Description

technical field [0001] The invention relates to the application field of loudspeaker technology, in particular to an electroacoustic transducer and a dynamic-coil electrostatic composite loudspeaker. Background technique [0002] At present, HiFi electroacoustic speakers can be roughly divided into flat-panel speakers, dynamic speakers and electrostatic speakers according to the driving method. [0003] The most common speaker is a moving coil speaker, which includes a vibration system composed of a voice coil and a diaphragm, a magnetic circuit system composed of a permanent magnet, an iron core post, and a magnetic splint, and an auxiliary support system. When an alternating audio current is input to the voice coil, under the constant magnetic field of the permanent magnet, according to Faraday's law and the left-hand rule, the voice coil will be subjected to an alternating driving force, which will then drive the vibrating membrane to reciprocate. The vibration of the vi...
