Description

A kind of bridging structure of motor for cell phone, loudspeaker, microphone

Technical field

The utility model is related to mobile phone manufacturing technology fields, and in particular to a kind of motor for cell phone, loudspeaker, microphone bridge joint Structure.

Background technology

As shown in Figure 1, the motor, loudspeaker and microphone on existing mobile phone are provided on the small FPC2a below mobile phone, institute It states small FPC2a to be independently of display FPC4a and be located at the back side of display FPC4a, since motor, loudspeaker and microphone are located at mobile phone Lower end, and PCB main board 1a is the upper end positioned at mobile phone, therefore the longer winding displacement FPC3a of generally use one will be equipped at present The small FPC2a of motor, loudspeaker and microphone is electrically connected with PCB main board 1a, and separately installed longer winding displacement FPC3a is not only wasted Material increases cost, and the inadequate concision and compact of overall structure after installation, and affects packaging efficiency.

Utility model content

The technical problems to be solved in the utility model is：A kind of saving material is provided, reduces overall structure after cost, installation The bridging structure of motor for cell phone, loudspeaker, microphone that concision and compact and packaging efficiency improve.

The technical solution of the utility model is：The bridging structure of a kind of motor for cell phone, loudspeaker, microphone, feature It is：Include the small FPC being connected with the side of display FPC, the small FPC, which is equipped with, is used for weld motor, loudspeaker and microphone Pad area, letter of the upper pin areas for being electrically connected with PCB main board the display FPC equipped with motor, loudspeaker and microphone Number pin is additionally provided with the bridge of the pad area and the pin area of display FPC for being electrically connected small FPC on the display FPC and small FPC Link.

With the above structure, the utility model has the following advantages：

The utility model motor for cell phone, loudspeaker, microphone bridging structure be utilized it is existing display FPC pin area, The signal pins needed for motor, loudspeaker and microphone are only increased on existing pin area, it is then close on display FPC The small FPC that setting is connected with display FPC at the position of motor, loudspeaker and microphone recycles setting in small FPC and display FPC On bridge circuit, so that it may by the pad area of small FPC with display FPC pin area be electrically connected, as long as will show drawing for FPC in this way Foot area is connected on PCB main board, you can the signal pins needed for motor, loudspeaker and microphone are electrically connected together PCB together On mainboard, packaging efficiency improves, and eliminates longer winding displacement FPC, only need to increase by a small FPC and in existing display Carried out on FPC simply design, not only save material, reduce cost and also install after terminal with compact integral structure it is compact.

Preferably, the small FPC is integrally formed with display FPC.The setting can reduce cost, reduce process, and integrated Product reliability higher after together.

Preferably, the small FPC is equipped with the bent area of reduced width close to the side of display FPC.The setting can facilitate Small FPC is folded on the position that motor, loudspeaker and microphone should be installed.

Preferably, the bent area is single layer line areas.The setting is not easy to rebound after bending can be made to be easier and bend.

Specific implementation mode

Below in conjunction with the accompanying drawings, and in conjunction with the embodiments the utility model is described further.

Embodiment：

The bridging structure of a kind of motor for cell phone, loudspeaker, microphone includes the small FPC3 being connected with the side of display FPC2, The small FPC3 is equipped with the pad area 4 for weld motor, loudspeaker and microphone, on the display FPC2 for PCB master The pin area 5 that plate 1 is electrically connected is equipped with the signal pins 6 of motor, loudspeaker and microphone, is gone back on the display FPC2 and small FPC3 Bridge circuit 7 equipped with pad area 4 and the pin area 5 of display FPC2 for being electrically connected small FPC3.

The utility model motor for cell phone, loudspeaker, microphone bridging structure be utilized it is existing display FPC2 pin area 5, the signal pins 6 needed for motor, loudspeaker and microphone are only increased on existing pin area 5, then in display FPC2 The small FPC3 that the upper setting at the position of motor, loudspeaker and microphone is connected with display FPC2, recycles and is arranged in small FPC3 With the bridge circuit 7 on display FPC2, so that it may be electrically connected the pad area 4 of small FPC3 with the pin area 5 of display FPC2, so only The pin area 5 for showing FPC2 is connected on PCB main board 1, you can together draw the signal needed for motor, loudspeaker and microphone Foot 6 is electrically connected together on PCB main board 1, and packaging efficiency improves, and eliminates longer winding displacement FPC, and it is small only need to increase by one FPC3 simultaneously carried out on existing display FPC2 simply design, not only save material, reduce cost and also install after it is whole Body is simple for structure compact.

Preferably, the small FPC3 is integrally formed with display FPC2.The setting can reduce cost, reduce process, and collect At rear product reliability higher together.

Preferably, the small FPC3 is equipped with the bent area 8 of reduced width close to the side of display FPC2.The setting can be square Just small FPC3 is folded on the position that motor, loudspeaker and microphone should be installed.
