[0026] Wireless headphones have gained market acceptance due to their advantages such as being wireless, intelligent, having good sound quality, being small in size, and being comfortable to wear. As the market acceptance of wireless headphones increases, user demands are also constantly rising. Today, users not only want wireless headphones to be superior in appearance and function, but also pay special attention to the battery replacement issue.
[0027] Current wireless earphones typically use soldered wires to assemble the battery compartment by snapping together the upper and lower shells and sealing it with glue to achieve a waterproof seal. Therefore, if the battery needs to be replaced due to lifespan or malfunction, consumers cannot easily replace it themselves.
[0028] This invention proposes a wireless earphone to solve the problem of difficult battery replacement in wireless earphones, thereby improving the ease of use of wireless earphones.
[0029] Please see 1 and Figure 2 In one embodiment, the wireless earphone includes a housing 100, a battery unit 300, and a cover 200.
[0030] The housing 100 has a receiving cavity and an opening 140 communicating with the receiving cavity. In one embodiment, the housing 100 includes a front shell 110, a middle shell 120, and a rear shell 130 connected together, the front shell 110, the middle shell 120, and the rear shell 130 together form a receiving cavity, and the opening 140 is located in the front shell 110. In one embodiment, the front shell 110, the middle shell 120, and the rear shell 130 are sealed together by means of bonding or other methods. Of course, in other embodiments, the front shell 110, the middle shell 120, and the rear shell 130 may also be integrally formed. Here, the housing 100 is not limited. The material of the housing 100 can be configured as polypropylene, polyethylene, or polycarbonate, which have high hardness and wear resistance. Here, the specific material of the housing 100 is not limited.
[0031] The battery unit 300 is disposed within the receiving cavity. In one embodiment, the battery unit 300 includes at least one cylindrical battery for easy user operation. The specific number of batteries is not limited here. Of course, in other embodiments, the battery may be a lithium battery or other batteries adapted to the receiving cavity; this is not a limitation.
[0032] The cover 200 is detachably disposed on the opening 140 to open or close the opening 140. The cover 200 includes a cover body 210 and a flexible sealing body 220. The flexible sealing body 220 is disposed circumferentially along the cover body 210 and is radially deformable along the housing 100 to be detachably disposed on the opening 140 and to have an interference fit with the opening 140. In one embodiment, when the cover 200 is disposed on the opening 140, the cover body 210 can completely cover the opening 140, and the flexible sealing body 220 is in close contact with the inner wall of the opening 140 to better protect the battery cell 300. In one embodiment, the flexible sealing body 220 is disposed in a ring around the circumference of the cover body 210, and the cross-sectional dimension of the flexible sealing body 220 is slightly larger than the cross-sectional dimension of the opening 140 to achieve an interference fit between the flexible sealing body 220 and the opening 140. Here, no specific limitation is made on the cross-sectional dimensions of the opening 140 and the sealing body 220. In one embodiment, the shape and size of the cover body 210 are adapted to the shape and size of the opening 140 to ensure that the cover body 210 can completely cover the opening 140. The shape and size of the cover body 210 and the opening 140 can be flexibly set according to the actual situation, and there is no limitation here.
[0033] Thus, when the battery needs to be replaced, simply remove the cover 200, that is, separate the flexible sealing body 220 from the opening 140, and the battery can be replaced. After replacing the battery, simply reinstall the cover 200 into the opening 140, so that the flexible sealing body 220 and the opening 140 are interference fit and the cover body 210 is in close contact with the housing 100, and the wireless earphone can be used normally. The operation is simple.
[0034] The technical solution of this utility model involves a wireless earphone comprising a housing 100, a battery unit 300, and a cover 200. The housing 100 has a receiving cavity and an opening 140 communicating with the receiving cavity; the battery unit 300 is disposed in the receiving cavity; the cover 200 is detachably disposed in the opening 140, and the cover 200 includes a cover body 210 and a flexible sealing body 220. The flexible sealing body 220 is disposed circumferentially along the cover body 210, and the flexible sealing body 220 can deform radially along the housing 100 to be detachably disposed in the opening 140 and to be interference-fitted with the opening 140. Compared to existing wireless earphones where the cover 200 and housing 100 are fixedly connected, the present invention makes the housing 100 and cover 200 detachable. The cover 200 is provided with a cover body 210 and a flexible sealing body 220. The flexible sealing body 220 and the opening 140 are interference-fitted to achieve quick assembly and disassembly of the housing 100 and cover 200, thereby enabling quick battery replacement. This solves the problem of difficult battery replacement in wireless earphones and improves the ease of use of wireless earphones.
