The disclosure relates to a mesh-head electronic drum, including a drum base, a drum head, a data acquisition module and a data processing module, wherein the data acquisition module includes a trigger unit and a conduction medium, the conduction medium is a magnetic unit, the magnetic unit is arranged on the drum head, and the trigger unit includes a Hall sensor coupled with the magnetic unit in a non-contact way. The disclosure is advantageous in that the trigger unit and the conduction medium have no direct contact with each other and thus no bad contact is caused, but an accurate audio signal can still be generated.

In a method and apparatus for magnetic resonance imaging with a music-based gradient curve, a magnetic resonance sequence and a piece of music are provided to a controller of a magnetic resonance apparatus. The piece of music is modified in the controller by taking into account at least one acoustic resonance parameter that characterizes at least one acoustic resonance frequency of the magnetic resonance apparatus, so a modified piece of music is generated. A gradient curve of the magnetic resonance sequence is adjusted using the modified piece of music, so an adjusted magnetic resonance sequence is generated. Magnetic resonance image data of the examination object is acquired by operation of the apparatus with of the adjusted magnetic resonance sequence.

A hair razor with interactive features including RPM control protocol that includes: an under side; an interactive display placed on the under side, where the interactive display provides access to display applications stored in memory; a top side; a digital display on the top side, where the digital display provides operational information related to the hair razor; a motor; a motherboard, where the motherboard is adapted to provide RPM control for the motor, wherein said RPM control is accomplished by syncing RPM speeds with musical notes; a USB connector on one side of the hair razor; a touch control button on the top side of the hair razor; and a power cord, the power cord supplies power to the hair razor. The interactive display is adapted to maneuver through a plurality of screen selections. The operational information shown on the digital display includes pitch tone associated with the RPM speed of the motor.

An electronic device is provided. The electronic device includes a touch screen display, at least one of a speaker and a sound interface, a processor configured to electrically connect to the touch screen display, the speaker, and the sound interface, and a memory configured to electrically connect to the processor. The memory stores instructions for, when executed, causing the processor to display at least one item comprising a musical instrument shape on the touch screen display, receive a touch input through the touch screen display, load sound data corresponding to the at least one item based on the touch input, process the sound data based at least in part on information associated with the touch input, and output the processed sound data through the speaker or the sound interface.

Provided is an electronic musical instrument system. A PC is configured to perform an operation of emulating an analog synthesizer by a first software synthesizer. The PC installs a second software synthesizer to a hardware synthesizer on condition that the hardware synthesizer is confirmed to be the device corresponding to the second software synthesizer. The hardware synthesizer performs the operation of emulating the analog synthesizer by the second software synthesizer. The first software synthesizer and the second software synthesizer related to the operation of emulating the analog synthesizer have the same function respectively, and are capable of generating the same tone respectively, the effect of reproducing the same function and tone as the synthesizer that is to be emulated can be achieved respectively in two different devices, i.e. the PC and the hardware synthesizer.

A symphony playing method using an electronic device includes calculating a distance value between a first GPS device of a first detecting device and a distal terminal of a baton. An angle between a first straight line and a second straight line is calculated. A capturing device is controlled to capture images of hand gestures of a user. Once a music instrument is determined to be currently pointed to by the distal terminal of the baton, according to the first distance value and the calculated angle, and a beat is determined according to the captured images, notes on the symphony is played using a tone of the determined music instrument according to the determined beat.
