Abstract: Provided are an electronic cymbal and a case attachment method with which even when a case is attached to a frame, the distribution of hit sensitivity against a hit on the frame is uniform. In this electronic cymbal (1), the case (8) is attached to the frame (4) by fitting an outer peripheral hooking section (8b) of a case (8) into an outer peripheral support section (4b) of a frame (4), and fitting an inner peripheral enclosing section (8d) of the case (8) into the inner peripheral side of the frame (4). These components can be mounted without forming a screw hole in the frame (4) and screwing the case (8) and the frame (4). Thus, it is possible to suppress the stress concentration on a specific position of the frame (4) due to the screwing, and to uniformize the distribution of the hit sensitivity on the frame (4).

Abstract: Electronic percussion instruments 3a to 3g each comprise a struck surface part 30 having a dome-shaped struck surface 30a and formed into a net shape, and a ring-shaped frame 31 connected to the outer edge of the struck surface part 30, and a region on the back surface 30b side of the struck surface part 30 is open. Consequently, unlike a case where the back surface side of a struck surface is surrounded by a cylindrical shell, for example, like conventional electronic percussion instruments simulating a drum, it is possible to prevent other members from being resonant with vibrations when the struck surface 30a is hit. Therefore, hit sound can be effectively reduced.

Abstract: A frame body fixed to a membrane 10 is divided into multiple long-side frame bodies 11 and a short-side frame body aligned in a peripheral direction of a frame 3. Tension is applied to the frame body 10 by pulling each frame body 11, 12. Accordingly, it is not necessary to make the shape of each frame body 11, 12 consistent with the frame 3 (support part 30) in a complicated polygonal shape, and the shape of each frame body 11, 12 can be formed as a linear shape. Therefore, the shape of each frame body 11, 12 hardly varies. In addition, even if the shape of each frame body 11, 12 varies, tension can be uniformly applied to the membrane 10, as it is configured that each frame body 11, 12 is pulled to apply tension to the membrane 10.

Abstract: This musical sound processing device includes: a storage part that stores musical sound waveform data; a plurality of reproduction control parts that perform reproduction processes for reproducing a plurality of pieces of musical sound piece data acquired by dividing the musical sound waveform data stored in the storage part on the basis of respectively independent reproduction start timing, reproduction end timing and reproduction modes; and a mixer that mixes a plurality of reproduction sounds to be outputted as the results of the reproduction processes.

Abstract: An elastic body is attached to a percussion instrument including a body part and a head, the body part having an opening on an upper end side thereof, the head covering the opening of the body part and having attachment holes formed therein. The elastic body includes: a struck part, arranged on an upper surface of the head; insertion parts, protruding downward from the struck part; and a hook part, formed to expand from the insertion parts. In a state in which the insertion parts are inserted into the attachment holes of the head, the hook part is hooked to a lower surface of the head.

Abstract: A light sensor 19 is provided for detecting a position of a lever 14 (an intermediate position between an initial position and a terminal position of the lever 14) between an ON state and an OFF state of the lever 14, and a musical sound in accordance with the position of the lever 14 detected by the light sensor 19 is generated. That is, in each of the ON state of the lever 14, the OFF state of the lever 14, and the state where the lever 14 is therebetween, different musical sounds are generated when the head 6 is percussed. Therefore, compared with the conventional technique where musical sounds can only be generated based on the ON or OFF state of the lever 14, musical sounds of a greater variety can be generated.

Abstract: An elastic body 3 includes through holes 32 connecting upper and lower surfaces thereof. Therefore, compared with a case where the through holes 32 are not formed, a sound produced due to vibration of the elastic body 3 at a time of a percussion to the head 1 can be reduced effectively. Meanwhile, in regions where the through holes 32 are not formed, the vibration at the time of the percussion to the head 1 is propagated to the support part 20 via the elastic body 3 itself. Accordingly, the vibration at the time of the percussion to the head 1 can be propagated to the head sensor S1 via the support part 20. Accordingly, the percussion to the head 1 can be accurately detected, while the percussion sound at the time of the percussion to the head 1 can be reduced.

Abstract: A sensor for vibration detection is not installed to a second frame 301b, and an upper surface of the second frame 301b is a non-percussion surface not assumed to receive a percussion. Since the second frame 301b is elastically supported by the first frame 301a via the elastic bodies 309a to 309c, at the time of a percussion to a head 202 or a cover 206, the elastic bodies 309a to 309c can attenuate the vibration propagated from the first frame 301a to the second frame 301b. Thus, since the noise produced due to the vibration of the second frame 301b can be suppressed, the performer is allowed a favorable feeling of performance.

Abstract: An input musical sound signal is input to band pass filters, and pass musical sound signals for each sound pitch are acquired. Total level ratios based on a total of levels of a sound pitch lower than those of the pass musical sound signals are calculated from the levels that are levels of the pass musical sound signals, and output coefficients are acquired on the basis of the total level ratios. Levels of octave musical sound signals acquired by converting the pass musical sound signals into sound pitches lower than those of the pass musical sound signals by one octave are multiplied by the output coefficients. In accordance with this, the octave musical sound signals of a low sound pitch can be extracted from among the octave musical sound signals.

Abstract: Provided are a control device, a control method and a control system. In a control system, a headphone and a pedal device are in communication with each other through first communication, and the pedal device and a portable terminal are in communication with each other through second communication. Accordingly, even when the headphone can be connected to only one control device, a control instruction from the pedal device can be transmitted to the headphone through the first communication, and a control instruction from the portable terminal can be transmitted to the headphone through the second communication and the first communication.

Abstract: A speaker device includes left and right speakers and a correction part. The correction part corrects frequency characteristics of a stereo audio signal supplied to the left and right speakers so that transfer characteristics of the left and right speakers become predetermined transfer characteristics.

Abstract: There are provided an electronic musical apparatus, a storage medium storing a recording/reproduction program, and a recording/reproduction method capable of outputting a musical sound phrase and a rhythm phrase after the input musical sound phrase is output. In a case where a recording button is operated, a looper starts to record musical sounds. In this case, the musical sounds (that is, a musical sound phrase) that are being recorded are output from a speaker. Thereafter, in a case where a loop reproduction button is operated, the recording is stopped, and loop reproduction of the recorded musical sound phrase and a rhythm phrase is started. Consequently, it is possible to output musical sounds in which the musical sound phrase and the rhythm phrase are loop-reproduced after the input musical sound phrase is output.
