Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a listening tooling for a micro speaker module. Background Art

[0002] With the popularization of mobile devices such as smart phones, the market demand for micro speaker modules is increasing continuously. A mobile device often is equipped with multiple micro speaker modules. Due to the limitation of the internal space of the mobile device, some micro speaker modules use a longer FPC to achieve electrical conduction. However, during acoustic testing, since the FPC is long and soft in hardness, when listening to sound, the FPC is prone to bend and warp, resulting in inaccurate positioning of the conduction position of the FPC. The conduction probe on the listening tooling for the micro speaker module cannot power on the FPC, so that there is no sound during the test of the micro speaker module. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a listening tooling for a micro speaker module applicable to a micro speaker module with a long FPC, which can accurately position and conduct the FPC.

[0005] A bottom plate, on which a positioning boss is provided. A positioning groove for positioning a partial area of the FPC is provided on the positioning boss. One end of the positioning groove forms a bayonet for clamping the end of the FPC. One end of the bottom plate is further provided with a support platform, and a through groove communicating with the other end of the positioning groove is provided on the support platform. The end of the through groove far from the positioning groove communicates with the peripheral wall of the bottom plate to form an outlet for the FPC to extend out;

[0006] A cover plate, one end of which is rotatably connected to the other end of the bottom plate, and the other end of the cover plate abuts against the support platform;

[0007] A conduction probe, which is arranged on the cover plate;

[0008] An elastic member, which respectively contacts the bottom plate and the cover plate to drive the other end of the cover plate to rotate in a direction away from the bottom plate.

[0009] Further, limiting protrusions are respectively arranged on two sides of the support platform, and the support platform and the two limiting protrusions form a limiting groove for limiting the other end of the cover plate.

[0010] Further, a guiding surface is arranged on the inner side of the end of the limiting protrusion far from the support platform.

[0011] Further, the guiding surface is an inclined surface or an arc surface.

[0012] Further, the cover plate is rotatably connected to the bottom plate through a rotating shaft, and the elastic member is a torsion spring sleeved on the rotating shaft.

[0036] Further, the guiding surface 131 is an inclined surface or a curved surface.

[0037] As can be seen from the above description, the specific type of the guiding surface 131 can be selected according to actual needs.

[0038] Further, the cover plate 2 and the bottom plate 1 are rotatably connected through a rotating shaft, and the elastic member 4 is a torsion spring sleeved on the rotating shaft.
