Abstract

An active vibratory noise control apparatus has a speaker for canceling vibratory noise in the passenger compartment of a vehicle, the speaker being used as a speaker of one of different audio devices that can be installed on the vehicle. Each of the audio devices has a command key switch assembly. When the command key switch assembly is operated to turn off the transistor, a control signal is applied to a switching control circuit in an active vibratory noise control unit, which identifies the audio device installed on the vehicle. The active vibratory noise control unit generates a canceling signal matching characteristics of the speaker of the identified audio device for canceling vibratory noise in the passenger compartment.

Description

Invention field [0001] The present invention relates to an active vibration and noise control device for supplying an audio signal output from an audio unit and a cancellation signal used to cancel vibration and noise in a vehicle compartment to a shared speaker unit, and the shared speaker unit converts the provided signal into Replay the sound. Background technique [0002] There has been proposed an active vibration noise for supplying an audio signal output from an audio unit and a cancellation signal used to cancel vibration noise in the vehicle cabin to a common speaker unit that converts the provided signal into playback sound Control device (for example, see Japanese Patent Application Laid-Open No. 6-130971). [0003] As shown in FIG. 9 of the accompanying drawings, an example of such an active vibration and noise control device has an active vibration and noise control unit 30-3, an audio unit 70, and a speaker unit 41. [0004] The audio unit 70 has a sound source devi...
