Abstract

PURPOSE:To increase the actual feeling of playing a musical instrument by providing vibration to the musical instrument in accordance with the music being played. CONSTITUTION:Two voice coil type vibration devices 5A and 5B are installed underneath a top board 2 which supports a keyboard 3 of an electronic piano 1. Moving members 11, which move up and down by a low frequency voice signal current outputted through a low frequency voice amplifier device 6, are provided to the voice coil type vibration devices 5A and 5B. When the moving members 11 move up and down, the members hit the top board 2 and the vibration due to this shock is transmitted to the person, who is playing the musical instrument, through the keyboard 3.

FIG. 3 is a circuit diagram showing the configuration of the low frequency audio amplifier 6. As shown in FIG. The low-frequency audio amplifier 6 is composed of a low-pass filter 14 that extracts low-frequency components in the audio signal output from the audio output section 7, and an amplifier 15 that amplifies the extracted low-frequency signal. The output is output to the coils 12 of the voice coil type exciters 5A and 5B.

The operation of the device having such a configuration is as follows. When the player plays the electronic piano 1, the audio output section 7 outputs an audio signal corresponding to the performance. The audio signal is applied to an external output device and also to a low frequency audio amplifier 6. The low-pass filter 14 in the low-frequency audio amplifier 6 extracts the low-frequency component of the audio signal, and the amplifier 15 amplifies the low-frequency signal and outputs it to the coils 12 of the voice coil type exciters 5A and 5B.

Since the coil 12 is placed in the magnetic field formed by the permanent magnet 13, when a low frequency audio signal current flows through the coil 12, a mechanical force is applied according to Fleming's law according to the strength of the current. It moves up and down together with the movable member 11. Since the top plate 2 supporting the keyboard 3 is located near the top surface of the voice coil type exciter 5A, 5B,
The movable member 11 moves upward to open the opening 1 of the casing 9.
When it protrudes from 0, it collides with the top plate 2. This impact force causes the top plate 2 to vibrate, and the vibrations are transmitted to the player via the keyboard 3.

[0013] In the above-described embodiment, voice coil type exciters 5A and 5B are used as the excitation means, but the present invention is not limited to this, and various configurations can be used. For example, as shown in the simplified diagram of FIG.
2 is wound around an iron core 20 to create a strong electromagnet according to the output of the low frequency audio signal current. A metal arm 21 rotatable about point P is provided near the iron core 20, and a weight 22 is attached to the tip of the arm 21. When the iron core 20 becomes an electromagnet, the arm 21 rotates and is drawn toward the iron core 20 by its attractive force, and the weight 22 at the tip collides with the top plate 2. The top plate 2 vibrates due to this collision force.

[Effects of the Invention] As is clear from the above description, according to the vibration excitation device for an electronic musical instrument of the present invention, the main body of the electronic musical instrument is vibrated in accordance with the low frequency signal contained in the output audio signal of the electronic musical instrument. As a result, instead of only giving the player the sound as in the conventional case, it is also possible to give the player the vibrations that are normally generated when playing a musical instrument. This allows the player to feel as if he or she is playing a real musical instrument.