[0035] In one embodiment, the hardness of the cover body 210 is greater than the hardness of the flexible seal 220.
[0036] Specifically, in one embodiment, the flexible sealing body 220 has good elasticity and sealing resistance, while the cover body 210 has high hardness and wear resistance. The flexible sealing body 220 can be made of materials such as rubber, silicone, or thermoplastic polyurethane, and the cover body 210 can be made of materials such as polypropylene, polyethylene, or polycarbonate. The specific materials of the cover body 210 and the flexible sealing body 220 are not limited here. Further, in one embodiment, the cover body 210 and the flexible sealing body 220 are integrally molded using two-color injection molding to ensure a tight connection between them. Of course, in other embodiments, the cover body 210 and the flexible sealing body 220 can also be integrally molded through processes such as tandem injection molding, hot melt bonding, or lamination. The integral molding process is not limited here.
[0037] Please see Figure 2 and Figure 3 In one embodiment, the cover body 210 includes a covering portion 211 and an annular portion 212. The annular portion 212 protrudes from the surface of the covering portion 211 facing the opening 140. A flexible sealing body 220 is disposed on the outer periphery of the annular portion 212, and the annular portion 212 cooperates with the inner wall of the opening 140 to clamp the flexible sealing body 220. Further, in one embodiment, the outer periphery of the flexible sealing body 220 is provided with threads to better contact the inner wall of the opening 140 and facilitate assembly. Of course, in other embodiments, the flexible sealing body 220 may also be provided with protrusions, and the inner wall of the opening 140 may be provided with corresponding grooves. Here, no specific limitation is made on the flexible sealing body 220.
[0038] The technical solution of this utility model embodiment provides support for the flexible sealing body 220 by providing an annular portion 212 on the cover body 210, further ensuring close contact between the flexible sealing body 220 and the inner wall of the opening 140, and further improving the sealing performance of the cover body 200. The hardness of the cover body 210 is greater than that of the flexible sealing body 220, so as to ensure the deformation capability of the flexible sealing body 220 while ensuring that the cover body 210 can protect the battery unit 300. The cover body 210 and the flexible sealing body 220 are integrally molded with dual-color injection molding, which ensures the aesthetics of the wireless earphone, simplifies the assembly process, ensures a tight connection between the cover body 210 and the flexible sealing body 220, improves the sealing effect of the cover body 200, further avoids contamination and damage to the battery unit 300, and improves the safety of the wireless earphone.
[0039] Please see Figure 1 and Figure 2 In one embodiment, the housing 100 is provided with an operation notch 150, which extends from the inner wall of the opening 140 to the outer wall of the housing 100 to expose a portion of the flexible seal 220. The axial thickness of the flexible seal 220 along the housing 100 is greater than the axial thickness of the operation notch 150 along the housing 100.
[0040] In one embodiment, the axial thickness of the operating notch 150 along the housing 100 is the same as the axial thickness of the cover portion 211 along the housing 100. When an external force is applied to the cover portion 211 at the operating notch 150, the cover portion 211 will be lifted, facilitating the removal of the cover 200 from the opening 140 for convenient battery replacement. In another embodiment, the axial thickness of the operating notch 150 along the housing 100 is greater than the axial thickness of the cover portion 211 along the housing 100, but less than the axial thickness of the flexible sealing body 220 along the housing 100, to ensure the sealing and firmness of the cover 200 when covering the opening 140, thus ensuring the sealing function of the cover 200. The thicknesses of the operating notch 150, the cover portion 211, and the flexible sealing body 220 can all be flexibly set according to actual needs, and are not limited here. In one embodiment, there is only one operating notch 150. Of course, in other embodiments, there may be multiple operating notches 150, and this is not limited here. Thus, by setting the operation notch 150, the ease of disassembling the cover 200 is improved, thereby improving the ease of use of the wireless headphones.
