Description

Music system using Bluetooth communication

This creation is about a music system. More specifically, the present writing is directed to a music system that uses Bluetooth communication.

A conventional music device (for example, a keyboard or other electronic musical instrument) itself has a rear-stage amplifying circuit and a speaker, which can be used alone to play a song, but lacks instant two-way wireless communication with other music devices or smart terminal devices. The function, and therefore cannot cooperate with other devices to form a two-way interactive music system.

In addition, accompaniment music and teaching demonstration songs are usually stored in the music equipment for the purpose of performance and use. In order to select or switch functions, additional buttons and display elements need to be set on the music device, which leads to an increase in cost and a limitation on the size of the device. Moreover, the aforementioned accompaniment music and teaching demonstrations also require the use of additional fixed storage devices, but the user cannot replace the music stored therein.

Later, there was also a product called the Musical Instrument Digital Interface (MIDI), which converted the player's performance into a MIDI message and wired it to another professional and expensive MIDI synthesizer via the MIDI protocol. However, the MIDI keyboard itself cannot speak, and it cannot overcome the shortcomings of the above-mentioned conventional music equipment. With the popularization of portable terminal devices such as mobile phones and laptops, there has recently been a wireless Bluetooth keyboard system that can be connected to smart terminal devices, but it also has the disadvantages of the above-mentioned conventional music devices, and is easy to carry.
