The present disclosure relates to the field of mobile terminals, and in particular, to an earphone socket, a mounting structure, and a mobile terminal including the earphone socket.
When an earphone socket is installed in a mobile terminal such as a mobile phone, the mobile terminal must have enough housing space to accommodate the earphone socket. However, in related art, the housing space of the mobile terminal for the earphone socket is large, which eventually causes the entire mobile terminal to be bulky.
In order to make the technical solution described in the embodiments of the present disclosure more clearly, the drawings used for the description of the embodiments will be briefly described. Apparently, the drawings described below are only for illustration, but not for limitation. It should be understood that, one skilled in the art may acquire other drawings based on these drawings, without making any inventive work.
In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the present disclosure will be more fully understood.
It should be noted that, when an element is referred to as being “fixed” to the other element, it may be directly on the other element or a further element may be presented therebetween. When an element is considered to be “mounted”, “connected”, “coupled” to the other element, it can be directly connected to the other element or a further element may be presented therebetween. The terms “inner”, “outer”, “left”, “right”, and the like, as used herein, are for the purpose of illustration and are not intended to be the only implementation means.

The microphone resilient component 200 includes a first arc-shaped sleeve 210 and a first assembling part 220. The first arc-shaped sleeve 210 defines a cylindrical cavity 214 therein, and the side wall enclosing the cylindrical cavity 214 defines a notch 215 (referring to
The microphone resilient component 200, the right channel resilient component 300, the left channel resilient component 400, and the earthing resilient component 500 are all provided in the form of resilient trips and are all mounted on the support base 100. Such resilient trip has a thin thickness and has a certain mechanical strength. Therefore, the volume of the entire earphone socket 10 is reduced in this way, the size of the headphone jack 10 is reduced in the thickness direction of the support base 100 (i.e., the height dimension of the headphone jack 10 is reduced), and the installation space required for the earphone socket 10 is reduced. Also, the material required for the microphone resilient component 200, the right channel resilient component 300, the left channel resilient component 400 and the earthing resilient component 500 is reduced, and the production cost and material cost of the earphone socket 10 is hereby reduced. When the earphone socket 10 is installed on a mobile terminal such as a mobile phone, the total thickness of the mobile terminal can be effectively reduced, which is in line with the trend of thinning the mobile terminal.
In some embodiments, the microphone resilient component 200, the right channel resilient component 300, the left channel resilient component 400, and the earthing resilient component 500 may each be made of a stainless steel material, and the thickness of the four resilient components may range from 0.15 mm to 0.30 mm. In other embodiments, the microphone resilient component 200, the right channel resilient component 300, the left channel resilient component 400, and the earthing resilient component 500 can also be made of material such as phosphor bronze, beryllium copper, white copper (i.e., copper-nickel-zinc alloy), or red copper, etc., and can also reduce the height dimension, volume and production cost, etc. of the earphone socket 10.
In some embodiments, the thickness of the support base 100 ranges from 0.6 mm to 2 mm. For example, the support base 100 may be 0.6 mm, 1 mm, 2 mm and so on according to actual conditions. On the basis of ensuring mechanical strength, the thinner the thickness of the support base 100, the lower the height dimension and volume of the entire earphone socket 10. This further reduces the installation space required for the earphone socket 10.

