[0053] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0054] like Figure 1 As shown, the ear of the user may include physiological parts such as the helix, antihelix, concha, antitragus, earlobe, external auditory canal, tragus and antihelix fossa. Among them, further, the physiological parts such as the concha, helix fossa and antihelix have a certain volume and depth.

[0055] like Figure 2 As shown, an embodiment of the present invention provides an earphone, which includes a sound unit 1, an environment sensing unit, a main control unit 3, a clamping unit 4, a connecting arm 2 and a speaker unit, wherein the sound unit 1 is used to provide sound to the user, the main control unit 3 is electrically connected to the environment sensing unit, the sound unit 1 and the speaker 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 lower part of the ear, one end of the connecting arm 2 is connected to the main control unit 3 and / or the clamping unit 4, and the other end of the connecting arm 2 is connected to the sound unit 1, and the connecting arm 2 extends along the lower edge of the helix and bends upward to make the sound unit 1 close to the face or the ear.

[0056] like Figure 2 and Figure 3 As shown, the environment perception unit can be located on the sound unit 1 and / or the main control unit 3, and of course can also be located on the connecting arm 2. The environment perception unit is used to collect the first information of the target object, such as the user wearing the headset, and the first information includes acceleration and / or angular velocity; then, the main control unit 3 determines whether the first information collected by the environment perception unit meets the first preset condition. If the first preset condition is met, a first sound alarm instruction is sent to the sound unit 1 and / or a first emergency contact instruction is sent to the terminal device connected to the main control unit 3 for communication. The first sound alarm instruction is an instruction to control the sound unit 1 to issue a preset prompt voice, and the first emergency contact instruction is an instruction to dial a designated contact number pre-stored in the terminal device. The first preset condition is exceeding the acceleration preset value or the angular velocity preset value. In this embodiment, the environment perception unit includes a gyroscope 9 and / or an acceleration sensor (not shown).

[0057] For example, when the environment sensing unit includes an acceleration sensor, when the user falls, the acceleration sensor will produce a significant acceleration change. When the main control unit 3 determines that the acceleration exceeds the preset acceleration, the main control unit 3 sends a first alarm instruction to the sound unit 1. After receiving the first alarm instruction, the sound unit 1 will send a preset first prompt voice to show concern for the user. Alternatively, when the main control unit 3 determines that the acceleration exceeds the preset acceleration, the main control unit 3 will also send an emergency contact instruction to the terminal device (mobile phone) that is connected to the main control unit 3. At this time, when the terminal device receives the emergency contact instruction, the terminal device will dial the pre-stored designated contact number so that the designated contact can contact the user.

[0058] Alternatively, when the environmental sensing unit includes a gyroscope 9, when the user falls, the gyroscope 9 will produce an obvious change in angular velocity. When the main control unit 3 determines that the angular velocity exceeds the preset angular velocity, the main control unit 3 sends a first sound alarm instruction to the sound unit 1 and / or sends an emergency contact instruction to the terminal device that is communicatively connected to the main control unit 3.

[0059] More preferably, when the environment sensing unit is an acceleration sensor and a gyroscope 9, the gyroscope 9 is combined with the acceleration sensor data to improve the accuracy of fall detection. Due to the environment sensing unit, when the headset detects that the user has fallen, the first sound alarm instruction and / or the first emergency contact instruction are activated to buy precious rescue time for the faller, which is particularly important for people who are prone to falling, such as the elderly and children. When exercising outdoors or doing activities alone, this function of the headset can provide additional safety protection and reduce the risk of accidental injury that may be caused by falling.

[0060] In actual application, Figure 4 As shown, the environment sensing unit may also include a monitoring sensor 10, which is used to collect second information of the target object, the second information including the user's body temperature and / or the user's heart rate, and the main control unit 3 determines whether the second information collected by the environment sensing unit meets the second preset condition, and if the second preset condition is met, a second sound alarm instruction is issued to the sound unit 1. The second preset condition is that the user's body temperature or the user's heart rate exceeds the preset value, and the second sound alarm instruction is an instruction to control the sound unit 1 to issue a preset second prompt voice. The monitoring sensor 10 is a temperature sensor and / or a pulse sensor.

[0061] Since the back of the earlobe is close to the human aorta, the pulse sensor can detect the user's heart rate, and the temperature behind the earlobe is close to the human body temperature, the temperature sensor can detect the human body temperature. Among them, as for the specific position of the monitoring sensor 10, as long as the monitoring sensor 10 is located on the earphone, it can monitor the user's temperature and heart rate.

[0062] When the main control unit 3 determines that the user's body temperature or the user's heart rate exceeds a preset value, the main control unit 3 sends a second alarm instruction to the sound unit 1. After receiving the second alarm instruction, the sound unit 1 will send a preset second prompt voice to show concern for the user.

