The structure of the earphone assembly can be referred to the relevant description in the preceding embodiments. In some embodiments, the communication system may further include a terminal. In this application, the sound acquisition method can acquire a user's auscultation sounds, which can be played through another earphone being worn, or through a terminal connected to the earphones, thereby achieving auscultation.

[0214] In this application, the communication system can assist users in operating the system during the sound acquisition process through headphone prompts, storage box indicator lights, and terminal display interfaces, thereby improving ease of use.

[0215] In this embodiment of the application, the sound acquisition method mainly includes a sound acquisition step and a sound processing step. The sound acquisition step is mainly used to explain how to acquire sound, and the sound processing step is used to explain how to process the acquired sound.

[0216] The following are examples.

[0217] A first embodiment of the sound acquisition steps of a sound acquisition method:

[0218] Please see Figure 26 , Figure 26 This is a flowchart illustrating some steps of the sound acquisition method provided in this application in the first embodiment. Figure 26 The diagram mainly illustrates the sound acquisition steps of the sound acquisition method.

[0219] In the first embodiment, the sound acquisition method may include:

[0220] Step S1101: The storage box detects that the button has been triggered.

[0221] The storage box has a button. When the storage box detects that the button has been triggered, it detects a first event. For example, the triggering action could be the button being pressed two or three times consecutively, with the time interval between two adjacent presses being less than or equal to 1 second, such as less than or equal to 0.8 seconds. Alternatively, the triggering action could be the button being pressed continuously for a certain duration, such as 3 to 5 seconds. The button can be a pairing button for the storage box, or it can be another button independent of the pairing button.

[0222] Step S1102: In response to detecting that a button has been triggered, the storage box determines whether the earphones are in place.

[0223] In other words, the storage box detects whether earphones are inside. When at least one earphone is inside, the storage box determines that the earphones are present. This can include cases where the first earphone is inside, cases where the second earphone is inside, and cases where both the first and second earphones are inside. When no earphones are inside, the storage box determines that the earphones are not present.

[0224] When the earphones are placed in the charging case, their contacts abut against and electrically connect with the spring contacts in the case. The charging case detects this and initiates a charging process. Upon detecting the first event, the charging process is interrupted, and a stethoscope-like function is entered. For example, a button interrupt handler and a timer can be set in the processor's program. The button interrupt handler is a hardware-level operation; it captures a button press, temporarily stores the current program's data, and jumps to the program triggered by the button. The timer counts the number of times the button interrupt handler is entered within a specified time. If the preset number of entries is met, the processor switches to the stethoscope-like function; otherwise, the count is reset to zero, waiting for the next trigger.

[0225] Step S1103: If the storage box determines that the earphones are in place, the storage box determines whether it is in a closed state.

[0226] The storage box can determine whether its lid is open, closed, or in another state through its Hall sensor or other components, thereby determining whether the storage box is in a closed, open, or other state.

[0227] Step S1104: If the storage box determines that the earphones are not in place, the storage box control indicator light performs the first action.

[0228] The storage box includes indicator lights. The first action can be a long flash, a short flash, a slow flash, or a constant light.

[0229] Step S1104 may further include, after the indicator light performs the first action, within a first time period, the storage box re-determines whether the earphone is in place; if yes, then step S1103 is executed; if no, then the process ends.

[0230] Step S1104 is an optional step, and there is no order requirement between step S1104 and step S1103.

[0231] Step S1105: If it is determined that the storage box is in a closed state, the storage box sends the first information to the earphone.

[0232] Step S1106: If it is determined that the storage box is not in a closed state, the storage box control indicator light will perform the second action.

[0233] The second action can be a long flash, a short flash, a slow flash, or a constant light. The first and second actions of the indicator light may differ. For example, the flashing pattern of the second action may differ from the flashing pattern of the first action, or the flashing duration of the second action may differ from the flashing duration of the first action, or the number of flashes of the second action may differ from the number of flashes of the first action.

[0234] Step S1106 may further include, after the indicator light performs the second action, during the second time period, the storage box again determines whether it is in a closed state; if yes, then step S1105 is executed; if no, then the process ends.

[0235] Step S1106 is an optional step, and there is no order requirement between steps S1106 and S1105.

[0236] In steps S1104 and S1106, before the method ends, the storage box can control the indicator light to perform a third action to notify the user that the sound collection method has ended. This third action can be a long flash, a short flash, a slow flash, or a constant light. The third action differs from the first and second actions, for example, in the flashing pattern, flashing duration, or number of flashes.

[0237] Step S1107: The earphone receives the first information.

[0238] For example, the storage box can send the first information to the earphone's contact points through its spring contacts, so that the earphone receives the first information.

[0239] Step S1108: In response to receiving the first information, the earphone turns on the microphone and collects the first sound through the sound collection device.

[0240] In this embodiment, the earphones are placed in a storage case, and the earphones can collect a first sound through the sound collection device of the storage case. Exemplarily, the first sound can be human physiological sounds, such as sound signals produced by the heart, lungs, intestines, or arteries. In other embodiments, auscultation sounds can also be physiological sounds of other animals, or faint sounds from the external environment, equipment, etc.

[0241] In step S1108, the duration for which the earphone collects the first sound can be a fixed duration, which can be less than or equal to 40 seconds, such as 15 seconds, 20 seconds, 25 seconds, 30 seconds, etc.

[0242] This step may also include: in response to receiving the first information, the headset disables the microphone startup dependency.

[0243] The microphone activation dependency of the headphones is as follows: the headphones' wear sensor detects that the headphones are being worn. That is, when the microphone activation dependency is enabled, the headphones can only activate the microphone when the headphones are being worn. In this step, by disabling the microphone activation dependency, the headphones can activate the microphone even when not being worn (e.g., when placed in the storage case), thereby enabling sound acquisition upon instruction from the first information.

[0244] Step S1109: The headphones store the first sound.

[0245] The headphones can store the first sound they capture in their own memory for later retrieval and / or processing.

[0246] In step S1109, the earphone may also mark the first sound as needing synchronization. In this embodiment, marking the first sound by the earphone is beneficial for subsequent processing of the first sound by the communication system. In some other embodiments, the first sound may not be marked in step S1109.

[0247] In this embodiment of the application, when the storage box determines whether the earphones are in place, it can determine the number and position of the earphones in place, and subsequent steps of the sound acquisition method can be set accordingly based on the number and position of the earphones in place. For example:

[0248] In some usage scenarios, the storage box can determine that the present earphones include the first earphone and the second earphone. Then: in step S1105, the storage box sends a first message to the first earphone and the second earphone; in step S1107, both the first earphone and the second earphone receive the first message; in steps S1108 and S1109, the first earphone and the second earphone respond to the first message, turn on their microphones, collect the first sound through the sound collection device, and store it in their own memory.

