[0043] To better explain the present utility model for easier understanding, the present utility model will be described in detail below in conjunction with the accompanying drawings through specific implementation manners.

[0044] As Figure 1 shown, the user's ear can include physiological parts such as the helix, antihelix, concha, antitragus, lobule, external auditory canal, tragus, and fossa of the antihelix, etc. Among them, further, physiological parts such as the concha, fossa of the helix, and antihelix have a certain volume and depth.

[0045] As Figure 2 shown, an embodiment of the present utility model provides a pair of headphones, which includes a sound generating part 1, a main control unit 3, an ear clip 4, and a connecting arm 2. Among them, the sound generating part 1 is used to provide sound to the user. The main control unit 3 is electrically connected to the sound generating part 1. The ear clip 4 is arranged on the main control unit 3 to provide a clamping force to clamp on the side and / or lower part of the ear. The first end of the connecting arm 2 is connected to the main control unit 3 and / or the ear clip 4, and the second end of the connecting arm 2 is connected to the sound generating part 1. The connecting arm 2 is an arc-shaped structure bent upward so that the sound generating part 1 abuts against the face or the ear. Preferably, the connecting arm 2 is an arc-shaped structure extending along the lower edge of the helix and bent upward. To ensure high-quality sound, when the ear clip 4 clamps on the side and / or lower part of the ear during headphone wearing, the sound generating part 1 is located within area A. Area A is a circular area, and the center of area A is located on the user's face and on the extension line of the horizontal line passing through the upper and lower centers of the tragus.

[0046] As Figure 5 shown, preferably, the distance E between the center of area A and the center of the tragus is 10 - 15 mm, specifically, the distance E is 10 mm, and the diameter D of area A is 50 - 60 mm. Preferably, the diameter is 50 mm.

[0047] Since the ear clip 4 on the headphones can provide an interacting clamping force to clamp on the side and / or lower part of the ear, that is, away from the upper part of the ear, and at the same time, in cooperation with the connecting arm 2 being an arc-shaped structure bent upward so that the sound generating part abuts against the face or the ear, it solves the problem of overlap and compression when the headphones are worn on the upper ear contour with other devices, and improves the comfort of wearing and using with other devices simultaneously. The present utility model provides a brand-new headphone structure. Compared with the existing headphones, it provides a reverse wearing method, which is more personalized and fashionable, and conforms to the trend of the times.

[0048] Among them, the sound generating part 1 can be a bone conduction speaker or a traditional air conduction speaker. When the sound generating part 1 is an air conduction speaker, the air conduction speaker extends along the lower edge of the helix through the front or back of the earlobe and then bends upward to abut against the external auditory canal of the ear through the connecting arm 2. In this embodiment, it is preferred that the sound generating part 1 is a bone conduction speaker. The bone conduction speaker extends along the lower edge of the helix through the front or back of the earlobe through the connecting arm 2 and then bends upward to abut against the user's face, so that there is no interference in the inner part of the ear around the external auditory canal, and no damage to the ear will be caused by long-term use. Preferably, the bone conduction speaker abuts against the user's face and the outer edge is close to the tragus to achieve a better bone conduction effect.

[0049] The bone conduction speaker transmits sound to the hearing system through the bone, thus generating hearing. Generally speaking, the bone conduction speaker mainly generates and conducts sound through the following steps: Step 1, the bone conduction speaker obtains or generates a signal containing sound information, such as an electrical 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 housing of the speaker through the transmission component.

[0050] Specifically, in Step 1, the bone conduction speaker can obtain or generate a signal containing sound information in different ways. The sound information can refer to video and audio files with a specific data format, or can refer to data or files that can generally carry data that can ultimately be 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 can come from an information generation, storage or transmission system outside the bone conduction speaker. The sound signal discussed here is not limited to an electrical signal, but can also include other forms such as optical signals, magnetic signals, and mechanical signals other than electrical signals. In principle, as long as the signal contains sound information that the speaker can use to generate vibration, it can be processed as a sound signal. The sound signal is not limited to a single signal source and can come from multiple signal sources. These multiple signal sources can be related or unrelated to each other. The way the sound signal is transmitted or generated 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 in a wired or wireless manner, or can directly obtain data from a storage medium to generate a sound signal. In some embodiments, a component with a sound collection function can be added to the bone conduction hearing aid. By picking up the ambient background sound and processing the received sound signal, a noise reduction effect can be achieved.

[0051] In this embodiment, the sound generating part 1 is separately arranged from the main control unit 3. Control elements such as a battery and a circuit board are arranged in the main control unit 3. The battery and the speaker in the sound generating part 1 can be made relatively large to meet longer battery life and high-quality sound.

