Detailed Implementation

[0069] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0070] In the embodiments described in this application, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can be an electrical connection, or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0071] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are merely used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0072] The following combination Figures 1 to 5 The headphones described in the embodiments of this application will be described in detail.

[0073] In embodiments of this application, the earphone includes: a suspension shell 210, an audio shell 110, an ear hook 300, a sound-generating component 120, and a circuit board 240. The suspension shell 210 defines a suspension receiving cavity 211; at least a portion of the suspension receiving cavity 211 is a sealed space; the audio shell 110 defines an audio receiving cavity 111; the ear hook 300 is connected to both the audio shell 110 and the suspension shell 210; the sound-generating component 120 is disposed in the audio receiving cavity 111; at least a portion of the circuit board 240 is disposed within the sealed space.

[0074] In related technologies, the headphone structure includes an audio structure and a battery structure. The battery structure has poor waterproof performance, resulting in poor adaptability of the headphone structure. However, in the headphone of this application, at least a portion of the suspension cavity 211 is a sealed space, and at least a portion of the circuit board 240 is disposed within the sealed space. This makes the portion of the circuit board 240 located within the sealed space waterproof, thereby improving the safety of the circuit board 240 in use and enhancing the adaptability of the headphone.

[0075] In this embodiment, the shape of the suspension shell 210 is not limited. For example, the suspension shell 210 can be in the form of a columnar structure, an elliptical structure, a teardrop shape, etc. The suspension shell 210 can be used to fit with the wearer's head. When worn, the suspension shell 210 can be in contact with the wearer's head or have a small gap with the wearer's head, so that the wearer's head can support the suspension shell 210, thereby improving the wearing stability and comfort of the headphones.

[0076] The suspension receiving cavity 211 may be a sealed space, or it may be a sealed space of all or part of the suspension receiving cavity 211.

[0077] As an example, such as Figure 2 As shown, the suspension housing 210 may include a third half-shell 201 and a fourth half-shell 202; a suspension receiving cavity 211 is defined between the third half-shell 201 and the fourth half-shell 202; the third half-shell 201 and the fourth half-shell 202 are sealed together so that the suspension receiving cavity 211 is sealed at the gap between the third half-shell 201 and the fourth half-shell 202. Of course, in other examples, the suspension housing 210 may also be a single structure.

[0078] Here, the sealing method between the third half-shell 201 and the fourth half-shell 202 is not limited. For example, the third half-shell 201 and the fourth half-shell 202 can be connected by bonding, welding, or other methods. In this case, the entire contact area between the third half-shell 201 and the fourth half-shell 202 can be connected by bonding, welding, or other methods to achieve a sealing arrangement between them. Of course, the third half-shell 201 and the fourth half-shell 202 can also be connected by snap-fit, threaded structure, or other methods. In this case, sealant, sealing rings, or other materials can be used to fill the space between the third half-shell 201 and the fourth half-shell 202 to achieve a sealing arrangement between them.

[0079] The fourth half-shell 202 and the third half-shell 201 can be arranged opposite each other in the thickness direction N2 of the suspension shell 210, such as... Figure 2 As shown. Of course, the fourth half-shell 202 and the third half-shell 201 can also be arranged opposite each other in other directions of the suspension shell 210.

[0080] The thickness direction N2 of the suspension shell 210 can be the direction in which the wearer's head is supported by the suspension shell 210.

[0081] In this embodiment, the shape of the audio shell 110 is not limited. For example, the audio shell 110 may be columnar, elliptical, teardrop-shaped, etc. The audio shell 110 can be used to fit with the wearer's ear. When worn, the audio shell 110 may be in contact with the wearer's ear or have a small gap with the wearer's ear so as to support the audio shell 110 through the wearer's ear.

[0082] As an example, such as Figure 4 As shown, the audio housing 110 may include a first half-shell 101 and a second half-shell 102 disposed opposite to each other; the second half-shell 102 and the first half-shell 101 may be connected by means of adhesive, snap-fit, welding, etc., to facilitate the installation of the sound-generating assembly 120. Here, an audio receiving cavity 111 is defined between the second half-shell 102 and the first half-shell 101. Of course, in other examples, the audio housing 110 may also be a single structure.

[0083] In the embodiments of this application, the structure of the ear hook 300 is not limited. For example, the ear hook 300 can be a strip structure with a circular or elliptical cross-section.

[0084] The ear hook 300 can be connected to the audio shell 110 and the suspension shell 210 by means of adhesive bonding, snap-fitting, welding, etc.

[0085] In this embodiment, the sound-generating component 120 can be disposed in the audio receiving cavity 111 by means of bonding, snap-fitting, welding, etc. The structure of the sound-generating component 120 is not limited. For example, the sound-generating component 120 can be a speaker or other structure capable of producing sound.

[0086] In this embodiment, the circuit board 240 can be disposed in the suspension receiving cavity 211 by means of bonding, snapping, welding or other methods.

