Description

Technical Field

[0001] The present application relates to the field of earphone technology, and more specifically, to a transducer component, an earphone, and an earphone system. Background Art

[0002] Bone conduction headphones are headphones that use human bones as a medium to transmit sound directly to the auditory organ without passing through the external auditory canal and eardrum. Bone conduction headphones can convert sound into mechanical vibrations. When the headphones are working, the transducer component that is in contact with the human skin will vibrate. The vibration of the transducer component can be transmitted to the human auditory nerve through the human skin, subcutaneous tissue and bones, allowing the person to hear the sound. The sound conduction of bone conduction headphones does not require the vibration of the eardrum, which not only improves comfort and protects the user's hearing, but also allows the user to still hear external sounds. It has its unique advantages. The shell of the transducer component and the bracket inside the shell are usually connected by glue. However, when there is an excess of glue between the shell and the bracket, glue overflow will occur when the shell and the bracket are connected. The glue overflows to the surface of the transducer component, which affects the overall appearance of the headphones and is not easy to clean. Utility Model Content

[0034] Bone conduction headphones are headphones that use human bones as a medium to transmit sound directly to the auditory organ without passing through the external auditory canal and eardrum. Bone conduction headphones can convert sound into mechanical vibrations. When the headphones are working, the transducer component that is in contact with the human skin will vibrate. The vibration of the transducer component can be transmitted to the human auditory nerve through the human skin, subcutaneous tissue and bones, so that the person can hear the sound. The sound conduction of bone conduction headphones does not require the vibration of the eardrum, which not only improves comfort, but also protects the user's hearing and allows the user to still hear external sounds. It has its unique advantages. The shell of the transducer component and the bracket inside the shell are usually connected by glue. However, when there is an excess of glue between the shell and the bracket, glue overflow will occur when the shell and the bracket are connected. The glue overflows to the surface of the transducer component, which will affect the overall appearance of the headphones and is not easy to clean. In order to solve this problem, the embodiment of the present application provides a transducer component 100( Figure 2 As shown), earphones 1000 ( Figure 1 shown) and earphone system 10000 ( Figure 6shown).

[0035] See also Figure 1 and Figure 2 The earphone 1000 of the embodiment of the present application includes a transducer assembly 100. In some embodiments, the earphone 1000 includes a bone conduction earphone 1000 and an air conduction earphone 1000.

[0036] Among them, the bone conduction earphones 1000 use the human skeleton as a medium, and the bone conduction earphones 1000 convert sound into mechanical vibrations. The mechanical vibrations transmit sound waves through the human skeleton so that the user can hear the sound. The sound of the bone conduction earphones 1000 acts on the bones, and long-term use will not cause a significant impact on the eardrum of the user's ear, which can effectively protect the user's hearing. The air conduction earphones 1000 transmit sound through air vibrations, and the air conduction earphones 1000 have good sound quality and penetration. The earphones 1000 of the present application are explained by taking the bone conduction earphones 1000 as an example, and the bone conduction earphones 1000 of the present application can be swimming earphones 1000, and the user can wear the bone conduction earphones 1000 for swimming and diving. The bone conduction earphones 1000 have good waterproof performance.

[0037] See also Figure 1 and Figure 2 The transducer assembly 100 of the present application is used to fit into the human skin. When the earphone 1000 is in use, the transducer assembly 100 can generate vibrations, which are conducted through the human bones, so that the user can hear the sound. The earphone 1000 of the present application also includes a function box assembly 300, which is electrically connected to the transducer assembly 100. The function box assembly 300 may include a battery box assembly 303 and / or a control box assembly 301. The control box assembly 301 can be used to control the power on and off of the earphone 1000 and adjust the volume of the earphone 1000. The battery box assembly 303 includes a battery, which is used to power other components of the earphone 1000 so that the earphone 1000 can work normally.

[0038] In some embodiments, the earphones 1000 further include an ear hook 500 and a back hook 700. The ear hook 500 is used to electrically connect the battery compartment assembly 303 and the transducer assembly 100, and to electrically connect the control box assembly 301 and the transducer assembly 100. The back hook 700 is used to electrically connect the battery compartment assembly 303 and the control box assembly 301. When a user wears the earphones 1000, the back hook 700 of the earphones 1000 is worn on the head, and the ear hook 500 of the earphones 1000 is worn behind the ear, thereby improving the wearing stability of the earphones 1000 and preventing the earphones 1000 from falling off when the user is outdoors or exercising.

