Abstract
An audio signal output method and apparatus for a short-range communication enabled headset are disclosed. An audio signal of the headset can be output through an internal speaker or be transmitted to an in-vehicle speaker unit. The audio signal output method includes checking, when an audio signal is present, an operating mode of the headset, outputting, if the headset is in a normal headset mode, the audio signal through an internal speaker and transmitting, if the headset is in a frequency modulation (FM) transmission mode, the audio signal through an FM channel to an in-vehicle speaker unit for reproduction, wherein the input and output gains are adjusted based on a determined vibration levels.
Claims36
An audio signal output method for operation of a headset, comprising:
- determining by said headset an operating mode of the headset;
- outputting, if the headset is in a normal headset mode, the audio signal through an internal speaker of the headset;
- and
- transmitting from said headset, if the headset is in a frequency modulation (FM) transmission mode, the audio signal through an FM channel portion of said headset to a speaker unit which is external of said headset for reproduction.
An audio signal output method for operation of a headset, comprising:
- checking by said headset whether a frequency modulation (FM) function is activated;
- outputting, if the FM function is not activated, an audio signal of the headset through an internal speaker of said headset;
- and
- changing, if the FM function is activated, an audio output path to an FM transmitter portion of said headset, and transmitting the audio signal through the FM transmitter using an FM channel.
An audio signal output method for operation of a short-range communication headset, comprising:
- receiving by said headset an audio signal from a mobile terminal through a short-range communication protocol;
- detecting by said headset a mode change event during audio signal reception;
- changing an audio output path of said headset according to the detected mode change event, the changing step comprises setting, upon mode switching to a normal headset mode, the audio output path to an internal speaker;
- and setting, upon mode switching to a frequency modulation (FM) transmission mode, the audio output path to an FM transmitter;
- and
- sending the received audio signal through an FM channel portion of said head set to a speaker which is external of said headset for reproduction.
An audio signal output method for a short-range communication headset, comprising:
- switching, in response to detection of a first event during a normal headset mode, an operating mode of said headset from the normal headset mode to a frequency modulation (FM) transmission mode;
- switching, in response to detection of a second event during the FM transmission mode, the operating mode of said headset from the FM transmission mode to the normal headset mode;
- outputting an audio signal through an internal speaker of said headset in the normal headset mode;
- and
- transmitting an audio signal to an audio system that is external from said headset through an FM channel in the FM transmission mode.
An audio signal output apparatus for a short-range communication headset, comprising:
- a memory unit for storing an application program for changing an audio output path according to an operating mode of the headset, setting information associated with at least one application program, and a mapping table for mapping between movement levels and gain values;
- an input unit for inputting a key signal for controlling the headset, and a mode change event;
- a frequency modulation (FM) transmitter for transmitting an audio signal through an FM channel to an external audio system;
- an audio processor for processing an audio signal, and sending the processed audio signal to an internal speaker or to the FM transmitter depending upon the operating mode of the headset;
- and
- a control unit for controlling the switching of the operating mode and changing of the audio output path according to the headset operating mode.
