[0036] In addition, it is required to understand the present application not only through the actual terms used, but also through the meanings implied by each term.

[0037] The technical solutions provided by the embodiments of the present application are described in detail below in conjunction with the drawings.

[0038] The embodiments of the present application provide a headphone speaker. Referring to Figures 1 to 4 , the headphone speaker 10 provided by the embodiments of the present application includes: a diaphragm 11, a main body 12, a cover body 13 and a support member 14.

[0039] It should be noted that, by way of example, the diaphragm 11 can be made of flexible materials such as paper, plastic, carbon fiber and Kevlar fiber. The diaphragm 11 is used to convert an electrical signal into mechanical vibration and generate sound. The main body 12 can include a speaker bracket and various components fixedly connected to the speaker bracket.

[0040] Specifically, in the embodiments of the present application, the diaphragm 11 is connected to the main body 12, and the diaphragm 11 is provided with a first air hole 111. The main body 12 is provided with a second air hole 1211, a receiving cavity 1212, and a third air hole 1213 that are connected in sequence. The first air hole 111 is connected to the side of the second air hole 1211 facing away from the third air hole 1213. The cover body 13 is disposed in the receiving cavity 1212. The support member 14 is respectively connected to the cover body 13 and the main body 12, so that the cover body 13 is spaced apart from the peripheral portion of the third air hole 1213 to form a ventilation gap, and the first air hole 111 is connected to the second air hole 1211 through the second air hole 1211, the receiving cavity 1212, and the ventilation gap.

[0041] In this way, when the cover body 13 is not subjected to other driving forces, the support member 14 supports the cover body 13, so that the cover body 13 forms a ventilation gap with the peripheral portion of the third air hole 1213. Furthermore, the first air hole 111 is connected to the second air hole 1211 through the second air hole 1211, the receiving cavity 1212, and the ventilation gap, so as to utilize the air flow channel formed between the first air hole 111 and the second air hole 1211 to improve the air permeability of the headphone speaker 10.

[0042] In addition, when the diaphragm 11 vibrates to generate sound, the sound pressure generated by the vibration of the diaphragm 11 can drive the cover body 13 to move toward the peripheral portion of the third air hole 1213 to block the third air hole 1213. It should be noted that it can be understood that the headphone equipped with the headphone speaker 10 will be inserted into the user's ear canal during use, and the side where the diaphragm 11 is located faces the user's eardrum. In this way, when the diaphragm 11 vibrates, the gas in the area surrounded by the eardrum, the ear canal, and the diaphragm 11 will vibrate, so that the pressure of the gas in this area will increase. Therefore, the gas with a higher pressure in this area can overcome the force applied by the support member 14 to the cover body 13, so as to "push" the cover body 13 to move toward the third air hole 1213 and block the third air hole 1213. Therefore, when the headphone speaker 10 is in the sound-emitting state, the airtightness of the headphone speaker 10 can be improved by blocking the air flow channel formed between the first air hole 111 and the second air hole 1211, thereby improving the sound-emitting effect of the headphone speaker 10.

[0043] In this way, in the embodiments of the present application, when the headphone speaker 10 is in the non-sound-emitting state, the support member 14 supports the cover body 13, so that the cover body 13 forms a ventilation gap with the peripheral portion of the third air hole 1213. Furthermore, the first air hole 111 is connected to the second air hole 1211 through the second air hole 1211, the receiving cavity 1212, and the ventilation gap to form an air flow channel, so as to facilitate the gas exchange between the area in the ear canal and the external environment through the air flow channel, so as to prevent the user from experiencing symptoms such as ear canal dampness or itching.

[0044] In addition, when the headphone speaker 10 is in a sounding state, the sound pressure generated by the vibration of the diaphragm 11 can drive the cover 13 to move toward the peripheral portion of the third air hole 1213 to block the third air hole 1213. Thus, the airtightness of the headphone speaker 10 can be improved by blocking the air flow channel formed between the first air hole 111 and the second air hole 1211, thereby improving the sounding effect of the headphone speaker 10.

[0045] It can be seen from this that by adopting the solution provided by the embodiment of the present application, the air permeability of the headphone speaker 10 can be improved without reducing the sounding effect of the headphone speaker 10.

