Abstract

The invention relates to an electroacoustic transducer. The electroacoustic transducer comprises a moving coil type transduction module and a flat plate type transduction module, The moving coil typetransduction module comprises a magnet, a voice coil and a vibration element, wherein the voice coil is arranged between magnetic poles of the magnet and is connected with the vibration element. The flat plate type transduction module comprises a frame, a vibrating diaphragm and a flat plate magnet array. The periphery of the vibrating diaphragm is fixed on the frame and is provided with a coil, and a flat magnet array is arranged on one side or two sides of the vibrating diaphragm corresponding to the coil. The low-frequency response effect of the flat plate type loudspeaker can be improved,and the depth distance of the sound field of the loudspeaker is increased, so that the sound field of the loudspeaker is effectively improved, and the spatial layering sense is improved.

Description

technical field [0001] The invention relates to the application field of loudspeaker technology, in particular to an electroacoustic transducer and a moving coil flat panel 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 dynamic speaker, including 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 diaphragm to reciprocate. The vibration of the diaphragm drives the vib...
