The present invention provides a chordophone including a body configured to have a top plate, a bottom plate, and a side plate connected to the top plate and the bottom plate, which comprises: a cut-out plate formed by cutting the bottom plate, and configured to have a grille formed on a portion penetrated of the cut-out plate; a bracket formed in a shape corresponding to the cut-out plate and configured to have a base plate coupled to an inner side of the cut-out plate; and a speaker unit configured to have a speaker installed in the bracket, a control unit for controlling an output of the speaker, and a communication module for allowing a sound source output from the speaker to be received from an external user terminal, in which the grille is formed in a size and shape corresponding to a diameter of a side on which a sound of the speaker is output, and a through-hole is formed penetrated on the base plate at a corresponding position to the grille and with a corresponding shape to a shape of the sound output side of the speaker.

A multifunctional guitar includes a guitar body, a handle detachably connected to the guitar body, a Bluetooth speaker, and a shock absorbing mechanism that connects the Bluetooth speaker to the guitar body.

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 small (smartphone-sized or tablet-sized), foot-enabled, flat, tiltable, rotatable, dynamic touch screen pedal and controller that uses a tilt mechanism to toggle between and select different audio (or other) functions and effects that are displayed on the attached display. The tilt of the device as well as optional tapping sequences activate different functions in predetermined function locations. Specific audio effects, audio effect presets, loops, songs, and controller functions can each be assigned to different touch screen locations, pedal buttons, and/or tilt directions.

An audio signal output system including a first audio signal path, a second audio signal path and control electronics that provide a mixed sound from sound sources to the first and second audio signal paths, and control the mixed sound in accordance with a position at which a sound image associated with at least one of the sound sources is localized relative to an orientation of a user's head. The control electronics provide one or more signals corresponding to the mixed sound to the first and second audio signal paths based on one or more transfer functions associated with one or more values corresponding to at least one of a distance from the user to the at least one sound source, an angle of the user with respect to the at least one sound source, and a size of a space in which the user is located.

A communication system including a terminal, an electronic device, and a server is provided. The terminal includes a login part logging in to the server, an identifier reception part receiving a device identifier corresponding to a user who has logged in, and a terminal instruction transmission part transmitting to the server the device identifier received by the identifier reception part and an instruction for the electronic device. The server includes an identifier storage part storing a user identifier in association with the device identifier of the electronic device corresponding to the user, an identifier transmission part acquiring device identifier corresponding to the user identifier and transmitting the device identifier to the terminal, a first server instruction reception part receiving the device identifier and the instruction for the electronic device, and a server instruction transmission part transmitting the received instruction to the electronic device corresponding to the received device identifier.

A vocal music production apparatus for converting vocalized music to produced instrumentals includes a housing front side, a housing back side, a housing left side, a housing right side, a housing top side, and a housing bottom side. A touch screen is coupled to the housing within the housing front side. A microprocessor is coupled within the housing and is in operational communication with the touch screen. The microprocessor includes a digital synthesizer to convert vocal audio inputs to digital music. A microphone, a speaker, a headphone jack, and a battery are coupled to the housing and are in operational communication with the microprocessor. A port is coupled to the housing and is in operational communication with the microprocessor and the battery. A plurality of control buttons is coupled to the housing and is in operational communication with the microprocessor.

This information processing device comprises: a control unit which receives an input of information indicating one or more timings in a playback time of a piece of music, and generates a file including information pertaining to a timbre control performed from each of the one or more timings; and a transmission unit which transmits an audio signal of the piece of music and the information pertaining to the timbre control in the file to a device which outputs a synthesized sound of the playback sound of the piece of music and the playing sound of a musical instrument.

A system including: an electronic memory device and a processor. The processor is configured to: control a communication device to receive first input information indicating a first instruction, the first instruction corresponding to control of sound associated with at least one first sound source; control a transmitter of the communication device to transmit first information to an audio output device, the first information corresponding to the first input information indicating the first instruction; control the communication device to receive second input information indicating a second instruction corresponding to control of sound associated with the at least one second sound source; and control the transmitter to transmit second information to the audio output device, the second information including or corresponding to an audio signal associated with the at least one second sound source and processed according to the second input information indicating the second instruction.

Provided are an electric musical instrument system and a control method thereof. The electric musical instrument system includes a musical sound transmitting means and a musical sound receiving means having a first mode and a second mode that consumes less electric power than the first mode. The musical sound transmitting means has a detecting means for detecting rocking of a musical instrument and a transmitting means that transmits an audio signal emitted from the musical instrument to the musical sound receiving means in the first mode and transmits, when detecting rocking of the musical instruments, detected information to the musical sound receiving means in the second mode. The musical sound receiving means has a controlling means that processes the audio signal received in the first mode and cancels the second mode and changes the mode to the first mode when the detected information is received in the second mode.
