Description
Technical Field
[0001] The present application relates to the technical field of audio device structures, and in particular to a wearable audio device. Background Art
[0002] Wearable audio devices such as headphones and earphones have been widely used in many aspects of life. With the continuous breakthroughs in electronic chip technology, the functions of headphones are increasing, and users' requirements for headphone sound quality are also getting higher and higher.
[0003] General headphone includes multiple components such as supporting wearing structure and earphone. The supporting wearing structure such as headband, ear hook, clip, etc. is used to fix the earphone on the user's head or ear; the earphone includes a cavity, which is divided into a front cavity and a rear cavity (back sound cavity), which is responsible for reflecting the airflow, acting on the diaphragm for a second time, increasing the volume, and mixing. Cavities of different materials will have different timbre effects. In order to improve the comfort of the headphone, human body fitting structures such as telescopic structures, elastic earmuffs, and sheaths are also provided to improve the wearing comfort and sound insulation effect. The earphone is also provided with a drive unit, such as an electroacoustic conversion device such as a speaker, which is the core component of the earphone and is responsible for converting electrical signals into sound; and a device connection part such as a plug, socket, circuit board, wire, etc., which is responsible for connecting the earphone to the audio source; in addition, there are other functional expansion accessories, such as sound control, microphone box, noise reduction box, etc., to provide additional functions.
[0004] In order to ensure the sound quality, existing headphones use connecting cables and plugs. The connecting cables are usually composed of wires and plugs, which affect the transmission of sound quality. However, the existing wiring headphone design has obvious defects. Among them, the use of traditional 3.5mm single-sided wiring will lead to fatal sound cavity leakage problems. Due to the presence of the jack, the structure of the headphone shell is destroyed, and the air inside the sound cavity cannot be effectively sealed, resulting in leakage of the sound propagation path, forming sound leakage, and affecting the clarity and fidelity of the sound.
[0005] In addition, the introduction of the 3.5mm terminal also brings great challenges to the design of the headphone sound cavity. Since the terminal occupies a certain space, there must be a large difference in the volume of the two sets of sound cavities, thus forming a different acoustic environment, which will lead to serious differences in the sound transmission characteristics of the left and right headphones, resulting in a large difference in the frequency band of the sound signal received by the user's two ears, ultimately resulting in inconsistent listening effects, lack of three-dimensional sense, and inability to truly enjoy a high-quality listening experience.

[0047] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thoroughly and comprehensively understood.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0050] See also Figure 1 and Figure 2 , an embodiment of the present application provides a wearable audio device 100, which is worn on the user's head and outputs audio to the user's ears for the output of audio signals. It can be understood that the wearable audio device 100 can be a headset, an earphone, or other structural types of headphones worn on a certain part of the user's body. The embodiment of the present application is illustrated by taking a headset as an example. The headset includes a connecting component 10 and an audio output component 20 respectively arranged at both ends of the connecting component 10, and the connecting component 10 is used to fix the audio output component 20 on the head and correspond to the position of the user's ear to provide audio to the user. The audio output component 20 described in this embodiment can be understood as a headset, and its working principle is based on electromagnetic induction and acoustic principles to convert electrical signals into sound.
[0051] Among them, the audio output component 20 is equipped with an audio driver unit, which is the core component of the headset. Common types include dynamic, capacitive and electric types. The dynamic driver unit consists of a magnet and a vibrating membrane. The current passes through the magnet to generate a magnetic field, causing the vibrating membrane to vibrate and produce sound. The audio output component 20 is connected to an external device through a connecting line 200. The connecting line 200 is usually composed of a wire and a plug, which affects the transmission of sound quality. Some high-quality headphones use high-purity copper wire or silver wire to improve the sound quality, and the plug usually uses a 3.5mm stereo plug to be compatible with various audio devices. Of course, the plug can also be 6.5mm, typeC, lighting and other specifications.
