JPH06186979A - Sound source using magnet as striking element - Google Patents

Abstract

PURPOSE:To obtain an unstable timbre, to enjoy the motion of the magnet, and to take an auditory and a visual interest by placing the magnet which is unfixed in optional motion by electromagnetic induction and generating a sound. CONSTITUTION:The magnet 2 is placed in a box body 1 and a coil 3 is arranged below the box body 1. An AC or intermittent current is supplied to the coil 3 and then lines 4 of magnetic force are sequentially generated from N to S and from S to N and pass through the box 1. The magnet 2 reacts to the lines 4 of magnetic force to overturn and jump by repeating repulsion and attraction, so that the magnet optionally rotates, vibrates, and jumps. At this time, the magnet 2 strikes on the internal wall of the box body 1 to generate a sound. Therefore, when the box body 1 is formed of a transparent body such as glass, the motion of the magnet 2 can be viewed. Further, the box body 1 generates a unique timbre according to a material such as glass, nonferrous metal, and plastic. Further, the size and length of the box body 1 are varied to generate a scale.

Description

DETAILED DESCRIPTION OF THE INVENTION In the present invention, a magnet that is not fixed is arbitrarily moved by electromagnetic induction to generate sound. Conventionally, there are various sound sources by electromagnetic induction, but all of them generate sound by vibrating an iron piece whose one end is fixed or semi-fixed or hitting something. In that case, a stable timbre was obtained, but it was only interesting for signal sounds, and it was lacking in interest. The present invention is not interesting to both hearing and sight, because it produces an unstable tone color and also makes the movement of the magnet interesting. This will be described with reference to the drawings. A magnet 2 is placed in a box body 1, and a coil 3 is arranged below the box body 1. Now, when an alternating current or an intermittent current is applied to the coil 3, the magnetic force line 4 becomes N-
S and S-N occur sequentially and pass through the inside of the box 1. The magnet 2 reacts to the lines of magnetic force 4 and flips or jumps so as to repeat repulsion and inquiries.
Perform a jumping exercise. At this time, the magnet 2 collides with the inner wall of the box 1 and produces a sound. Therefore, when the box body 1 is made of a transparent body such as glass, the movement of the magnet 2 can be seen and the purpose can be achieved. Further, the box body 1 can produce a unique tone color depending on the material such as glass, non-ferrous metal, plastic or the like. You can also create a scale by changing the size and length of the box 1.
It can also be a sound source as a musical instrument. The effect is the same even if part of the box body 1 is replaced by the drum membrane 5, the strings 6, the metal pieces 7, and the like.
