An inductive electroacoustic transducer which includes a yoke, a magnetic circuit system disposing in the yoke, a vibration membrane which is driven by the magnetic circuit system, a cover coupled on one side of the yoke and it has a plurality of sound holes, and a circuit board which has a positive pole and a negative pole for importing acoustic electrical signals. The circuit board also has an inductive soldering disc and it is coupled to another side of the yoke. A portion of the yoke is connected to the inductive soldering disc with which it is conducted.

Inductive electroacoustic transducer

An earphone set includes a main device having a digital signal processor, and an earplug has an external microphone and a speaker electrically connected with the digital signal processor respectively. The external microphone converts an external sound wave into an electronic signal and transmits the electronic signal to the digital signal processor for processing. The speaker converts the electronic signal processed by the digital signal processor into a sound wave for output.

Earphone set

An earpiece device includes a housing having a sound output portion, a speaker and a microphone. The speaker disposed in the housing includes a diaphragm and a sound transmitting hole. The diaphragm is located between the sound output portion and the sound transmitting hole. The microphone is disposed in the housing and covers the sound transmitting hole. A sound wave generated within an ear canal would be received by the speaker and delivered through the sound transmitting hole to the microphone for pickup.

Earpiece device with microphone

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.