[0052] In order to prevent the sound of the external environment from interfering with the audio output of the audio output component 20, the headset can also be provided with sound insulation materials to reduce the interference of external noise and provide better sound quality and volume. The shell design of the audio output component 20 not only affects the aesthetic appearance, but also improves the sound quality and user comfort.
[0053] See also Figure 3 , Figure 3 : is a schematic diagram of a use state of the wearable audio device 100 provided in an embodiment of the present application. The figure only shows the wearable audio device 100 and the connecting line 200, and the plug part of the connecting line 200 is connected to the audio output component 20 of the wearable audio device 100; the external device is not shown, and can be an electronic device such as a computer, a tablet, a mobile phone, or other audio devices. The wearable audio device 100 provided in this embodiment is connected to the external device through the connecting line 200, thereby realizing the input and output of audio signals. In this embodiment, the connecting line 200 can not only input the audio signal of the external device, but also be provided with a microphone to receive the audio signal and transmit it to the wearable audio device 100 or the external device, thereby realizing the input of audio.
[0054] The main invention improvement of the wearable audio device 100 shown in the embodiment of the present application lies in the audio output component 20, which mainly improves the sound quality and the user's hearing effect by structural design of the shell 21. The audio output component 20 will be described in detail below for easy understanding.
[0055] Continue reading Figure 1 and Figure 2 The wearable audio device 100 includes a connection component 10 and an audio output component 20. The audio output component 20 is connected to the connection component 10 for outputting audio. Specifically, in this embodiment, there are two audio output components 20, which are disposed at both ends of the connection component 10 for outputting audio signals.
[0056] See also Figure 4 and Figure 5 The audio output component 20 includes a shell 21, a cover 22, a speaker 23, a mounting structure 24, and a wiring hole 25; the shell 21 has a accommodating cavity 21a and an opening 21b connected to the accommodating cavity 21a; the cover 22 covers the opening 21b to seal the accommodating cavity 21a; the cover 22 is provided with an opening 22a connected to the accommodating cavity 21a; the speaker 23 is arranged in the accommodating cavity 21a and is arranged close to the cover 22, and is arranged opposite to the opening 22a to transmit the audio to the outside; the mounting structure 24 is arranged in the accommodating cavity 21a and is connected to the shell 21, and the mounting structure 24 has an installation cavity 241a that is independent of the accommodating cavity 21a; the wiring hole 25 passes through the shell 21 and is connected to the installation cavity 241a, and is used for external equipment to pass through to connect to the wearable audio device 100.
[0057] Compared with the prior art, the wearable audio device 100 provided in the present application is provided with a sealed accommodating cavity 21a in the audio output component 20, and an independent installation cavity 241a is provided in the accommodating cavity 21a, and the wiring hole 25 is connected to the installation cavity 241a, so that when an external device is connected to the wearable audio device 100, the sealing of the accommodating cavity 21a can be ensured, so that when the accommodating cavity 21a is used as the back sound cavity 21c, it can ensure that the audio is propagated therein without leakage, avoiding the occurrence of sound leakage, thereby ensuring the clarity and fidelity of the sound quality.
[0058] In the example of the present application, the shape of the opening 21b of the shell 21 is a roughly circular design, and the shell 21 extends along the axial direction of the opening 21b to form a receiving cavity 21a. The shell 21 is viewed along the axial direction of the opening 21b, and the shell portion presents a roughly circular design. In other embodiments, the shape and structure of the shell 21 can be a square, rectangular, or elliptical design, etc., and can be adjusted according to the appearance and needs.
[0059] Specifically, in order to improve the wearing comfort of the user, the wearable audio device 100 further includes an earmuff assembly 30, which is arranged on the side of the cover body 22 away from the housing 21. The earmuff assembly 30 is partially used to protect the ears and head from the discomfort of long-term wearing, and the earmuff assembly 30 includes ear pads, which are usually made of soft materials such as artificial leather or sponge. At the same time, the connecting component 10 includes a connecting piece and a sheath, and the length of the connecting piece can be adjusted to adapt to different head sizes to improve the comfort of the user; the sheath is arranged on the outside of the connecting piece, and is made of soft materials such as artificial leather, sponge or silicone, etc., which is more comfortable to contact the user's head.
