Horn processing jig and processing method thereof

Abstract

The invention provides a horn processing jig and a processing method thereof. The jig comprises a main assembly module, a diaphragm assembly module, a front cover assembly module and a magnetic circuit carrier plate; a bracket groove and a bracket top strip are arranged in the main assembly module; a diaphragm groove and a diaphragm top strip are arranged in the diaphragm assembling module; a front cover groove and a front cover top strip are arranged in the front cover assembling module; a magnetic circuit groove is formed in the lower end of the magnetic circuit carrier plate, the support groove and the diaphragm groove can be matched to form a first press-fit cavity, the support groove and the front cover groove can be matched to form a second press-fit cavity, and the front cover groove and the magnetic circuit groove can be matched to form a third press-fit cavity. According to the invention, one main assembly module is taken as a core, the bracket and the voice coil are assembledinto the main assembly module, and then other jigs operate around the main assembly module to finish the assembly of the diaphragm, the front cover and the magnetic circuit, so that the assembly linetype production and processing is realized, the processing efficiency is high, the accommodating groove does not need to be frequently replaced, and the assembly precision is improved.

Description

technical field [0001] The invention relates to the field of horns, in particular to a horn processing jig and a processing method thereof. Background technique [0002] The speaker is a very commonly used electroacoustic transducer, which can convert electrical signals into acoustic signals. The performance of the speaker has a great impact on the sound quality. The structure of the speaker is as figure 1 As shown, it includes a bracket 51, a diaphragm 52, a front cover 53, a magnetic circuit 54, and a voice coil 55. The sounding principle is: when the voice coil 55 of the speaker is fed with audio current, the voice coil 55 will produce an alternating current under the action of the current. The permanent magnet in the magnetic circuit 54 also produces a constant magnetic field with constant magnitude and direction. Since the magnitude and direction of the magnetic field generated by the voice coil 55 are constantly changing with the change of the audio current, the inte...

Problems solved by technology

Each combination process requires a different jig, and the product needs to be ejected after pressing, which leads to low processing efficiency. In addition, due to the frequent replacement of the grooves containing the product during the assembly process, assembly errors are prone to occur, and the position accuracy of the obtained product is low.