[0249] In this embodiment, since both the first earphone and the second earphone collect the first sound, the sound acquisition method can collect the first sound of higher quality, which is beneficial to improving the accuracy of the analysis results based on the first sound.

[0250] In other use cases, if the storage box can determine that the present earphones include the first earphone, then: in step S1105, the storage box sends a first message to the first earphone; in step S1107, the first earphone receives the first message; in steps S1108 and S1109, in response to the first message, the first earphone turns on its microphone, collects the first sound through the sound collection device, and stores it in its own memory.

[0251] The communication system also includes a second earphone located outside the storage box. The sound acquisition method also includes:

[0252] Step S1110: In response to receiving the first information, the first earphone determines whether to connect to the second earphone.

[0253] At this time, the first information includes a message instructing the first earphone to collect the first sound, and also includes a message instructing the first earphone to determine the status of the second earphone.

[0254] The first information includes information that the first earphone is in place and the second earphone is not in place. After receiving the first information, the first earphone turns on Bluetooth to connect to the second earphone.

[0255] Step S1111: If it is determined that the second earphone is connected, the first earphone determines whether the second earphone is being worn.

[0256] The first earphone can send wearing status detection information to the second earphone. The second earphone receives and responds to the wearing status detection information, determines whether it is in a wearing state, and sends a confirmation message (i.e., in a wearing state or not in a wearing state) to the first earphone. The first earphone receives the confirmation message.

[0257] Step S1112: If it is determined that the second earphone is being worn, the first earphone will send the first sound it has collected to the second earphone.

[0258] Step S1113: The second earphone receives the first sound.

[0259] Step S1114: The second earphone responds to receiving the first sound and plays the first sound.

[0260] In this embodiment, the sound acquisition method can acquire the first sound through the first earphone and play the first sound through the second earphone, thereby realizing sound acquisition and real-time listening, resulting in a good user experience.

[0261] The sound acquisition method further includes: if it is determined that the second earphone is not being worn, the first earphone disconnects from the second earphone; in addition, the sound acquisition method no longer executes the subsequent steps S1113 and S1114.

[0262] In some embodiments, in the sound acquisition method, when two earphones of an earphone assembly are connected, with one earphone located inside a charging case and the other earphone located outside the charging case and in a wearing state, if the earphone inside the charging case acquires a stethoscope sound, the earphone outside the charging case can play a first prompt tone; if the earphone inside the charging case fails to acquire a stethoscope sound, the earphone outside the charging case can play a second prompt tone. The second prompt tone is different from the first prompt tone.

[0263] A second embodiment of the sound acquisition steps in the sound acquisition method:

[0264] Please see Figure 27 , Figure 27 This is a flowchart illustrating some steps of the sound acquisition method provided in this application in a second embodiment. Figure 27 The diagram mainly illustrates the sound acquisition steps of the sound acquisition method.

[0265] In the second embodiment, the sound acquisition method may include:

[0266] Step S1201: The terminal receives the user's trigger operation.

[0267] The terminal's display interface can feature a stethoscope icon. The user's trigger action is touching the stethoscope icon; when touched, the terminal enters the stethoscope program. Alternatively, the user's trigger action can be other actions such as voice control or mechanical button control, which will also initiate the sound acquisition program.

[0268] Step S1202: In response to receiving the user's trigger operation, the terminal determines whether to connect the headphones.

[0269] The scenarios where the terminal connects to headphones include situations where the terminal connects to one earphone from the headphone assembly, and situations where the terminal connects to both earphones from the headphone assembly. Typically, when the terminal connects to headphones, it connects to both earphones from the headphone assembly.

[0270] Step S1203: If the connection of the headphones is confirmed, the terminal will prompt you to put the headphones into the storage case.

[0271] In this step, the terminal prompts the user to place the earphones into the storage case to put them back in their proper place. The terminal may prompt the user to place one or both earphones into the storage case.

[0272] Step S1204: If the connection to the headset is confirmed, the terminal sends detection information to the headset.

[0273] There is no fixed order for steps S1203 and S1204; they can be performed one after the other or simultaneously.

[0274] Step S1205: If it is determined that the headphones are not connected, the terminal may prompt the user to reconnect the headphones.

[0275] In step S1205, the terminal may further include, after being prompted to reconnect the headphones, re-determining whether to reconnect the headphones within a certain period of time; if yes, the terminal prompts the user to put the headphones into the storage box; if no, the terminal terminates the sound acquisition program.

[0276] Step S1205 is an optional step.

[0277] Step S1206: The earphone receives detection information.

[0278] Step S1207: In response to receiving the detection information, the earphone sends the detection information to the storage box.

[0279] The detection information sent by the terminal to the earphone and the detection information sent by the earphone to the storage box both carry content for instructing the storage box to perform corresponding determination steps. These two detection information can be represented by different protocols, carriers, etc., and this application embodiment does not strictly limit them.

[0280] In some embodiments, the earphones send detection information to the charging case when they have sufficient power. Sufficient power means the earphones' battery level is higher than or equal to a set threshold. The charging case can detect the earphone battery level. If the earphones are low on power, the terminal can prompt the user to charge the earphones and then end the stethoscope procedure.

[0281] Step S1208: The storage box receives the detection information.

[0282] Step S1209: In response to receiving the detection information, the storage box determines whether the earphones are in place.

[0283] Step S1210: If it is confirmed that the earphone is in place, the storage box sends a first confirmation message to the earphone.

[0284] Step S1211: The headset receives the first confirmation information and sends it to the terminal.

[0285] Step S1212: The terminal receives the first confirmation information.

[0286] Step S1213: In response to receiving the first confirmation information, the terminal prompts the user to close the storage box.

[0287] Steps S1210 to S1213 are optional.

[0288] In step S1209, if it is determined that the earphone is not in place, the storage box can send a first reminder message to the earphone. The earphone receives the first reminder message and sends it to the terminal. The terminal receives the first reminder message and responds by prompting the earphone to be placed in the storage box. The storage box re-determines whether the earphone is in place within the first time period. If the earphone is in place, step S1210 and subsequent steps are executed. If the earphone is not in place, the terminal ends the sound acquisition program.

[0289] Step S1214: If the earphones are confirmed to be in place, the storage box determines whether it is in a closed state.

[0290] There is no specific order requirement for steps S1210 and S1214.

[0291] Step S1215: If it is determined that the storage box is in a closed state, the storage box sends a second confirmation message to the earphone.

[0292] Step S1216: The headset receives the second confirmation information and sends it to the terminal.

[0293] In step S1214, if it is determined that the storage box is not in a closed state, the storage box can send a second reminder message to the earphone. The earphone receives the second reminder message and sends it to the terminal. The terminal receives the second reminder message and responds by prompting the storage box to close. The storage box re-determines whether it is in a closed state within the second time period. If it is, step S1215 and subsequent steps are executed. If not, the terminal ends the sound acquisition program.