[0052] The term "sound quality" used here can be understood as the quality of sound that can reflect the quality of sound, referring to the fidelity of audio after processes such as processing and transmission. Sound quality is mainly described by three elements: loudness, pitch, and timbre. Loudness is the subjective perception of the intensity of sound by the human ear, which is proportional to the logarithm of the sound intensity. The greater the sound intensity, the louder it sounds. And it is related to the frequency and waveform of the sound. Pitch, also known as the tone height, is the subjective perception of the vibration frequency of sound by the human ear. Pitch 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 is the subjective feeling of the characteristics of sound by the human ear. Timbre mainly depends on the spectral structure of the sound, and is also related to factors such as the loudness, duration, establishment 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 size, and the phase relationship. Different spectral structures result in different timbres. Even if the fundamental frequency and loudness are the same, if the harmonic structures are different, the timbres are also different.

[0053] In this application, the main body of the earphone is clamped on the side and / or lower part of the ear by the ear clip 4 to be away from the upper part of the ear, that is, the position avoiding the upper edge of the helix, which solves the problem of overlap and compression when the earphone and other devices are worn on the upper ear contour, and improves the comfort of wearing and using with other devices at the same time. Among them, the side part of the ear can be the side of the helix of the ear, the helix fossa, the antihelix, and the antitragus. The lower part of the ear can be the position of the earlobe. In this application, as long as the ear clip 4 can be clamped on the side and / or lower part of the ear, all existing positions that can be clamped on the ear except above the helix are acceptable, as long as the earphone can be prevented from falling off. Whether the ear clip 4 is clamped on the side part of the ear or the lower part of the ear or both the side part and the lower part of the ear at the same time is determined by the shape of the ear clip 4.

[0054] As Figures 10 - 16 shown, the ear clip 4 includes a first clamping portion 41 and a second clamping portion 42 that are oppositely arranged to cooperate to provide 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. The second ends of the first clamping portion 41 and the second clamping portion 42 are arranged facing each other and cooperate to provide an interacting clamping force to clamp on the side and / or lower part of the ear.

[0055] Among them, the first ends of the first clamping portion 41 and 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 the opposite end faces of the main control unit 3. As Figure 12 shown, for the convenience of connection, it is preferably connected to the opposite end faces of the main control unit 3. The connection method between the first clamping portion 41, the second clamping portion 42 and the main control unit 3 can be a snap connection, a hot pressing, a riveting, a bonding, or an injection molding, etc.

[0056] Both the first clamping part 41 and the second clamping part 42 include at least one clamping member 4a. The clamping members 4a in the first clamping part 41 and the second clamping part 42 protrude outward away from the helix so that a receiving space is formed between the clamping members 4a of the first clamping part 41 and the second clamping part 42 for receiving the outer edge of the helix. It should be noted that the number of clamping members 4a in the first clamping part 41 and the second clamping part 42 may be the same or different. When the number of clamping members 4a in the first clamping part 41 and the second clamping part 42 is different, the clamping members 4a in the first clamping part 41 and the clamping members 4a in the second clamping part 42 are arranged staggeredly to increase the clamping stability.

[0057] When the number of clamps in the first clamping part 41 and the second clamping part 42 is the same, the clamping members 4a in the first clamping part 41 and the clamping members 4a in the second clamping part 42 are arranged in one-to-one correspondence. Each corresponding pair of clamping members 4a in the first clamping part 41 and the second clamping part 42 can be called a pair of clamping members 4a. To achieve clamping balance, the distance between each pair of clamping members 4a can be changed, and multiple pairs of clamping members 4a can be provided, such as Figures 10 - 15 two pairs of clamping members 4a, such as Figure 16 three pairs of clamping members 4a. Of course, one pair or four pairs or more clamping members 4a can be provided according to the actual situation.

[0058] such as Figure 10 、 Figure 12 、 Figure 14 、 Figure 16 Preferably, the ear clip 4 includes two or three pairs of clamping members 4a. The clamping members 4a in the first clamping part 41 and the second clamping part 42 are arranged along the extending direction of the main control unit 3, and the clamping members 4a in the first clamping part 41 and the clamping members 4a in the second clamping part 42 are arranged in one-to-one correspondence. It should be noted that when the extending distance of the provided clamping members 4a is short, the ear clip 4 clamps on the side or lower part of the ear. When the extending distance of the provided clamping members 4a is long, the ear clip 4 can clamp on the side and lower part of the ear at the same time.

[0059] Preferably, the clamping member 4a is made of an elastic material. The ear clip 4 can be elastically opened and closed to clamp on the side and / or lower part of the ear. The first ends of the clamping members 4a of the first clamping part 41 and the second clamping part 42 are respectively connected to the opposite end faces of the main control unit 3, and the second ends of the first clamping part 41 and the second clamping part 42 are opposite to form an opening, 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.

[0060] such as Figure 3As shown, each pair of clamping members 4a can form a circular arc structure, a U-shaped structure, and a V-shaped structure with an opening relative to each other, preferably a circular 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 included angle F between the openings of the clamping members 4a in the first clamping portion 41 and the second clamping portion 42 is such that 20° < F < 50°. When each pair of clamping members 4a corresponds to a non-circular ring structure, the distance between the openings of the clamping members 4a in the first clamping portion 41 and the second clamping portion 42 is 2 - 5 mm.

