Abstract
When a beating force is applied to a beat plate having a magnet attached to the lower surface thereof, an output responsive to the strength and application speed of the beating force is produced in a sensing means comprised by a Hall element disposed below the magnet. The output is used for controlling an oscillation circuit for generating a percussion instrument sound signal and an output therefrom is converted into a percussion instrument sound by means of a speaker.
Claims7
An electronic percussion instrument comprising:
- a support plate;
- a sensing element comprising a Hall element and means fixedly locating said Hall element on said support plate;
- resilient means supported with respect to said support plate and extending laterally beyond said Hall element;
- a beat plate overlying said Hall element and movably supported by said resilient means;
- a magnet pendently secured to the underside of said beat plate near said Hall element and displaceable toward the Hall element by a beating force applied to said beat plate for causing a corresponding Hall element output;
- an oscillator means for generating a sound signal like that of a percussion instrument upon being enabled by said output of said Hall element;
- an amplifier means for amplifying an output sound signal from said oscillator means;
- a speaker for converting the amplified sound signal from said amplifier means into the sound of such a percussion instrument.
