As a kind of preferred technical scheme, described flexible circuit board locating notch is square breach.
As a kind of preferred technical scheme, in described flexible circuit board, be provided with location hole, the corresponding described location hole of described shell is provided with reference column, and described reference column and described location hole are fixed described flexible circuit board and described shell.
The utility model loud speaker module, in flexible circuit board, be provided with locating notch, by the corresponding locating piece that arranges of the relatively-stationary positioning tool of flexible circuit board and loudspeaker monomer, locating notch in flexible circuit board and the locating piece on positioning tool are fixed, when guaranteeing locating effect, when flexible circuit board and positioning tool disengaging, only positioning tool need be detached, can loudspeaker monomer voice coil leads and flexible circuit board not caused and be pullled, avoid rosin joint, improve loud speaker module reliability.
Accompanying drawing explanation
Fig. 1 is the utility model loud speaker module embodiment explosive view;
Fig. 2 is fixedly schematic diagram of loud speaker module flexible circuit board shown in Fig. 1 and speaker housings.
Embodiment
Below in conjunction with accompanying drawing, describe the utility model loud speaker module concrete structure in detail.
As shown in Figure 1, the utility model loud speaker module, comprise the first housing 11 and the second housing 12, in the shell that the first housing 11 and the second housing 12 form, accommodate and be fixed with loudspeaker monomer 2 and flexible circuit board 3, flexible circuit board 3 is electrically connected to loudspeaker monomer 2, flexible circuit board 3 inputs to the signal of telecommunication of external electronic circuits in loudspeaker monomer 2, drives loudspeaker monomer 2 sounding.
As a kind of preferred technical scheme, as shown in Figure 1, in flexible circuit board 3, locating notch 31 is set to square, corresponding with it, locating piece on positioning tool is also square structure, the locating notch 31 of square structure can make flexible circuit board 3 contact by three faces with positioning tool, improves fixing stability, guarantees welding precision.
In order to guarantee flexible circuit board 3 fixing steadiness in loud speaker module shell, as shown in Figure 1, flexible circuit board 3 is provided with location hole 32, corresponding with it, as depicted in figs. 1 and 2, on loud speaker module shell, be provided with reference column 13, reference column 13 coordinates with location hole 32, flexible circuit board is firmly fixed in loud speaker module shell, avoids flexible circuit board 3 to depart from housing, improve loud speaker module reliability.
The utility model loud speaker module, by locating notch is set in flexible circuit board, improve flexible circuit board and positioning tool locate mode, the accuracy of voice coil leads and flexible circuit board welding in raising production process, while avoiding positioning tool to depart from flexible circuit board, butt welding contact pulls, avoid consequent rosin joint, improved the reliability of loud speaker module.
These are only the utility model case study on implementation, be not limited to the utility model, as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of recording in claims.
