Abstract

The invention discloses a disconnection-proof loudspeaker diaphragm system. The disconnection-proof loudspeaker diaphragm system comprises a voice coil bobbin, a centering support piece, a diaphragm and a dustproof cap; the voice coil bobbin is cooperated with and adhered to the centering hole of the centering support piece; the diaphragm is arranged at the outside of the voice coil bobbin in a sleeving manner and is adhered to the voice coil bobbin and the centering support piece; the dustproof cap is arranged at the diaphragm; a first convex ring and a second convex ring are arranged at the periphery of the voice coil bobbin; a first annular groove is formed in the inner wall of the centering hole of the centering support piece; a second annular groove is formed in the lower end of the diaphragm; the first annular groove of the centering support piece is cooperated with and adhered to the first convex ring of the voice coil bobbin; and the second annular groove of the diaphragm is cooperated with and adhered to the second convex ring of the voice coil bobbin. The disconnection-proof loudspeaker diaphragm system is reasonable in structure, high in connection strength, strong in centering effect and good in stability, reduces noises efficiently and is good for improving the tone quality of the loudspeaker.

Description

【Technical field】 [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker diaphragm system for preventing disconnection. 【Background technique】 [0002] Loudspeaker, also known as "horn", is a very commonly used electroacoustic transducer device, which can be seen in electronic and electrical equipment that emits sound. There are many types of speakers, but their basic working principles are similar, and they are all components that convert electrical signals into sound signals for playback. At present, the most widely used is the electric speaker, which consists of a diaphragm, a voice coil, a permanent magnet, a bracket, and the like. When the voice coil of the speaker is fed with audio current, the voice coil will generate an alternating magnetic field under the action of the current, and the permanent magnet will also generate a constant magnetic field with the same size and direction. Since the size and direction of the magn...
