Title:
音響出力装置
Document Type and Number:
Japanese Patent JP7264052
Kind Code:
B2
Abstract:
The problem to be solved is to improve a noise cancelling function.A detection microphone, a speaker, and a housing are included. The detection microphone detects noise and has an input vibrating plate. The speaker has an output vibrating plate. The housing accommodates at least the speaker and the detection microphone therein. The input vibrating plate and the output vibrating plate are disposed approximately in the same orientation. This ensures that a sound is output from the speaker while a sound is input to the detection microphone with the input vibrating plate and the output vibrating plate facing each other, thus making it possible to bring the input vibrating plate and the output vibrating plate closer to each other. As a result, it is less likely for a phase lag to take place between the sound output from the speaker and the sound input to the detection microphone, thus providing higher noise detection accuracy of the detection microphone and contributing to an improved noise cancelling function.
