[0041] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0042] like Figure 1 As shown, the user's ear may include physiological parts such as the helix, antihelix, concha, antitragus, earlobe, external auditory canal, tragus, and antihelix fossa. Furthermore, the concha, helix fossa, and antihelix physiological parts have a certain volume and depth.

[0043] like Figure 2 As shown, an embodiment of the present invention provides an earphone, which includes a sound-emitting unit 1, an environmental sensing unit, a main control unit 3, a clamping unit 4, a connecting arm 2 and a transmitter unit, wherein the sound-emitting unit 1 is used to provide sound to the user, the main control unit 3 is electrically connected to the environmental sensing unit, the sound-emitting unit 1 and the transmitter unit, respectively, the clamping unit 4 is arranged on the main control unit 3, and provides a clamping force to clamp on the side of the ear and / or the bottom of the ear, one end of the connecting arm 2 is detachably connected to the main control unit 3 and the connecting arm 2 and the main control unit 3 are coaxially rotatable, the other end of the connecting arm 2 is connected to the sound-emitting unit 1, and the connecting arm 2 extends along the lower edge of the helix and bends upward to make the sound-emitting unit 1 close to the face or ear.

[0044] like Figure 2-Figure 4 As shown, the environment sensing unit can be located on the sound unit 1 and / or the main control unit 3, or can also be located on the connecting arm 2. The environment sensing unit is used to collect the acceleration and / or angular velocity of a user object, such as a user wearing the headset. In this embodiment, the environment sensing unit includes a gyroscope 9 and / or an acceleration sensor (not shown).

[0045] The environmental sensing unit includes an accelerometer, which generates a significant change in acceleration when a user falls. Alternatively, the environmental sensing unit includes a gyroscope 9, which generates a significant change in angular velocity when a user falls. More preferably, the environmental sensing unit includes both the accelerometer and the gyroscope 9, and the gyroscope 9 combines data from the accelerometer to improve the accuracy of fall detection.

[0046] In actual application, Figure 4 As shown, the environment sensing unit may further include a monitoring sensor 10, which is used to collect the user's body temperature and / or the user's heart rate, wherein the monitoring sensor 10 is a temperature sensor and / or a pulse sensor.

[0047] Since the back of the earlobe is close to the human aorta, the pulse sensor can be used to detect the user's heart rate. The temperature behind the earlobe is close to the body temperature, so the temperature sensor can be used to detect the body temperature. Regarding the specific location of the monitoring sensor 10, as long as the monitoring sensor 10 is located on the earphone and can monitor the user's temperature and heart rate, it is sufficient.

[0048] In this embodiment, the main control unit 3 can process acceleration, angular velocity, body temperature, and heart rate. It should be noted that the earphones in this embodiment are physical components. This embodiment does not involve improvements to computer programs; its primary contribution to the prior art lies in the connections and structural relationships between the various components or hardware structures within the earphones.

[0049] The voice transmission unit includes a main microphone 5 and a secondary microphone 8, wherein the main microphone (close to the user's mouth) is responsible for capturing the user's voice signal, while the secondary microphone (far away from the user's mouth) is responsible for capturing the surrounding environmental noise. The main microphone 5 and the secondary microphone 8 can be located on any one or both of the sound unit 1, the main control unit 3, the clamping unit 4, or the connecting arm 2. In this embodiment, Figure 6 As shown, the primary microphone 5 is located closer to the user's mouth than the secondary microphone 8. The line connecting the user's mouth and the primary microphone is a first line, and the line connecting the primary microphone 5 and the secondary microphone 8 is a second line. The angle between the first and second lines is e, where -60° ≤ e ≤ 60°. It should be noted that the angle between the first and second lines is based on the second line. When the first line is above the second line, the angle is positive, and when the first line is below the second line, the angle is negative.

[0050] Since the voice transmission unit includes two microphones, and the microphones have directional sound pickup, when the angle between the first line and the second line is between ±60°, the user's voice can be recognized most clearly, and the rest of the directions are cleared to varying degrees. More preferably, the first line and the second line overlap. Since both microphones point in the same direction, that is, toward the user's mouth, the sound from other directions will be relatively attenuated due to the distance and direction. In this way, the impact of ambient noise and other interfering sounds will be significantly reduced. And by controlling the angle between the first line and the second line within ±60°, it is more sensitive to the sound from the direction of the user's mouth, and less sensitive to the sound from other directions. Therefore, the specific setting of the dual microphones in this application can achieve the best sound pickup and noise reduction effects.

