BRANCHING TUBE RESONANT SPEAKER AND SPEAKER SYSTEM

摘要

PROBLEM TO BE SOLVED: To flatten the frequency characteristic, to make the sounds of even number multiples resonate to each other and to make a listener directly hear the sound by providing a branching tube part on the peripheral side face of hollow tube body oppositely arranging a speaker or a vibrating plate at one end of aperture ends. SOLUTION: The branching tube resonant speaker 1a has an oppistely arranged speaker unit 11 inside the outer end of a branching tube part 2 whose hollow part is continued to the hollow tube body 3 and outer end is opened on the hollow tube body 3 and the peripheral side face of the hollow tube body 3 or an aperture end 7 of the hollow tube body 3. When a voice signal is supplied to a voice coil in the speaker unit 11, the com-pressional wave is generated. The compressional wave resonates in the hollow tube body 3 of the branching tube resonant speaker and is radiated in the air as acoustic wave from the aperture end 5 of the hollow tube body 3 and an aperture end 8 of the branching tube part 2 whose hollow part is continued to the end.
