Abstract
The utility model relates to a bass sound box with an embedded loudspeaker, characterized in that inside a box body there are provided two separator plates, the two separator plates separate the box body into a left cavity, a middle cavity, and a right cavity, the left and right cavities are equal in size and symmetrical in distribution, the two separator plates are respectively provided with a loudspeaker, the loudspeakers face to the middle cavity, the box walls in the left and right cavities, opposite to the loudspeakers are respectively provided with a small air pipe, and the box wall of the middle cavity is provided with a large air pipe. When audio signals are input, the two loudspeakers simultaneously emit sounds to resonate in the cavities, thereby increasing sound pressure, the sounds are emitted from the large air pipe, thereby simultaneously filtering various higher harmonics, greatly reducing harmonic distortion, greatly reducing the size of the box body under the condition of being equal in sound pressure, and increasing bass effect. The bass sound box with an embedded loudspeaker has the characteristics of being small in size, wide in frequency range, and small in distortion.
Description
Technical field
The utility model relates to a kind of audio amplifier, specifically is meant a kind of boombox woofer that has resonant cavity.
Background technology
The prior art patent No. 00219601.8 discloses a kind of structure of woofer; This woofer is provided with a dividing plate in the centre of audio amplifier; Make to form former and later two cavitys between casing and the dividing plate, the ante-chamber body forms a resonator system, and rear chamber is the cavity of a balance loud speaker tow sides pressure differential; And can adjust through the size of the balancing hole on the dividing plate; This structure can make loud speaker obtain the preferable stiffness and the less distortion factor, certain sound press lower box can do less, but this structure can't well be eliminated the audio distortions that high order harmonic component causes.
Summary of the invention
The purpose of the utility model is that it is wideer to propose a kind of frequency domain, can effectively eliminate the boombox woofer that high order harmonic component causes harmonic distortion to the problems referred to above.
The purpose of the utility model is achieved in that the boombox woofer of the utility model; It is characterized in that it is provided with two dividing plates in casing; Two dividing plates are divided into left cavity, middle chamber, right cavity to casing; Left side cavity and right cavity are two cavitys that equal and opposite in direction is symmetrically distributed, and two dividing plates are respectively equipped with loud speaker, and loud speaker is towards middle chamber; Be respectively equipped with little airduct on the tank wall of loud speaker dorsad in left side cavity and the right cavity, the tank wall of middle chamber is provided with big airduct.
The boombox woofer of the utility model, owing in the casing two dividing plates are set, two dividing plates are divided into left cavity, middle chamber, right cavity to casing; Left side cavity and right cavity are two cavitys that equal and opposite in direction is symmetrically distributed, and two dividing plates are respectively equipped with loud speaker, and loud speaker is towards middle chamber; When audio signal is imported, two loud speaker while sounding, sympathetic response in cavity; Promoted sound press, sent, can realize the complete equipilibrium of sound press difference simultaneously from big airduct; The various high order harmonic components of filtering reduce harmonic distortion greatly, and the little airduct of establishing in left cavity, the right cavity can effectively be widened the frequency range of low frequency.Equal sound press lower box can reduce greatly, and the effect of bass can get a promotion.Therefore, the utlity model has the characteristics that volume is little, frequency domain is wide, distortion is little.
Description of drawings
Fig. 1 is the connection sketch map of the boombox woofer of the utility model.
Embodiment
The utility model is described further through embodiment below in conjunction with accompanying drawing:
As shown in Figure 1, the boombox woofer of the utility model is characterized in that it is provided with dividing plate 4 and dividing plate 7 in casing; Dividing plate 4 and dividing plate 7 are divided into left cavity 2, middle chamber 5, right cavity 9 to casing; Left side cavity 2 is two cavitys that equal and opposite in direction is symmetrically distributed with right cavity 9, and dividing plate 4 is provided with loud speaker 3, and dividing plate 7 is provided with loud speaker 8; Loud speaker 3 and loud speaker 8 are towards middle chamber 5; A left side cavity 2 in dorsad the tank wall of loud speaker 3 be provided with little airduct 1, in the right cavity 9 dorsad the tank wall of loud speaker 8 be provided with little airduct 10, the tank wall of middle chamber 5 is provided with big airduct 6.
