Embodiment Construction

[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0023] One aspect of the present invention provides a dual-sound chamber current-limiting compression sound box structure, including: a speaker 1, a first sound chamber 2 and a second sound chamber 3, the first sound chamber 2 communicates with the The second sound chamber 3 is connected, the diameter of the channel 4 is less than half of the diameter of the horn 1, and the volume of the first sound chamber 2 is smaller than the volume of the second sound chamber 3, and The horn 1 is installed in the first sound chamber 2 . Preferably, the aperture area of ​​the channel 4 is one-third of the aperture area of ​​the vibrating plate of the horn 1 .

[0024] figure 1 It is the principle diagram when the horn compresses the air in the forward direction...

Abstract

The invention provides a double-sound-cavity current-limiting compression type sound box structure and a bullet type sound box. The double-sound-cavity current-limiting compression type sound box structure comprises a loudspeaker, a first sound cavity and a second sound cavity, the first sound cavity is communicated with the second sound cavity through a channel, the aperture of a vibration disc of the channel is smaller than more than one half of the aperture of a vibration disc of the loudspeaker, the size of the first sound cavity is smaller than that of the second sound cavity, and the loudspeaker is installed in the first sound cavity. The double-sound-cavity current-limiting compression type sound box structure has the effect of enhancing the low-frequency and ultra-low-frequency effects, the small-vibration-disc-caliber high-power loudspeaker can emit the ultra-strong bass and ultra-low-frequency sound effects, the structure refers to the bullet-shaped internal design, and the whole loudspeaker is novel and attractive in appearance.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a dual-cavity current-limiting compression sound box structure and a projectile body sound box. Background technique [0002] In the prior art, it is difficult for all low-frequency and ultra-low-frequency speakers to achieve strong and ideal low-frequency and ultra-low-frequency sound effects when using small-diameter speakers. In order to achieve strong and ideal low-frequency and ultra-low-frequency effects, it is necessary to increase the diameter of the speaker vibration plate to increase the load power of the speaker, so as to obtain the ideal sound effect. Contents of the invention [0003] The invention provides a dual-cavity current-limiting compression sound box structure and the sound box to solve the problem in the prior art that it is difficult to achieve strong and ideal low-frequency and ultra-low-frequency sound effects when using small-diameter speakers. ...