[0294] Specifically, in steps S1207 to S1209 and steps S1214 to S1216, the earphone can determine whether it is in place and whether the storage box is in a closed state. When the earphone receives the second confirmation information, it can determine that it is in place and the storage box is in a closed state, and then the earphone sends the second confirmation information to the terminal.

[0295] In some other embodiments, after receiving the first confirmation information, the earphone may also send status detection information to the storage box in response to receiving the first confirmation information; the storage box receives the status detection information and determines whether it is in a closed state in response to receiving the status detection information. The remaining steps are the same as in the aforementioned embodiments and will not be repeated here.

[0296] Step S1217: The terminal receives the second confirmation information.

[0297] Step S1218: The terminal responds to receiving the second confirmation information and prompts the user to place the storage box at the sound acquisition location.

[0298] Step S1218 is an optional step.

[0299] Step S1219: In response to receiving the second confirmation information, the terminal sends the second information to the headset.

[0300] Step S1220: The earphone receives the second information and sends it to the storage box.

[0301] Step S1221: The storage box receives the second information.

[0302] Specifically, when the storage box receives the second information, the storage box detects the first event.

[0303] Step S1222: In response to receiving the second information, the storage box determines whether the earphones are in place and whether the storage box is in a closed state.

[0304] The process of determining whether the earphones are in place and whether the storage box is in a closed state can include: the storage box determining whether the earphones are in place; if the earphones are determined to be in place, then determining whether the storage box is in a closed state.

[0305] Step S1223: If it is determined that the earphone is in place and the storage box is in a closed state, the storage box sends the first information to the earphone.

[0306] The detailed scheme of the steps after the storage box receives the second information (i.e., steps S1222 and S1223) can be referred to the relevant description of steps S1102 to S1106 in the previous embodiment, and will not be repeated here.

[0307] Step S1224: The earphone receives the first information.

[0308] For example, the storage box can send the first information to the earphone's contact points through its spring contacts, so that the earphone receives the first information.

[0309] Step S1225: In response to receiving the first information, the earphone turns on the microphone and collects the first sound through the sound collection device.

[0310] In this embodiment, the earphones are placed in a storage case, and the earphones can collect a first sound through the sound collection device of the storage case. Exemplarily, the first sound can be human physiological sounds, such as sound signals produced by the heart, lungs, intestines, or arteries. In other embodiments, auscultation sounds can also be physiological sounds of other animals, or faint sounds from the external environment, equipment, etc.

[0311] In step S1225, the duration for which the earphone collects the first sound can be a fixed duration, which can be less than or equal to 40 seconds, such as 15 seconds, 20 seconds, 25 seconds, 30 seconds, etc.

[0312] Step S1226: The headphones store the first sound.

[0313] The earphone can store the acquired first sound in its own memory for later retrieval and / or processing. In step S1226, the earphone can also mark the first sound as needing synchronization. In this embodiment, marking the first sound by the earphone facilitates subsequent processing of the first sound by the communication system. In some other embodiments, the first sound may not be marked in step S1226.

[0314] In this embodiment of the application, when the storage box determines whether the earphones are in place, the number and position of the earphones in place can be determined. The subsequent steps of the sound acquisition method can be set accordingly based on the number and position of the earphones in place. The relevant description can be referred to the previous embodiment, and will not be repeated here.

[0315] In the second embodiment, the sound acquisition method may further include:

[0316] Step S1227: In response to receiving the detection information, the headset maintains its connection with the terminal.

[0317] Step S1228: In response to receiving the second information, the headset disconnects from the terminal.

[0318] In this embodiment, when the earphone assembly is in normal audio mode, if the earphone is in place and the charging case is closed, the earphone will turn off Bluetooth to disconnect from the terminal, and communication between the earphone and the terminal will be impossible. When the earphone assembly is in sound acquisition mode, by ensuring that the earphone maintains a connection with the terminal regardless of whether the charging case is closed until the second information is received (e.g., by keeping the earphone's Bluetooth on), communication between the earphone and the terminal can be ensured, guaranteeing smooth communication during the execution of the sound acquisition method. Furthermore, the earphone can also promptly turn off Bluetooth and disconnect from the terminal after receiving the second information to enter a low-power mode.

[0319] The headset can also maintain its connection with the terminal in response to receiving the first confirmed information.

[0320] Specifically, during the process of maintaining the connection between the headphones and the terminal, the following may also be included: increasing the wireless communication power of the headphones, for example, when the headphones and the terminal are connected via Bluetooth, increasing the Bluetooth power to compensate for the attenuation of the wireless signal caused by the headphones being placed in the storage case, so as to make the wireless communication between the headphones and the terminal highly reliable.

[0321] In the second embodiment, the sound acquisition method may further include:

[0322] Step S1229: In response to receiving the first message, the headset disables the microphone dependency.

[0323] The microphone activation dependency of the headphones is as follows: the headphones' wear sensor detects that the headphones are being worn. That is, when the microphone activation dependency is enabled, the headphones can only activate the microphone when the headphones are being worn. In this step, by disabling the microphone activation dependency, the headphones can activate the microphone even when not being worn (e.g., when placed in the storage case), thereby enabling sound acquisition upon instruction from the first information.

[0324] In some other embodiments, steps S1207 to S1216 can also be replaced with:

[0325] Step S1230: The earphone responds to the received detection information and determines whether it is in position.

[0326] When the earphones are placed in the storage case, their contacts make contact with the spring contacts of the storage case, thus confirming that the earphones are in place.

[0327] Step S1231: The headset sends the first confirmation message to the terminal.

[0328] Step S1232: The terminal receives the first confirmation information.

[0329] Step S1233: In response to receiving the first confirmation information, the terminal prompts the user to close the storage box.

[0330] Steps S1231 to S1233 are optional.

[0331] Step S1234: If it is determined that the earphone is in place, the earphone sends status detection information to the storage box.

[0332] Step S1235: The storage box receives status detection information.

[0333] Step S1236: In response to the received status detection information, the storage box determines whether it is in a closed state.

[0334] Step S1237: If it is determined that the storage box is in a closed state, the storage box sends a second confirmation message to the earphone.

[0335] Step S1238: The headset receives the second confirmation information and sends it to the terminal.

[0336] In steps S1230 and S1234 to S1237, the earphone determines whether it is in place and whether the storage box is closed. Upon receiving the second confirmation information, the earphone determines that it is in place and the storage box is closed, and then sends the second confirmation information to the terminal.

[0337] The remaining steps are the same as those in the previous embodiments, and will not be repeated here.

[0338] The third embodiment of the sound acquisition steps in the sound acquisition method:

[0339] Please see Figure 28 , Figure 28 This is a flowchart illustrating some steps of the sound acquisition method provided in this application in the third embodiment. Figure 28 The diagram mainly illustrates the sound acquisition steps of the sound acquisition method.

