Problems solved by technology
However, there is a problem with the existing paper cone speakers. When the voice coil drives the paper cone to vibrate, a split vibration phenomenon will occur, that is, the vibration frequency of the middle part of the paper cone is different from that of the edge part, resulting in noise.

The invention relates to an electroacoustic transducer capable of weakening the separate vibration phenomenon. Because a magnetic circuit system and a vibration system are arranged in a shell, the electroacoustic transducer capable of weakening the separate vibration phenomenon is formed; under the magnetic action of the magnetic circuit system, the vibration spindle of the vibration system suspends in the air; furthermore, the vibration spindle is always in a steady balancing state; therefore, mechanical contact does not exist between the vibration spindle and a magnetic levitation bearing; both mechanical friction and contact abrasion do not exist between the vibration spindle and the magnetic levitation bearing; the separate vibration phenomenon can be effectively avoided; the effect of weakening separate vibration is good; and thus, good sound quality of the electroacoustic transducer can be ensured.
Description
[0001] An electroacoustic transducer capable of attenuating the split-vibration phenomenon. technical field [0002] The invention relates to an electro-acoustic transducer, in particular to an electro-acoustic transducer capable of weakening the phenomenon of partial vibration. It is suitable for the audio playback industry. Background technique [0003] There are many kinds of loudspeaker classification, among which the paper cone type is widely used, its cost is low, the circuit is simple, this kind of loudspeaker can basically achieve excellent performance, and can obtain a uniform frequency response in the mid-frequency band. However, there is a problem in the existing paper cone speaker. When the voice coil drives the paper cone to vibrate, a split vibration phenomenon will occur, that is, the vibration frequency of the middle part of the paper cone is different from that of the edge part, resulting in noise. Contents of the invention [0004] The purpose of the pre...
