The structure and composition of the speaker

　　The speaker is a transducer device that transforms the electrical signal into a sound signal. The performance of the speaker has a great impact on the sound quality. The speaker is a very weak device in the audio device, and it is an important component for the sound effect. The speakers are generally composed of dust caps, sound basins, sounds, vibration boards, basins, wiring columns, upper and lower magnetic poles, magnetic steel, etc.

　　Use the vibration of the sound basin (vibration film) to promote air vibration to achieve the sound of sound. Therefore, the material of the sound basin determines the personality of the speaker.

　　(1) Materials and characteristics commonly used in the medium -sized sound basin

　　1. Composite paper basin: Light weight, strong strength, mostly used for bass, and also used to restore vocal voices.

　　2. PP basin: synthetic plastic, waterproof, wide range of applications, but the performance is not the best, the price is low, which is a low -end product.

　　3. Metal basin: large strength, large weight, low sensitivity, and performing well for Des technology.

　　4. Silk linen: Mostly used for woven basins, the sound quality performance is the best, which is a high -end product.

　　(2) The materials and characteristics of the treble film (the sound basin is called the vibration membrane in the treble)

　　1. Organic membrane: Generally used for the treble of the coaxial speaker, it can bear the small power and is easily burned.

　　2. Metal membrane: The treble is clear, and it is even better than the silk membrane at high power.

　　3. Silk membrane: The sound quality is the best, especially when it is smaller.