[0061] As Figure 4 shown, to further ensure the stability of the ear side and / or the 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 15 mm - 35 mm. The vertical distance specifically refers to the distance of the midpoint horizontal line between the uppermost clamping member 4a and the lowermost clamping member 4a. And in the actual application process, the vertical distance between adjacent pairs of clamping members 4a can be set equally or unequally as long as it can ensure the stability of the ear side and / or the lower part of the ear clamped by the clamping member 4a.

[0062] Of course, the clamping member 4a can also be made of hard plastic. The first ends of the clamping members 4a in the first clamping portion 41 and the second clamping portion 42 are respectively hinged to the opposite end faces of the main control unit 3, and the second ends of the first clamping portion 41 and the second clamping portion 42 are arranged oppositely to cooperate in clamping the ear side and / or the lower part of the ear.

[0063] As Figure 6 shown, to ensure the stability of the sound generating portion 1 on the connecting arm 2 fitting on the tragus and the ear, and to prevent shaking when the user moves, the included angle a between the connecting line of the vertex of the upper edge of the main control unit 3 and the bottom point of the lower edge of the main control unit 3 and the side where the sound generating portion 1 abuts against the tragus or the ear is such that 10° < a < 30°. Among them, the vertex of the upper edge of the main control unit 3 and the bottom point of the lower edge refer to the two points with the farthest distance at both ends in the axial direction of the main control unit 3.

[0064] As Figure 7 shown, in some embodiments, the connecting arm 2 can be an integral elastic material structure. Among them, the first end of the connecting arm 2 is connected to the sound generating portion 1, and the second end of the connecting arm 2 can be connected to the ear clip 4. Of course, the second end of the connecting arm 2 can also be connected to the main control unit 3, and the second end of the connecting arm 2 can also be connected to both the main control unit 3 and the ear clip 4 at the same time, which is determined according to the specific shape of the connecting arm 2. Among them, the elastic material refers to a shape memory alloy, which is an intelligent material that can restore its original shape under specific conditions. It is preferably a metal wire 6 and a soft glue arranged outside the metal wire 6. The metal wire 6 is wound outside the audio wire 7, thereby improving the wearing comfort. At the same time, after being stretched and twisted by a large force, it can still return to the original state, and the light weight of the connecting arm 2 further improves the comfort.

[0065] As Figure 7 shown, to ensure high-quality sound, when the earphone is worn and the ear clip 4 clamps the side and / or lower part of the ear, the sound-emitting part 1 on the connecting arm 2 is located within the included angle b area. The vertex of the upper edge of the main control unit 3 and the bottom point of the lower edge of the main control unit 3 are connected to form a first connecting line. Taking the first connecting line as the reference line, the center point of the lower end of the control unit and the center point of the sound-emitting part 1 are connected to form a second connecting line. The included angle between the first connecting line and the second connecting line is b, and 30° < b < 90°.

[0066] As Figure 8 shown, in some other embodiments, the connecting arm 2 is a hard plastic part that does not deform during wearing. The connecting arm 2 includes a first connecting branch arm and a second connecting branch arm. The first end of the first connecting branch arm is connected to the sound-emitting part 1, the second end of the first connecting branch arm is hinged to the first end of the second connecting branch arm, and the second end of the second connecting branch arm is connected to the ear clip 4. Of course, the second end of the second connecting branch arm can also be connected to the main control unit 3, or the second end of the second connecting branch arm can be simultaneously connected to the main control unit 3 and the ear clip 4, which is determined according to the specific shape of the connecting arm 2.

[0067] As Figure 9 shown, in some other embodiments, the connecting arm 2 is a hard plastic part formed integrally. The first end of the connecting arm 2 is connected to the sound-emitting part 1, and the second end of the connecting arm 2 is hinged to the main control unit 3. Of course, the second end of the connecting arm 2 can be hinged to the ear clip 4, or the second end of the connecting arm 2 can be simultaneously hinged to the main control unit 3 and the ear clip 4, which is determined according to the specific shape of the connecting arm 2.

[0068] As Figure 8 and Figure 9 shown, to ensure high-quality sound, when the connecting arm 2 is worn on the earphone and the ear clip 4 clamps the side and / or lower part of the ear, the sound-emitting part 1 on the connecting arm 2 can swing within a certain range to adapt to the usage conditions of different users. Specifically, the included angle by which the sound-emitting part 1 can swing clockwise around the hinge point is c, 0° < c < 35°, and the included angle by which the sound-emitting part 1 swings counterclockwise around the hinge point is d, 0° < d < 50°. Among them, taking the initial position of the sound-emitting part 1 as the swing reference, the initial position of the sound-emitting part 1 is the position where it is close to the face and the outer edge is close to the tragus.

[0069] It should be noted that in the actual application process, according to the actual situation, such as Figure 11 , Figure 13 and Figure 15 shown, the connecting arm 2 can be bent upward in front of or behind the earlobe. As Figures 10 - 15 shown, when worn, the main control unit 3 can be arranged on the rear side, side or front side of the side and / or lower part of the ear. As Figure 7 and Figure 8As shown, the second end of the connecting arm 2 can be connected to the ear clip 4 and / or the main control unit 3.
