Electroacoustical converter

An embodiment of the utility model provides an electroacoustical converter. This electroacoustical converter includes the shell and accepts vibration system and the magnetic circuit who fixes on the shell that vibration system includes the vibrating diaphragm and combine the voice coil loudspeaker voice coil on the vibrating diaphragm that during stretched into the magnetic gap of magnetic circuitformation, vibration system had first end and second end, first end with the second end is relative, vibration system's amplitude influence factor includes: the condition that presets below amplitudeinfluence factor that vibration quality mm, magnetic field force fa, system [coefficient of] stiffness km or vibration mechanical resistance rm, the amplitude influence factor of first end compared the second end satisfies: the km of stiffness system of system of first end is greater than the km of stiffness system of system of second end, or the power package rm that shakes of first end is greater than the power package