[0051] In order to achieve a better noise reduction effect, the distance between the main microphone 5 and the secondary microphone 8 should be sufficient so that the phases of the sounds emitted from the user's mouth are consistent when they reach the main microphone 5 and the secondary microphone 8 respectively. In this application, beamforming signal processing technology is adopted. By adjusting the phase difference of the sound signals received by the main microphone 5 and the secondary microphone 8, the sounds from the target direction are consistent in phase when received, while the sounds from other directions cancel each other out due to the phase difference. Two microphone arrays are used to enhance the sound signal in the direction of the user's mouth while suppressing noise from other directions. Common beamforming algorithms include the Delay-and-Sum method, the Minimum Variance Distortionless Response (MVDR), etc. The beamforming algorithm is already a prior art and will not be described in detail here.

[0052] like Figure 6 As shown, preferably, the main microphone 5 and the auxiliary microphone 8 can be both located on the sound unit 1, or as shown in FIG. Figure 7-8 As shown, the main microphone 5 is located on the connecting arm 2, and the secondary microphone 8 is located on the sound-emitting unit 1; or the main microphone 5 is located on the connecting arm 2, and the secondary microphone 8 is located on the main control unit 3 (not shown); or the main microphone 5 and the secondary microphone 8 are both located on the main control unit 3 (not shown). It can be understood that the settings of the main microphone 5 and the secondary microphone 8 only need to meet the requirements of directional sound pickup technology and beamforming signal processing technology.

[0053] In some embodiments, to reduce the size of the headset, the distance between the main microphone 5 and the secondary microphone 8 is G, 10mm≤G≤50mm. The distance between the user's mouth and the main microphone 5 is K, 70mm≤K≤130mm.

[0054] Because the clamping unit on the earphone can provide a reciprocal clamping force to clamp the earphone to the side and / or lower part of the ear, i.e., away from the upper part of the ear, and the connecting arm 2 extends along the lower edge of the helix and bends upward to place the sound unit against the face or ear, the problem of overlapping and compressing the earphone with other devices when worn on the upper ear contour is solved, and the comfort of wearing with other devices is improved. The utility model provides a brand-new earphone structure, which provides a reverse wearing method compared to existing earphones, is more personalized and fashionable, and conforms to the trend of fashion.

[0055] The sound-emitting unit 1 can be a bone conduction speaker or a traditional air conduction speaker or other type of in-ear speaker. When the sound-emitting unit is an air conduction speaker or other type of in-ear speaker, the air conduction speaker or other type of in-ear speaker extends from the lower edge of the helix, passes in front of or behind the earlobe, then bends upward and rests against the external auditory canal of the ear. In this embodiment, the sound-emitting unit 1 is preferably a bone conduction speaker. The bone conduction speaker extends from the lower edge of the helix, passes in front of or behind the earlobe, then bends upward and rests against the user's face. This ensures that the bone conduction speaker does not interfere with the inner ear around the external auditory canal, and long-term use will not cause damage to the ear. Preferably, the bone conduction speaker rests against the user's face, with its outer edge close to the tragus, to achieve a better bone conduction effect.

[0056] Bone conduction speakers transmit sound through the bones to the auditory system, thereby producing hearing. Generally speaking, bone conduction speakers generate and transmit sound through the following steps: Step 1: The bone conduction speaker acquires or generates a signal containing sound information, such as a current signal and / or voltage signal carrying audio information; Step 2: The driver in the bone conduction speaker vibrates in response to the signal; Step 3: The vibration is transmitted to the speaker housing via a transmission assembly.

[0057] Specifically, in step 1, the bone conduction speaker can acquire or generate a signal containing sound information in various ways. Sound information can refer to video or audio files in a specific data format, or it can generally refer to data or files that can ultimately be converted into sound through a specific method. The signal containing sound information can originate from the bone conduction speaker's own storage unit, or from an information generation, storage, or transmission system external to the bone conduction speaker. The sound signals discussed here are not limited to electrical signals and may also include other forms besides electrical signals, such as optical, magnetic, and mechanical signals. In principle, any signal containing sound information that can be used by the speaker to generate vibrations can be processed as a sound signal. Sound signals are not limited to a single signal source and can originate from multiple signal sources. These multiple signal sources can be related or independent. The sound signal transmission or generation method can be wired or wireless, and can be real-time or delayed. For example, the bone conduction speaker can receive an electrical signal containing sound information via wired or wireless means, or it can directly acquire data from a storage medium to generate the sound signal. In some embodiments, a component with a sound collection function may be added to the bone conduction hearing aid to achieve a noise reduction effect by picking up the ambient background sound and processing the received sound signal.