[0063] 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 ear clip 4, or the connecting arm 2. In this embodiment, Figure 5 As shown, the main microphone 5 is located on the side close to the user's mouth relative to the auxiliary microphone 8, the line connecting the user's mouth and the main microphone is the first line, the line connecting the main microphone 5 and the auxiliary microphone 8 is the second line, and the angle between the first line and the second line is e, where -60°≤e≤60°. It should be noted that the angle between the first line and the second line is based on the second line, when the first line is located above the second line, the angle is positive, and when the first line is located below the second line, the angle is negative.

[0064] 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 most clearly recognized, and the other directions are cleared to varying degrees. More preferably, the first line and the second line overlap. Since the two microphones are pointing 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 environmental 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 the present application can achieve the best sound pickup and noise reduction effect.

[0065] In order to achieve a better noise reduction effect, the distance between the main microphone 5 and the auxiliary microphone 8 should be satisfied, and the phases of the sounds emitted from the user's mouth reaching the main microphone 5 and the auxiliary microphone 8 are consistent. In the present application, beamforming signal processing technology is adopted. By adjusting the phase difference of the sound signals received by the main microphone 5 and the auxiliary microphone 8, the sound from the target direction is consistent in phase when received, and 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 delay-and-sum method, minimum variance distortion-free response (MVDR), etc. Beamforming algorithms are already existing technologies and will not be described in detail here.

[0066] like Figure 5 As shown, the main microphone 5 and the auxiliary microphone 8 can be both located on the sound unit 1, or as shown in FIG. Figure 8 As shown, the main microphone 5 is located on the connecting arm 2, and the auxiliary microphone 8 is located on the sound unit 1; or Figure 6 As shown, the main microphone 5 is located on the connecting arm 2, and the auxiliary microphone 8 is located on the main control unit 3; or as shown in Figure 7 As shown, the main microphone 5 and the auxiliary microphone 8 are both located on the main control unit 3. The settings of the main microphone 5 and the auxiliary microphone 8 only need to meet the requirements of the directional sound pickup technology and the beamforming signal processing technology.

[0067] In some embodiments, to reduce the size of the headset, the distance between the main microphone 5 and the auxiliary microphone 8 is G, 10mm≤G≤50mm. The distance between the user's mouth and the main microphone 5 is K, 70mm≤K≤130mm.

[0068] Since the clamping unit on the earphone can provide a mutual clamping force to clamp the ear on the side and / or the lower part of the ear, that is, the upper part away from the ear, and the connecting arm 2 extends along the lower edge of the helix and bends upward to make the sound unit close to the face or ear, the problem of overlapping and pressing the earphone with other devices when worn on the upper ear contour is solved, and the comfort of wearing with other devices at the same time is improved. The present invention provides a new earphone structure, which provides a reverse wearing method compared to the existing earphone, is more personalized and fashionable, and conforms to the trend of fashion.

[0069] Among them, the sound unit 1 can be a bone conduction speaker or a traditional air conduction speaker or other types of in-ear speakers. When the sound unit is an air conduction speaker or other types of in-ear speakers, the air conduction speaker or other types of in-ear speakers extend from the lower edge of the helix through the front or back of the earlobe and then bend upward to be close to the external auditory canal of the ear. In this embodiment, the sound unit 1 is preferably a bone conduction speaker. The bone conduction speaker extends from the lower edge of the helix through the front or back of the earlobe and then bends upward to be close to the user's face through the connecting arm 2, so that there is no interference with the inner part of the ear around the external auditory canal, and long-term use will not cause damage to the ear. It is preferred that the bone conduction speaker be close to the user's face with the outer edge close to the tragus to achieve a better bone conduction effect.

[0070] Bone conduction speakers transmit sound to the hearing system through bones, thereby producing hearing. Generally speaking, bone conduction speakers generate and transmit sound mainly through the following steps: Step 1, the bone conduction speaker obtains or generates a signal containing sound information, such as a current signal and / or a voltage signal carrying audio information; Step 2, the driving device in the bone conduction speaker generates vibration according to the signal; Step 3, the vibration is transmitted to the speaker housing through the transmission component.

[0071] Specifically, in step 1, the bone conduction speaker can obtain or generate a signal containing sound information in different ways. Sound information can refer to a video or audio file with a specific data format, or it can refer to data or files that can be carried in a general sense and eventually converted into sound through a specific path. The signal containing sound information can come from the storage unit of the bone conduction speaker itself, or it can come from an information generation, storage or transmission system other than the bone conduction speaker. The sound signal discussed here is not limited to electrical signals, but can also include other forms other than electrical signals, such as optical signals, magnetic signals, mechanical signals, etc. In principle, as long as the signal contains sound information that the speaker can use to generate vibrations, it can be processed as a sound signal. The sound signal is not limited to one signal source, but can come from multiple signal sources. These multiple signal sources can be related or unrelated to each other. The way of transmitting or generating the sound signal 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 by wire or wireless means, or it can directly obtain data from a storage medium to generate a sound signal. In some embodiments, a component with a sound collection function may be added to the bone conduction hearing aid, which can achieve a noise reduction effect by picking up the ambient background sound and processing the received sound signal.

