Embodiment Construction

[0023] see figure 1 , an embodiment of the present invention provides an electronic musical instrument, including a main body 100, a processor (not shown) and at least two sensor groups, each sensor group is respectively arranged on the main body 100, and any sensor group includes at least two non- The contact sensors, and the non-contact sensors in each sensor group are respectively connected to the processor; wherein, each non-contact sensor corresponds to an identity mark.

[0024] When the processor receives the work order, it starts timing, and uses any sensor group in each sensor group as the current sensor group to trigger the current sensor group to emit the first signal. When the first return signal corresponding to the transmitted first signal is received within the preset duration range, the processor obtains the first striking distance according to the receiving time of the first return signal and the transmitting time of the first signal, and upon receiving the fi...

Abstract

The application relates to an electronic musical instrument. A current sensor group among all sensor groups is triggered to work and a first signal is emitted; when a corresponding first return signalis received, a first beat distance is obtained according to the receiving time of the first return signal and emission time of the first signal; a second beat distance is obtained based on receivingtime of a second return signal and emission time of a second signal; on the basis of the first beat distance, the second beat distance, and a preset threshold value, a beat speed is obtained and thusthe sound that has a volume corresponding to the beat speed and has the tone corresponding to an identity label of a non-contact sensor receiving the first return signal is made. When the timing length reaches a preset period of time, a next sensor group among all sensor groups is used as a current sensor group and execution the work of triggering the current sensor group is done again, so that all sensor groups are triggered in turn. Therefore, a problem that the interference is easy to cause when all sensors work simultaneously is solved; and the sensing accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an electronic musical instrument. Background technique [0002] In recent years, the electronic technology of musical instruments has gradually become the key content in the field of electronic research, resulting in a variety of electronic musical instruments, and electronic drums are one of the common electronic musical instruments. The electronic drum is a musical instrument in which the musician triggers an electronic signal by hitting the drum surface, and then uses electronic synthesis technology or sampling technology to process the new electronic signal, and then emits sound through the electro-acoustic equipment. Common electronic musical instruments with rubber electronic board and mesh simulation (also known as mesh drum head) electronic musical instruments, electronic musical instruments with rubber electronic board use rubber material as the panel, and e...
