Title: Speaker system by electronic controlling
Inventor: TAKAHASHI KENICHI
IPC: H04R3/04
Filed: 1981-05-29
Abstract: PURPOSE:To extend the low tone reproducing band without giving any effect on a signal system, by coupling the 2nd speaker at the rear part of a speaker for signal reproduction with an acoustic coupler, and feeding back the detecting signal of an acoustic coupler internal sound pressure to the 2nd speaker. CONSTITUTION:Speakers 1 and 2 are coupled with an acoustic coupler 3, and the speaker 2 is closed with a hermetically sealed box 6. When an audio signal is applied to the speaker 1, the sound pressure in the coupler 3 tends to change. This sound pressure is detected with a microphone 4 located in the coupler 3 and fed back to the speaker 2 via an amplifier 5. The speaker 2 vibrates to keep the internal sound pressure of the coupler 3 to zero. Thus, the impedance viewing the coupler 3 from the speaker 1 is zero and the speaker 1 makes vibration as if it were contained in a cabinet having an infinite volume.