[0046] In some embodiments, the support member 14 is an elastic support member. In this way, when the acting force generated by the sound pressure generated by the vibration of the diaphragm 11 on the cover 13 is greater than the elastic support force applied by the elastic support member to the cover 13, the sound pressure generated by the vibration of the diaphragm 11 can "push" the cover 13 toward the third air hole 1213 to block the third air hole 1213.

[0047] In some embodiments, the elastic support member includes a first elastic member 141 and a second elastic member 142. The first elastic member 141 is used to apply a first elastic force from the cover 13 toward the third air hole 1213 to the cover 13, and the second elastic member 142 is used to apply a second elastic force opposite to the direction of the first elastic force to the cover 13, and the second elastic force is greater than the first elastic force. In other words, in the embodiment of the present application, two elastic members can be set in a group, one providing a support force to the cover 13 and the other providing a downward pulling force to the cover 13. In this way, by reasonably setting the difference between the elastic forces of the two elastic members, the support force applied by the elastic support member to the cover 13 can be made more accurate.

[0048] Exemplarily, in the case of ignoring the influence of gravity on each component, the first elastic member 141 applies a support force of 15 millinewtons to the cover 13, and the second elastic member 142 applies a downward pulling force of 13 millinewtons to the cover 13. Thus, when the acting force of the sound pressure generated by the vibration of the diaphragm 11 on the cover 13 is greater than 2 millinewtons, the cover 13 can be "pushed" toward the third air hole 1213 to block the third air hole 1213. If only an elastic member for applying a support force to the cover 13 is provided, it is relatively difficult to purchase an elastic member with a suitable elastic force. By adopting the solution provided by the embodiment of the present application, by setting two elastic members in a group, it is easier to purchase a suitable elastic member.

[0049] Exemplarily, the elastic support member includes multiple groups of elastic members, and each group of elastic members includes a first elastic member 141 and a second elastic member 142. The multiple groups of elastic members are evenly distributed in a circle around the axis of the third air hole 1213. For example, refer to Figure 3 and Figure 4The elastic support member includes four groups of elastic members, and the four groups of elastic members are evenly distributed around the axis of the third air hole 1213.

[0050] It should be noted that in some other embodiments, the support member 14 may include a first magnet and a second magnet. The first magnet is connected to the cover 13, and the second magnet is connected to the main body 12. The magnetic poles of the first magnet and the second magnet on the opposite sides are the same, so that the cover 13 can be supported by the principle that magnets of the same polarity repel each other. Of course, those skilled in the art may also use other devices to support the cover 13, which will not be listed here one by one.

[0051] It should also be noted that, in some special cases, the sound pressure generated by the earphone speaker 10 at certain moments may not be able to smoothly drive the cover 13 to completely block the third air hole 1213. Therefore, in order to improve the sound effect of the earphone speaker 10, when the earphone speaker 10 is in the sounding state, a background noise can be emitted, and the sound pressure generated by the background noise can be used to assist in driving the cover 13 to block the third air hole 1213. It can be understood that the background noise is mainly used to generate sound pressure to assist in driving the movement of the cover 13, and therefore, the volume generated by the background noise is as small as possible, so that the background noise is not easily perceived by the user.

[0052] In some embodiments, a sealing ring 15 is provided at the periphery of the third air hole 1213, and the sealing ring 15 is arranged around the third air hole 1213, and the sealing ring 15 is opposite to the cover body 13. In this way, when the diaphragm 11 vibrates and makes sound, the cover body 13 can abut against the sealing ring 15 to enhance the blocking effect of the cover body 13 on the third air hole 1213.

[0053] For example, a ring groove is provided on one side of the main body 12 facing the cover 13, and the ring groove is arranged around the outer circumference of the third air hole 1213. The sealing ring 15 can be arranged in the ring groove, and the side of the sealing ring 15 away from the groove bottom of the ring groove protrudes from the notch of the ring groove. Therefore, when the diaphragm 11 vibrates and makes sound, the cover 13 can abut against the side of the sealing ring 15 away from the groove bottom of the ring groove.

[0054] In order to enable those skilled in the art to better implement the solutions provided in the embodiments of the present application, more detailed examples are provided below for reference by those skilled in the art.

