Abstract
A sensor unit, which is used for detecting a vibration of an object that is supported by a stand, comprises: a sensor board having a contact area that is configured to contact a lower surface of the object; a sensor that is configured to detect a vibration of the object and is fixed to the sensor board; a bearing that is fixed to the sensor board and has a through-hole; and a base that has a shaft that is inserted in the through-hole of the bearing. An outer configuration of the through-hole of the bearing is structured to substantially correspond to an outer configuration of the shaft of the base.

A sensor unit that is configured to be used for detecting a vibration of an object that is supported by a stand, comprising:
- a sensor board having a contact area, the contact area being configured to contact a lower surface of the object when the sensor board and the object are attached to the stand;
- a sensor that is fixed to the sensor board, the sensor being configured to detect the vibration of the object when the object is struck, the sensor being configured to receive a cable through which the detected vibration is transmitted;
- a bearing that is fixed to the sensor board and has a through-hole;
- and
- a base that is configured to be detachably fixed to the stand, the base having a shaft that extends upward and is inserted in the through-hole of the bearing;
- wherein an outer configuration of the through-hole of the bearing is configured to substantially correspond to an outer configuration of the shaft of the base.
A sensor unit that is configured to be used for detecting a vibration of an object that is supported by a stand, comprising:
- a sensor board having a contact area, the contact area being configured to contact a lower surface of the object when the sensor board and the object are attached to the stand;
- a sensor that is fixed to the sensor board, the sensor being configured to detect the vibration of the object when the object is struck, the sensor being configured to receive a cable through which the detected vibration is transmitted;
- a bearing that is fixed to the sensor board and has a through-hole;
- and
- a base that is configured to be detachably fixed to the stand, the base having a shaft that extends upward and is inserted in the through-hole of the bearing;
- wherein:
- an outer configuration of the through-hole of the bearing is configured to substantially correspond to an outer configuration of the shaft of the base, and
- the bearing is made of a material that is more flexible than the sensor board.
A sensor unit that is configured to be used for detecting a vibration of an object that is supported by a stand, comprising:
- a sensor board having a protrusion and a through-hole;
- a sensor that is fixed to the sensor board, the sensor being configured to detect the vibration of the object when the object is struck, the sensor being configured to receive a cable through which the detected vibration is transmitted;
- and
- a base that is configured to be detachably fixed to the stand, the base having a shaft that extends upward and is inserted in the through-hole of the sensor board;
- wherein the protrusion has an annular shape when viewed in a plan view, and
- an upper surface of the annular shaped protrusion is configured to contact a lower surface of the object when the sensor board and the object are attached to the stand.
