Further, the front surface 200 of the front end face 301 of rest 30 and the bottom wall 20 of adjacent terminal front housing 2
Concordantly.It is convenient for direct machine-shaping that there is the terminal front housing 2 of rest 30 in this way, and convenient for filling the remaining part of receiver 3
It is assigned to rest 30.
In addition, rest 30 is equipped with mounting groove 300, mounting groove 300 along terminal front housing thickness direction T through receiver
Holder 30.Receiver 3 further includes before the magnet steel 31, sound mould 32, receiver that the thickness direction T of terminal front housing is set gradually from back to front
Lid 33 and receiver foam 34.Magnet steel 31, sound mould 32 and receiver protecgulum 33 are both secured in mounting groove 300, and magnet steel 31 and sound mould
32 interval settings.In the present embodiment, it is interference fit between magnet steel 31 and mounting groove 300.It can not only ensure magnetic in this way
Fastness, the stability of the connection of steel 31 are also convenient for realizing the dismounting of magnet steel 31.
Receiver foam 34 is fixed on receiver protecgulum 33 and outside mounting groove 300.Receiver foam 34 and receiver protecgulum 33, sound
Mould 32 surrounds and is formed with sound chamber 35.Understood in conjunction with Fig. 5, receiver foam 34 is equipped with the louver 340 being connected with sound chamber 35.
Wherein, receiver foam 34 is fixed on receiver protecgulum 33 by gluing process.Receiver protecgulum 33 and sound mould 32 pass through
Gluing process is fixed on mounting groove 300.Gluing process is taken, it is not only simple for process, and can ensure the sealing effect of sound chamber 35,
And then ensure that sound is concentrated through louver 340 and spreads out of.In alternative embodiment, receiver protecgulum 33 passes through dispensing work
Skill is fixed on mounting groove 300, alternatively, sound mould 32 is fixed on mounting groove 300 by gluing process.
As shown in Figure 3-4, receiver 3 further includes flexible connector 36.One end of flexible connector 36 is electrically connected with sound mould 32,
The other end of flexible connector 36 extends to outside the rear end face of rest 30, and (in figure not for the mainboard with mobile terminal
Show) electrical connection.And the other end of flexible connector 36 is equipped with strip protrusion (not shown).Be conducive to reduce bullet in this way
Frictional force between property connector 36 and mainboard, to improve the sound quality of receiver 3.Strip protrusion can mould punching molding and
At, thus while processing the flexible connector 36 need to only change the shape of mold, not will produce the rising of cost.In this implementation
In mode, flexible connector 36 is metal clips.
Wherein, sound mould 32 includes voice coil 320 and vibrating membrane 321, and voice coil 320 is connected to vibrating membrane 321, flexible connector 36
One end be electrically connected with voice coil 320.In use, the audio signal of mainboard is input to voice coil 320, voice coil by flexible connector 36
320 itself magnetic fields generate variation and vibrate, to drive vibrating membrane 321 vibration and sounding, sound are passed from louver 340
Go out.
Receiver 3 further includes conductive component (not shown), and conductive component is fixed on magnet steel 31 and is electrically connected with magnet steel 31,
And conductive component is electrically connected with the mainboard of mobile terminal.In the present solution, passing through conductive part between the magnet steel 31 and mainboard of receiver 3
Part is connected, and the ground connection of magnet steel 31 is realized, to reduce influence of the receiver 3 to its neighbouring radio-frequency antenna performance.In present embodiment
In, conductive component is conductive fabric.
According to the design feature of mobile terminal product radio-frequency antenna, the metal device around radio-frequency antenna needs to do at ground connection
Reason could reduce its influence to radio-frequency antenna performance.The receiver 3 of the present embodiment is grounded by the dew copper on conductive fabric and mainboard.
This conductive fabric is will pass through when receiver 3 is in running order, between the magnet steel 31 and mainboard of receiver 3 to be connected, and realizes receiver 3
The ground connection of magnet steel 31, to reduce influence of the receiver 3 to its neighbouring radio-frequency antenna performance.