[0041] Please see Figure 2 In one embodiment, the wireless earphone further includes a main control unit 410 and a first conductive spring 420, the first conductive spring 420 being connected to the main control unit 410 and the battery unit 300.
[0042] The main control unit 410 is used to control the power on / off and functions of the wireless earphone. In one embodiment, the housing cavity includes a battery cavity and a main control cavity that are independent of each other. The battery unit 300 is disposed in the battery cavity, and the main control unit 410 is disposed in the main control cavity. The opening 140 communicates with the battery cavity for easy battery replacement. In one embodiment, the main control cavity is disposed in part of the middle shell 120 and the rear shell 130, and the battery cavity is disposed in the front shell 110 and part of the middle shell 120. In one embodiment, the wireless earphone also includes an output unit, which is disposed in the rear shell 130 and connected to the main control unit 410. The main control unit 410 can control the output unit. The output unit can be a planar diaphragm drive structure or a dynamic coil drive structure, etc., and is not limited here. In one embodiment, the rear shell 130 has an outer cover 600 on the side opposite to the front shell 110. The outer cover 600 covers the output unit for noise reduction and protection of the output unit. The outer cover 600 can be a soft shell or a mesh cover, etc., and is not limited here. In one embodiment, the main control unit 410 includes a main circuit board, with one end of the first conductive spring 420 disposed on the main circuit board and the other end exposed in the battery cavity for contact with the battery. Of course, in other embodiments, the main control unit 410 may also include multiple main circuit boards, all electrically connected; the main control unit 410 is not limited here. In one embodiment, one cylindrical battery is in contact with two first conductive springs 420 simultaneously. Of course, in other embodiments, one cylindrical battery may be in contact with only one first conductive spring 420; the number of first conductive springs 420 is not limited here.
[0043] The technical solution of this utility model embodiment, by setting a first conductive spring 420 in the main control unit 410, when installing the battery, simply put the battery into the receiving cavity and ensure that the conductive surface of the battery is in contact with the first conductive spring 420 to achieve precise conduction between the battery unit 300 and the main control unit 410; when removing the battery, simply open the cover 200 and tilt the battery to complete the removal, which is simple to operate and improves the efficiency and convenience of replacing wireless earphone batteries.
[0044] Please see Figure 2 and Figure 3 In one embodiment, the wireless earphone further includes a touch unit, which is at least partially disposed on the cover 200 and connected to the main control unit 410.
[0045] In one embodiment, the touch unit includes a flexible circuit board 510 and a second conductive spring 520. The flexible circuit board 510 is disposed on the cover 200, and the second conductive spring 520 is disposed within the receiving cavity. The second conductive spring 520 connects the main control unit 410 and the flexible circuit board 510. The flexible circuit board 510 can sense touch and convert it into a digital signal. The flexible circuit board 510 can transmit the digital signal to the main control unit 410 through the second conductive spring 520 to control the wireless earphone. In one embodiment, the annular portion 212 forms a groove, and the flexible circuit board 510 is disposed within the groove and tightly fitted to the cover portion 211. In one embodiment, one end of the second conductive spring 520 is disposed on the main circuit board, and the other end of the second conductive spring 520 is exposed in the battery cavity to facilitate contact with the flexible circuit board 510. In one embodiment, the cover 200 has an extension 230 on the side facing the receiving cavity. One end of the flexible circuit board 510 covers the surface of the extension 230 to contact the second conductive spring 520, thus realizing a detachable connection between the flexible circuit board 510 and the second conductive spring 520. Of course, in other embodiments, the end of the flexible circuit board 510 covering the surface of the extension 230 may also be provided with a socket for insertion into the second conductive spring 520. Here, the detachable connection method of the flexible circuit board 510 and the second conductive spring is not limited.
[0046] The technical solution of this utility model embodiment, by setting a touch unit and placing a flexible circuit board 510 on the cover 200, allows the flexible circuit board 510 to sense the touch when the user touches the cover 200 and convert it into a digital signal to be transmitted to the main control unit 410, thereby controlling the wireless headphones and improving the intelligence of the wireless headphones. The flexible circuit board 510 is in contact with the second conductive spring 520, realizing a detachable connection between the flexible circuit board 510 and the main control unit 410, ensuring the convenience of battery replacement.
