The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0022] First Embodiment As shown in FIGS. 1 to 4, the earphone with a replaceable outer cover includes a replaceable outer cover 100 provided with a first opening 110 and a second opening 120 at the upper part, an inner cover 200 having an antenna connection surface 200a and a circuit board connection surface 200b on the opposite side. The first engaging portion 210 and the second engaging portion 220 are provided on the antenna connection surface 200a. The first engaging portion 210 is connected to the first opening 110, and the second engaging portion 220 is connected to the second opening 120, whereby the replaceable outer cover 100 is connected to the antenna connection surface 200a, an inner cover 200, an antenna 300 provided between the replaceable outer cover 100 and the inner cover 200 or on the outer surface of the replaceable outer cover 100 in a manner that avoids the first engaging portion 210 and the second engaging portion 220, and a circuit board provided on the circuit board connection surface 200b.
[0023] The antenna 300 is attached between the outer cover 100 that is replaceable with the antenna connection surface 200a of the inner cover 200, and the circuit board is attached to the circuit board connection surface 200b of the inner cover 200. That is, by attaching the antenna 300 and the circuit board in different cavities, the mechanical stress between the antenna and the circuit board can be reduced, the structural stability can be improved, and furthermore, the electromagnetic interference between the antenna and the circuit board can be avoided, the heat dissipation performance can be optimized, and the convenience of maintenance and replacement can be further improved. Between the replaceable outer cover 100 and the inner cover 200, they are fixed through the fitting of the engaging portion and the opening. Therefore, by replacing the replaceable outer cover 100, the earphone can be assembled and formed according to various usage scenarios, and furthermore, the removal of the replaceable outer cover 100 becomes easier.
[0024] The antenna 300 can be adhered to the antenna connection surface 200a of the inner cover 200 by an adhesive. When the replaceable outer cover 100 and the inner cover 200 are connected, the antenna 300 is held between the inner cover 200 and the replaceable outer cover 100. The antenna 300 can be pre-assembled together with the inner cover 200 to achieve the replacement of only the replaceable outer cover 100.
[0025] As shown in FIGS. 1 to 3, the earphone with a replaceable outer cover further includes an outer case 400. The outer case 400 is connected to the circuit board connection surface 200b, whereby the circuit board is enclosed between the outer case 400 and the inner cover 200. The side portion of the outer case 400 away from the inner cover 200 is the side portion to be inserted into the ear canal. The support structure between the outer case 400 and the inner cover 200 can use a connection method by snap fitting.
[0026] Referring to FIGS. 3 and 4, a plurality of columns 230 are provided on the circuit board connection surface 200b so as to penetrate the circuit board. The column 230 is connected to the outer case 400, whereby the circuit board is fixed between the circuit board connection surface 200b and the outer case 400. The number of the columns 230 can be plural, and the number and shape can be flexibly adjusted according to the mounting requirements of the circuit board.
[0027] As shown in FIGS. 1 and 2, the width of the replaceable outer cover 100 gradually decreases from the front side to the rear side, and the width of the inner cover 200 also gradually decreases from the front side to the rear side. Referring to FIG. 4, the rear side of the replaceable outer cover 100 protrudes from the rear side of the inner cover 200 to form a knob 100a on the rear side of the replaceable outer cover 100. A user can apply an upward force by putting a finger on the knob 100a, and the replaceable outer cover 100 can be quickly removed, facilitating the quick replacement of the replaceable outer cover 100 and the antenna 300 and the like.
[0028] As shown in FIGS. 1 to 4, the width of the replaceable outer cover 100 gradually decreases from the front side to the rear side, and the width of the inner cover 200 also gradually decreases from the front side to the rear side. For this reason, the first engaging portion 210 is disposed on the front side of the second engaging portion 220, and the width of the first engaging portion 210 is larger than the width of the second engaging portion 220. In this way, the firmness of the connection between the replaceable outer cover 100 and the inner cover 200 can be improved. The first opening 110 and the first engaging portion 210 are adapted to each other, and the second opening 120 and the second engaging portion 220 are adapted to each other, that is, the first opening 110 is disposed on the front side of the second opening 120, and the width of the first opening 110 is larger than the width of the second opening 120.
[0029] As shown in FIGS. 1 to 4, the first opening 110 penetrates through the replaceable outer cover 100, and a first stepped portion 111 is provided on the inner wall of the first opening 110. A first mooring portion 211 is provided on the front side of the first engaging portion 210. The first engaging portion 210 is provided so as to penetrate through the first opening 110, and the first mooring portion 211 abuts against the first stepped portion 111.