[0340] In the third embodiment, the sound acquisition method may include:

[0341] Step S1301: The terminal receives the user's trigger operation.

[0342] The terminal's display interface can feature a stethoscope icon. The user's trigger action is touching the stethoscope icon; when touched, the terminal enters the stethoscope program. Alternatively, the user's trigger action can be other actions such as voice control or mechanical button control, which will also initiate the sound acquisition program.

[0343] Step S1302: In response to receiving the user's trigger operation, the terminal determines whether to connect the headphones.

[0344] The scenarios where the terminal connects to headphones include situations where the terminal connects to one earphone from the headphone assembly, and situations where the terminal connects to both earphones from the headphone assembly. Typically, when the terminal connects to headphones, it connects to both earphones from the headphone assembly.

[0345] Step S1303: If it is confirmed that the headset is connected, the terminal sends third information to the headset.

[0346] Step S1304: If the connection of the headphones is confirmed, the terminal will prompt you to put the headphones into the storage case.

[0347] In this step, the terminal prompts the user to place the earphones into the storage case to put them back in their proper place. The terminal may prompt the user to place one or both earphones into the storage case.

[0348] Step S1305: If the connection of the headphones is confirmed, the terminal will prompt you to close the storage case.

[0349] Step S1306: If the headphones are connected, the terminal will prompt you to place the storage box at the sound acquisition location.

[0350] In this embodiment, there is no strict order requirement between steps S1304 and S1303. Steps S1304 to S1306 can be performed sequentially or simultaneously. The relevant prompts for steps S1304 to S1306 can be displayed on the same or different display interfaces on the terminal; this embodiment does not impose strict limitations on this. Through steps S1304 to S1306, the user, following the terminal's prompts, places the earphones into the storage case, closes the storage case, and places the storage case at the sound acquisition position, enabling the user to successfully acquire sound using the sound acquisition method.

[0351] Step S1307: The earphone receives the third information and sends it to the storage box.

[0352] Step S1308: The storage box receives third-party information.

[0353] When the storage box receives the third information, it detects the first event.

[0354] Step S1309: In response to receiving the third information, the storage box determines whether the earphones are in place and whether the storage box is in a closed state.

[0355] The process of determining whether the earphones are in place and whether the storage box is in a closed state can include: the storage box determining whether the earphones are in place; if the earphones are determined to be in place, then determining whether the storage box is in a closed state.

[0356] Step S1310: If it is determined that the earphone is in place and the storage box is in a closed state, the storage box sends the first information to the earphone.

[0357] The detailed scheme of the steps after the storage box receives the third information (i.e., steps S1309 and S1310) can be referred to the relevant descriptions of steps S1102 to S1106 in the previous embodiment, and will not be repeated here.

[0358] Step S1311: The earphone receives the first information.

[0359] For example, the storage box can send the first information to the earphone's contact points through its spring contacts, so that the earphone receives the first information.

[0360] Step S1312: In response to receiving the first information, the earphone turns on the microphone and collects the first sound through the sound collection device.

[0361] In this embodiment, the earphones are placed in a storage case, and the earphones can collect a first sound through the sound collection device of the storage case. Exemplarily, the first sound can be human physiological sounds, such as sound signals produced by the heart, lungs, intestines, or arteries. In other embodiments, auscultation sounds can also be physiological sounds of other animals, or faint sounds from the external environment, equipment, etc.

[0362] In step S1312, the duration for which the earphone collects the first sound can be a fixed duration, which can be less than or equal to 40 seconds, such as 15 seconds, 20 seconds, 25 seconds, 30 seconds, etc.

[0363] Step S1313: The headphones store the first sound.

[0364] The earphone can store the acquired first sound in its own memory for later retrieval and / or processing. In step S1313, the earphone can also mark the first sound as needing synchronization. In this embodiment, marking the first sound by the earphone facilitates subsequent processing of the first sound by the communication system. In some other embodiments, the first sound may not be marked in step S1313.

[0365] In this embodiment of the application, when the storage box determines whether the earphones are in place, the number and position of the earphones in place can be determined. The subsequent steps of the sound acquisition method can be set accordingly based on the number and position of the earphones in place. The relevant description can be referred to the previous embodiment, and will not be repeated here.

[0366] The fourth embodiment of the sound acquisition steps in the sound acquisition method:

[0367] Please see Figure 29 , Figure 29 This is a flowchart illustrating some steps of the sound acquisition method provided in this application in the fourth embodiment. Figure 29 The diagram mainly illustrates the sound acquisition steps of the sound acquisition method.

[0368] In the fourth embodiment, the sound acquisition method may include:

[0369] Step S1401: The terminal receives the user's trigger operation.

[0370] The terminal's display interface can feature a stethoscope icon. The user's trigger action is touching the stethoscope icon; when touched, the terminal enters the stethoscope program. Alternatively, the user's trigger action can be other actions such as voice control or mechanical button control, which will also initiate the sound acquisition program.

[0371] Step S1402: In response to receiving the user's trigger operation, the terminal determines whether to connect the headphones.

[0372] The scenarios where the terminal connects to headphones include situations where the terminal connects to one earphone from the headphone assembly, and situations where the terminal connects to both earphones from the headphone assembly. Typically, when the terminal connects to headphones, it connects to both earphones from the headphone assembly.

[0373] Step S1403: If the connection of the headphones is confirmed, the terminal will prompt you to put the headphones into the storage case.

[0374] In this step, the terminal prompts the user to place the earphones into the storage case to put them back in their proper place. The terminal may prompt the user to place one or both earphones into the storage case.

[0375] Step S1404: If it is confirmed that the headset is connected, the terminal sends the fourth information to the headset.

[0376] There is no fixed order for steps S1403 and S1404; they can be performed one after the other or simultaneously.

[0377] Step S1405: If it is determined that the headphones are not connected, the terminal can prompt the user to reconnect the headphones.

[0378] In step S1405, the terminal may further include, after being prompted to reconnect the headphones, re-determining whether to reconnect the headphones within a certain period of time; if yes, the terminal prompts the user to put the headphones into the storage box; if no, the terminal terminates the sound acquisition program.

[0379] Step S1405 is an optional step.

[0380] Step S1406: The earphone receives the fourth information.

[0381] Step S1407: In response to receiving the fourth information, the earphone sends detection information to the storage box.

[0382] In some embodiments, the earphones send detection information to the charging case when they have sufficient power. Sufficient power means the earphones' battery level is higher than or equal to a set threshold. The charging case can detect the earphone battery level. If the earphones are low on power, the terminal can prompt the user to charge the earphones and then end the stethoscope procedure.

[0383] Step S1408: The storage box receives the detection information.

[0384] Step S1409: In response to receiving the detection information, the storage box determines whether the earphones are in place.

