Abstract:
     The present invention relates to an electronic apparatus for indicating beat and correcting tone comprising a case, an indicator, a LCD display, a key press unit, a microphone, a loudspeaker and a control unit. The indicator consists of indicating points which are longitudinally arranged on the surface of the case. The LCD display and the key press unit are assembled on the faceplate of the case, the control unit directly controls the indicator to indicate beat, and then the loudspeaker outputs the sound signal indicating the beat; alternatively, the microphone receives sound signal, the sound level is judged, then the control unit controls indicator to indicate the sound level. The control unit also controls the LCD display to display the indication information. The present invention has the functions of both metronome and tone correction, it saves the cost of hardware and saves the space. It makes the use of the electronic apparatus for indicating beat and correcting tone very easy, because when the apparatus displays beat or corrects tone, the indication information is indicated in longitudinal way which is suited to the habit of people.
