Description

Swift coupling mechanism of fender speaker

Technical Field

Background

The piano is a keyboard instrument in Western classical music and is known as the king of the instrument. It is composed of 88 keys (52 white keys, 36 black keys) and a metal string sound board. The italian person batorolo kristoffli invented a piano in 1709.

In order to make the piano convenient to move, along with the development of science and technology, people invent the electric piano, and the electric piano is lighter than a common piano.

An electric piano is an electroacoustic musical instrument. It is a musical instrument that is popular in the early eighties to ninety years, which is emerging in the sixties and seventies of the twentieth century, to replace a piano in some occasions. The sound production principle of the electric piano is that a keyboard is used as an on-off switch to form electrophoresis, once a key is pressed down, an internal crystal oscillator starts to work to form a pulse to generate a waveform with a certain frequency, and then the waveform is amplified by a frequency divider and sent to a loudspeaker to produce sound.

When the electric piano is used in various occasions, the loudspeaker of the electric piano is required to be adjusted, for example, the loudspeaker used in a 300-person theater is different from that used in a 1000-person theater. When the loudspeaker is replaced, a time-saving connecting mechanism is needed, so that the setting time of theater equipment is reduced, and once a problem occurs in the performance process, the spare loudspeaker can be replaced quickly.
