Double-vibrating-diaphragm loudspeaker box

Abstract

Disclosed is a double-vibrating-diaphragm loudspeaker box. The side view of an inner shell of the loudspeaker box is in a U shape. A through groove is formed in the middle of the U shape. An upper vibrating diaphragm is fixedly installed above the through groove. A lower vibrating diaphragm is fixedly installed below the through groove. A loudspeaker is fixedly installed inside the inner shell. A sound output hole is formed in the position, corresponding to the loudspeaker, of the inner shell. The whole inner shell is of a sealing structure. Reverse-direction airflow generated when the loudspeaker makes a sound can drive the two vibrating diaphragms to vibrate at the same time. When the double-vibrating-diaphragm loudspeaker box works, the sound made by the loudspeaker is added to the two vibrating diaphragms through a sealed loudspeaker box cavity, so that the two vibrating diaphragms move outwards or inwards along with the airflow of the loudspeaker at the same time, and bass heard by the ears of a person is increased by one time. Meanwhile, as for a loudspeaker box body, the moving directions of the two vibrating diaphragms are just opposite, so that the balancing aim is achieved, and the aim that compared with a loudspeaker with the general design, the double-vibrating-diaphragm loudspeaker box has the better sound restoration effect, namely the high fidelity effect is achieved.

Description

technical field [0001] The invention discloses a sound box, in particular to a sound box with double vibrating diaphragms. Background technique [0002] Speakers are audio output devices commonly used by people and are widely used in people's lives. All speakers in the prior art can be roughly divided into: fully enclosed structure, inverted structure and single diaphragm structure. Among them, the fully enclosed structure And the inverted structure has very strict requirements on the speaker's own unit and the internal structure of the speaker. It is difficult for a small-sized speaker to achieve a good acoustic performance. Therefore, the small-sized speakers on the market basically use a single-diaphragm structure to enhance the bass. effect, but the disadvantage of this method is that when the diaphragm is working, because it adopts a single-directional force structure, the entire speaker will move in the direction of the strength of the diaphragm, which will It...

Therefore, the small-sized speakers on the market basically use a single-diaphragm structure to enhance the bass. effect, but the disadvantage of this method is that when the diaphragm is working, because it adopts a single-directional force structure, the entire speaker will move in the direction of the strength of the diaphragm, which will Produces very large sound coloration, resulting in greatly reduced sound reproduction (ie, speaker fidelity)
