[0002] Audio refers specifically to an audio system that produces sound through a combination of electrical equipment. The development history of audio technology can be divided into four stages: electron tubes, transistors, integrated circuits, and field-effect transistors. With the progress of society, people yearn for a more colorful life. As a form of entertainment that has been passed down for thousands of years, singing and dancing have penetrated into the lives of people of all ethnic groups. However, with the development and progress of science and technology, people have more and more requirements for the performance forms and venues of singing and dancing. The audio system is constantly improving and perfecting with people's needs. It can be as large as meeting the needs of live sound reinforcement for concerts with tens of thousands of people, or as small as meeting the needs of playing musical instruments and singing karaoke at home.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5 A magnetic combined audio system includes a plurality of magnetic combined audio units 1, a speaker 2 is provided in front of the audio unit 1, a diaphragm 16 is provided on the back, magnets 3 are respectively installed on the top and bottom of the audio unit 1, a connecting contact 4 is provided on the top surface of the audio unit 1, and an elastic contact pin 5 corresponding to the connecting contact is provided on the bottom surface of the audio unit 1. A plurality of audio units 1 are stacked, and the connecting contact 4 of one of the audio units 1 in two adjacent layers is in contact with the elastic contact pin 5 of another audio unit 1 to form a circuit and signal connection between the audio units 1. Specifically, one of several audio units 1 can be used as the main audio input unit. When multiple audio units 1 are stacked, the connection contacts 4 and elastic contact pins 5 of two adjacent layers of audio units 1 will be in contact and connected, thereby forming a circuit and signal connection. Multiple audio units 1 can be conveniently combined and sound synchronously to achieve a multi-channel effect. At the same time, since multiple audio units sound synchronously and multiple sound fields are synchronously superimposed, the loudness and sound pressure of the audio are improved, thereby achieving a high-power, high-fidelity effect. When the power of a certain audio unit 1 is low, it can also be charged through other audio units 1. When an audio unit 1 is damaged, it only needs to be removed or replaced to continue to be used, which is convenient for maintenance without affecting the normal use of the audio. Among them, the main audio input can adopt input methods such as Bluetooth and audio cable. In addition, magnets 3 are installed on the top and bottom of each audio unit 1, so that the audio units 1 can be easily combined together.

[0022] Furthermore, it also includes a circuit board 6 connected to the speaker 2, the connection contact 4, and the elastic contact pin 5, and a control panel 7 connected to the circuit board 6. The speaker 2 is arranged on the front or rear end surface of the audio unit 1, and the control panel 7 is arranged on the side of the audio unit 1. Specifically, the circuit board 6 is respectively provided with a power supply terminal J1 and a signal terminal J2 connected to the connection contact 4 and the elastic contact pin 5, and the power supply and signal systems of the two audio units 1 are integrated into a whole through the connection contact 4 and the elastic contact pin 5 between the two audio units 1, so that the two audio units can sound synchronously, and can also be charged when the power of one audio unit 1 is low. According to the above principle, more than two audio units 1 can be superimposed on this basis to form a multi-audio system.

[0023] Furthermore, in order to improve the durability and safety of the audio system, mesh covers 8 are provided on the front and back of the audio system unit 1 to prevent dust and foreign matter from entering the interior of the audio system.

[0024] Furthermore, the top surface of the audio unit 1 is provided with a protrusion 9, and the bottom surface is provided with a groove 10 that matches the shape of the protrusion 9. This design can make the audio units 1 more stably combined together to prevent them from loosening or falling off during use. The protrusion 9 is also provided with a long and a short alignment strip 11, and the groove 10 is provided with an alignment groove 12 corresponding to the alignment strip 11, which further improves the connection stability and accuracy between the audio units 1.

[0025] Furthermore, a battery 13 connected to the circuit board 6 is provided in the audio unit 1, and a charging port 14 is provided on the control panel 7, so that the user can charge the audio. In addition, a Bluetooth module 15 is integrated on the circuit board 6, so that the audio can be connected to mobile phones, tablets and other devices wirelessly to achieve more convenient music playback and control. In addition, when multiple audio units 1 are connected, when a smart device is connected to the Bluetooth module 15 of one of the audio units 1, the audio unit 1 can output a signal to the remaining audio units 1 to control the remaining audio units 1 to temporarily turn off the Bluetooth modules 15, thereby preventing interference with each other. The Bluetooth module 15 is turned on again after the Bluetooth connection is disconnected or the audio unit 1 is removed from the system.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