[0060] For further information, see Figure 6 , Figure 7 and Figure 8 The housing 21 includes a bottom wall 211 and a side wall 212 connected to the bottom wall 211, and the bottom wall 211 and the side wall 212 enclose the accommodating cavity 21a. The mounting structure 24 includes a side plate 241 and a sealing cover 242, the side plate 241 is arranged on the side of the bottom wall 211 facing the accommodating cavity 21a, and the sealing cover 242 is arranged on the end of the side plate 241 away from the bottom wall 211, and the side plate 241, the bottom wall 211, the side wall 212 and the sealing cover 242 enclose the mounting cavity 241a; the wiring hole 25 passes through the side wall 212 and communicates with the mounting cavity 241a.
[0061] Specifically, the side plate 241 divides the accommodating cavity 21a into two independent cavities, namely the installation cavity 241a and the back sound cavity 21c. With such a configuration, the installation cavity 241a can be connected to the wiring hole 25 and connected to external equipment; when the diaphragm of the speaker 23 vibrates, the back sound cavity 21c generates sound waves that radiate backwards and can vibrate and propagate in the back sound cavity 21c. Due to the sealed configuration of the back sound cavity 21c, and the wiring hole 25 is connected to the installation cavity 241a, the installation cavity 241a and the back sound cavity 21c are independent of each other and are not connected to each other, so that the air in the back sound cavity 21c is effectively sealed, avoiding leakage of the propagation path of the sound waves in the back sound cavity 21c, thereby avoiding the occurrence of sound leakage, and improving the clarity and fidelity of the sound; at the same time, the back sound cavity 21c can accommodate these backward sound waves, reduce mutual interference between sound waves, and further improve the sound quality.
[0062] In order to guide the sound in the back sound cavity 21c of the audio output component 20 and improve the sound quality, a mounting hole 22b is provided on the cover 22, and an auxiliary diaphragm 27 is provided in the mounting hole 22b. Specifically, the mounting holes 22b are provided on two opposite sides of the opening 22a, and the auxiliary diaphragm 27 is provided in each of the mounting holes 22b. When the speaker 23 outputs sound, the sound from the front of the speaker 23 is output to the outside through the opening 22a; the sound from the back of the speaker 23 propagates in the back sound cavity 21c, and after passing through the auxiliary diaphragm 27, the auxiliary diaphragm 27 vibrates, so as to transmit the sound in the back sound cavity 21c to the outside, and resonate or superimpose with the sound output to the outside through the opening 22a, thereby producing the final sound effect, so as to improve the sound quality. In addition, the setting of the auxiliary diaphragm 27 also guides the sound signal to the outside, avoids the vibration of the housing 21 caused by the repeated propagation of the sound in the back sound cavity 21c, and improves the user experience. In this embodiment, the earmuff assembly 30 is disposed on a side of the cover body 22 away from the housing 21 , and covers the mounting hole 22 b and the auxiliary diaphragm 27 .
[0063] In order to ensure that the frequency bands of the sound signals received by the user's two ears are basically the same or have little difference, so that the hearing effect is consistent and a high-quality listening experience is enjoyed, in the embodiment of the present application, the two audio output components 20 can adopt the same structural design, that is, the accommodating cavity 21a and the installation cavity 241a are designed at the same position, and the installation structure 24 of the same size is adopted, so that the remaining space in the accommodating cavity 21a is the same, that is, the space and layout design of the back sound cavity 21c are the same, so as to achieve the same acoustic field of the back sound cavity 21c of the two audio output components 20. It can be understood that the use of two audio output components 20 with the same structure can also improve production efficiency and assembly efficiency, so that the production cost of the product is reduced.
