Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

Referring to fig. 1-6, in the embodiment of the present invention, an interactive piano for a meeting place includes an outer frame 12, a main frame 3 is disposed in the outer frame 12, an extension spring 2 is disposed above the guide post screw rod 4, a key pedal 1 is disposed above the extension spring 2, and a limit block 11 is disposed in the middle of one side above the key pedal 1; a guide pillar screw rod 4 is arranged below the main frame 3, and a damping sheet is arranged in the guide pillar screw rod 4; a groove is formed in the position, corresponding to the piano keyboard pedal 1, of the main frame 3, and a hitting sound transmission device is arranged in the groove;

further, the striking sound transmission device comprises a rapping hammer bracket 7, and the rapping hammer bracket 7 is fixedly connected to the main frame 3; a piano piece rapping hammer 6 is arranged in the rapping hammer support 7, and the piano piece rapping hammer 6 is rotationally connected to the rapping hammer support 7 through a fixing screw 8; the striking sound transmission device comprises a sounding sheet 10, and the sounding sheet 10 is hung on the main frame 3; a conduction rod 5 is arranged below the piano keyboard pedal 1, and the conduction rod 5 is arranged above one end of a piano piece knocking hammer 6; and a limiting screw 9 is arranged on the rapping hammer bracket 7, and the limiting screw 9 is arranged at the right lower part of the fixing screw 8.
