摘要： A sound producing apparatus includes: a plurality of sound producing members with differing oscillation frequencies; dampers each corresponding to a respective sound producing member and suppressing vibration by contacting the corresponding sound producing members; a damper operation mechanism that moves each damper, thereby controlling a state of contact of the damper with a corresponding sound producing members; a soundboard that undergoes sympathetic resonance with sound producing members; a vibrator that vibrates the soundboard; an acquisition unit configured to acquire an audio signal; a signal output unit configured to: generate a drive signal for driving the vibrator with a vibration corresponding to the acquired audio signal; and output the drive signal to the vibrator; and a damper control unit configured to drive the damper operation mechanism to change a state of contact between the sound producing members and their corresponding dampers, based on frequency distribution of acquired audio signal.

摘要： In order to be able to salvage toy pianos that have become damaged during shipping, a structure and process for manufacture of toy pianos has been developed wherein (1) stop piece (or block members) are permanently affixed to certain side forming members, allowing certain other side forming members to be non-permanently affixed thereto via connectors non-permanently anchored to said block members; (2) horizontal slits are provided near the bottom of certain side members to fit over edges of the bottom member, allowing the edges of said bottom member to firmly but non-permanently nest therein; and (3) vertical grooves are provided near ends of certain side members to fit over ends of certain other side members, allowing the ends of said certain other side members to firmly but non-permanently nest therein. These innovations each assist, and together greatly facilitate, the production of a toy piano that is solid and durable in structure while simultaneously allowing easy replacement of damaged parts. Rather than the entire piano needing to be discarded the damage part can simply be removed and a new piece put in its place.

摘要： A sonic-vibration-generating mechanism of a piano is divided into a two-segment structure made up of the sonic-vibration-generating mechanism of the upstream side A and the sonic-vibration-generating mechanism of the downstream side B, and the sonic-vibration-generating mechanism of the downstream side is placed in a layered state onto the sonic-vibration-generating mechanism of the upstream side, with a plural number of weight-supporting elements of a point-support type or a line-support type allocated in between in rows at certain uniform intervals on the support frame 19 installed in the sonic-vibration-generating mechanism of the upstream side A.

摘要： The present application discloses a pickup apparatus for a musical instrument, configured to improve sound quality of a musical instrument to a greatest possible degree, obtained by a piezoelectric element. The pickup apparatus, for the musical instrument, to be fixed to the musical instrument, includes: a disc-shaped piezoelectric element; a couple of circular members receiving interposition of the piezoelectric element therebetween; and leg portions being arranged on a surface of any one of the couple of circular members, each circular member having protrusions formed protrusively toward the other circular member in two positions along a peripheral edge of an opposite surface in a face-to-face relationship with the other circular member, the piezoelectric element being supported within an air gap formed by the protrusions between the couple of circular members in a state of the piezoelectric element being interposed between the protrusions possessed by the respective circular wood members.

摘要： The present invention relates to a piano or a grand piano with a resonance board and strings which rest on a sound bridge with two longitudinal faces. Such a sound bridge serves to transmit vibration energy which is output by the strings of the instrument to a resonance board. The invention is based on the realization that, on the one hand, the rigidity of the sound bridge must be maintained at the locations at which it is in contact with the strings and the resonance board. On the other hand, it is advantageous if the mass of the sound bridge is reduced. For this reason, according to the invention it is proposed that the sound bridge have a first cutout and a second cutout, wherein the two cutouts are arranged on the two longitudinal edges of the sound bridge which lie opposite one another.