[0039] See also Figures 3 to 5The transducer assembly 100 of the embodiment of the present application includes a first shell 10, a second shell 30, and a bracket 50. The second shell 30 is connected to the first shell 10 and together form a receiving cavity 31. The bracket 50 is located in the receiving cavity 31 and is connected to the second shell 30. The bracket 50 and the first shell 10 together form a mounting cavity 51. The bracket 50 is provided with a through hole 53. The mounting cavity 51 is provided with a glue receiving portion 11. The through hole 53 corresponds to and is connected to the glue receiving portion 11.

[0040] Specifically, the first shell 10 and the second shell 30 can be connected by snap-fitting, interference fitting or bonding, etc. For example, the first shell 10 and the second shell 30 can be connected by bonding. Preferably, the first shell 10 and the second shell 30 can be bonded together using waterproof glue. At this time, the connection between the first shell 10 and the second shell 30 is relatively stable, the first shell 10 is not easy to fall off relative to the second shell 30, and the waterproof effect between the first shell 10 and the second shell 30 is good, and external liquid is not easy to enter the accommodating chamber 31 from the gap between the first shell 10 and the second shell 30. The accommodating chamber 31 is used for the bracket 50 and other components of the transducer assembly 100 to be installed therein, and external liquid is not easy to enter the accommodating chamber 31, so that the components in the accommodating chamber 31 are not easy to be damaged.

[0041] See also Figures 3 to 5 One side of the bracket 50 is fixedly connected to the second shell 30, and the other side of the bracket 50 is used to install the vibration component 70 of the transducer assembly 100, so that the vibration component 70 of the transducer assembly 100 can be fixedly connected to the second shell 30 through the bracket 50. The bracket 50 and the second shell 30 of the present application can be connected by bonding, so that the connection between the bracket 50 and the second shell 30 is relatively stable, and can effectively prevent external liquid from entering the accommodating cavity 31 through the gap between the bracket 50 and the second shell 30. When connecting the bracket 50 to the second shell 30, waterproof glue can be first applied to the side of the bracket 50 facing away from the installation cavity 51, and then the second shell 30 can be pressed tightly onto the bracket 50. The through hole 53 is used to allow the waterproof glue between the bracket 50 and the second shell 30 to flow into the glue containing portion 11 through the through hole 53, thereby effectively preventing the waterproof glue from flowing out through the gap between the bracket 50 and the second shell 30 to the surface of the transducer component 100. The overall aesthetics of the transducer component 100 is good, and there is no need to clean the waterproof glue on the surface of the transducer component 100, so the installation of the transducer component 100 is relatively simple.

[0042] The number of through holes 53 can be one, two, three, four or more. When the number of through holes 53 is one, the through hole 53 can be provided at any position of the bracket 50. In this case, the structure of the bracket 50 is relatively simple and the processing is relatively simple. When the number of through holes 53 is multiple, the multiple through holes 53 can be evenly or unevenly distributed on the bracket 50. In this case, the number of the glue-containing parts 11 can also be multiple, and the multiple glue-containing parts 11 correspond to the multiple through holes 53 respectively. The waterproof glue on the bracket 50 can quickly pass through the multiple through holes 53 into the glue-containing part 11, which can further prevent the waterproof glue between the bracket 50 and the second shell 30 from flowing out to the surface of the transducer component 100.

[0043] See also Figures 3 to 5 The mounting cavity 51 is used for installing the vibration component 70 and other components of the transducer assembly 100 therein. The glue holding portion 11 is used to accommodate the waterproof glue flowing out from the through hole 53, which can prevent the waterproof glue from flowing to other components in the mounting cavity 51 and affecting the normal operation of other components. In some embodiments, the glue holding portion 11 is provided with a glue holding space 111, which is connected to the through hole 53. The glue holding space 111 is used to store the waterproof glue flowing from the through hole 53. The side of the bracket 50 facing the mounting cavity 51 abuts against the top wall of the glue holding portion 11. In the thickness direction of the transducer assembly 100, the through hole 53 corresponds to and is connected to the glue holding portion 11. When the bracket 50 is connected to the second shell 30, the bracket 50 and the second shell 30 jointly extrude the waterproof glue, and the waterproof glue can flow directly into the glue holding portion 11 through the through hole 53. Thus, the waterproof glue can be effectively prevented from flowing out of the gap between the through hole 53 and the glue holding portion 11.