[0055] Combination Figure 2 and Figure 3 In some embodiments, the main body 12 includes a bracket 1221 and a tube 1222. The peripheral portion of the diaphragm 11 is connected to the bracket 1221, and the portion of the diaphragm 11 located at the periphery of the first air hole 111 is connected to one end of the tube 1222. The area surrounded by the tube 1222 forms the second air hole 1211. In this way, the first air hole 111 can be connected to the second air hole 1211.

[0056] In some embodiments, the main body 12 further includes an annular magnet 1223 and a connecting body 1224. The annular magnet 1223 is sleeved outside the tube body 1222. A perforation is provided at a portion of the bracket 1221 opposite to the tube body 1222. The annular magnet 1223 and the connecting body 1224 are respectively provided on both sides of the perforation. The annular magnet 1223, the hole wall of the perforation, and the connecting body 1224 enclose a receiving cavity 1212. A third air hole 1213 is provided at a portion of the connecting body 1224 opposite to the perforation. One end of the tube body 1222 facing the cover body 13 is spaced apart from the cover body 13. In this way, when the earphone speaker 10 is in a non-sounding state, the support member 14 supports the cover body 13, and the water vapor on one side of the diaphragm 11 can be dissipated to the external environment through the first air hole 111, the second air hole 1211, the receiving cavity 1212, the ventilation gap formed at the peripheral portion of the cover body 13 opposite to the third air hole 1213, and the third air hole 1213, thereby preventing the user from experiencing ear canal dampness symptoms.

[0057] In some embodiments, the earphone speaker 10 further includes a voice coil 16. The voice coil 16 is wound outside the first air hole 111. The voice coil 16 is connected to the diaphragm 11, and the annular magnet 1223 is sleeved inside the voice coil 16. In this way, when the voice coil 16 is energized, the magnetic field generated by the voice coil 16 interacts with the magnetic field generated by the annular magnet 1223, thereby driving the diaphragm 11 to vibrate with the voice coil 16 and emit sound.

[0058] Exemplarily, a portion of the diaphragm 11 between its outer periphery and the first air hole 111 is recessed toward the annular magnet 1223 to form an annular recess. The voice coil 16 can be connected to the annular recess. In addition, the annular magnet 1223 is sleeved inside the voice coil 16, and one side of the annular magnet 1223 facing away from the diaphragm 11 is connected to the bracket 1221. The tube body 1222 is sleeved inside the annular magnet 1223, and the outer peripheral surface of the tube body 1222 is connected to the annular magnet 1223.

[0059] The embodiment of the present application provides an earphone. In combination Figure 1 、 Figure 2 and Figure 5 , the earphone 1 provided by the embodiment of the present application includes: a housing 20 and any one of the earphone speakers 10 provided by the embodiment of the present application. The earphone speaker 10 is disposed inside the housing 20.

[0060] In some embodiments, a portion of the main body 12 located outside the periphery of the diaphragm 11 is hermetically connected to the inner wall of the housing 20. The housing 20 is provided with a sound outlet 21 and a ventilation port 22. The diaphragm 11 faces the sound outlet 21, the first air hole 111 is communicated with the sound outlet 21, and the third air hole 1213 is communicated with the ventilation port 22. When the earphone 1 is inserted into the ear canal, the sound outlet 21 faces the user's eardrum, and the ventilation port 22 faces away from the user's ear canal.

[0061] It should be noted that, by way of example, the earphone 1 is a Bluetooth earphone. The Bluetooth earphone can be in Bluetooth communication connection with an electronic device having a Bluetooth connection function.

[0062] When the earphone speaker 10 is in a non-sounding state, the ear canal can exchange gas with the external environment through the air flow channel between the first air hole 111 and the third air hole 1213. In addition, during the process of the user talking with others, the sound of others speaking can also be transmitted into the user's ear canal through the air flow channel between the first air hole 111 and the third air hole 1213. In this way, the user can talk with others normally without taking off the earphone.

[0063] When the earphone speaker 10 is in a sounding state, the air flow channel between the first air hole 111 and the third air hole 1213 is in a cut-off state, and the external environmental sound is not easily transmitted into the user's ear canal through the air flow channel between the first air hole 111 and the third air hole 1213. In this way, the sound quality of the earphone 1 can be improved.

[0064] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0065] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the embodiments of the present application.