[0072] In this embodiment, the sound unit 1 is separately arranged 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.

[0073] 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 mainly described by three elements: loudness, pitch and timbre. Loudness is the subjective feeling of the human ear to the strength of sound, which is proportional to the logarithmic value of the sound intensity. The greater the sound intensity, the louder it sounds. It is also related to the frequency and waveform of the sound. Tone, also known as pitch, refers to the subjective feeling of the human ear to the high and low frequency of sound vibration. Tone mainly depends on the fundamental frequency of the sound. The higher the fundamental frequency, the higher the pitch. At the same time, it is also related to the intensity of the sound. Timbre refers to the subjective feeling of the human ear to the characteristics of the sound. Timbre mainly depends on the spectral structure of the sound, and is also related to factors such as the loudness, duration, build-up process and decay process of the sound. The spectral structure of the sound is described by the fundamental frequency, the number of harmonic frequencies, the distribution of harmonic frequencies, the amplitude and the phase relationship. Different spectral structures have different timbres. Even if the fundamental frequency and loudness are the same, if the harmonic structure is different, the timbre will be different.

[0074] 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 ear helix, the helix fossa, the anti-helix and the anti-tragus, 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 all existing positions 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.

[0075] like Figure 17-Figure 22 As shown, the clamping unit 4 includes a first clamping portion 41 and a second clamping portion 42 which are arranged relatively 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 for clamping on the side of the ear and / or the lower part of the ear.

[0076] 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 Fig.19As shown, for ease of connection, it is preferably connected to the two opposite ends 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 clamping, hot pressing, riveting, bonding, or injection molding.

[0077] The first clamping portion 41 and the second clamping portion 42 each include at least one clamping member 4a, and the clamping members 4a in the first clamping portion 41 and the second clamping portion 42 both protrude outward in a direction away from the helix so as to form an accommodation space between the clamping members 4a of the first clamping portion 41 and the second clamping portion 42 for accommodating the outer edge of the helix. It should be noted that the number of the clamping members 4a in the first clamping portion 41 and the second clamping portion 42 may be the same or different. When the number of the clamping members 4a in the first clamping portion 41 and the second clamping portion 42 is different, the clamping members 4a in the first clamping portion 41 and the clamping members 4a in the second clamping portion 42 are staggered to increase the stability of clamping.

[0078] 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 one by one, and 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, and multiple pairs of clamping members 4a can be arranged, such as Figure 14-15 For two pairs of clamping members 4a, such as Figure 17-Figure 22 There are three pairs of clamping members 4a, and of course one pair or four or more pairs of clamping members 4a can be provided according to actual conditions.

[0079] like Fig.14 , Fig.15 , Figure 17-Figure 22 Preferably, the clamping unit 4 includes two or three pairs of clamping members 4a, and 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 one by one. It should be noted that when the extending distance of the set clamping members 4a is short, the clamping unit 4 is clamped on the side of the ear or the lower part of the ear, and when the extending distance of the set clamping members 4a is long, the clamping unit 4 can be clamped on the side of the ear and the lower part of the ear at the same time.

[0080] 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 portion 41 and the second clamping portion 42 are respectively connected 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 form openings relative to each other, and the second ends of the first clamping portion 41 and the second clamping portion 42 elastically clamp the side and / or lower part of the ear.

[0081] like Fig.10 As shown, each pair of clamping members 4a can relatively form an open circular arc structure, a U-shaped structure and a V-shaped structure, preferably an arc structure. When each pair of clamping members 4a is connected to the main control unit 3 to form an open circular ring structure, in order to make the clamping more stable, the opening angle of the clamping members 4a in the first clamping part 41 and the second clamping part 42 is F, 20°<F<50°, and when each pair of clamping members 4a corresponds to a non-circular ring structure, the spacing between the openings of the clamping members 4a in the first clamping part 41 and the second clamping part 42 is 2-5mm.

[0082] like Fig.11 As shown, in order to further ensure the stability of the side and / or lower part of the ear clamped by the clamping member 4a, the vertical distance H between the uppermost clamping member 4a and the lowermost clamping member 4a is 15mm-35mm, wherein the vertical distance specifically refers to the distance between the horizontal lines of the midpoints of the center lines of the uppermost clamping member 4a and the lowermost clamping member 4a, and in actual application, the vertical distances between two adjacent pairs of clamping members 4a can be set equidistantly or unequally as long as the stability of the clamping member 4a clamping the side and / or lower part of the ear can be ensured.
