Abstract
An apparatus and method are disclosed, which separates ambient noise from a voice signal in a Bluetooth headset with dual microphones, switches the connection path between the dual microphones and automatically controls output audio gain, based on the ambient noise. The method for outputting the voice signal includes receiving/comparing the first and second input signals from the first and second microphones, extracting the voice signal of substantially identical intensity from the first and second input signals, and transmitting the voice signal from the portable terminal communicating with the Bluetooth headset.
Claims42
A method for outputting a voice signal in a headset comprising the steps of:
- receiving first and second input signals from first and second microphones, respectively;
- comparing the first input signal with the second input signal received;
- extracting a voice signal of substantially identical intensity from the second and second input signals;
- and
- transmitting the extracted voice signal to a portable terminal that is communicating with the headset.
A method for outputting a voice signal in a headset comprising the steps of:
- measuring ambient noise from an input signal of a first microphone;
- changing a transmission path of the voice signal from the first microphone to a second microphone when the ambient noise is equal to or greater than a certain level;
- comparing level of the input signal of the first microphone with that of an input signal of the second microphone when the ambient noise is less than the certain level;
- and
- controlling the transmission path to be connected to a corresponding microphone, in respond to the comparison result.
A headset comprising:
- a first microphone for inputting a user's voice signal and noise signal;
- a second microphone for converting a vibration signal generated according to a user's voice event to an electrical signal and outputting it;
- and
- a controller for separating the voice signal and noise signal from input signals inputted through the first and second microphones, controlling output voce power based on the noise signal, and controlling a transmission path for voice signal between the first and second microphones.
