Specific embodiment

The utility model is further illustrated below by the mode of embodiment, but is not therefore limited in the utility model Among the embodiment described range.

Fig. 3 and Fig. 4 shows a kind of schematic structure of front shell assemblies 1 according to an embodiment of the present invention.As Fig. 3-4 institute Show, front shell assemblies 1 are used for mobile terminal.In the present embodiment, mobile terminal can be mobile phone or tablet computer etc..Front housing group Part 1 includes terminal front housing 2 and earpiece 3.In the present embodiment, the upper end of mobile terminal is arranged in (i.e. along mobile terminal in earpiece 3 Length direction upper end, and be located at the upper end of the display area of mobile terminal), earpiece 3 can be close to making when in order to answer The ear of user, sound are bigger apparent.

Wherein, earpiece 3 includes rest 30.Terminal front housing 2 has bottom wall 20 and is surrounded on the side frame 21 of bottom wall 20. Side frame 21 has the upper side wall 22 on the width direction W of terminal front housing.Have in bottom wall 20 close to the region of upper side wall 22 There is accommodating space (not shown).Accommodating space along terminal front housing thickness direction T through bottom wall 20.Rest 30 is embedding It is integrally formed set on accommodating space, and with terminal front housing 2.

Rest 30 and terminal front housing 2 are integrally formed, it is not necessary that two positioning ribs and positioning rib is additionally arranged and listens Evacuation gap between cylinder 3, this reduces the distance between the downside of earpiece 3 and the upper side wall 22 of terminal front housing 2, mobile The region covered needed for the alternatively non-transparent district of the front cover of terminal reduces so that alternatively non-transparent district front shell assemblies 1 length direction (with end Hold front housing length direction L it is parallel) on width reduce so that the black surround region on mobile terminal top reduces, improve The viewing area accounting of the front cover of mobile terminal.

Specifically, rest 30 is integrally formed by Shooting Technique and terminal front housing 2.Simple process, production cost is low, And structural strength is high.In the present embodiment, the material of rest 30 is identical as the material of terminal front housing 2.In processing, lead to Cross 30 part of rest that Shooting Technique processes earpiece 3 in terminal front housing 2.After the completion of injection molding, then by earpiece 3 other Part is assembled to the rest 30 in terminal front housing 2.

Further, the adjacent upper side wall 22 of rest 30.Downside and the terminal of earpiece 3 can be further decreased in this way The distance between upper side wall 22 of front housing 2, so that the region covered needed for the alternatively non-transparent district of the front cover of mobile terminal reduces.

Further, the front surface 200 of the bottom wall 20 of the front end face 301 of rest 30 and adjacent terminal front housing 2 Concordantly.There is the terminal front housing 2 of rest 30 convenient for direct machine-shaping in this way, and convenient for filling the remaining part of earpiece 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 earpiece Bracket 30.Earpiece 3 further includes before the magnet steel 31, sound mould 32, earpiece that the thickness direction T of terminal front housing is set gradually from back to front Lid 33 and earpiece foam 34.Magnet steel 31, sound mould 32 and earpiece front cover 33 are both secured in mounting groove 300, and magnet steel 31 and sound mould 32 interval settings.It in the present embodiment, is interference fit between magnet steel 31 and mounting groove 300.It can not only guarantee magnetic in this way Fastness, the stability of the connection of steel 31 are also convenient for realizing the dismounting of magnet steel 31.

Earpiece foam 34 is fixed on earpiece front cover 33 and is located at outside mounting groove 300.Earpiece foam 34 and earpiece front cover 33, sound Mould 32 surrounds and is formed with sound chamber 35.Understood in conjunction with Fig. 5, earpiece foam 34 is equipped with the louver 340 being connected with sound chamber 35.

Wherein, earpiece foam 34 is fixed on earpiece front cover 33 by gluing process.Earpiece front cover 33 and sound mould 32 pass through Gluing process is fixed on mounting groove 300.Gluing process is taken, not only simple process, and can guarantee the sealing effect of sound chamber 35, And then guarantee that sound is concentrated through louver 340 and spreads out of.In alternative embodiment, earpiece front cover 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, earpiece 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 earpiece 3.Strip protrusion can mould punching molding and At, thus while processing the flexible connector 36, need to only modify the shape of mold, will not generate 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 field generate variation and vibrate, thus drive vibrating membrane 321 vibration and sounding, sound are passed from louver 340 Out.

Earpiece 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 earpiece 3 Part conducting, realizes the ground connection of magnet steel 31, to reduce influence of the earpiece 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 earpiece 3 of the present embodiment is grounded by the dew copper on conductive fabric and mainboard. When earpiece 3 is in running order, it will pass through this conductive fabric between the magnet steel 31 and mainboard of earpiece 3 and be connected, realize earpiece 3 The ground connection of magnet steel 31, to reduce influence of the earpiece 3 to its neighbouring radio-frequency antenna performance.
