Abstract:
An installation structure for an acoustic transducer for vibrating a vibrated body of a musical instrument in a first direction for permitting the vibrated body to generate sounds, including: the acoustic transducer having a main body and a vibrating portion that vibrates in the first direction; a support portion to be fixed to a housing of the musical instrument for supporting the main body; and a cover member fixed to the support portion for covering the acoustic transducer, wherein the support portion includes a base plate portion to be held in surface contact with the housing so as to be fixed thereto, a first fixing portion to which the main body is fixed and which supports the main body, and a second fixing portion to which the cover member is fixed, and wherein the first and second fixing portions are connected to the base plate portion independently of each other.
Abstract:
An installation structure for an acoustic transducer configured to push and pull a vibrated body and having a magnetic-path forming portion; a vibrating unit; and a connector having at least one joint portion configured to connect two members such that axes of the two members are inclined relative to each other by bending at the at least one joint portion, the at least one joint portion having an urging portion configured to generate an urging force by which a pushing-side driving portion of a first member connected to one side of the at least one joint portion urges a pushing-side driven portion of a second member connected on another side of the at least one joint portion in a pushing direction and an urging force by which a pulling-side driving portion of the first member urges a pulling-side driven portion of the second member in a pulling direction.

Abstract:
A sostenuto mechanism linked to a sostenuto pedal and a sostenuto rod of a keyboard instrument, and the keyboard instrument are provided. The sostenuto mechanism includes a fixed member configured to be fixed to at least one of a middle beam or a key bed of the keyboard instrument, a movable member movably supported by the fixed member, and a movement transmission. The movement transmission is configured to be interposed between the sostenuto pedal and the movable member to transmit movement of the sostenuto pedal to the movable member. The moveable member is movable relative to the fixed member to turn the sostenuto rod in response to depression of the sostenuto pedal.
