Abstract

This invention discloses a kind of mirror vibration speaker. A characteristic is that it contains a sealed speaker body. There is an output unit on top of this speaker body and this output unit includes at least one cone hole and one diaphragm hole; the loudspeaker unit is loaded on the said cone hole and sealed; the passive radiation unit has a passive diaphragm, and it is loaded on the said diaphragm hole and sealed; the vibration direction of the loudspeaker unit is the same as the vibration direction of the passive diaphragm of the said passive radiation unit; there is another mirror unit that has mirror symmetry in the opposite direction of the said vibration direction with the said output unit, as well as the above loudspeaker unit and passive radiation unit. The cone and passive diaphragm of the loudspeaker unit for this technical plan vibrate in a mirror manner in the same direction and with the same force. The instant momentum balance between the left and right of the entire speaker body prevents the vibration of the speaker body from causing a large number of additional and irrelevant harmonic waves which will result in coloration. This technical plan thus achieves a speaker with small volume and quality sound.
