[0002] A speaker generally refers to a device in an audio system that converts audio signals into sound. As the terminal of the entire audio system, its function is to convert audio electrical energy into corresponding sound energy and radiate the sound signal into space. The sound-emitting element in the speaker is a speaker, also called a loudspeaker. The speaker is fixed to the speaker body, and the speaker body has a sound outlet. The speaker emits sound toward the sound outlet of the speaker body. Speakers have gradually become one of the indispensable electronic products in people's lives. With the development of society and the improvement of living standards, people have higher and higher requirements for audio-visual electronic products. The types of speakers are becoming more and more diverse, the functions are becoming more and more complete, and the sound effects are gradually improving. Small and multifunctional speakers have very good portability and practicality, and are gradually valued and accepted by consumers.

[0003] Small-sized multi-functional speakers are usually equipped with a smaller display screen, which can display interfaces corresponding to multiple functions, and requires control keys for operation selection and switching; the joystick control button assembly can realize multi-directional selection and confirmation control functions, and has the characteristics of small size, rich functions, and easy operation. Therefore, it is very suitable for installation on electronic products such as small-sized multi-functional speakers.

[0004] A multifunctional smart speaker disclosed in the related technology includes a box body, a base, wheels and a remote control handle, the wheels are fixedly installed at the bottom of the base, brake pads are fixedly installed on the wheels, the box body is fixedly installed on the top of the base, a display screen is fixedly installed on the outside of the box body, a voice recognition device is fixedly installed on the bottom of the display screen, a speaker is fixedly installed on the bottom of the voice recognition device, a monitoring device is fixedly installed on the top of the box body, a number of glare lights are fixedly installed on the side walls on both sides of the inside of the box body, a number of lamp beads are fixedly installed inside the glare lights, power wires are fixedly connected between the several glare lights, a number of control buttons are fixedly installed on the outside of the remote control handle, a control joystick is fixedly installed at the bottom of the control buttons, and a vibration sensor is fixedly installed on the top of the remote control handle.

[0005] The joystick control button assembly is installed on the corresponding potentiometer on the circuit board. For such lightweight products, whether the joystick control button assembly is set on the speaker body or on an independent remote control, the fixed connection of the corresponding potentiometer on the circuit board is relatively fragile. During frequent use, the potentiometer and joystick control button assembly are very easy to fall off or be damaged, thus affecting their service life. Utility Model Content
