Abstract
The utility model discloses a piece of double-magnetic-circuit high-pitch resonance sound equipment, which comprises a housing and a magnetic core arranged inside the housing. A main magnet and a resonance driving magnet are respectively sleeved on the upper end and the lower end of the magnetic core to form two magnetic circuits. A voice coil and a resonance driving motor are further respectively sleeved on the upper end and the lower end of the magnetic core. The voice coil is fixed on a diaphragm. The resonance driving motor is used for contacting an external object. When a sound current passes through the voice coil and the resonance driving motor, the voice coil and the resonance driving motor vibrate vertically under the effects of the corresponding magnetic circuits. The voice coil can drive the diaphragm to vibrate and emit sounds. The resonance driving motor drives the external object contacting the driving motor to vibrate and emit sounds. The sounds emitted by the vibration of the diaphragm are characterized by good medium high-frequency responses. Sounds emitted by the vibration of the external object driven by the resonance driving motor are characterized by good low-frequency responses. Therefore, the double-magnetic-circuit high-pitch resonance sound equipment has good response effects in all frequency ranges including low-frequency, medium-frequency and high-frequency ranges. Furthermore, the volume of the equipment is reduced.
