Embodiment Construction

[0014] Below, the substantive features and advantages of the present invention will be further described in conjunction with examples, but the present invention is not limited to the listed examples.

[0015] like Figure 1 to Figure 3 As shown, the key structure of the electronic piano of this embodiment includes a base 1, a connection assembly 2, an elastic member 3 and a key 4, the connection assembly 2 is arranged on the base 1, and the key 4 is arranged on the connection assembly 2, so The elastic member 3 is connected with the key 4 and the base 1 respectively. The connection assembly 2 includes a hook 21 having an extended contact surface 211 . The key 4 includes a limiting member 41 located at the front of the key 4 , and the limiting member 41 is opposite to the hook 21 . When the key 4 is at the first position, the hook 21 is spaced from the limiting member 41 , and when the key 4 is at the second position, the limiting member 41 abuts against the lower part of the...

Abstract

The invention relates to a key structure of an electronic piano. The key structure comprises a base, a connecting assembly, an elastic piece and a key, wherein he connecting assembly is arranged on the base, the key is arranged on the connecting assembly, and the elastic piece is connected with the key and the base. The key structure is characterized in that the connecting assembly comprises a hook, the hook is provided with an abutting surface formed by extension, the key comprises a limiting piece, the limiting piece is located at the front part of the key, the limiting piece is arranged opposite to the hook, the hook and the limiting piece are spaced when the key stays at a first position, the limiting piece is abutted against the lower part of the abutting surface when the key stays at a second position, the connecting assembly comprises first supporting blocks, the first supporting blocks are located at two sides of the hook, each of the first supporting blocks comprises two end parts which are arranged at an interval, and the end parts are provided with a sinking portion therebetween. The key structure can limit the key position, and a circumstance that the key position cannot be well contacted with a induction piece after long-term use is avoided. In addition, the key and the base are convenient to be assembled, disassembled and maintained.

Description

technical field [0001] The invention relates to an electronic piano, in particular to a key structure of the electronic piano. Background technique [0002] An electronic piano is a keyboard instrument, which is actually an electronic synthesizer. It uses large-scale integrated circuits, and most of them are equipped with sound memory memory. It is used to store the real sound waveforms of various instruments and output them during performance. The user makes the electronic piano produce different sounds by pressing the keys while playing. The sound produced by the electronic piano is related to the contact between the key and the sensor. If the pressure applied by the key to the sensor changes, it will affect the sound produced. After the existing keys are played for a long time, the rotation angle of the keys will change, causing the sound to change; in addition, the key structure is complicated, and it is not easy to install, disassemble and maintain.
