Title:
SOUND OUTPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/035304
Kind Code:
A1
Abstract:
The present invention improves a noise canceling function. The present invention comprises: a detection microphone that has an input vibration plate and detects noise; a speaker that has an output vibration plate; and a housing inside of which at least the speaker and the detection microphone are disposed. The input vibration plate and the output vibration plate have substantially the same orientation. Due to this configuration, output of speech from the speaker and input of speech to the detection microphone are performed with the input vibration plate and the output vibration plate facing each other. The distance between the input vibration plate and the output vibration plate can be reduced and phase retardation between speech output from the speaker and speech input to the detection microphone is unlikely to occur, and therefore the precision with which noise is detected by the detection microphone can be increased and a noise canceling function can be improved.