[0385] Step S1410: If it is determined that the earphone is in place, the storage box sends a first confirmation message to the earphone.

[0386] Step S1411: The headset receives the first confirmation information and sends it to the terminal.

[0387] Step S1412: The terminal receives the first confirmation information.

[0388] Step S1413: In response to receiving the first confirmation information, the terminal prompts the user to close the storage box.

[0389] Steps S1410 to S1413 are optional.

[0390] In step S1409, if it is determined that the earphone is not in place, the storage box can send a first reminder message to the earphone. The earphone receives the first reminder message and sends it to the terminal. The terminal receives the first reminder message and responds by prompting the earphone to be placed in the storage box. The storage box re-determines whether the earphone is in place within the first time period. If the earphone is in place, step S1410 and subsequent steps are executed. If the earphone is not in place, the terminal ends the sound acquisition program.

[0391] Step S1414: If the earphones are confirmed to be in place, the storage box determines whether it is in a closed state.

[0392] There is no specific order requirement between steps S1410 and S1414.

[0393] Step S1415: If it is determined that the storage box is in a closed state, the storage box sends a second confirmation message to the earphone.

[0394] Step S1416: The headset receives the second confirmation information and sends it to the terminal.

[0395] In step S1414, if it is determined that the storage box is not in a closed state, the storage box can send a second reminder message to the earphone. The earphone receives the second reminder message and sends it to the terminal. The terminal receives the second reminder message and responds by prompting the storage box to close. The storage box re-determines whether it is in a closed state within the second time period. If it is, it continues to execute step S1415 and subsequent steps. If not, the terminal ends the sound acquisition program.

[0396] Specifically, in steps S1407 to S1409 and steps S1414 to S1416, the earphone can determine whether it is in place and whether the storage box is in a closed state. When the earphone receives the second confirmation information, it can determine that it is in place and the storage box is in a closed state, and then the earphone sends the second confirmation information to the terminal.

[0397] In some other embodiments, after receiving the first confirmation information, the earphone may also send status detection information to the storage box in response to receiving the first confirmation information; the storage box receives the status detection information and determines whether it is in a closed state in response to receiving the status detection information. The remaining steps are the same as in the aforementioned embodiments and will not be repeated here.

[0398] Step S1417: The terminal receives the second confirmation information.

[0399] Step S1418: In response to receiving the second confirmation information, the terminal prompts the user to place the storage box at the sound acquisition location.

[0400] Steps S1417 and S1218 are optional. When the sound acquisition method does not include steps S1417 and S1218, step S1416 is replaced by: the earphone receiving the second determination information.

[0401] Step S1419: In response to receiving the second confirmation information, the earphone turns on the microphone and collects the first sound through the sound collection device.

[0402] In this embodiment, the earphones are placed in a storage case, and the earphones can collect a first sound through the sound collection device of the storage case. Exemplarily, the first sound can be human physiological sounds, such as sound signals produced by the heart, lungs, intestines, or arteries. In other embodiments, auscultation sounds can also be physiological sounds of other animals, or faint sounds from the external environment, equipment, etc.

[0403] In step S1419, the duration for which the earphone collects the first sound can be a fixed duration, which can be less than or equal to 40 seconds, such as 15 seconds, 20 seconds, 25 seconds, 30 seconds, etc.

[0404] Step S1420: The headphones store the first sound.

[0405] The earphone can store the acquired first sound in its own memory for later retrieval and / or processing. In step S1420, the earphone can also mark the first sound as needing synchronization. In this embodiment, marking the first sound by the earphone facilitates subsequent processing of the first sound by the communication system. In some other embodiments, the first sound may not be marked in step S1420.

[0406] In this embodiment of the application, when the storage box determines whether the earphones are in place, the number and position of the earphones in place can be determined. The subsequent steps of the sound acquisition method can be set accordingly based on the number and position of the earphones in place. The relevant description can be referred to the previous embodiment, and will not be repeated here.

[0407] In the fourth embodiment, the sound acquisition method may further include:

[0408] Step S1421: In response to receiving the fourth information, the headset maintains its connection with the terminal.

[0409] Step S1422: In response to the second confirmation information, the headset disconnects from the terminal after sending the second confirmation information to the terminal.

[0410] In this embodiment, when the earphone assembly is in normal audio mode, if the earphone is in place and the charging case is closed, the earphone will turn off Bluetooth to disconnect from the terminal, and communication between the earphone and the terminal will be impossible. When the earphone assembly is in sound acquisition mode, by ensuring that the earphone maintains a connection with the terminal regardless of whether the charging case is closed before sending the second determining information to the terminal (e.g., keeping Bluetooth on), communication between the earphone and the terminal can be ensured, thus guaranteeing smooth communication during the execution of the sound acquisition method. Furthermore, the earphone can also promptly turn off Bluetooth and disconnect from the terminal after sending the second determining information to enter a low-power mode.

[0411] The headset can also maintain its connection with the terminal in response to receiving the first confirmed information.

[0412] Specifically, during the process of maintaining the connection between the headphones and the terminal, the following may also be included: increasing the wireless communication power of the headphones, for example, when the headphones and the terminal are connected via Bluetooth, increasing the Bluetooth power to compensate for the attenuation of the wireless signal caused by the headphones being placed in the storage case, so as to make the wireless communication between the headphones and the terminal highly reliable.

[0413] When the sound acquisition method does not include steps S1417 and S1218, the sound acquisition method may not include steps S1421 and S1422.

[0414] In the fourth embodiment, the sound acquisition method may further include:

[0415] Step S1423: In response to receiving the first or second confirmation information, the headset disables the microphone startup dependency.

[0416] The microphone activation dependency of the headphones is as follows: the headphones' wear sensor detects that the headphones are being worn. That is, when the microphone activation dependency is enabled, the headphones can only activate the microphone when the headphones are being worn. In this step, by disabling the microphone activation dependency, the headphones can activate the microphone even when not being worn (e.g., when placed in the storage case), thereby enabling sound acquisition upon instruction from the first information.

[0417] In some other embodiments, steps S1407 to S1416 can also be replaced with:

[0418] Step S1424: In response to receiving the fourth information, the earphone determines whether it is in position.

[0419] When the earphones are placed in the storage case, their contacts make contact with the spring contacts of the storage case, thus confirming that the earphones are in place.

[0420] Step S1425: The headset sends the first confirmation message to the terminal.

[0421] Step S1426: The terminal receives the first confirmation information.

[0422] Step S1427: In response to receiving the first confirmation information, the terminal prompts the user to close the storage box.

[0423] Steps S1425 to S1427 are optional.

[0424] Step S1428: If it is determined that the earphone is in place, the earphone sends status detection information to the storage box.

[0425] Step S1429: The storage box receives status detection information.

[0426] Step S1430: In response to receiving the status detection information, the storage box determines whether it is in a closed state.

