Vibration speaker

Abstract

A vibration speaker layout is disclosed to maximize vibration quantity as vibration member is made feasible of resonation in vertical direction by individually furnishing signal input devices for sound generation and vibration generation respectively, which layout comprises a case ; a vibration plate in order to generate sound, the outside edge of which vibration plate is adfixed to top part of case ; a voice coil wound cylindrically whose top is adfixed to vibration plate ; a vibration member composed of magnet and yoke which vibration member is furnished under voice coil , which magnet is polarized up and down into N and S poles respectively, and which yoke constitutes magnetic circuit, having been attached to the magnet; an elastic member that elastically supports between the vibration member and the case so that the vibration member may move up and down vertically; and a coil of single phase to generate vibration which coil is attached to bottom surface of the case, facing the vibration member at bottom part of the vibration member so that this coil may drive the vibration member up and down vertically by interaction with the vibration member; whence formation is so that sound be generated by oscillating vibration plate making high-frequency electric current to be applied through voice coil at time of high-frequency signal input while vibration be generated by driving vibration member up and down making low-frequency electric current to be applied through coil to generate vibration at time of low-frequency signal input.