[0058] In this embodiment, the sound unit 1 is separately provided from the main control unit 3. The main control unit 3 is provided with control components such as a battery and a circuit board. The battery and the speaker in the sound unit 1 can be relatively large to meet the requirements of longer battery life and high-quality sound quality.

[0059] The term "sound quality" used here can be understood as reflecting the quality of sound, referring to the fidelity of audio after processing, transmission, and other processes. Sound quality is primarily described by three elements: loudness, pitch, and timbre. Loudness is the subjective perception of sound intensity by the human ear. It is proportional to the logarithm of sound intensity; higher intensity sounds appear louder. It is also related to the frequency and waveform of the sound. Pitch, also known as pitch, refers to the subjective perception of the frequency of sound vibrations by the human ear. Pitch is primarily determined by the fundamental frequency of the sound; higher fundamental frequencies indicate higher pitch. It is also related to the intensity of the sound. Timbre refers to the subjective perception of the distinctive characteristics of the sound by the human ear. Timbre is primarily determined by the spectral structure of the sound, as well as factors such as loudness, duration, buildup, and decay. The spectral structure of a sound is described by the fundamental frequency, the number of harmonics, the distribution of harmonics, amplitude, and phase relationships. Different spectral structures correspond to different timbre. Even with the same fundamental frequency and loudness, different harmonic structures will result in different timbre.

[0060] In the present application, the main body of the earphone is clamped on the side of the ear and / or the lower part of the ear by the clamping unit 4 to avoid the upper part of the ear, that is, to avoid the position of the upper edge of the helix, thereby solving the problem of overlap and compression between the earphone and other devices when worn on the upper ear contour, and improving the comfort of wearing with other devices at the same time. Among them, the side of the ear can be the side of the helix, the helix fossa, the antihelix and the antitragus, and the lower part of the ear can be the position of the earlobe. In the present application, the clamping unit 4 can be clamped on the side of the ear and / or the lower part of the ear, and any existing position that can be clamped on the ear except the position above the helix can be clamped, as long as the earphone can be prevented from falling. Whether the clamping unit 4 is clamped on the side of the ear or the lower part of the ear, or clamps the side of the ear and the lower part of the ear at the same time is determined by the shape of the clamping unit.

[0061] like Figure 9 and Figure 10 As shown, one end of the connecting arm is detachably connected to the main control unit, which facilitates the production of the earphones, makes production more optimized and maintenance more convenient. At the same time, since one end of the connecting arm is coaxially rotated with the main control unit, the axial direction still maintains a certain degree of freedom, and the earpiece connected to the connecting arm can be easily adjusted to fit the cheek, thereby enhancing the wearing experience of the earphones.

[0062] like Figure 9 As shown, the connecting arm 2 and the main control unit 3 are plugged together, and a protrusion can be set on the connecting arm 2, and a corresponding clamping groove can be set on the main control unit 3; or a clamping groove can be set on the connecting arm 2, and a corresponding protrusion can be set on the main control unit 3. Figure 10 As shown, the connecting arm 2 and the main control unit 3 are also connected by magnetic attraction.

[0063] like Figure 8 As shown, in order to increase the stability of the connection of the connecting arm 2, the connecting arm 2 can also be plugged or magnetically connected to the clamping unit 4 at the same time.

[0064] like Figure 5 As shown, the clamping unit 4 includes a first clamping portion 41 and a second clamping portion 42 that are arranged relative to each other to cooperate in providing a clamping force. The first ends of the first clamping portion 41 and the second clamping portion 42 are both connected to the main control unit 3, and the second ends of the first clamping portion 41 and the second clamping portion 42 are arranged facing each other and cooperate with each other to provide an interactive clamping force to clamp on the side of the ear and / or the lower part of the ear.

[0065] The first end of the first clamping portion 41 and the first end of the second clamping portion 42 can be connected to the same side of the main control unit 3 at the same time, or can be connected to two opposite ends of the main control unit 3, such as Figure 5 As shown, for ease of connection, it is preferably connected to the opposite end surfaces of the main control unit 3. The connection between the first clamping portion 41 and the second clamping portion 42 and the main control unit 3 can be a fixed or movable connection method such as clamping, hot pressing, riveting, bonding, plugging, magnetic attraction or injection molding.

