Problems solved by technology
[0004] However, the electroacoustic transducers used in the market have the following problems: the coil bobbin used for the yoke part of the electroacoustic transducer is generally a symmetrical structure, and is fixed on the pole piece by an adhesive. Due to the channel passing through the pole piece, the pole piece vibrates in the channel. Long-term use reduces the bonding effect of the adhesive and is easy to loosen, which affects the normal use of the electroacoustic transducer and reduces the service life. At the same time, it is inconvenient to install