[0427] Step S1431: If it is determined that the storage box is in a closed state, the storage box sends a second confirmation message to the earphone.

[0428] Step S1432: The headset receives the second confirmation information and sends it to the terminal.

[0429] In steps S1424 and S1428 to S1431, the earphone determines whether it is in place and whether the storage box is closed. Upon receiving the second confirmation information, the earphone determines that it is in place and the storage box is closed, and then sends the second confirmation information to the terminal.

[0430] The remaining steps are the same as those in the previous embodiments, and will not be repeated here.

[0431] The fifth embodiment of the sound acquisition steps in the sound acquisition method:

[0432] Please see Figure 30 , Figure 30 This is a flowchart illustrating some steps of the sound acquisition method provided in this application in the fifth embodiment. Wherein, Figure 30 The diagram mainly illustrates the sound acquisition steps of the sound acquisition method.

[0433] In the fifth embodiment, the sound acquisition method may include:

[0434] Step S1501: The terminal receives the user's trigger operation.

[0435] The terminal's display interface can feature a stethoscope icon. The user's trigger action is touching the stethoscope icon; when touched, the terminal enters the stethoscope program. Alternatively, the user's trigger action can be other actions such as voice control or mechanical button control, which will also initiate the sound acquisition program.

[0436] Step S1502: In response to receiving the user's trigger operation, the terminal determines whether to connect the headphones.

[0437] The scenarios where the terminal connects to headphones include situations where the terminal connects to one earphone from the headphone assembly, and situations where the terminal connects to both earphones from the headphone assembly. Typically, when the terminal connects to headphones, it connects to both earphones from the headphone assembly.

[0438] Step S1503: If it is confirmed that the headset is connected, the terminal sends the fourth information to the headset.

[0439] Step S1504: If the connection of the headphones is confirmed, the terminal will prompt you to put the headphones into the storage case.

[0440] In this step, the terminal prompts the user to place the earphones into the storage case to put them back in their proper place. The terminal may prompt the user to place one or both earphones into the storage case.

[0441] Step S1505: If the connection of the headphones is confirmed, the terminal will prompt you to close the storage case.

[0442] Step S1506: If the headphones are connected, the terminal will prompt you to place the storage box at the sound acquisition location.

[0443] In this embodiment, there is no strict order requirement between steps S1504 and S1503. Steps S1504 to S1506 can be performed sequentially or simultaneously. The relevant prompts for steps S1504 to S1506 can be displayed on the same or different display interfaces on the terminal; this embodiment does not impose strict limitations on this. Through steps S1504 to S1506, the user, following the terminal's prompts, places the earphones into the storage case, closes the storage case, and places the storage case at the sound acquisition position, enabling the user to successfully acquire sound using the sound acquisition method.

[0444] Step S1507: In response to receiving the fourth information, the earphone sends detection information to the storage box.

[0445] In some embodiments, the earphones send detection information to the charging case when they have sufficient power. Sufficient power means the earphones' battery level is higher than or equal to a set threshold. The charging case can detect the earphone battery level. If the earphones are low on power, the terminal can prompt the user to charge the earphones and then end the stethoscope procedure.

[0446] Step S1508: The storage box receives the detection information.

[0447] Step S1509: In response to receiving the detection information, the storage box determines whether the earphones are in place and whether the storage box is in a closed state.

[0448] The process of determining whether the earphones are in place and whether the storage box is in a closed state can include: the storage box determining whether the earphones are in place; if the earphones are determined to be in place, then determining whether the storage box is in a closed state.

[0449] Step S1510: If it is determined that the earphone is in place and the storage box is in a closed state, the storage box sends a confirmation message to the earphone.

[0450] Step S1511: The headset receives the confirmation message.

[0451] Step S1512: In response to receiving the confirmation information, the earphone turns on the microphone and collects the first sound through the sound collection device.

[0452] In this embodiment, the earphones are placed in a storage case, and the earphones can collect a first sound through the sound collection device of the storage case. Exemplarily, the first sound can be human physiological sounds, such as sound signals produced by the heart, lungs, intestines, or arteries. In other embodiments, auscultation sounds can also be physiological sounds of other animals, or faint sounds from the external environment, equipment, etc.

[0453] In step S1512, the duration for which the earphone collects the first sound can be a fixed duration, which can be less than or equal to 40 seconds, such as 15 seconds, 20 seconds, 25 seconds, 30 seconds, etc.

[0454] Step S1513: The headphones store the first sound.

[0455] The earphone can store the acquired first sound in its own memory for later retrieval and / or processing. In step S1513, the earphone can also mark the first sound as needing synchronization. In this embodiment, marking the first sound by the earphone facilitates subsequent processing of the first sound by the communication system. In some other embodiments, the first sound may not be marked in step S1513.

[0456] In this embodiment of the application, when the storage box determines whether the earphones are in place, the number and position of the earphones in place can be determined. The subsequent steps of the sound acquisition method can be set accordingly based on the number and position of the earphones in place. The relevant description can be referred to the previous embodiment, and will not be repeated here.

[0457] Multiple embodiments of the sound acquisition steps of the sound acquisition method can be combined with each other, and the sound acquisition method can acquire sound through one or more of the above embodiments.

[0458] The first implementation method for the sound processing steps of the sound acquisition method:

[0459] In some embodiments, please refer to Figure 31 , Figure 31 This is a partial flowchart of another part of the steps in the first implementation of the sound acquisition method provided in this application. Unless otherwise specified, Figure 31 The steps shown can be compared with Figures 27 to 30 The steps shown are combined.

[0460] After the headphones capture the first sound, the sound acquisition method also includes:

[0461] Step S2101: The storage box determines whether it is open and whether the earphones are in place.

[0462] The process of determining whether the charging case is open and whether the earphones are in place includes: the charging case determining whether it is open; and if it is open, the charging case determining whether the earphones are in place. "Earphones in place" includes both cases.

[0463] Step S2102: If it is confirmed that the storage box is open and the earphones are in place, the storage box sends the fifth message to the earphones.

[0464] Step S2103: The earphone receives the fifth information.

[0465] Step S2104: In response to receiving the fifth message, the headset determines whether to connect to the terminal.

[0466] Step S2105: If the connection to the terminal is confirmed, the headset determines whether there is a first sound marked as to be synchronized.

[0467] Step S2106: If it is determined that there is a first sound marked as to be synchronized, the headset will send the first sound marked as to be synchronized to the terminal.

[0468] During the transmission of the first sound from the earphones to the terminal, the earphones can be located either outside or inside the charging case. If the earphones remain inside the charging case, they can increase their wireless communication power to compensate for the signal attenuation caused by placing them inside the charging case, thus ensuring high reliability of wireless communication between the earphones and the terminal. When the earphones transmit the stethoscope tone to the terminal with the charging case open, the power consumption for connection and signal transmission is low, resulting in high signal transmission reliability.