[0087] The circuit board 240 being disposed at least in the sealed space may include the entire circuit board 240 being disposed in the sealed space, or it may include a portion of the circuit board 240 being disposed in the sealed space.

[0088] The circuit board 240 and the sound-generating component 120 can be electrically connected, and the manner in which the circuit board 240 and the sound-generating component 120 are electrically connected is not limited. For example, the circuit board 240 and the sound-generating component 120 can be electrically connected via a connecting cable 400.

[0089] In some optional implementations of the embodiments of this application, the headphones may further include a control component 250, which is disposed on the suspension shell 210; the control component 250 is used to control the sound-producing component 120 to produce sound.

[0090] Of course, in other implementations, the control component 250 can also be set in the audio shell 110.

[0091] In this implementation, the control component 250 can be used to adjust the volume of the sound emitted by the sound-emitting component 120. The operator can increase or decrease the volume by pressing different areas of the control component 250 or by pressing the control component 250 a different number of times. For example, the control component 250 can also be used to start or stop the sound emission of the sound-emitting component 120. Here, pressing the control component 250 switches between starting and stopping the sound emission of the sound-emitting component 120. Of course, in other examples, the control component 250 can also be used to control the opening or closing of headphones.

[0092] In this implementation, the control component 250 is not limited to any particular type. For example, the control component 250 may include mechanical buttons, such as... Figure 1 and Figure 5 As shown, here, mechanical buttons prevent the control component 250 from being accidentally operated by foreign objects such as the wearer's hair, thereby improving the safety of operating the control component 250. Alternatively, the control component 250 may include touch buttons to make the headphones look cleaner.

[0093] In this implementation, such as Figure 2 and Figure 5As shown, the suspension housing 210 may have a first through hole 205 communicating with the suspension receiving cavity 211; the control component 250 may include: a control key 251, an elastic element 253 and a button 252. The control key 251 can be mounted on the circuit board 240 by means of bonding, snap-fitting, welding, etc.; the elastic element 253 can be mounted in the suspension receiving cavity 211 by means of bonding, snap-fitting, welding, etc., and corresponds to the position of the control key 251; the elastic element 253 is sealed to the wall of the first through hole 205, so that the suspension receiving cavity 211 is sealed at the first through hole 205; the button 252 is movably mounted at the first through hole 205; the button 252 is located on the side of the elastic element 253 opposite to the control key 251; the button 252 is used to press the control key 251 through the elastic element 253; by sealing the elastic element 253 to the wall of the first through hole 205, the button 252 can be mounted on the suspension shell 210, and the suspension receiving cavity 211 can be sealed.

[0094] The material of the elastic element 253 is not limited. For example, the material of the elastic element 253 can be rubber, polyurethane, polytetrafluoroethylene, polyvinyl chloride, etc.

[0095] The method by which the elastic element 253 is sealed to the peripheral wall of the first through hole 205 is not limited. For example, the elastic element 253 may be pressed against the peripheral wall of the first through hole 205, and the elastic element 253 may be in a deformed state, thereby sealing the elastic element 253 to the peripheral wall of the first through hole 205. Alternatively, the elastic element 253 may be connected to the peripheral wall of the first through hole 205 by bonding or welding to achieve a sealing effect.

[0096] The material of button 252 is not limited. For example, button 252 can be made of metal, plastic or other materials with a certain degree of rigidity so that the operator's pressing pressure can be quickly transmitted to the control key.

[0097] Button 252 does not contact control key 251, but button 252 can touch control key 251 through elastic element 253. Pressing the control key by contacting it through elastic element 253 reduces the rigid contact force between button 252 and control key 251, thus reducing wear on control key 251 caused by pressing. Simultaneously, the contact between button 252 and control key 251 through elastic element 253 also reduces the impact force of pressing button 252 on control key 251, extending the lifespan of control key 251.

[0098] As an example, such as Figure 2As shown, a portion of the elastic element 253 has a protrusion 2531 on one side and a receiving groove 2532 on the other side; the protrusion 2531 and the control key 251 are arranged adjacent to each other in the moving direction of the button 252, the first end of the button 252 is inserted into the receiving groove 2532, and the second end of the button 252 is exposed through the first through hole 205 so that the button 252 can be pressed through the second end of the button 252.

[0099] Here, by inserting the first end of the button 252 into the receiving groove 2532, the volume of the elastic element can be increased, thereby improving the elastic force of the elastic element. Furthermore, by placing the elastic element on the outer periphery of the button 252, the elastic force of the elastic element can be distributed more evenly.

[0100] Here, the protrusion 2531 and the control key 251 are arranged adjacent to each other in the moving direction of the button 252, which means that the protrusion 2531 and the control key 251 are in contact or have a small gap in the moving direction of the button 252.

[0101] Of course, in other examples, the elastic element 253 can also be a plate-like structure.

