Abstract

The embodiment of the present application discloses a method and device for determining the audio frequency of a piano key, which is applied to a key detection platform. The key detection platform includes an antenna array, and the antenna array includes a plurality of antenna units, and each antenna unit sends signals and signals based on inductive coupling. receive signal. The method includes: transmitting a first detection signal based on an antenna unit in the antenna array, the first detection signal is used to identify a key pressed in the keyboard, the key includes a first detection signal transmitted by the antenna unit for receiving the antenna array The electronic tag that signals and feeds back the response signal; receives the response signal fed back by the electronic tag of each key in the multiple keys of the piano based on the antenna array, and determines the key tone corresponding to each key according to the response signal fed back by the electronic tag of each key. By adopting the embodiment of the present application, the cost of determining the key-press sound of the keys is low, the degree of realization is high, and the scope of application is wide.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for determining the audio frequency of a key. Background technique [0002] In a traditional electronic keyboard or piano, each key is a small switch in the circuit. When a key is pressed, its corresponding small switch is closed, so that the virtual key pressed can be determined and the corresponding virtual key is output. Touch-tone. However, this kind of electronic organ or piano is expensive, and cannot recognize the sheet music, so the applicability is not high. Contents of the invention [0003] Embodiments of the present application provide a method and device for determining the audio frequency of a piano key. The cost of determining the key tone can be reduced, the implementation degree is high, and the application range is wide. [0004] In the first aspect, an embodiment of the present application provides a method for determining t...