[0064] In this embodiment, the audio output component 20 also includes a connection terminal 26 disposed in the mounting cavity 241a and arranged opposite to the wiring hole 25, the connection terminal 26 is used to connect the external device, and the connection terminal 26 is electrically connected to the speaker 23. The connection terminal 26 is used to connect different types of connection wires 200, specifically, connection wires 200 connected to different types of plugs, and the plug can be any one of 3.5mm, 6.5mm, typeC, and lighting. Therefore, the types of the connection terminals 26 are also different, resulting in different sizes of the connection terminals 26, such as some connection terminals 26 are relatively small in size, and some connection terminals 26 are relatively large in size. In the embodiment of the present application, the volume size of the installation cavity 241a is designed to accommodate various types of connection terminals 26, thereby ensuring that the volume size of the installation cavity 241a is consistent, that is, the side panel 241 is connected to the shell 21 at the same position in the accommodating cavity 21a, and the volume size of the accommodating cavity 21a in the shell 21 remains unchanged. When the volume size of the installation cavity 241a is determined, the space occupancy of the installation cavity 241a relative to the accommodating cavity 21a can be the same, and the structural design of other parts in the accommodating cavity 21a is the same, thereby ensuring that the space size and structural layout design of the back sound cavity 21c are the same, that is, the shape and structure of the back sound cavity 21c are the same, thereby ensuring that the acoustic fields of any two back sound cavities 21c of the audio output components 20 produced are consistent, ensuring that the two audio output components 20 in the wearable audio device 100 output audio that is basically the same or has little difference in sound transmission characteristics, so that the frequency bands of the sound signals received by the user's two ears are the same or have little difference, so that the listening effect is consistent. In other embodiments, the audio output component 20 further includes a battery, and the wiring terminal can be used to connect the battery, and the battery is charged by connecting the wiring terminal through an external connection line 200, and the connection line 200 is connected to the connection terminal 26 through the wiring hole 25. In other embodiments, the wiring terminal may not be provided, and other connection methods or charging methods may be adopted. It is only necessary to provide the relevant structure in the installation cavity 241a, and to achieve sealing and isolation with the back sound cavity 21c outside the installation cavity 241a, which can also achieve the role in the embodiment of the present application and improve the sound quality.
[0065] Since the types of the connecting terminals 26 are different, their sizes are also different. In order to ensure that the connecting terminal 26 is firmly installed in the installation cavity 241a and avoid shaking and other faults such as poor contact or noise, the installation structure 24 also includes a limiting unit 243 arranged in the installation cavity 241a, which is used to limit the connecting terminal 26.
[0066] In this embodiment, the connection terminal 26 is of a relatively small type, and the description will continue by taking the connection terminal 26 connected to a connection line 200 adapted to a 3.5 mm plug type as an example.
[0067] Continue reading Figure 8 The limiting unit 243 includes a limiting seat 2431 disposed adjacent to the wiring hole 25, the limiting seat 2431 is disposed in the mounting cavity 241a and connected to the side wall 212, and one end of the connection terminal 26 close to the wiring hole 25 is disposed in the limiting seat 2431. A limiting groove 2433 is disposed on the limiting seat 2431, and the limiting groove 2433 abuts against the connection terminal 26. In this embodiment, the limiting groove 2433 is disposed close to the wiring hole 25, and is used to closely abut against one end of the connection terminal 26 close to the wiring hole 25. Specifically, the shape of the limiting groove 2433 matches the shape of one end of the connection terminal 26 close to the wiring hole 25, and is used to abut against one end of the connection terminal 26 close to the wiring hole 25. In this embodiment, the end of the connection terminal 26 close to the wiring hole 25 is cylindrical, and the limiting groove 2433 is designed in a semicircular structure, so that the cylindrical end of the connection terminal 26 can be abutted and limited.
