WATERPROOF STRUCTURE FOR BUTTON AND EARPHONE FIELD OF THE DISCLOSURE

[0001] The present disclosure relates to the technical field of earphone and, more

particularly, to a waterproof structure for a button and an earphone.

BACKGROUND

[0002] With a continuous development of science, technology and social economy, in

order to meet a diversified user demand for an earphone, an earphone industry is

continuing to innovate a plurality of earphone technologies, and a TWS (True Wireless

Stereo) earphone has come into our daily life. Waterproof for a button of the TWS

earphone has always been a difficulty in a waterproof design of the TWS earphone.

Since the button may produce a pressing stroke during a usage process, it may not

achieve a waterproof purpose like a plurality of other parts of the earphone through a

plurality of sealing means including using a rubber. Currently in market, the TWS

earphone is mainly achieving a waterproof purpose by adopting a two-color molded

structure between the button and a shell. In such a design, the button and the shell are

formed integrally, thus there is no assembly gap exists, being able to achieve a

satisfactory waterproof effect. However, since a principle of the two-color molded

waterproof for the button is mainly achieved by using a soft rubber to connect a plastic

button and the shell of the earphone together, while the gap between the plastic button

and the shell of the earphone is filled with the soft rubber, and in order to ensure a touch

feeling of the button, a stroke of the soft rubber in the gap should not be too little. Thus

an external space occupied by an entire button area will increase. Since a shape of a

handle of the earphone is pretty small, an existing two-color molded waterproof structure for the button can only be applied to a top of the earphone, instead of being applied to the handle of the earphone.

[0003] .Therefore, the prior art needs to be improved and developed.

[0032] Referencing from FIG.1 to FIG.4, the present embodiment provides a

waterproof structure 100 for a button, the waterproof structure 100 for the button is

applied to an earphone 200; the waterproof structure 100 for the button comprises: a

bracket 10, the bracket 10 is applied to being arranged inside a shell 201 of the

earphone 200; an electronic micro switch 20, the electronic micro switch 20 is arranged

on the bracket 10 and connected with the bracket 10; a soft waterproof piece 30, the

soft waterproof piece 30 is arranged on the bracket 10, one end of the soft waterproof

piece 30 connects with the bracket 10, and another end of the soft waterproof piece 30

is applied to squeezing and touching an inner wall of the shell 201, and the soft

waterproof piece 30 is arranged above the electronic micro switch 20 and in contact

with the electronic micro switch 20; a button 40, the button 40 is arranged on the soft

waterproof piece 30, one end of the button 40 connects with the soft waterproof piece

, and another end of the button 40 is applied to extending out of an outer surface of

the shell 201. Optionally, one end of the soft waterproof piece 30 squeezing and

touching the bracket 10, which has a simple but solid connection method, convenient for

assembling and disassembling. Optionally, a material of the button 40 is plastic.

Optionally, a material of the soft waterproof piece 30 is a silicon rubber.

[0033] A work principle of the waterproof structure 100 for the button is as follows:

[0034] The waterproof structure 100 for the button provided by the present

embodiment, wherein is able to be applied to the earphone 200, and placed inside the

shell 201 of the earphone 200, when a user is applying a force onto the button 40

extending out of an outer surface of the shell 201, the button 40 takes the force and

moves towards a soft waterproof piece 30 arranged under the button 40, the soft

waterproof piece 30 locating at the electronic micro switch 20 takes the force, and

makes an elastic deformation towards a side of the electronic micro switch 20, before

triggering the electronic micro switch 20, and achieving turning on or off the electronic micro switch 20. When the force applied onto the button 40 is retrieved, the soft waterproof piece 30 may recover the elastic deformation at a place that the elastic deformation happens, and the button 40 may also restores to an original position. Since the bracket 10 arranged inside the shell 201 is fixed, thus when turning on or off the electronic micro switch 20, one end of the soft waterproof piece 30 may always connect to the bracket 10, and another end of the soft waterproof piece 30 may always be able to squeeze and touch the inner wall of the shell 201, while only a part of the soft waterproof piece 30 locating at a place around the electronic micro switch 20 may have the elastic deformation and restore the elastic deformation, thus the soft waterproof piece 30 may generate an excellent waterproof effect, also the waterproof structure 100 for the button may be composed by assembling a plurality of parts, and separated from the shell 201 of the earphone 200, thus it is possible to make the waterproof structure

100 for the button in a whole smaller, before being applied directly to the handle of the

earphone. It should be understood that, the waterproof structure 100 for the button in

pressing cavity 31 arranged, and the pressing rod 42 is arranged in the pressing cavity

31. Since the button body 41 connects with the pressing rod 42, the user only need to

apply a force onto the button body 41, it is possible to make a bottom of the pressing

cavity 31 applied to accommodating the pressing rod 42 have an elastic deformation

and trigger the electronic micro switch 20, before achieving turning on or off the

electronic micro switch 20. A cooperation of the pressing rod 42 and the pressing cavity

31 enables the pressing rod 42 to operate more stably during a frequent pressing stroke,

having a structure solid and reliable.

[0039] Optionally, the pressing rod 42 and the button body 41 are integrated into a

one-piece structure, making a whole structure of the button 40 more solid. Optionally,

an end of the pressing rod 42 has a chamfer arranged, which facilitates a quick and accurate connection of the pressing rod 42 into the pressing cavity 31 during an assembly.

[0040] In one embodiment, continue referencing to FIG. 3 and FIG. 4, a side of the

button body 41 close to the soft waterproof piece 30 has at least one barrier 43

than an outer size of the barrier 43. That is, a depth of the accommodation cavity 32 is

larger than a thickness of the barrier 43. Arranging the barrier 43 being able to buckle

up with the inner wall of the shell 201, prevents the button 40 from slipping out of the

pressing cavity 31 during a process of being pressed and rebounded frequently. And

the inner size of the accommodation cavity 32 larger than the outer size of the barrier 43,

is applied for the barrier 43 to generating an activity space for a displacement following

the button 40 when the button 40 is generating a displacement, while a part of the

accommodation cavity 32 having the depth larger than the thickness of the barrier 43 is

a part of the pressing stroke when turning on the electronic micro switch 20.

[0041] In one embodiment, continue referencing to FIG. 3 and FIG. 4, a side of the

electronic micro switch 20 away from the soft waterproof piece 30 has a connection
