Abstract
A keyboard unit includes: a key; a plurality of members which include the key, and each of which has an engaged section for forming an engaged state, the engaged state changed by turning of the key, at least a portion of the engaged section formed of a conductor; a detector which is configured to detect information on the engaged state of the plurality of members by detecting a conduction state between the at least portions of the engaged sections which are in contact with each other; and a determiner which is configured to determine a musical sound parameter based on a detection result of the detector.
Claims20
A keyboard unit comprising:
- a key;
- a plurality of component members and a hammer, as engageable members where an engagement state of the engageable members engageable with each other is changeable in at least one of a pressing stroke or a releasing stroke of the key, the hammer being driven by the pressing stroke of the key;
- a first detector for a first set, from among the key and the engageable members, including:
- a first movable member;
- and
- a first corresponding member engageable with the first movable member,
- wherein the first movable member and the first corresponding member engage and come in contact with each other at first engagement sections thereof, and
- wherein the first detector is configured to detect the engagement state of the first movable member and the first corresponding member;
- a second detector for a second set, from among the key and the engageable members, different from the first set and including:
- a second movable member;
- and
- a second corresponding member to be engageable with the second movable member,
- wherein the second movable member and the second corresponding member engage and come in contact with each other at second engagement sections thereof, and
- wherein the second detector is configured to detect the engagement state of the second movable member and the second corresponding member;
- and
- a processor configured to implement instructions stored in a memory and perform a determining task that determines a musical sound parameter for musical sound control based on a first detection result of the first detector and a second detection result of the second detector,
- wherein at least the first engagement sections each are electrically conductive, and
- wherein the first detector detects the engagement state of the first movable member and the first corresponding member based on a state of electrical conduction between the first engagement sections.
A keyboard unit comprising:
- a key;
- a hammer;
- and
- a plurality of members, including the key and the hammer, that cause the hammer to be moved, and each having an engagement section that is engageable with another engagement section of another member, among the plurality of members, so that the engagement section and the another engagement section come into contact with each other, an engagement state thereof being changeable by a movement of the key and at least a pair of engagement sections that come into contact with each other having a conductive portion;
- a detector configured to detect the engaged state of the pair of engagement sections by detecting a conduction state between the conductive portions of the pair of the engagement sections that are in contact with each other;
- and
- a processor configured to implement instructions stored in a memory and perform a determining task that determines a musical sound parameter based on a detection result of the detector.
