Problems solved by technology

However, the digital piano has no strings, and there is no hammer moving up and down when playing, so the feel of the digital piano keyboard cannot surpass the traditional keyboard; at the same time, the voltage change signal provided by the electronic contact keyboard does not contain enough keystroke information. , the piano sound synthesized according to these voltage signals can not reach perfection

Embodiment Construction

[0017] Preferred embodiments of the present invention are described in detail as follows in conjunction with accompanying drawings:

[0018] see figure 1 , the digital piano keyboard consists of multiple keys. see figure 2 , The structure of a single key of the digital piano keyboard includes a key 1, a key counterweight 2, a key support shaft 4, a key reset reed structure 6, a key hitting sensor 5, a key support plate 7, and a key electrical signal output circuit module 3. The single key 1 of the novel digital piano keyboard has the profile of a standard piano key, and a key counterweight 2 is added at the end of the key, and a key reset reed 6 is added at the front of the key 1, so that the key has the appearance of a traditional piano key when played. Hand feeling: the key supporting shaft 4 and the key-pressing sensing sheet 5 adopting the polymer piezoelectric material polyvinylidene fluoride are arranged in the middle of the key, and the key-pressing intensity and key...

Abstract

The invention relates to a novel digital piano keyboard which comprises piano keyboards, keyboard weight counterbalance, a keyboard supporting shaft, a keyboard return reed, a keyboard clicking induction plate, a keyboard support board and a keyboard electrical signal output circuit module. Due to the keyboard weight counterbalance and the keyboard return reed which are assembled on the novel digital piano keyboard, the clicking hand feel of playing a traditional piano is maintained. With the keyboard clicking induction plate adopted, the novel digital piano keyboard provided by the inventioncan obtain more abundant signals which response keyboard clicking speed and the clicking strength compared with an existing adopted electronic contact keyboard, and the signals are output in voltage signal by a keyboard electrical signal output circuit.

Description

technical field [0001] The invention relates to a digital piano keyboard. Background technique [0002] When a traditional acoustic piano is played, the hammers connected to the keyboard keys strike the strings, causing the strings to vibrate, and the reverberation effect of the wooden soundboard is added to produce the sound of the piano. The sound change of the piano includes the change of sound quality, timbre, and volume, which are actually only determined by the change of the hammer propulsion speed at the moment the string is struck. [0003] When playing a digital piano, the electronic contact keyboard replaces the mechanical hammer; the traditional strings are replaced by timbre sampling and digital timbre recording; the soundboard of the traditional piano is replaced by high-quality amplifiers and speakers. However, the digital piano has no strings, and there is no hammer moving up and down when playing, so the feel of the digital piano keyboard cannot surpass the ...
