Technical Field
The invention belongs to the field of electronic musical instrument design, and particularly relates to electronic musical instrument equipment capable of being locked and unlocked in a rotating mode.
Background
An electronic drum musical instrument includes a drum sound source device (tone color generating apparatus including a sound source device and a control panel), one or more drum trigger devices including a plurality of drum triggers for simulating various real drum tones, and a sound amplifying device, wherein the drum trigger device connected to the drum sound source device generally includes: hihat hi-hat, kick bottom drum, snare military drum, tom1 drum, tom2 drum 2, tom3 drum 3, ride dingHill, etc. Different tone colors are emitted when different drum triggers or trigger positions thereof are knocked. Different drum triggers are connected with the drum sound source equipment through respective connecting wires.
For example, striking a snare drum triggers the tone of the snare drum, striking the RIDE to a cymbal triggers the tone of the cymbal. Through striking different drum trigger, the signal of telecommunication is transmitted to drum sound source equipment through corresponding connecting wire, and drum sound source equipment stores the tone color sample of each percussion music, and it produces corresponding tone color according to the striking signal from different drum trigger to sound through the power amplifier. Specifically: when a drummer hits the drumhead (snare drum), it is caused to vibrate, and the vibrations are received (snare drum sensor). The sensor converts the vibrations into an electrical signal. The electrical signal is output at a drum port (snare drum port). The signal is transmitted to the sound source chip in the sound source device through the drum connecting wire (military drum cable) to produce sound, wherein the sound source chip in the sound source device stores the analog sampling tone sampled from the acoustic drum kit. When a drummer strikes the drumhead (cymbals), it is caused to vibrate. The vibrations are received (by a cymbal sensor), which converts the vibrations into an electrical signal. The electrical signal is output at the drum port (the cymbal port). The signal is transmitted to the sound source chip in the sound source device through the drum connecting wire (the cymbal cable).
