Abstract
Description
Technical Field
[0001] The invention relates to a motor combination device, in particular to an automatic device of an acoustic motor combination. Background Art
[0002] In the acoustic part of electronic products, after the sound is generated, it needs to be transmitted to the receiver by wire, so that the user can listen to the sound content. The size of electronic products is getting smaller and smaller, which requires the size of the receiver to be reduced accordingly, but the function of the receiver cannot be limited, and it needs to be further optimized to provide a more perfect and saturated sound quality. The generation of the sound of the receiver depends on the vibration of the diaphragm, and the vibration requires the motor to provide power. Therefore, the assembly quality of the motor is related to the quality of the receiver's sound conversion. The smaller the size of the receiver, the more difficult the motor processing is. The existing motor assembly method is manual assembly, and the manual use of a microscope to complete the processes of sleeve coils, installation of iron cores and magnetic sheets on the bracket. This assembly method is cumbersome and inefficient. In addition, due to the extremely narrow internal gap of the motor, the gaps between the assembled motor parts are uneven, and abnormal noises are easily generated during the operation of the motor.