[0066] Each of the first and second clamping portions 41, 42 includes at least one clamping member 4a. The clamping members 4a in each of the first and second clamping portions 41, 42 protrude outwardly, away from the helix, creating a space between the clamping members 4a for accommodating the outer edge of the helix. It should be noted that the number of clamping members 4a in the first and second clamping portions 41, 42 can be the same or different. When the number of clamping members 4a in the first and second clamping portions 41, 42 is different, the clamping members 4a in the first and second clamping portions 41, 42 are staggered to enhance clamping stability.

[0067] When the number of clamps in the first clamping portion 41 and the second clamping portion 42 is the same, the clamping members 4a in the first clamping portion 41 and the clamping members 4a in the second clamping portion 42 are arranged in a one-to-one correspondence. Each corresponding two clamping members 4a in the first clamping portion 41 and the second clamping portion 42 can be called a pair of clamping members 4a. In order to achieve clamping balance, the spacing in each pair of clamping members 4a can be changed. Multiple pairs of clamping members 4a can be provided, such as Figure 2-Figure 5 For two pairs of clamping members 4a, such as Figure 7-Figure 8 There are three pairs of clamping members 4a, and of course one pair, two pairs, or four or more pairs of clamping members 4a can be provided according to actual conditions.

[0068] like Figure 2-Figure 8Preferably, the clamping unit 4 includes two or three pairs of clamping members 4a. The clamping members 4a in the first clamping portion 41 and the second clamping portion 42 are arranged along the extension direction of the main control unit 3, and the clamping members 4a of the first clamping portion 41 and the clamping members 4a of the second clamping portion 42 are arranged in a one-to-one correspondence. It should be noted that when the clamping members 4a extend a short distance, the clamping unit 4 clamps to the side of the ear or the lower part of the ear. When the clamping members 4a extend a long distance, the clamping unit 4 can clamp to both the side of the ear and the lower part of the ear.

[0069] Preferably, the clamping member 4a is made of elastic material, and can be clamped to the side and / or lower part of the ear through the elastic opening and closing angle of the clamping unit 4. The first ends of the clamping member 4a of the first clamping part 41 and the second clamping part 42 are respectively connected to the two opposite end surfaces of the main control unit 3, and the second ends of the first clamping part 41 and the second clamping part 42 form openings relative to each other, and the second ends of the first clamping part 41 and the second clamping part 42 elastically clamp the side and / or lower part of the ear.

[0070] like Figure 3 As shown, each pair of clamping members 4a can form an open arc-shaped structure, a U-shaped structure, or a V-shaped structure (not shown), preferably an arc-shaped structure. In actual use, the vertical distance between two adjacent pairs of clamping members 4a can be equal or unequal as long as the clamping members 4a can ensure stability in clamping the side and / or lower part of the ear.

[0071] Of course, the clamping member 4a can also be made of hard plastic material. The first ends of the clamping member 4a of the first clamping portion 41 and the second clamping portion 42 are respectively hinged to the two opposite end surfaces of the main control unit 3, and the second ends of the first clamping portion 41 and the second clamping portion 42 are relatively arranged to cooperate in clamping the side and / or lower part of the ear.

[0072] like Figure 7 As shown, in some embodiments, the connecting arm 2 can be an elastic material of an integrated structure, wherein the first end of the connecting arm 2 is connected to the sound unit 1, and the second end of the connecting arm 2 is detachably connected to the main control unit 3, as shown in FIG. Figure 8 As shown, depending on the specific shape of the connecting arm 2, the second end of the connecting arm 2 can also be connected to both the main control unit 3 and the clamping unit 4. The elastic material refers to a shape memory alloy, an intelligent material that can restore its original shape under certain conditions. Preferably, it comprises a metal wire 6 and a soft rubber disposed on the outside of the metal wire 6. The metal wire 6 is wrapped around the outside of the audio cable 7, thereby improving wearing comfort and allowing it to return to its original state even after being stretched or twisted by a large force. Furthermore, the light weight of the connecting arm 2 further enhances comfort.

[0073] like Figure 3As shown, in other embodiments, the connecting arm 2 is a hard plastic part and will not deform when worn. The connecting arm 2 includes a first connecting arm and a second connecting arm. The first end of the first connecting arm is connected to the sound unit 1, and the second end of the first connecting arm is hinged to the first end of the second connecting arm. The second end of the second connecting arm is detachably connected to the main control unit 3. Of course, the second end of the second connecting arm can also be detachably connected to the main control unit 3 and the clamping unit 4 at the same time. The specific connection situation can be determined according to the specific shape of the connecting arm 2.
