A communication device for an electronic musical instrument includes a battery; an input terminal that is connected to a MIDI output terminal of the electronic musical instrument; an output terminal that is connected to a MIDI input terminal of the electronic musical instrument; a control unit that transmits and receives various kinds of electronic information between the electronic musical instrument and the other electronic instrument via the input terminal and the output terminal; and a switching unit that switches between taking in electric power to be supplied to the control unit through a MIDI signal line from the electronic musical instrument via the input terminal and taking in the electric power from the battery in accordance with a communication state of the control unit.

A stringed instrument tuner that senses the vibration of all the strings of the instrument independently and simultaneously via ultraviolet reflective light sensors that are immune to interference from ambient alternating-current lighting. The pitches of the strings are then measured continuously in real-time and transmitted wirelessly to a receiver that simultaneously graphically displays how far out-of-tune all of the strings are so that the musician can instantly see which strings need tuning and tune them quickly. The receiver may be a smartphone, smartwatch, smart glasses, computer, self-tuning system, or a dedicated wearable receiver-display unit.

The present invention discloses an integrated karaoke device, including a microphone and a sound box. The sound box includes a sound chamber containing a loudspeaker. The integrated karaoke device further includes a connecting part made of flexible material that is fixedly connected between a bottom of the microphone and a top of the sound chamber. The use of a flexible material connecting part rather than a solid structural part reduces the transmission to the microphone of sound vibration generated by the sound box. The beneficial effect of implementing the present invention is that a flexible material connecting part is fixedly connected between the bottom of the microphone and the top of the sound chamber, and meanwhile, a gap is kept between the bottom of a printed circuit board (PCB) and the top of the sound chamber; and because the flexible material connecting part can effectively reduce sound vibration, the transmission of vibration to the microphone from the sound box can be effectively eliminated, thereby preventing squealing, and enabling integration of the microphone and the sound box for use in karaoke.

A specialized audio/instrument cable with built-in digital signal processing capabilities that adds user-defined audio effects (such as reverb, delay, chorus and/or distortion) from within the cable itself to affect the sound generated from an instrument or microphone such that the cable is the only connection needed between the instrument or microphone and an output device (such as an amplifier, PA, powered speaker, music mixer, or a recording device). The audio effects used by the cable can be changed via (i) an app from a smartphone, tablet, computer or other electronic device; (ii) a wireless controller that attaches to the instrument; (iii) a pedal, and/or (iv) any other type of wireless controller that has the ability to communicate with a smartphone/tablet/computer or other electronic device.

A wireless headset configured to process music interface protocol (e.g., the Musical Instrument Digital Interface (MIDI) protocol) received wirelessly (e.g., via a Bluetooth™ connection or an Internet connection) by a source device is described herein. The wireless headset includes a first and second headset speaker and a wireless transceiver unit to receive a stream of data over a wireless connection. The wireless transceiver unit includes a sound processing logic unit that converts the stream of data to a stream of data associated with a music interface protocol outputs audio corresponding to the converted stream of data to the first and second headset speakers.

An input device for operating a musical instrument having musical behavior of string instruments, which comprises a key plate unit containing a set of input keys to be pressed by a player, in order to generate a first set of electric input signals, which emulate a combination of pressed keys of a musical instrument or a combination of pressed strings; a stick unit with variable tension of displacement including a stick to be moved by the player between predetermined discrete positions, which emulate a combination of strummed strings of a musical instrument.

An instructional method of an electronic keyboard includes the following steps: obtaining a playing script, wherein the playing script is generated by a recording electronic keyboard; the recording electronic keyboard generates the playing script according to a pressed second key and the time of pressing the second key, and the playing script is used for indicating a corresponding relationship between a to-be-pressed key and the time of pressing the to-be-pressed key; controlling an indicator light on the first key of the instructional electronic keyboard to be turned on/off according to the playing script. In this implementation mode, a user can be prompted for the key by an indicator light on the electronic keyboard, which facilitates the user to learn the electronic keyboard.
