Abstract: Multi tonal cymbals are provided having a metallic structure, the structure having a plurality of radial cuts therein defining a plurality of segments, each of the plurality of segments providing a tone different than another of the plurality of segments. The different tone may be achieved with radial cuts having different dimensions and/or placed on different locations on the cymbal to create different shaped/sized segments.

Abstract: A practice musical instrument configured to mimic implement rebound produced when playing a conventional version of the musical instrument can include a plurality of spaced-apart, rectangular keys. At least two of the keys can have a different length. A strike pad can be attached to a top surface of each key. Each strike pad can be formed of rubber. Each strike pad can be sized to the key to which it is attached. Hitting one of the strike pads with an implement can produce a rebound of the implement that mimics a rebound of the implement when hitting a corresponding key of the conventional version of the instrument. Hitting one of the strike pads with the implement produces a sound that is quieter than when the implement hits a corresponding key of the conventional version of the instrument.

Abstract: The invention concerns a method for adjusting the vibration frequency range of a sound producing device with vibrating tongues. The device includes an assembly formed of a comb extended by at least one vibrating tongue, said comb having at least one hole for the securing thereof to a support by means of a support jaw and of a tightening element traversing the support jaw and the hole in the aforecited comb. According to the method, the frequency range is adjusted by reducing the free length of the vibrating tongue or tongues by the localised clamping of said tongues between the support jaw and a local counter-support.

Abstract: A clapper for a bell is hollow on the inside for receiving objects, such as a personal dedication. The clapper may also be provided with a coating for damping the volume of the bell strike, or at least change the sound.

Abstract: There is provided a performance apparatus that can reduce energy consumption while allowing sounding elements to appropriately generate sound. A CPU supplies driving energy to an actuator to drivingly control the same based on pulse width modulation. A rotary pick is rotatively driven by the actuator to pluck reeds to generate sound. The CPU sets the duty of a driving pulse for driving the rotary pick during time points t3 and t4. Thus, higher driving energy is supplied to the actuator in timing in which the rotary pick plucks any of the reeds than in timing in which the rotary pick does not pluck any of the reeds.

Abstract: For musical instruments or sound reproduction, finer sound definition is preferable. In sound reproduction, electro-acoustic transducers fitted with round membranes or electrostatic system stripes are common. No system states that the sound created is correct for the human ear. The present method concerns a fractal shape responding to criteria of the human ear shape. A membrane which, like the ear via its shape, is a set of resonators with different frequencies. The membrane shape, known as a harmony amplifier, has independent tongues emitting from a given surface, like fingers of a hand coming out of the palm. A membrane can be put into digital form by tongues. The membrane is placed in a musical instrument. Another variant is a membrane mounted on a sound frequency generator constituting an electro-acoustic transducer. This is effective for all types of musical instruments and particularly for audio and audio-visual applications.

Abstract: Knockdown hand bell including two casings, a ram body and a hook member. The ram body serves to hit the casings and create a sound. The hook member serves to hook the ram body. The casings have multiple patterns and are replaceably mated with each other to form various types of hand bells to achieve a decorative effect.

Abstract: In a device for generating at least one sound by means of at least one sounding board (1) with vibrationally neutral surfaces, the sounding board (1) is joined to a holder (2) at least in the area of a vibrationally neutral surface.

Abstract: The sound bars of marimbas and the like are provided with one or more independently tuneable vibrattle tongues extending under the tuning arches of such bars for producing one or more different tonal effects.

Abstract: A vibration plate for a music box having an improved tonal range and quality, yet with a reduced manufacturing cost. The vibrating reeds of the vibration plate are made smaller in width towards the highest frequency one of the reeds. Each of the reeds has a base portion and an end portion extending through a sloped portion from the base portion, the end portion being smaller in width than the base portion. The end portions of the reeds are arranged at equal intervals.

Abstract: An electromechanical piano of the type incorporating asymmetrical tuning forks. To increase vastly the dwell of the forks in the high-pitched range of the piano, a fork-mounting construction is employed wherein only a single screw is associated with each fork. Elastomeric means are provided around each screw and also between opposed edge surfaces of adjacent forks, whereby to prevent rotation of each fork about the axis of its associated mounting screw.

Abstract: An acoustic sound generating device comprises a base frame, at least one vibrating rod member composed of a base end portion secured to said base frame, an intermediate portion having a small diameter and a free end portion to be picked, and a pawl segment having at least one associated picking projection for picking the free end. The pawl segment is operatively movable with the free end picked to thereby produce acoustic sounds.

Abstract: A musical instrument having an adjustable elongated member supported in an upright position on a collapsible base. A flat flexible sheet of metal, or other suitable materials capable of producing a musical tone when struck, is adjustably mounted on the upper end of the elongated member. An operator lever, pivotally mounted on the collapsable base, is connected to the flat flexible sheet by a cable. An actuator pedal on the operator lever enables it to be conveniently manipulated so as to selectively flex the flat flexible sheet when it is being struck by a percussive implement thereby producing variations in tone. A further variation in tone can be achieved by drawing a conventional violin bow across the edge of the flat flexible sheet as it is being flexed.

Abstract: A small musical comb is secured in a resonant housing and provides a plurality of musical bars of selective tone when vibrated. A separate manually operable rotary actuator carries one or more protrusions to successively engage the end of one bar and flex and then release it to vibrate the same.

Abstract: A box consisting of bottom, side and end walls forms a resonating chamber. An integral sounding panel has thickened ribs on the underside of its ends secured to the tops of the end walls with continuous side strips overlying the tops of the side walls of the chamber in spaced relation thereto. Between the side strips, the panel has three or more spaced longitudinal slots formed therethrough and extending between the ribs on the bottom of the panel. Transverse slots are formed between adjacent longitudinal slots at different distances from the ends of the panel forming vibratory fingers of different lengths. The undersides of the free ends of the fingers have thickened portions which are equal in thickness to the end ribs on the panel, and which extend from the free ends of all of the fingers to an equally spaced distance from the end ribs.
