A communication device for an electronic musical instrument, comprising: an antenna for transmitting and receiving a radio signal of MIDI data and receiving a radio signal of audio data; a radio communication module for mutually converting the MIDI data and the radio signal of MIDI data and converting the radio signal of audio data into the audio data; a control device for mutually converting the MIDI data and a signal for a certain interface and converting the audio data into the signal for the certain interface; and a connector for transmitting and receiving the MIDI data as the signal for the certain interface to and from the electronic musical instrument and transmitting the audio data as the signal for the certain interface to the electronic musical instrument.

An example reverberation device configured for use with a musical instrument is disclosed. The example reverberation device comprises: (a) an input amplifier configured to receive an input signal from the musical instrument and output an amplified input signal based on the received input signal; (b) an input transducer connected to the input amplifier and configured to transmit the amplified input signal; (c) a reverberation plate comprising a bended surface, wherein the reverberation plate is connected to the input transducer, and wherein the reverberation plate is configured to output the input signal as an output signal at the bended surface; (d) an output transducer connected to the reverberation plate at the bended surface and configured to transmit the output signal; and (e) an output amplifier configured to receive the transmitted output signal from the output transducer and output an amplified output signal.

A musical instrument carrying case having a receptacle and a lid is disclosed herein. The carrying case has a hinge that allows the lid to rotate around behind the receptacle to create an instrument stand. The hinge has at least four plates and three axles, including a free axle that permits the hinge to collapse together, resulting in a shortened distance between the lid and receptacle when in an open position.

A simulated musical string instrument formed of plural shaped sheets of rigid material, such as cardboard. There is a top sheet forming a top surface of the simulated string instrument body, and a bottom sheet forming a bottom surface, and multiple sheets between. A simulated fingerboard is attached to the top surface. The top sheet and fingerboard gets stickers that show parts of the simulated string instrument body including openings and notes. There is also a simulated bow guide and a simulated bow.

An apparatus for emulating a variety of string instruments with a variety of configurations in order to measure the resulting, actual tension of a string on that instrument. The tension may be measured in real-time.

A guitar case comprises an upper body, a lower body, pivotally connected to the upper body, so that the upper body and lower body have a first closed configuration, for housing a guitar, the stowed guitar extending between the upper body and the lower body, the upper body and lower body have a second open configuration where the upper body is pivoted adjacent to the lower body. An amplifier and speakers are situated in the upper body, the speakers being directed outwards from the guitar case. Alternatively, the guitar case comprises a body an amplifier and two speakers, situated in the body, the two speakers positioned in a spaced relationship, the space separating them forming part of a cavity for accommodating the neck of a guitar the two speakers are joined a reinforcing yoke extending across the part of a cavity formed between the two speakers.

The invention concerns a method for reconfiguring a musical instrument. The method includes a step of applying a sticker on at least one technical surface of the musical instrument, characterized in that this application is made without glue and in that the sticker comprises an elastomer layer configured to come into contact with the technical surface and adhere to it in a reversible manner without application of glue. The invention further concerns a sticker and an associated manufacturing method.

The present invention relates to a saliva collector which comprises: a container which provides a space to accommodate at least one absorber; and a head wherein one end is detachably disposed on at least one part of a musical instrument and another end is detachably disposed so as to communicate with at least one part of a side of the container.
