Therefore, the piano panel 102 is no longer suppressed and shaken freely. Although the shock wave received from the strings of the acoustic guitar pickup bar is weakened, the shock wave of the piano panel 102 which can be obtained when the present invention is not assembled, and the piano are obtained. The resonance and tone of the box itself; and the accidental creation of a special tone ~ overtone, making the tone become many levels.

In addition, when an electric guitar pickup is used for plugging in, the electric guitar pickup is powered by a metal string, and the magnetic field of the magnet on the pickup and the coil, generating electric power to transmit a signal, and the faster the string vibration speed, the stronger the electric power signal is. The higher the string frequency, the higher the audio; and the player pulls the actuating lever 3 provided in the resonance box 101, The top member 31 of the actuating lever 3 is slidably disposed in the insertion space 5 between the fixed plate 1 and the movable plate 2, so that the movable plate 2 is pushed by the top member 31 against the top plate 102 to When the player is plucking the strings; since the piano panel 102 is pressed against the top of the movable panel 2 to suppress the vibration of the piano panel 102, the piano panel 102 is pressed and no longer absorbs the shock energy of the strings, so that the pickup can be effectively received. The string shock energy is obtained to obtain a longer extension sound; however, when the player returns the actuator 3 to the initial state, the top member 31 of the actuator 3 is slid away from the fixed plate 1 and the movable plate. The insertion space 5 between the two is such that the movable panel 2 is no longer pushed by the top jaw 31 of the actuating lever 3 to release the abutment of the piano panel 102, so that the piano panel 102 is no longer restrained and free to vibrate. The piano panel 102 absorbs the vibration energy of the strings, shortening the continuous shock wave and shortening the sound, but obtains the resonance sound of the piano panel 102 and the resonance box 101; and unexpectedly creates a special tone to overtone, which makes the tone become many layers.

Moreover, in the case of a general acoustic guitar, when the strings are stretched for a long time, the surface of the piano is easily deformed, resulting in a disadvantage that the distance between the strings and the fingerboards becomes high, which may cause a change in tone color and deviation of the pitch; The movable panel 2 is pushed by the top jaw 31 to abut against the top panel 102, and the deformation of the piano panel 102 is suppressed, so that the panel deformation probability is greatly reduced, which is an additional benefit of the present invention.