[0469] During the process of the earphones sending the first sound to the terminal, if the earphones are still in the storage case, the storage case can control the indicator light to perform a fourth action to provide a notification. The fourth action can be a long flash, a short flash, a slow flash, or a constant light. This fourth action differs from the first three actions, for example, in terms of flashing pattern, flashing duration, or flashing frequency.

[0470] If it is determined that there is no first sound marked as to be synchronized, the process ends.

[0471] Step S2107: The terminal receives the first sound.

[0472] Step S2108: The terminal responds to receiving the first sound and prompts that the transmission was successful.

[0473] In this step, the terminal may also prompt the user to recall the first sound or the analysis results to remind them to perform subsequent operations. This step is optional.

[0474] In this embodiment, the earphone can send information to the terminal, which then invokes it. Upon receiving the first sound transmitted from the earphone, the terminal can indicate receipt of the first sound. In this embodiment, when the earphone sends the first sound to the terminal, the terminal can provide a notification through a display interface at the operating system level, such as an icon on the desktop, eliminating the need for a specific app, thus simplifying the operation process.

[0475] Step S2109: In response to receiving the first sound, the terminal determines whether the user has invoked the first sound.

[0476] In this embodiment, the user can invoke the first sound by operating the terminal's display screen, buttons, or other components, or by using voice input. This application does not strictly limit the specific method by which the user invokes the first sound. Correspondingly, the terminal can determine whether the user has invoked the first sound through components such as the display screen, buttons, and microphone.

[0477] Step S2110: If it is determined that the user calls the first sound, the terminal outputs the first sound.

[0478] The terminal outputting the first sound may include: the terminal playing the first sound through a speaker; and / or the terminal displaying the waveform of the first sound on a display screen.

[0479] Step S2111: The terminal responds to receiving the first sound and determines whether the user wants to view the analysis results.

[0480] Users can confirm and view the analysis results by operating the terminal's display screen, buttons, or other components, or by using voice input. This application embodiment does not strictly limit the specific operation method by which the user confirms and views the analysis results. Correspondingly, the terminal can determine whether the user has viewed the analysis results through components such as the display screen, buttons, and microphone.

[0481] Step S2112: If it is determined that the user will view the analysis results, the terminal will generate analysis results based on the first sound and display the analysis results on the screen.

[0482] The terminal can use algorithms to analyze the first sound and generate analysis results.

[0483] There is no specific order requirement between steps S2111 and S2109.

[0484] In some embodiments, the sound acquisition method may further include:

[0485] Step S2113: After the headset sends the first sound marked as to be synchronized to the terminal, the headset marks the first sound that has been sent to the terminal as synchronized.

[0486] In this step, the headphones distinguish the first sound that has already been sent to the terminal from the first sound that has not been sent to the terminal (i.e., the first sound marked as pending synchronization). This facilitates the management of the sound in the headphones' memory, avoids repeatedly sending the same sound, and also saves on sound processing steps, improving efficiency. In some other embodiments, the sound acquisition method may not mark the first sound; that is, the sound acquisition method omits the process of marking the first sound as pending or synchronized. When connected to the terminal, the headphones can send part or all of the sound in their memory to the terminal in response to the transmission information received by the terminal.

[0487] In the above embodiments, the earphones transmit the first sound to the terminal when the charging case is open. In other embodiments, the earphones can also transmit the first sound to the terminal when the charging case is closed. In this case, after collecting the first sound, the earphones can reactivate Bluetooth or other wireless communication components, connect to the terminal, and then proceed with the subsequent transmission of the first sound. The earphones can increase their wireless communication power to compensate for the attenuation of the wireless signal caused by placing the earphones in the charging case, thus ensuring high reliability of wireless communication between the earphones and the terminal.

[0488] In some embodiments, the sound acquisition method may further include:

[0489] When the terminal is connected to the headphones and the headphones are being worn, the terminal can send a play command to the headphones, which will then play the first sound stored in the headphones according to the play command. When both headphones are being worn, both headphones can play; when only one headphone is being worn, only that headphone plays. The stethoscope sounds stored in the headphones include the first sounds stored in both headphones.

[0490] A second implementation method for the sound processing steps of the sound acquisition method:

[0491] In some embodiments, please refer to Figure 32 , Figure 32 This is a partial flowchart of another part of the steps in the second implementation of the sound acquisition method provided in this application. Unless otherwise specified, Figure 32 The steps shown can be compared with Figures 27 to 30 The steps shown are combined.

[0492] After the headphones capture the first sound, the sound acquisition method also includes:

[0493] Step S2201: The storage box determines whether it is open and whether the earphones are in place.

[0494] The process of determining whether the charging case is open and whether the earphones are in place includes: the charging case determining whether it is open; and if it is open, the charging case determining whether the earphones are in place. "Earphones in place" includes both cases.

[0495] Step S2202: If it is confirmed that the storage box is open and the earphones are in place, the storage box sends the fifth message to the earphones.

[0496] Step S2203: The earphone receives the fifth message.

[0497] Step S2204: In response to receiving the fifth message, the headset determines whether to connect to the terminal.

[0498] Step S2205: If the connection to the terminal is confirmed, the headset determines whether there is a first sound marked as to be synchronized.

[0499] Step S2206: If it is determined that there is a first sound marked as to be synchronized, the headset sends a synchronization request to the terminal.

[0500] Step S2207: The terminal receives the request synchronization information.

[0501] Step S2208: In response to receiving the synchronization request information, the terminal determines whether to synchronize the sound.

[0502] In this embodiment, the user can determine whether to synchronize the first sound by operating the terminal's display screen, buttons, or other components, or by using voice input. This application does not strictly limit the specific method by which the user determines the synchronization of the first sound. Correspondingly, the terminal can determine whether the user is synchronizing the first sound through components such as the display screen, buttons, and microphone.

[0503] Step S2209: If synchronized sound is confirmed, the terminal sends synchronization information to the headset;

[0504] Step S2210: The headphones receive synchronization information.

[0505] Through steps S2206 to S2210, the headset can determine whether it has received synchronization information.

[0506] Step S2211: In response to receiving synchronization information, the headset sends the first sound marked as to be synchronized to the terminal.

[0507] During the transmission of the first sound from the earphones to the terminal, the earphones can be located either outside or inside the charging case. If the earphones remain inside the charging case, they can increase their wireless communication power to compensate for the signal attenuation caused by placing them inside the charging case, thus ensuring high reliability of wireless communication between the earphones and the terminal. When the earphones transmit the stethoscope tone to the terminal with the charging case open, the power consumption for connection and signal transmission is low, resulting in high signal transmission reliability.