[0030] The first mooring portion 211 is made of an elastic material. By utilizing the elastic deformation of the first mooring portion 211, it penetrates to the upper side of the replaceable outer cover 100 while being press-fitted into the first opening 110. At this time, the first opening 110 can be restored to its original shape and abut against the first stepped portion 111, whereby the first engaging portion 210 can be engaged with the first opening 110. When the replaceable outer cover 100 is lifted upward, the first mooring portion 211 elastically deforms and disengages from the replaceable outer cover 100, thereby realizing the opening and separation between the first engaging portion 210 and the first opening 110.
[0031] Similarly, the second opening 120 penetrates through the replaceable outer cover 100, a second stepped portion is provided on the inner wall of the second opening 120, a second mooring portion 221 is provided on the rear side of the second engaging portion 220, the second engaging portion 220 is provided so as to penetrate through the second opening 120, and the second mooring portion 221 abuts against the second stepped portion. Since the engaging and disengaging methods between the second opening 120 and the second engaging portion 220 can refer to the first opening 110 and the first engaging portion 210, detailed description is omitted here.
[0032] The first mooring portion 221 can be integrally formed with the first engaging portion 210. Naturally, the second mooring portion 221 can be integrally formed with the second engaging portion 220.
[0033] As shown in FIG. 1, the first mooring part 211 is arranged on the front side of the first engaging part 210, and the second mooring part 221 is arranged on the rear side of the second engaging part 220. In this way, when the replaceable outer cover 100 is engaged with the inner cover 200, the stability after the connection of both can be improved.
[0034] As shown in FIG. 5, the antenna 300 includes an inner peripheral part 310, an outer peripheral part 320, and a radial support part 330 connected between the inner peripheral part 310 and the outer peripheral part 320. The first engaging part 110 is arranged between the inner peripheral part 310 and the outer peripheral part 320, and is also arranged between two adjacent radial support parts 330. The second engaging part 220 is arranged outside the outer peripheral part 320.
[0035] The arrangement space of the inner cover 200 is rationally utilized so that the antenna 300 is attached to the antenna connection surface 200a while avoiding the first engaging part 110 and the second engaging part 220. The antenna 300 is of a customizable type and can be applied to Bluetooth earphones. Of course, the earphones with a replaceable outer cover can be applied to wired earphones. By replacing the replaceable outer cover 100, the antenna 300, etc., earphones can be formed and applied according to various usage scenarios.
[0036] Continuing to refer to FIGS. 1 and 5, the inner cover 200 is provided with a connection hole 240. The connection hole 240 penetrates the antenna connection surface 200a and the circuit board connection surface 200b. The inner peripheral part 310 of the antenna 300 is connected to the circuit board through the connection hole 240. For example, by sequentially passing a connecting column through the inner peripheral part 310 and the connection hole 240 and connecting it to the circuit board, the connection between the antenna and the circuit board is realized. The connecting column can be connected to the connection hole 240 in a threaded manner.
[0037] Second Embodiment Referring to FIGS. 1 and 4, the earphone with a replaceable outer cover according to the second embodiment, different from the first embodiment, the antenna 300 can be adhered to the inner surface of the replaceable outer cover 100, and the outer surface of the replaceable outer cover 100 can be exposed to the outside. When the replaceable outer cover 100 is connected to the inner cover 200, the antenna 300 is held between the inner cover 200 and the replaceable outer cover 100. At this time, the antenna 300 is pre-assembled with the replaceable outer cover 100 together, and both can be exchanged integrally.
[0038] Third Embodiment Referring to FIG. 1, the earphone with a replaceable outer cover according to the third embodiment, different from the first embodiment, the antenna 300 is on the outer surface of the replaceable outer cover 100, that is, exposed to the outside of the replaceable outer cover 100. At this time, the replacement of the replaceable outer cover 100 is realized, and further the antenna 300 is separated from the circuit board.
[0039] In addition, a liquid adhesive may be provided on the surface of the antenna 300. When the liquid adhesive hardens, the antenna 300 can be fixed and the antenna 300 can also be protected.
[0040] To summarize the above, the antenna 300 is attached between the replaceable outer cover 100 and the antenna connection surface 200a of the inner cover 200. The circuit board is attached to the circuit board connection surface 200b of the inner cover 200. That is, by attaching the antenna 300 and the circuit board in different cavities, the mechanical stress between the antenna and the circuit board can be reduced, the structural stability can be improved, and furthermore, the electromagnetic interference between the antenna and the circuit board can be avoided, the heat dissipation performance can be optimized, and the convenience of maintenance and replacement can be further improved. The rear side of the replaceable outer cover 100 protrudes from the rear side of the inner cover 200, and a knob 100a is formed on the rear side of the replaceable outer cover 100. Furthermore, between the replaceable outer cover 100 and the inner cover 200, they are fixed by fitting the engaging portion and the opening portion. Therefore, it becomes easy to quickly remove the replaceable outer cover 100, and the replaceable outer cover 100 can be quickly replaced to assemble and form earphones according to different usage scenarios.
