Description

A speaker

Technical Field

The utility model relates to the field of acoustic devices, in particular to a loudspeaker.

Background Art

Loudspeakers, commonly known as speakers, are widely used in various types of electro-acoustic equipment, including various multimedia audio systems, computers, DVDs, televisions, telephones, mobile phones, cars, and various industrial and civil instruments and equipment sound-generating parts. However, the sound that the human ear can distinguish always has full-band sound waves of treble, midrange and bass frequencies. If only a woofer is used as a sound-generating device, the high-frequency range of the sound will be insufficient; similarly, if only a tweeter is used as a sound-generating device, the low-frequency range of the sound will be distorted. The usual way to solve this problem is to install the tweeter and the woofer in a sound-generating device (such as a speaker) at the same time, separate the audio current through a frequency divider, connect the high-frequency current to the tweeter voice coil, and connect the low-frequency current to the woofer voice coil. In this way, although the sound quality has been greatly improved, since the tweeter and the woofer are located in different geometric positions of the sound-generating device, the sound restored by the sound-generating device is still distorted to a certain extent from the actual natural sound, and the sound quality is poor.

Therefore, how to improve the sound quality of speakers has become a difficult problem that needs to be solved urgently in this field.
