Problems solved by technology

At present, the speaker or receiver voice coils used in mobile terminals are made of enameled wire with self-adhesive layer. , operating errors and other factors cause deformation, such as concave voice coil or outer drum
When assembling speakers or receivers, the speaker or receiver vibration components will have poor concentricity due to the deformation of the voice coil, resulting in bad performance such as speaker or receiver vibration rubbing, noise, and even disconnection and open circuit after long-term work.
[0003] In the existing speaker or receiver assembly process, the voice coil positioning tool can only position the voice coil, but cannot change the deformation of the voice coil, resulting in poor acoustic performance of the assembled speaker or receiver

Embodiment 1

[0047] Please refer to Figure 1 to Figure 5, Embodiment 1 of the present invention is: a voice coil positioning and correcting tool, which is used for positioning and correcting the voice coil 1 during the assembly process of a loudspeaker or a receiver. The tool for positioning and correcting the voice coil includes a main positioning piece 2, a secondary positioning piece and a correction device 3. The cooperation between the main positioning piece 2 and the secondary positioning piece can accurately position the voice coil 1, and the correction device 3 can be positioned on the voice coil 1 After positioning, the voice coil 1 is rectified, so that the inner concave or outer drum part of the voice coil 1 returns to the normal state. The positioning method of the voice coil 1 can be internal positioning or external positioning. The main positioning member 2 is provided with a slot 21 matching the shape of the voice coil 1 . In some embodiments, when the voice coil 1 is pos...

Embodiment 2

[0051] Embodiment 2 of the present invention is: a loudspeaker or receiver vibration component assembly process, including the following steps,

[0052] S1, pull the elastic member 32 of the rectification device 3 through the latch 34, make the rectification sheet 31 away from the slot 21 on the main positioning member 2, and insert the latch 34 into the slot 22 on the main positioning member 2;

[0053] S2. Insert the voice coil 1 into the slot 21 of the main positioning part 2;

[0054] S3, install the pot frame on the main positioning part 2, and spot weld the voice coil 1 and the pot frame;

[0055] S4. Pull out the pin 34 from the slot 22, tighten the elastic member 32 and drive the correction piece 31 to squeeze the voice coil 1, and correct the voice coil 1;

[0056] S5, bonding the basin frame, the voice coil 1 and the sound film to form a loudspeaker or receiver vibration assembly;

[0057] S6. Pull apart the elastic member 32 of the correction device 3 again, and t...

Abstract

The invention discloses a voice coil locating and correcting fixture which comprises a main locating piece and a correcting device, wherein an open groove matched with the shape of a voice coil is formed in the main locating piece; the correcting device is arranged on the side edge of the open groove; the correcting device comprises a correcting sheet and an elastic piece; one end of the elastic piece is connected to the correcting sheet; the other end of the elastic piece is connected to the main locating piece. The voice coil locating and correcting fixture integrates two procedures of assembling locating and correcting, so that high performance of a loudspeaker or a telephone receiver can be guaranteed; furthermore, the two procedures are completed in one fixture, so that the operation is facilitated, and the efficiency is relatively high.

Description

technical field [0001] The invention relates to the technical field of loudspeaker or receiver production, in particular to a voice coil positioning correction tool and a vibration assembly assembly process. Background technique [0002] Speakers or receivers are widely used in mobile terminals such as mobile phones, notebooks, telephones, and tablet computers due to their small size and light weight. At present, the speaker or receiver voice coils used in mobile terminals are made of enameled wire with self-adhesive layer. Deformation due to factors such as operating errors, such as concave voice coils or outer drums. When assembling speakers or receivers, the speaker or receiver vibration components will have poor concentricity due to the deformation of the voice coil, resulting in bad performance such as speaker or receiver vibration rubbing, noise, and even disconnection and open circuit after long-term work. [0003] In the existing speaker or receiver assembly proces...
