1.6- 10 inch rubber edge speaker is used as a woofer.
The 2.3-inch speaker is used as the alto speaker (it can be omitted, and the bass speaker can take care of the alto).
3. 1 inch dome speakers are used for treble (two speakers are allowed if conditions permit).
4. Select the appropriate frequency divider.
5. Phase reversal hole
6.2cm hard high-density board (too thin will make bass vibration noise, the stronger the better).
7. Terminals (junction box and terminal bracket).
8. Internal wiring, which is all the complete information.
Sound box is the terminal of the whole sound system, and its function is to convert audio electric energy into corresponding sound energy and radiate it into space. It is an extremely important part of the sound system, because it is responsible for the key task of converting electrical signals into acoustic signals for people to listen to directly. It has to deal directly with people's hearing, which is very sensitive and has a strong ability to distinguish the timbre of complex sounds. Because the human ear's subjective feeling of sound is the most important criterion to evaluate the sound quality of an audio system, it can be considered that the performance of speakers plays a key role in the sound quality of an audio system.
