Abstract
An acoustic transducer device is provided. The device includes a body, a speaker, a microphone, and a processor. The body has a cavity, a sound exit, and a sound entrance. The cavity interflows with the sound exit and accommodates the speaker. The microphone is disposed within the body beside the speaker. The microphone interflows selectively with the cavity or the sound entrance. The processor is electrically connected to the speaker and the microphone. When the microphone interflows with the cavity, the microphone receives a sound signal generated from the cavity and transmits the sound signal to the processor for cancelling noise in the cavity. When the microphone interflows with the sound exit, the microphone receives an external sound signal and transmits the external sound signal to the processor for cancelling noise from the external.
