Electronic beat sound-calibrator and control method

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.

Description

technical field [0001] The present invention relates to an electronic sound device and its control method, in particular to an electronic beat tuner with both functions of a metronome and a tuner, and controlling the electronic beat tuner to complete the beat demonstration and tune function Methods. Background technique [0002] Metronome and tuner are widely used in music teaching, instrument practice and other music practice. Learning music and musical instruments is inseparable from training and mastering accurate beats. A metronome has always been an essential tool for learning music and musical instruments; Accuracy will affect the judgment of the sound level and the sense of music, so before practicing, you must use a tuner to tune the instrument you are learning and playing. [0003] With the development of modern electronic technology, music creation, performance and music teaching have more and higher requirements for the enrichment and improvement of the sound an...

Problems solved by technology

[0003] With the development of modern electronic technology, music creation, performance and music teaching have more and higher requirements for the enrichment and improvement of the sound and rhythm of music works. The traditional mechanical or analog mechanical metronome and a single twelve-average However, the existing electronic metronome and electronic tuner only have beat demo or electronic tuner. The function of tuning, the function is relatively single, which is not conducive to reducing costs. If there is an electronic beat tuner that has two functions of beat demonstration or tuning, and organically combines the beat demonstration indicator and the tune demonstration indicator , it can be achieved that the size and production cost are similar to those of a single-function electronic metronome or tuner. It will definitely be welcomed by users and achieve good social and economic benefits.