The first protruding part 213 is located at a second end 212b of the first arc-shaped resilient piece 212, and the first protruding part 213 protrudes a certain distance from an inner surface of the first arc-shaped resilient piece 212. The shape of the first protruding part 213 may be a taper or the like. When the earphone plug 30 mates with the first arc-shaped sleeve 210, the first protruding part 213 abuts against the earphone plug 30 due to the resilient action of the first arc-shaped resilient piece 212, thereby functioning to transmit sound signals. The first protruding part 213 may further define a first through hole 213a, and the first through hole 213a is used for electrically connecting with an external line.
In some embodiments, the first assembling part 220 includes a plurality of first inserting pieces 221 and a plurality of first supporting lugs 222. The first inserting pieces 221 are coupled to two ends of the first arc-shaped mating body 211. One of the first supporting lugs 222 is coupled to the first end 212a of the first arc-shaped resilient piece 212, the other one of the first supporting lugs 222 is coupled to the first arc-shaped mating body 211 and corresponds to the second end 212b of the first arc-shaped resilient piece 212 such that the mentioned two first supporting lugs 222 and the second end 212b may lie in a same plane (e.g., the two centers of the mentioned two first supporting lugs 222 and the two center of the second end 212b may lie in a same plane). In other words, one first inserting piece 221 and one first supporting lug 222 are coupled to one end of the first arc-shaped sleeve 210, and another one first inserting piece 221 and another one first supporting lug 222 are coupled to another one end of the first arc-shaped sleeve 210. In some embodiments, the first inserting piece 221 can be vertically disposed, and the first supporting lug 222 can be horizontally disposed. At the same end of the first arc-shaped sleeve 210, the first inserting piece 221 is located beside the first supporting lug 222, and the first inserting piece 221 and the first supporting lug 222 can be perpendicular to each other.
The support base 100 defines a plurality of first mounting holes 111 and a plurality of first recessed grooves 112. The number of the first mounting holes 111 may be same with the number of the first inserting piece 221, and the number of the first recessed grooves 112 may be same with the number of the first supporting lug 222. In one embodiment, the number of the first mounting holes 111 is two, and the number of the first recessed grooves 112 is two. In other embodiments, the number of the first mounting holes 111 may be three, four and so on, and the number of the first recessed grooves 112 may be three, four and so on. The first inserting piece 221 is inserted into the first mounting hole 111, and the first supporting lug 222 is fixed in the first recessed groove 112. Therefore, the connection between the microphone resilient component 200 and the support base 100 is realized.

At the same end of the second arc-shaped sleeve 310, the second inserting piece 321 is located beside the second supporting lug 322, and the second inserting piece 321 and the second supporting lug 322 can be perpendicular to each other.
The support base 100 defines a plurality of second mounting holes 113 and a plurality of second recessed grooves 114. The number of the second mounting hole 113 may be same with the number of the second inserting piece 321, and the number of the second recessed groove 114 may be same with the number of the second supporting lug 322.

The third assembling part 420 includes two third inserting pieces 421, and the two third inserting pieces 421 are coupled to the circular sleeve 410. For example, the two third inserting pieces 421 may be perpendicular to each other, and the first resilient contact piece 430 is coupled to one of the third inserting pieces 421. The first resilient contact piece 430 is located in a space surrounded by the third inserting pieces 421 and the circular sleeve 410 to ensure that the first resilient contact piece 430 can abut against the earphone plug 30. Each of the two third inserting pieces 421 has a first step surface 421a. The support base 100 defines two third mounting holes 115. The third inserting piece 421 is inserted into the third mounting hole 115, and the first step surface 421a is in close contact with the first mounting surface 110. Therefore, the fixed connection between the left channel resilient component 400 and the support base 100 is achieved.

The second resilient contact piece 620 is divided into three segments; that is, the second resilient contact piece 620 includes a second arc segment 621, a second linear segment 622 and a second curved segment 623 which are sequentially connected. The second arc segment 621 is coupled to the fourth inserting piece 610, and the second linear segment 622 is coupled to the second arc segment 621. One end of the second curved segment 623 is coupled to the second linear segment 622, and the other end of the second curved segment 623 is a free end. The second curved segment 623 may be curved in a wave shape, and the second curved segment 623 is bent and provided with a protrusion 623a (for example, the protrusion 623a is a peak of the wavy second curved segment 623). The protrusion 623a is used to abut against the earphone plug 30, thereby achieving signal communication between the detection resilient component 600 and the earphone plug 30. When the earphone plug 30 and the earphone socket 10 are poorly engaged, the protrusion 623a on the second curved segment 623 and the earphone plug 30 are not in contact with each other, and an alert signal can be issued to re-adjust the cooperation of the earphone plug 30 and the earphone socket 10.
The number of the fourth inserting piece 610 is one, and the fourth inserting piece 610 has a second step surface 611. The support base 100 defines a fourth mounting hole 116. The fourth inserting piece 610 is inserted into the fourth mounting hole 116, and the second step surface 611 is in close contact with the first mounting surface 110. Therefore, the connection between the detection resilient component 600 and the support base 100 is realized.
When the detection resilient component 600 and the left channel resilient component 400 are simultaneously mounted on the support base 100, the two are disposed adjacent to each other; that is, both are located at the same end of the support base 100. The first resilient contact piece 430 is opposite to the second resilient contact piece 620 so that they can form abutting forces on the earphone plug 30 from opposite sides.