[0068] In order to ensure the sealing of the installation cavity 241a and improve the installation stability of the connection terminal 26, the installation structure 24 also includes a sealing member 245; the limit seat 2431 is provided with a clamping groove 2434, the clamping groove 2434 is arranged between the limit groove 2433 and the wiring hole 25, and the sealing member 245 is arranged in the clamping groove 2434 and abuts the connection terminal 26 and the side wall 212. Specifically, the sealing member 245 is made of silicone material or other materials with certain elasticity or flexibility, and can be completely clamped in the clamping groove 2434. And one side of the sealing member 245 abuts the connection terminal 26, so that it can be better sealed and prevented from loosening. Therefore, when the sealing cover 242 covers the end of the side plate 241 away from the bottom wall 211, the sealing cover 242 abuts the sealing member 245, and the sealing member 245 can thus be pressed against one end of the connection terminal 26, thereby ensuring the installation stability of the connection terminal 26. Such an arrangement can ensure that the end of the connecting terminal 26 close to the wiring hole 25 can be tightly abutted against the limiting seat 2431 to ensure stable installation.
[0069] In order to further limit the connection terminal 26, the limiting unit 243 includes a limiting block 2432, which is disposed on the bottom wall 211 and abuts against an end of the connection terminal 26 away from the wiring hole 25. Figure 7As shown, the limit block 2432 is arranged in the middle position of the installation cavity 241a, and abuts against the two ends of the connection terminal 26 together with the limit seat 2431, thereby stably fixing the connection terminal 26 and ensuring that the connection terminal 26 is tightly connected with the limit block 2432 and the limit seat 2431 to prevent it from shaking.
[0070] Continue reading Figure 6 , Figure 7 , a step portion 2411 is provided at one end of the side plate 241 away from the bottom wall 211, and a side surface of the sealing cover 242 facing the bottom wall 211 abuts against the step portion 2411; specifically, the thickness of the sealing cover 242 is consistent with the height of the step portion 2411, that is, a side surface of the sealing cover 242 away from the bottom wall 211 and a side surface of the side plate 241 away from the bottom wall 211 are located in the same plane. Such a configuration can ensure that the sealing cover 242 can completely cover the installation cavity 241a to achieve sealing of the installation cavity 241a, and also ensure that the installation cavity 241a and the accommodating cavity 21a are independent of each other and do not affect each other, thereby ensuring that the accommodating cavity 21a can be sealed and no sound is leaked, thereby improving the sound quality.
[0071] In this embodiment, the sealing cover 242 is a printed circuit board, which can save space and achieve reasonable utilization of space layout. At the same time, the printed circuit board is also provided with a plurality of make way grooves (not shown in the figure) for avoiding the pins of the connection terminal 26. The pins of the connection terminal 26 can be electrically connected to the speaker 23 through the lead wire, thereby ensuring that the external device can be electrically connected to the audio output component 20, so as to input or output audio signals.
[0072] In order to further ensure the connection stability between the sealing cover 242 and the side plate 241, the mounting structure 24 also includes a connecting column 244 disposed in the mounting cavity 241a. Specifically, the connecting column 244 is disposed adjacent to the side plate 241, the connecting column 244 is connected to the sealing cover 242, and the height of the connecting column 244 is consistent with the height of the step portion 2411. Such a design can ensure that the sealing cover 242 can match and fit each other when covering the step portion 2411, thereby improving the connection stability. In this embodiment, a threaded hole 2441 is provided on the connecting column 244, and a through hole 2421 is provided on the sealing cover 242 corresponding to the position of the connecting column 244, the through hole 2421 is butted with the threaded hole 2441, and the sealing cover 242 is connected to the connecting column 244 by screws, thereby improving the connection stability of the sealing cover 242.
[0073] Specifically, the number of the connecting posts 244 is 3, and the 3 connecting posts 244 are distributed in triangular points. In this embodiment, the installation cavity 241a formed by the side plate 241 and the shell 21 is roughly in the shape of a cube, that is, the side plate 241 and the shell 21 are enclosed to form a rectangular parallelepiped shape, wherein the short side of the side plate 241 is arranged opposite to the part of the shell 21 where the wiring hole 25 is located, and the two long sides of the side plate 241 are arranged opposite to each other and connect the short side and the shell 21. The three connecting posts 244 are respectively arranged on the two long sides and the short side to form triangular points, so that the sealing cover 242 can be stably supported. In other embodiments, the cross-section of the installation cavity 241a formed by the side plate 241 can be square, circular or elliptical, as long as the components installed therein can be sealed and kept independent of the accommodating cavity 21a.
