Description

Technical Field

[0001] The utility model relates to the technology of mold field, in particular to a loudspeaker processing mold. Background Art

[0002] With the advancement of technology and the improvement of people's living standards, the electronic products market has developed rapidly, and consumption upgrades have prompted people to pursue high-quality audio and personalized appearance. At present, a speaker is a transducer device that converts electrical signals into sound signals. Audio electrical energy causes the speaker cone or membrane to vibrate and resonate or resonate with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to make sound. With the rapid development of speakers, people's requirements for sound are getting higher and higher. The performance of the speaker has a great impact on the sound quality. Since the speaker is the weakest device, in the production of speakers, the various components are generally assembled manually between the various processes. Since everyone's operating methods are not fixed and consistent, the sound quality of each speaker is different. At the same time, manual work is not only inefficient.

[0003] Later, a speaker assembly jig appeared on the market, which placed each component on the corresponding jig in each process and then assembled and connected them, thereby improving the production efficiency of the speaker and ensuring the stability of the speaker's sound quality. However, the existing assembly jig has a poor structural design. The voice coil needs to cut the wire on the voice coil to a certain length and then weld the wire to the copper sheet. This process is generally performed after the voice coil and the copper sheet are assembled and connected on the jig. It is difficult to manually lead out the voice coil wire, cut it to an appropriate length and weld it to the copper sheet. As a result, the subsequent quality of the speaker is unstable and a large number of defective products appear. It cannot meet the production needs of users and has a small scope of application.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