[0044] In the transducer assembly 100 of the embodiment of the present application, the bracket 50 is provided with a through hole 53, and the mounting cavity 51 is provided with a glue-containing portion 11, and the through hole 53 corresponds to and is connected to the glue-containing portion 11. The bracket 50 and the second shell 30 can be bonded together by waterproof glue. When the bracket 50 and the second shell 30 are connected and the bracket 50 and the second shell 30 jointly extrude the waterproof glue, the waterproof glue can flow into the glue-containing portion 11 through the through hole 53, and the waterproof glue can be stored in the glue-containing portion 11. This can avoid the problem of the waterproof glue between the bracket 50 and the second shell 30 overflowing onto the surface of the transducer assembly 100. The overall aesthetics of the transducer assembly 100 are good, and there is no need to clean the waterproof glue on the surface of the transducer assembly 100, so the installation of the transducer assembly 100 is relatively simple.

[0045] The energy conversion assembly 100 will be further described below with reference to the accompanying drawings.

[0046] See also Figures 3 to 5In some embodiments, the glue holding portion 11 is connected to the inner wall of the first shell 10, and the glue holding portion 11 and the inner wall of the first shell 10 together form a glue holding space 111. The first shell 10 is provided with a through-hole 13, which is connected to the glue holding space 111. The through-hole 13 is used to allow the power connector 90 to pass through the glue holding space 111 and enter the accommodating cavity 31.

[0047] Wherein, the adhesive containing portion 11 can be an integral structure or a split structure with the first shell 10. In the case where the adhesive containing portion 11 and the first shell 10 are an integral structure, the adhesive containing portion 11 and the first shell 10 can be integrally formed, the processing steps of the transducer assembly 100 are relatively simple, and the connection between the adhesive containing portion 11 and the first shell 10 is relatively stable. In the case where the adhesive containing portion 11 and the first shell 10 are a split structure, the adhesive containing portion 11 and the first shell 10 are detachably or non-detachably connected. In the case where the adhesive containing portion 11 and the first shell 10 are a split structure, the adhesive containing portion 11 and the first shell 10 are detachably or non-detachably connected. In the case where the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection, etc. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit, etc.

[0048] The perforation 13 is used to allow one end of the ear hook 500 to extend therethrough. An electrical connector 90 is provided inside the ear hook 500. When the ear hook 500 extends through the perforation 13 to connect with the transducer assembly 100, the electrical connector 90 can extend into the accommodating cavity 31 to electrically connect with the components within the accommodating cavity 31. Because waterproof adhesive is stored in the adhesive space 111, when the electrical connector 90 passes through the adhesive space 111 and enters the accommodating cavity 31, the portion of the electrical connector 90 within the adhesive space 111 will be secured by the waterproof adhesive, thereby preventing the electrical connector 90 within the accommodating cavity 31 from shaking or vibrating and generating noise.

[0049] See also Figure 5 In some embodiments, at least a portion of the glue holding portion 11 is separated from the inner wall of the first shell 10 and forms a first opening 113 and a second opening 115. The glue holding space 111 is connected to the through hole 53 through the first opening 113, and the glue holding space 111 is connected to the through hole 13 through the second opening 115.

[0050] The first opening 113 corresponds to and is connected to the through hole 53. During the connection between the bracket 50 and the second shell 30, the through hole 53 is used to allow the waterproof glue to flow to the first opening 113, and then flow into the glue holding space 111 through the first opening 113. In the length direction of the transducer assembly 100, the glue holding portion 11 of the present application is staggered with the through hole 13, thereby avoiding the problem that the glue holding portion 11 hinders the electrical connector 90 from extending into the accommodating cavity 31. A second opening 115 is provided on one side of the glue holding portion 11 close to the through hole 13. The electrical connector 90 can enter the glue holding space 111 through the second opening 115, and extend from the first opening 113 to enter the accommodating cavity 31, so that the electrical connector 90 can be electrically connected to the components in the accommodating cavity 31.

[0051] See also Figure 4 and Figure 5 Furthermore, in some embodiments, the transducer assembly 100 further includes a vibration component 70. The vibration component 70 is located in the mounting cavity 51 and is connected to the bracket 50. The vibration component 70 can vibrate when energized.

