Abstract

PURPOSE: To obtain a plate speaker having a flat and wide band sound pressure characteristic and excellent in directivity at a low cost by constituting a diaphragm in a plate form and forming the form into a point asymmetrical quadri- lateral or above.
CONSTITUTION: The diaphragm 10 is constituted in the plate form entirely by making an aluminium honeycomb, for instance, a core material and adhering an aluminium foil to both the external side surfaces thereof and the form is made trapezoidal. A frame for supporting the diaphragm 10 and a magnet 14 for constituting a magnetic circuit are disposed and the end of a voice coil bobbin 16 on which a voice coil is wound is adhered to the center of gravity position of the diaphragm 10. A spider 18 for supporting the voice coil bobbin 16 and a yoke 19 are disposed. Thus, the sound pressure frequency characteristic of the whole diaphragm is improved so as to neglect the influence of a divided vibration.
