A headset assembly with a recording function for communication includes a left earphone, a right earphone, a call module, and a recording module. The left and the right earphones respectively have a speaker and a microphone. The call module is electrically connected to the left or the right earphone. The recording module is electrically connected to the left and the right earphones. In a first operation mode, the call module communicates with an external communication device through the microphone and the speaker of the left or the right earphone. In a second operation mode, the recording module receives an ambient sound signal through the microphones simultaneously, and records and stores the ambient sound signal. As the microphones are placed in a left auricle and a right auricle, recorded sound may have an effect of a head-related transfer function (HRTF), thus achieving an effect of a stereo sound field during playback.

Headset assembly with recording function for communication

A headphone having a headband and two acoustic transducers disposed at two ends of the headband is disclosed. Each acoustic transducer includes a baffle plate installed with a speaker, a spacer, a vent and an acoustic modulator. The baffle plate and speaker divide the acoustic transducer into a front and a back chamber. The front chamber is configured for communicating with a user's ear. The spacer is disposed behind the speaker to divide the back chamber into a first back chamber and a second back communicated with each other. The vent is disposed in a back wall of the acoustic transducer to communicate the first back chamber with outside. The first acoustic modulator is disposed between the front and second back chambers. The headphone modulates resonance frequency at low frequency bands through the acoustic modulator.

Headphone with acoustic modulator

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.