[0052] The electrical connector 90 extends into the accommodating cavity 31 and can be electrically connected to the vibration component 70. When the earphone 1000 is in use, the electrical connector 90 can supply power to the vibration component 70, so that the vibration component 70 can vibrate. At least a portion of the vibration component 70 is connected to the bracket 50. When the vibration component 70 vibrates, the vibration component 70 will drive the bracket 50 to vibrate, so that the bracket 50 can drive the first shell 10 and the second shell 30 to vibrate together. When the user wears the earphone 1000, the second shell 30 can fit against the human skin, and the vibration of the second shell 30 can be conducted through the human bones, so that the user can hear the sound. When the bracket 50 is provided with a through hole 53 and the mounting cavity 51 is provided with a glue accommodating portion 11, it can effectively prevent the waterproof glue on the bracket 50 from flowing into the vibration component 70 to affect the normal operation (vibration) of the vibration component 70.

[0053] See also Figure 4 and Figure 5 In some embodiments, the vibration component 70 includes a coil 72, a magnetic member 73 and a spring 75. The coil 72 is fixedly connected to the bracket 50 and surrounds the magnetic member 73. The coil 72 is also electrically connected to the electrical connector 90. The spring 75 is connected to both the bracket 50 and the magnetic member 73. The magnetic field generated by the coil 72 being energized and the magnetic field of the magnetic member 73 are coupled with each other to drive the magnetic member 73 to move. When the energization direction of the coil 72 changes, the magnetic member 73 can drive the spring 75 to vibrate.

[0054] Specifically, the coil 72 can be fixedly connected to the side of the bracket 50 facing the mounting cavity 51 by bonding. In this case, the structure of the bracket 50 is relatively simple, and no connecting structure is required on the bracket 50. In addition, the connection between the coil 72 and the bracket 50 is relatively stable. When both the vibrating component 70 and the bracket 50 vibrate, the coil 72 is not likely to become loose relative to the bracket 50. When the coil 72 surrounds the magnetic member 73, the magnetic field of the coil 72 and the magnetic field of the magnetic member 73 are well coupled, and the coil 72 can effectively drive the magnetic member 73 to move.

[0055] For example, when current flows through the coil 72 in a first direction, the coupling of the magnetic field of the coil 72 and the magnetic field of the magnetic member 73 causes the magnetic member 73 to move toward the second housing 30. When current flows through the coil 72 in a second direction, the coupling of the magnetic field of the coil 72 and the magnetic member 73 causes the magnetic member 73 to move toward the first housing 10, with the first direction being opposite to the second direction. When the direction of current supplied to the coil 72 by the electrical connector 90 alternates between the first and second directions, the magnetic member 73 can repeatedly move and vibrate. When the magnetic member 73 is connected to the spring 75, the spring 75 can vibrate along with the magnetic member 73. The vibration of the spring 75 can also cause the bracket 50 to vibrate, which in turn causes the first and second housings 10, 30 to vibrate together. The vibration of the first housing 10 can be transmitted through the human body's bones, allowing the user to hear sound.

[0056] The spring clip 75 can be integrally formed, for example, by punching and blanking a metal sheet. Alternatively, the spring clip 75 can be punched and blanked from a stainless steel sheet, depending on actual needs. The spring clip 75 of the present application is generally a thin, flat plate. The magnetic member 73 can be a permanent magnet, such as a ferrite magnet or a neodymium iron boron magnet. The magnetic member 73 of the present application is generally flat.

[0057] See also Figure 4 and Figure 5 Furthermore, in some embodiments, the transducer assembly 100 further includes a shield 71, which is located within the mounting cavity 51 and connected to the magnetic member 73. The shield 71 surrounds the magnetic member 73 and the coil 72. The shield 71 can be made of a magnetically isolating material. When the magnetic field of the coil 72 and the magnetic member 73 are coupled to each other, the shield 71 can be used to prevent the magnetic fields of the coil 72 and the magnetic member 73 from leaking out, thereby preventing the magnetic field from interfering with the operation of other components within the mounting cavity 51.

[0058] See also Figure 4 and Figure 5 In some embodiments, the vibration component 70 further includes a connecting member 77, the magnetic member 73 is provided with a first through-hole 731, the spring piece 75 is provided with a second through-hole 751, and the protective member 71 is provided with a third through-hole 713. The first through-hole 731, the second through-hole 751 and the third through-hole 713 all correspond to each other, and the connecting member 77 is provided with the first through-hole 731, the second through-hole 751 and the third through-hole 713 to connect the magnetic member 73 to the spring piece 75 and the protective member 71.

