An electronic musical instrument includes a condition determiner that determines whether an OFF condition for turning off a power supply is satisfied in an automatic power-OFF mode; a noise gate that is opened when a level of an input audio signal exceeds a threshold value and is closed when the level of the input audio signal continues being equal to or lower than the threshold value for a first predetermined period of time; and a controller that turns off the power supply on the condition that the condition determiner determines that the OFF condition is satisfied in the automatic power-OFF mode; and the controller does not turn off the power supply when the noise gate is in an open state, even in the case where the OFF condition is satisfied.

A wireless power supply system to for musical instrument comprises: a power supply device which is configured to wirelessly transmit microwaves, and a first power receiving device which is attached to a first musical instrument. The first power receiving device is configured to: receive the wirelessly transmitted microwave, and generate a first electric power from the received microwave, wherein the first electric power is supplied to at least one of a first electronic device installed in the first musical instrument and a first battery installed in the first musical instrument.

An acoustic guitar is provided that includes a neck and a body. The acoustic guitar also includes a user interface module including an audio effect module configured to implement one or more audio effects, and one or more effect controllers, with each effect controller being configured to set a level of a corresponding audio effect implemented by the audio effect module. The user interface module further includes at least one input blend controller and a voice controller configured to allow a user to select a patch from a plurality of available patches, with each patch of the plurality of available patches comprising a configuration of one or more audio effects set at various levels to arrive at a desired effect template.

A magnetic pedalboard system to supply power to effects pedals for use with a musical instrument is provided. The magnetic pedalboard system includes a base member, a pair of conductive strips coupled to the top surface of the base member and electrically coupled to a power supply, and at least one pedal coupled to the pair of conductive strips, the at least one pedal having a first portion of magnetic electrical contacts electrically coupled to a second portion of magnetic electrical contacts. The at least one pedal is designed to slide along any portion of the conductive strips with the first portion of magnetic electrical contacts directly coupled to the first conductive strip and the second portion of magnetic electrical contacts directly coupled to the second conductive strip, thereby permitting the power supply to transmit electricity through the conductive strips to the at least one pedal.

A circuit includes a signal processor configured to perform a signal processing, an amplifier configured to amplify a signal output from the signal processor, a first power supply path connected from a battery to the signal processor, a second power supply path connected from the battery to the amplifier, a capacitor connected to the second power supply path and that assists power supplied to the amplifier, and a power limiter connected to the second power supply path and that limits input power supplied from the battery.

An apparatus, system, and method for an electronic handheld musical instrument that generates electronic signals for processing by a processor-based module to generate musical sounds adapted to replicate non-electronic traditional hand percussion and other handheld instruments, is provided. A piezoelectric-based trigger is secured in an enclosed volume or enclosure formed in the electronic handheld musical instrument. When manipulated by a musician in a normal fashion, freely moving beads float or travel within the enclosure of the electronic handheld musical instrument and strike against a sensitive face of the piezoelectric transducer device to create a desired sound effect.

Methods and systems for assembling customizable solderless cables for direct current (DC) transmission of electricity to an electronic device. The systems and methods utilize shielded co-axial cable defining first and second opposed ends which may be cut to a desired length as selected by the user. Connectors, which may have a conventional 2.1 mm5.5 mm DC plug design, include a barrel portion defining a threaded axial passageway. In use, the threaded passageway of the plug is twisted upon a respective end of the cable such that the end of the cable becomes threadedly seated thereinto and in electrical contact with the plug to form two dedicated electrical connections. A respective other plug is mounted on the other respective end of the cable in the same manner to thus define the customizable cable. A single length of cable or a plurality of wire segments and plugs may be sold as a pre-packaged unit for use in making a plurality of customizable DC cables.

An instant-on nothing-to-download soundscaping device that provides natural, atonal sounds such as the rolling surf of the ocean, running streams, gurgling brooks, rain, thunder, wind, crowd sounds, et al is provided.

A power plate pedal board for musical instrument electronics is provided. An exemplary battery powered pedal board structure comprises: at least one battery; and control electronics, wherein the at least one battery and control electronics are housed within the battery powered pedal board structure, wherein the battery powered pedal board structure is configured to mount a plurality of musical effects pedals and to support a load applied to the plate assembly by one or more musician, and wherein the control electronics are configured to provide a plurality of outputs from one of the at least one battery, wherein the plurality of outputs comprise one or more of: (i) one or more outputs that are electrically isolated from each other and provide power to the plurality of musical effects pedals, and (ii) one or more outputs that are not electrically isolated from each other and provide power to one or more of the plurality of musical effects pedals.

An acoustic guitar is provided that includes a neck and a body. The acoustic guitar also includes a user interface module including an audio effect module configured to implement one or more audio effects, and one or more effect controllers, with each effect controller being configured to set a level of a corresponding audio effect implemented by the audio effect module. The user interface module further includes at least one input blend controller and a voice controller configured to allow a user to select a patch from a plurality of available patches, with each patch of the plurality of available patches comprising a configuration of one or more audio effects set at various levels to arrive at a desired effect template.
