[0002] Speakers, commonly known as "horns", are a very commonly used electroacoustic transducer device, which is a transducer device that converts electrical signals into acoustic signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest device in the audio equipment, but it is the most important component for the sound effect. There are many types of speakers, and the prices vary greatly. Audio power vibrates the cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects and resonates (resonates) with the surrounding air to produce sound. Micro speakers refer to smaller speakers, which are usually used in smart home devices, such as smart speakers, smart doorbells, etc. It has the characteristics of being small and light, low power consumption, and high sound quality, and can provide clear and high-quality sound output for smart home devices.

[0003] A spring wave is needed inside the micro speaker. 主要作 The purpose is to maintain the correct position of the voice coil in the electromagnetic system in the magnetic gap, to ensure that when the voice coil is subjected to force, the electromagnetic system reciprocates axially, and the mechanical wave system jointly determines the efficiency of the speaker and prevents dust from entering the magnetic gap.
