Embodiment 1

[0040] Such as figure 1 , 2, 3, the present embodiment includes a piano body 1, a microphone 2 is placed at the position facing the keys 11 on the piano body 1, the microphone 2 can be used to collect the sound of the keys 11, and convert the collected sound into corresponding audio signal; a control unit 3 is also installed inside the piano body 1, and the control unit 3 is a single-chip microcomputer, and the control unit 3 generates corresponding control signals according to the collected audio signal; A visual output unit electrically connected to the control unit 3, the visual output unit has at least 17 telescopic members 4, each telescopic member 4 includes a display panel 41, and is controlled by a control signal and used to drive the display panel 41 to move along a straight line The driving mechanism 42, the driving mechanism 42 includes a coil 421 and a magnetic rod 422 inserted in the coil 421, one end of the magnetic rod 422 is linked with the display panel 41, a...

Embodiment 2

[0054] The drive mechanism in the telescopic member 4 can be a hydraulic cylinder, the piston rod of which is fixed to the display panel 41, and the hydraulic cylinder is controlled by a control signal. The extension speed and events of the piston rod on the hydraulic cylinder are controlled by the control signal of the control unit 3 , thereby controlling the speed and amplitude of the linear movement of the display panel 41 on the piston rod, thereby making the display panel 41 produce different visual effects. The response speed and control effect of the hydraulic cylinder are better than the cooperation of the coil 421 and the magnetic rod 422, so it can be used as the preferred option of the present invention.

Embodiment 3

[0056] Such as Figure 7 , 8 As shown, the present embodiment includes a piano body 1, and a FlexiForce pressure sensor 6 for sensing whether the keys 11 are pressed is provided below the keys 11 on the piano body 1. The pressure sensor 6 has the characteristics of softness, flexibility, and pressure sensitivity. It will not cause any feeling different from that of traditional piano playing when the user plays. The number of pressure sensors 6 is consistent with the keys 11, and is installed below the keys 11. When the keys 11 are played, the pressure sensors 6 can sense corresponding pressure signals in time; the pressure sensors 6 and the control unit 3 Electrically connected, the control unit 3 receives the pressure signal and generates a corresponding control signal; the generated control signal is the same as in Embodiment 1, and is also used to control the shape change of the visual output unit with the same structure.

Abstract

The invention discloses a piano with a sound interaction function. The piano comprises a piano body, a sound input unit used for collecting sound generated by keys of the piano and converting the sound into corresponding sound signals, a control unit used for receiving the sound signals and generating corresponding control signals, and a visual output unit realizing shape transformation according to the control signals, wherein the visual output unit is composed of a plurality of extensible members comprising display panels and drive mechanisms controlled by the control signals and used for driving the display panels to move along the line. According to the piano disclosed by the invention, sound generated by the keys of the piano is collected by the sound input unit, the shape transformation of the extensible members in different sound ranges is achieved under the control of the control unit according to the levels of the voice frequency of the collected sound; an observer can feel the change of the voice frequency visually by vision, the visual perception is good in intuition, the impact effect is stronger, the impression is deep, and the piano particular has an excellent assisted educational effect on cultivating musicality of music beginners or deaf people.

Description

technical field [0001] The invention relates to a piano, in particular to a piano with sound interaction function. Background technique [0002] The traditional piano uses the keys on the keyboard to move the small mallet covered with felt inside the piano, and then strikes the steel strings to produce sound. With the development of electronic technology, electronic pianos have also emerged as the times require. Although the sound quality is still difficult to match with traditional pianos, it is more than enough for teaching and practice. [0003] At present, with the continuous progress of modern technology, more and more interactive products appear in people's lives, and products with sound interactive technology are also more and more accepted and experienced by people. Among them, voice interaction has become a hot topic in the world. Many researchers have been unremittingly exploring the impact of voice interaction on people, especially synaesthesia research is emergi...
