A signal output device comprising a housing, a fastener that attaches the housing to an object that includes a portion to be struck, an arm section attached to the housing, an extension section extending from the arm section and configured to contact the portion to be struck, a first sensor that detects vibration transmitted to the arm section and outputs a vibration signal representing the vibration, a second sensor provided on the housing and that detects vibration transmitted to the housing, and an output terminal that outputs the vibration detected by at least one of the first sensor or the second sensor.

Signal output device

An impact detection device includes: a body configured to be struck; a vibration sensor that detects vibration of the body; a support base that supports the vibration sensor; a first elastic body sandwiched between the vibration sensor and the body; and a second elastic body sandwiched between the vibration sensor and the support base. A dimension of each of the first elastic body and the second elastic body is smaller than a dimension of the vibration sensor when viewed from an arrangement direction in which the first elastic body, the vibration sensor, and the second elastic body are arranged.

Impact detection device and percussion instrument

A percussion instrument is provided that includes a shell, a head and a speaker. The shell has a wall portion and at least one opening. The head is attached to the shell and overlies the at least one opening of the shell. The speaker is provided inside of the shell and oriented to output sound having a main direction of propagation towards the wall portion of the shell and/or the at least one opening of the shell having the head according to an input signal.

Percussion instrument

A sound pickup device includes: a housing; a mount portion via which the housing on an object constituting a portion of a musical instrument; a sound pickup including a plurality of the microphones respectively oriented in different directions; a first output configured to output a sound signal indicating a sound input to the sound pickup; and an installer configured to install the sound pickup on the housing such that each of the plurality of microphones is oriented away from the object when the housing is mounted on the object via the mount portion.

Sound pickup device and sound processing device

A sound pickup device includes: a housing; a mount portion via which the housing is mounted on an object; a sound pickup including a microphone; a first output configured to output a sound signal indicating a sound input to the sound pickup; an installer configured to install the sound pickup on the housing; a sensor configured to detect a vibration transmitted to the housing; and a second output configured to output a vibration signal indicating the vibration detected by the sensor.

A drum pad capable of providing an excellent percussion feeling and securely adhering a base portion to a body portion made of rubber. The drum pad has a rear-side clothlike material which is provided on a rear surface of the body portion and into which the rubber of the body portion is impregnated. The base portion is fixed to a rear surface of the rear-side clothlike material via a fixing layer made of pressure sensitive adhesive or adhesive and provided on the rear surface of the rear-side clothlike material.