[0074] Figures 4 to 8 shows a structure of an audio output component 20, Figures 9 to 13 The structure of another audio output component 20 is shown. The two audio output components 20 are respectively arranged at opposite ends of the connecting component 10 to provide audio for the user.
[0075] in, Figures 9 to 13 The structure of the audio output assembly 20 is shown Figures 4 to 8 The structure of the audio output component 20 shown is roughly the same, the difference is that the size of the connecting terminal 26 arranged in the installation cavity 241a is different. In order to adapt to the larger connecting terminal 26, the limiting unit 243 in the installation cavity 241a is adjusted to limit the connecting terminal 26 to ensure the stability of the connecting terminal 26.
[0076] The following will Figures 9 to 13 The different structural parts of the illustrated audio output assembly 20 are described in detail.
[0077] exist Figures 9 to 13 In the illustrated audio output assembly 20 , the connection terminal 26 is of a relatively large type, and the description will be continued by taking the connection terminal 26 connected to a connection line 200 adapted to a 6 mm plug type as an example.
[0078] In this embodiment, the limiting unit 243 includes a limiting seat 2431 and a limiting block 2432. The limiting seat 2431 is arranged near the wiring hole 25. The limiting seat 2431 is arranged in the installation cavity 241a and connected to the side wall 212. The end of the connection terminal 26 close to the wiring hole 25 is arranged in the limiting seat 2431. Specifically, the end of the connection terminal 26 close to the wiring hole 25 abuts the side wall 212. In some embodiments, the end of the connection terminal 26 close to the wiring hole 25 can partially penetrate into the wiring hole 25 and abut the hole wall of the wiring hole 25 to ensure installation stability. In this embodiment, there is no need to set a sealing member 245. When the sealing cover 242 is covered on the step portion 2411, it can directly abut the connected terminal 26, so as to stably fix the connection terminal 26 in the installation cavity 241a together with the bottom wall 211, the limiting seat 2431 and the limiting block 2432.
[0079] The limit block 2432 is disposed at a position of the side plate 241 away from the wiring hole 25 , and abuts against two ends of the connection terminal 26 with the limit seat 2431 to limit the connection terminal 26 . Specifically, the limit block 2432 is disposed on the connection column 244 disposed opposite to the wiring hole 25 .
[0080] In the above-mentioned embodiment, two different sizes or types of connection terminals 26 are shown. Of course, in other embodiments, the connection terminal 26 can also be connected to a connection line 200 adapted to a type C or lighting plug. In this embodiment, the size of the installation cavity 241a can completely accommodate the connection terminal 26, and is arranged corresponding to the wiring hole 25, so as to be isolated from the accommodating cavity 21a, forming two independent cavities, thereby ensuring the sealing of the back sound cavity 21c, avoiding the occurrence of sound leakage, and thus improving the clarity and fidelity of the sound.
[0081] In the embodiment of the present application, two audio output components 20 with substantially the same structure are shown, which are connected at opposite ends of the connection component 10 to output audio for the left and right ears of the user. Since the difference between the audio output components 20 lies in the subtle difference in the structure inside the installation cavity 241a, the volume size and proportion of the accommodating cavity 21a and the installation cavity 241a are consistent, so that the shape structure of the back sound cavity 21c and the proportion of the back sound cavity 21c in the accommodating cavity 21a are consistent, so that the acoustic field of the back sound cavity 21c in the audio output components 20 of the left and right ears is consistent, which effectively improves the sound quality while ensuring that the difference in the sound transmission characteristics output by the audio output components 20 of the left and right ears is small or no difference, so that there is a small segment difference or no segment difference in the frequency band of the sound signal received by the user's two ears, so that the left and right ears have the same hearing effect and have a three-dimensional sense.
