A speaker device employing a diaphragm structure for providing high quality sound characteristics. In particular, a separate speaker unit is additionally provided so as to improve a resonator characteristic produced at the rear side of an existing speaker. As such, the rear sound arriving at an end of the resonator is dampened by the sound outputted from the additional speaker unit, thereby improving characteristics, such as clearness, total harmonic distortion, etc.

Speaker device of mobile communication terminal for outputting high quality sound

Disclosed is an apparatus for controlling power of an electronic device, controlled by a touch input. To this end, a power control apparatus for an electronic device according to a preferred embodiment of the present invention is disclosed including a touch sensor for sensing a user's touch by a user's finger or the like, and a temperature sensor for sensing a body temperature detected through the touch. Through such a touch sensor and such a temperature sensor, the power control apparatus senses the touch and body temperature of a user, and controls the power of the electronic device. As a result, even without a separate power button installed on the outside of the electronic device, it becomes possible to control the power of the electronic device.

Power control apparatus

Provided is a speaker device for a portable terminal. The speaker device includes a speaker housing which provides a mounting space for accommodating a speaker unit and a resonating space connected to the mounting space and located around the mounting space. The speaker device solves the disadvantages of a small-size speaker unit, i.e., problems in producing a sound in a bass region, thereby producing a 'live' sound. Moreover, the characteristics of a sound can be improved using the speaker housing, without addition of a separate speaker unit or addition or change of software or a circuit, thereby improving the performance of a speaker device of the portable terminal at low cost.

Speaker device for portable terminal

A method and apparatus for providing an instrument playing service in a portable terminal. In the method, an image of an instrument is projected. User finger movements on the projected instrument image are detected and sound source information corresponding to the user finger movements is read. Thereafter, an audio signal corresponding to the sound source information is output.