[0508] During the process of the earphones sending the first sound to the terminal, if the earphones are still in the storage case, the storage case can control the indicator light to perform a fourth action to provide a notification. The fourth action can be a long flash, a short flash, a slow flash, or a constant light. This fourth action differs from the first three actions, for example, in terms of flashing pattern, flashing duration, or flashing frequency.

[0509] If it is determined that there is no first sound marked as to be synchronized, the process ends.

[0510] Step S2212: The terminal receives the first sound.

[0511] Step S2213: The terminal responds to receiving the first sound and prompts that the transmission was successful.

[0512] In this step, the terminal may also prompt the user to recall the first sound or the analysis results to remind them to perform subsequent operations. This step is optional.

[0513] In this embodiment, the earphone can send information to the terminal, which then invokes it. Upon receiving the first sound transmitted from the earphone, the terminal can indicate receipt of the first sound. In this embodiment, when the earphone sends the first sound to the terminal, the terminal can provide a notification through a display interface at the operating system level, such as an icon on the desktop, eliminating the need for a specific app, thus simplifying the operation process.

[0514] Step S2214: In response to receiving the first sound, the terminal determines whether the user has invoked the first sound.

[0515] In this embodiment, the user can invoke the first sound by operating the terminal's display screen, buttons, or other components, or by using voice input. This application does not strictly limit the specific method by which the user invokes the first sound. Correspondingly, the terminal can determine whether the user has invoked the first sound through components such as the display screen, buttons, and microphone.

[0516] Step S2215: If it is determined that the user calls the first sound, the terminal outputs the first sound.

[0517] The terminal outputting the first sound may include: the terminal playing the first sound through a speaker; and / or the terminal displaying the waveform of the first sound on a display screen.

[0518] Step S2216: The terminal responds to receiving the first sound and determines whether the user wants to view the analysis results.

[0519] Users can confirm and view the analysis results by operating the terminal's display screen, buttons, or other components, or by using voice input. This application embodiment does not strictly limit the specific operation method by which the user confirms and views the analysis results. Correspondingly, the terminal can determine whether the user has viewed the analysis results through components such as the display screen, buttons, and microphone.

[0520] Step S2217: If it is determined that the user will view the analysis results, the terminal will generate analysis results based on the first sound and display the analysis results on the screen.

[0521] The terminal can use algorithms to analyze the first sound and generate analysis results.

[0522] There is no specific order requirement for steps S2214 and S2216.

[0523] In some embodiments, the sound acquisition method may further include:

[0524] Step S2218: After the headphones send the first sound marked as to be synchronized to the terminal, the headphones mark the first sound that has been sent to the terminal as synchronized.

[0525] In this step, the headphones distinguish the first sound that has already been sent to the terminal from the first sound that has not been sent to the terminal (i.e., the first sound marked as pending synchronization). This facilitates the management of the sound in the headphones' memory, avoids repeatedly sending the same sound, and also saves on sound processing steps, improving efficiency. In some other embodiments, the sound acquisition method may not mark the first sound; that is, the sound acquisition method omits the process of marking the first sound as pending or synchronized. When connected to the terminal, the headphones can send part or all of the sound in their memory to the terminal in response to the transmission information received by the terminal.

[0526] In the above embodiments, the earphones transmit the first sound to the terminal when the charging case is open. In other embodiments, the earphones can also transmit the first sound to the terminal when the charging case is closed. In this case, after collecting the first sound, the earphones can reactivate Bluetooth or other wireless communication components, connect to the terminal, and then proceed with the subsequent transmission of the first sound. The earphones can increase their wireless communication power to compensate for the attenuation of the wireless signal caused by placing the earphones in the charging case, thus ensuring high reliability of wireless communication between the earphones and the terminal.

[0527] In some embodiments, the sound acquisition method may further include:

[0528] When a terminal is connected to headphones and the headphones are being worn, the terminal can send a playback command to the headphones, which then play the first sound stored in the headphones according to the playback command. When both headphones are being worn, both headphones can play; when only one headphone is being worn, only that headphone plays. The first sound stored in the headphones includes the first sounds stored in both headphones.

[0529] In this embodiment of the application, when the terminal is connected to the headphones, the user can be prompted to complete the operation process of the sound acquisition program, save the first sound, play back the first sound, add notes, etc. through the display content and prompts on the terminal interface, so as to make the auscultation process visible, reduce the operation threshold and improve ease of use.

[0530] The following describes some scenarios and display interfaces when the terminal executes the sound acquisition method in the communication system.

[0531] Please see Figures 33A to 33E , Figures 33A to 33E This is a schematic diagram of the display interface of the terminal provided in this application in some usage scenarios.

[0532] In some embodiments, such as Figure 33A As shown, when the terminal is connected to the headphones, the terminal's display interface 201 can display the storage box and headphones via a pop-up window 202, and / or display connection information, such as: headphones connected. Specifically, when the headphone assembly's storage box is opened and the headphones establish a connection with the terminal, the terminal can automatically pop up the aforementioned pop-up window.

[0533] In some embodiments, such as Figure 33B As shown, the terminal's display interface 201 may include a stethoscope icon 203. The user can start the terminal's stethoscope program by touching the stethoscope icon 203 and enter the stethoscope program's program interface.

[0534] In some embodiments, such as Figure 33C As shown, when the terminal enters the auscultation program, an earphone is placed inside the storage box, the storage box is closed, and the terminal receives a real-time auscultation confirmation operation. The terminal's display interface 201 can prompt the user to wear the earphone located outside the storage box via a pop-up window 204 or the program interface, and to place the storage box at the sound acquisition position. At this time, the user, following the terminal's prompts, can place the storage box containing the earphone at the sound acquisition position and wear the earphone outside the storage box. After the earphone inside the storage box acquires the first sound, it sends the first sound to the earphone outside the storage box and plays it, enabling the user to perform real-time auscultation. The pop-up window 204 or the program interface can also display prompts, such as "Ensure a proper fit to start recording; wearing the left earphone allows for auscultation," etc. In some other embodiments,

[0535] In some embodiments, such as Figure 33D As shown, when the terminal receives the first sound sent by the headphones, the terminal's display interface 201 can prompt that the first sound has been saved through the notification bar 205, pop-up window, or program interface, and provide a button or link that can be clicked to view the details of the data.

[0536] When the headphones send the first sound to the terminal, the terminal can provide a prompt through the display interface at the operating system level, such as through icons or pop-ups on the desktop. The terminal does not need to rely on a specific app, saving operation time and making the operation more convenient.

[0537] In some embodiments, such as Figure 33E As shown, when a user views the first sound, the display interface 201 can display the waveform 206 of the first sound, and the terminal can play the first sound synchronously. The display interface 201 may also include a first sound audio control button 207 and a text box 208 for adding notes, etc.

[0538] The above display interface is only a partial implementation method. In the same scenario, the terminal may have different display interfaces. This application embodiment does not strictly limit this.

[0539] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