[0059] Connector 77 securely connects magnetic member 73, spring 75, and protective member 71. When magnetic member 73 vibrates, it drives spring 75 to vibrate with it. This also drives protective member 71 to vibrate with it, ensuring relative fixation between magnetic member 73 and protective member 71. Protective member 71 effectively prevents leakage of the magnetic field from magnetic member 73. Connector 77 can be made of a non-magnetic material, such as stainless steel or an aluminum alloy.

[0060] See also Figure 4 and Figure 5 In some embodiments, the connecting member 77 is provided with a fourth through-hole 771, which allows the space between the second shell 30 and the bracket 50, and the space between the vibration component 70 and the first shell 10 to communicate, so that the air pressure at both ends of the magnetic member 73 remains consistent.

[0061] When the transducer assembly 100 is in use, the vibrating assembly vibrates back and forth within the accommodating chamber 31. During this back-and-forth vibration of the vibrating component 70, the fourth through-hole 771 maintains consistent air pressure on both sides of the magnetic member 73 (vibrating component 70), thereby preventing uneven air pressure on both sides of the magnetic member 73 and causing poor vibration of the vibrating component 70. Providing the fourth through-hole 771 in the connecting member 77 ensures balanced vibration of the vibrating component 70, thereby improving the accuracy of the transducer assembly's response and enhancing the performance of the bone conduction earphone 1000.

[0062] See also Figure 4 and Figure 5 Furthermore, in some embodiments, the vibration component 70 also includes a first magnetic conductive member 78 and a second magnetic conductive member 79. The first magnetic conductive member 78 and the second magnetic conductive member 79 are both arranged between the magnetic member 73 and the spring 75. The first magnetic conductive member 78 and the second magnetic conductive member 79 are used to stably transfer the magnetic field of the coil 72 to the magnetic member 73.

[0063] The first magnetic conductive member 78 is roughly shaped like a thin flat plate and is made of a magnetic conductive material. The second magnetic conductive member 79 is roughly shaped like a thin flat plate and is made of a magnetic conductive material. The provision of the first and second magnetic conductive members 78, 79 ensures that the magnetic field generated by the coil 72 is stably transmitted to the magnetic member 73, thereby improving the utilization rate of the magnetic field energy and ensuring the timely and efficient vibration of the vibrating component 70.

[0064] See also Figure 4 and Figure 5In some embodiments, the connecting member 77 is sequentially passed through the spring piece 75, the first magnetic conductive member 78, the second magnetic conductive member 79, the magnetic member 73, and the protective member 71 to fix the spring piece 75, the first magnetic conductive member 78, the second magnetic conductive member 79, the magnetic member 73, and the protective member 71 in connection.

[0065] The spring piece 75, the first magnetic conductive member 78, the second magnetic conductive member 79, the magnetic member 73, and the protective member 71 are tightly connected. When the magnetic member 73 vibrates, the magnetic member 73 drives the spring piece 75, the first magnetic conductive member 78, the second magnetic conductive member 79, and the protective member 71 to vibrate together. Furthermore, the vibrating component 70 does not require multiple connecting structures to connect the spring piece 75, the first magnetic conductive member 78, the second magnetic conductive member 79, the magnetic member 73, and the protective member 71, resulting in a relatively simple structure.

[0066] See also Figure 6 The earphone system 10000 of the embodiment of the present application includes the earphone 1000 of the above embodiment and a charging box 3000, which is used to charge the earphone 1000. The charging box 3000 is provided with a charging compartment. When the earphone 1000 needs to be charged, the battery box of the earphone 1000 can be accommodated in the charging compartment, and the charging box 3000 can charge the battery inside the battery compartment.

[0067] In the earphone system 10000 of the embodiment of the present application, the bracket 50 is provided with a through hole 53, and the mounting cavity 51 is provided with a glue-receiving portion 11, and the through hole 53 corresponds to and is in communication with the glue-receiving portion 11. The bracket 50 and the second shell 30 can be bonded together by means of waterproof glue. When the bracket 50 and the second shell 30 are connected and the bracket 50 and the second shell 30 jointly extrude the waterproof glue, the waterproof glue can flow into the glue-receiving portion 11 through the through hole 53, and the waterproof glue can be stored in the glue-receiving portion 11. This can avoid the problem of the waterproof glue between the bracket 50 and the second shell 30 overflowing onto the surface of the transducer assembly 100. The overall aesthetics of the transducer assembly 100 are improved, and there is no need to clean the waterproof glue on the surface of the transducer assembly 100, making the installation of the transducer assembly 100 relatively simple.