[0102] In some optional implementations of the embodiments of this application, the suspension shell 210 may have a second through hole 206 communicating with the suspension receiving cavity 211; the earphone further includes: a charging part 230, the first end of the charging part 230 being connected to the circuit board 240, and the second end of the charging part 230 passing through the second through hole 206; the charging part 230 and the wall of the second through hole 206 are interference-fitted to seal the suspension receiving cavity 211 at the second through hole 206; the interference fit between the charging part 230 and the wall of the second through hole 206 enables the suspension receiving cavity 211 to be sealed at the second through hole 206.

[0103] Of course, in other examples, the charging part 230 and the wall of the second through hole 206 can also be spaced apart. Here, the charging part 230 and the wall of the second through hole 206 can also be sealed with sealant or sealing ring.

[0104] In this implementation, by placing the charging unit 230 and the circuit board 240 in the suspension receiving cavity 211, the installation volume of the audio housing 110 can be greatly reduced.

[0105] In this implementation, the charging unit 230 is electrically connected to the circuit board 240 and is able to charge the power supply 220.

[0106] In some optional implementations of this application, the earphone may further include: a pickup element 280 and a sealing element 500. The pickup element 280 may be disposed on the circuit board 240 by means of bonding, snapping, welding, etc.; the suspension shell 210 also has a pickup hole 207 corresponding to the position of the pickup element 280; the sealing element 500 is disposed between the circuit board 240 and the suspension shell 210 and corresponds to the position of the pickup element 280; the sealing element 500 has a through channel 510 communicating with the pickup hole 207; thereby allowing external sound to enter the pickup element 280 through the pickup hole 207 and the through channel 510; at the same time, by disposing of the sealing element 500 between the circuit board 240 and the suspension shell 210, the suspension receiving cavity 211 can also be sealed in areas other than the area where the pickup element 280 is disposed, the area where the circuit board 240 and the pickup element 280 are disposed, and the area where the sealing element 500 is disposed.

[0107] Of course, in other implementations, the pickup element 280 can also be set in the ear hook 300 or the audio shell 110. Here, the suspension cavity 211 can also be a completely sealed space, and the entire circuit board 240 can also be set in a sealed space.

[0108] In this implementation, the structure of the sound pickup element is not limited. For example, the sound pickup element can be a microphone or other structure capable of picking up sound.

[0109] The pickup element 280 can be waterproof, meaning that even if water enters through the pickup hole 207, it will not affect the performance of the pickup element 280. Of course, the pickup element 280 may also not be waterproof.

[0110] In this implementation, the structure of the seal 500 is not limited. For example, the seal 500 can be a sealing structure such as sealant, sealing ring, or adhesive.

[0111] In this implementation, the earphone may further include a dustproof component 610. The dustproof component 610 can be installed at the through channel 510 by means of adhesive bonding, snap-fitting, or welding, thereby preventing external debris from entering. Here, the dustproof component 610 may also be waterproof, thereby preventing water and other liquid impurities from entering. The dustproof component 610 can be a breathable but waterproof structure.

[0112] In this implementation, such as Figure 2As shown, the pickup element 280 can be located on the side of the circuit board 240 away from the pickup hole 207; the circuit board 240 can have a first sound guide channel 243 corresponding to the position of the pickup element 280; the wall of the circuit board 240 on the periphery of the first sound guide channel 243 is sealed to the pickup element 280; the suspension shell 210 can also include: a sound guide structure 212, which defines a second sound guide channel 2121; the second sound guide channel 2121 is connected to the first sound guide channel 243 and the pickup hole 207 respectively; the sealing element 500 can be located between the sound guide structure 212 and the circuit board 240, and the through channel 510 is connected to the second sound guide channel 2121 and the first sound guide channel 243 respectively.

[0113] The wall of the circuit board 240 located on the periphery of the first sound guide channel 243 and the pickup element 280 can be sealed with sealant and sealing ring, so that the path from the pickup hole 207 to the pickup element 280 is sealed, preventing external liquids such as water from entering through the pickup hole 207 and entering other areas of the suspension receiving cavity 211 through the gap between the wall of the circuit board 240 located on the periphery of the first sound guide channel 243 and the pickup element 280, thereby ensuring that other areas of the suspension receiving cavity 211 are sealed.

[0114] By incorporating the sound-guiding structure 212, the installation space for the seal 500 can be reduced, thereby improving the sealing reliability of the seal 500. Alternatively, the suspension housing 210 may not include the sound-guiding structure 212.

[0115] In some optional implementations of this application, the audio housing 110 has an annular step 105 located within the audio receiving cavity 111, and the outer edge of the support 121 of the sound-generating component 120 rests on the step. The sound-generating component 120 divides the audio receiving cavity 111 into a first acoustic cavity 112 and a second acoustic cavity 113. The audio housing 110 has a sound-generating channel 114 communicating with the first acoustic cavity 112. Since the circuit board is not located within the audio receiving cavity 111, the first acoustic cavity 112 and the second acoustic cavity 113 are only used for the sound-generating component 120 to generate sound, thereby greatly improving the sound quality of the sound-generating component 120.

[0116] In this implementation, the headphones may further include: a first mesh 620, which covers the sound channel 114; the first mesh 620 is used for dust prevention and sound tuning.
