  The present invention relates to a technique for attaching a vibration supply device to a musical instrument.

Conventionally, musical instruments having a resonance body including a soundboard, such as an acoustic guitar, bass, violin, ukulele, and mandolin, are known. For example, the resonance drum of a guitar is composed of a front plate, a back plate and a side plate, and a sound hole is formed on the front plate. When the strings are played, the front and back plates, which are the soundboards, vibrate, generating rich sounds.

[Configuration of vibration supply device]
FIG. 4 is a diagram illustrating a configuration of the vibration supply device, and is a view before the vibration supply device is adsorbed to the soundboard. FIG. 5 is a view after the vibration supply device is adsorbed to the soundboard.

  In the first embodiment of the present invention, an iron sheet 20 is connected to the soundboard 7 by an adhesive or the like. The iron sheet 20 may be formed in a thin and flat seal shape. In FIG. 1, one iron sheet 20 is formed in a circular shape and connected to the outer surface of the soundboard 7.

The vibration supply device 10 includes a transducer 50, a magnet 30, an amplifier 60, a rechargeable battery 65, a storage 70, a signal generation unit 80, and an operation unit 90. As illustrated in FIGS. 4 and 5, the transducer 50, the magnet 30, the amplifier 60, the rechargeable battery 65, the storage 70, the signal generation unit 80, and the operation unit 90 may be housed in one housing. The detailed configuration of the transducer 50 is as described above.

The storage 70 stores various data including music data. The signal generation unit 80 reads music data from the storage 70, generates a drive signal based on the music data, and supplies the drive signal to the amplifier. The operation unit 90 serves as a switch for controlling selection of music data to be read out by the signal generation unit 80. The amplifier 60 is driven by receiving power from the battery 65 charged by an external power source, amplifies the drive signal provided from the signal generation unit 80 and provides the amplified signal to the transducer 50, and vibrates the vibration unit 51.

At this time, the iron sheet 20 and the magnet 30 are attracted and fixed by a magnetic force. Therefore, as shown in FIG. 5, the soundboard 7 of the musical instrument to which the iron sheet 20 is connected and the vibration supply device 10 to which the magnet 30 is connected are attracted and fixed.

In this way, vibration based on the drive signal generated from the signal generation unit 80 is transmitted to the soundboard 7 of the musical instrument through the vibration member 511, and sound generation using the soundboard 7 becomes possible. In order to realize such a configuration, the iron sheet 20 and the magnet 30 are arranged at positions corresponding to each other, that is, positions where the soundboard 7 and the vibration supply device 10 of the musical instrument can be adsorbed and fixed.
