Abstract
A kind of acoustic equipment, comprises first sensor and the second transducer.First sensor is configured to sense the first sound in the duct of user or in the tissue of user, and produces first signal of telecommunication representing the first sound.Second transducer is configured to sense the second sound in duct outside, and produces second signal of telecommunication representing the second sound.Loud speaker is communicably connected to first sensor and the second transducer.Loud speaker is configured to the selected signal of telecommunication to be converted to the 3rd sound.The selected signal of telecommunication is first signal of telecommunication, second signal of telecommunication or from the 3rd signal of telecommunication in independent source.
Description
Technical field
The application relates to the acoustic assembly be deployed in acoustic equipment.
Background technology
Employ dissimilar acoustic assembly for many years.The assembly of one type is microphone.The microphone of one type is electret microphone, and its dorsulum is charged.Diaphragm along with the sound motion entered, and utilizes the motion of membrane of backboard to create the signal of telecommunication.The microphone of another kind of type is MEMS (micro electro mechanical system) (MEMS) microphone, and wherein said backboard is not charged, but external charging is applied to diaphragm and rear plate.
Another example of acoustic assembly is loud speaker.The signal of telecommunication received from each provenance is converted to acoustic energy by loud speaker.
Above-mentioned acoustic assembly can permitted to use in eurypalynous consumer device.Such as, these acoustic equipments may be used for personal computer, cell phone or panel computer.Other example is also possible.
