Sensor system and procedure for controlling sound of the accordion mainly belong to the field of audio engineering and includes elements from the field of electronics and telecommunications. It consists of a system to control sound of the accordion (1) and the sensor (2), powered from a batteries (3) which can be supplemented through circuit called power supply and charging the battery (4) which provides the mobility of equipment and long-hour operation. Sound technical problem of the accordion is solved using sensor (2) which provides information about the presence and position of the hand of musician that is playing the accordion to the system for controlling the sound of the accordion (1). Depending on the state of the sensor (2), to the output audio preamplifier (7) will be forwarded a signal from one of the microphones (11, 12, 13) or from a pair of microphones that are closest to the tone played on the accordion (15), while forwarding the audio signal from the other microphones (11, 12, 13) breaks. The device has two operating modes that can be activated by different positions of the switch at control logic circuit (6). |
