Abstract

A drum head includes: a first film including a striking surface; a second film disposed opposed to a back surface of the first film which is back from the striking surface; and a sensor disposed between the first film and the second film and configured to output a signal related to vibration. The sensor includes: a first contact surface configured to contact the back surface of the first film without being secured to the back surface; and a second contact surface configured to contact a front surface of the second film without being secured to the front surface. A sensor tail of the sensor is secured to at least one of the first film and the second film located outside the shell when the first film and the second film are stretched over an open end of a shell.

First claim

The invention claimed is:

1. A drum head comprising:
a first film including a striking surface and a back surface opposite the striking surface;
a second film including a front surface disposed facing the back surface of the first film; and
a sensor disposed between the first film and the second film and configured to output a signal related to vibration, and comprising:
a first contact surface in contact with the back surface of the first film without being secured or bonded to the back surface;
a second contact surface in contact with the front surface of the second film without being secured or bonded to the front surface; and
a sensor tail secured to at least one of the first film or the second film located outside a shell when the first film and the second film are stretched over an open end of the shell.

2. The drum head according to claim 1 , wherein the sensor tail is secured to the second film located outside the shell and extends through the first film toward an outside of the first film.

3. The drum head according to claim 1 , wherein the sensor tail is secured to the first film located outside the shell and extends through the second film toward an outside of the second film.
