Abstract
A sound box structure with the extra bass effect is characterized in that a partition board is arranged in a box body and divides the box body into a left cavity, a right cavity and a back cavity, wherein an opening is arranged on the left cavity, at least one woofer is arranged on the right cavity, and the right cavity, the back cavity and the left cavity are communicated. In the sound box structure with the extra bass effect provided by the utility model, the internal structure of the box body is designed into a structure similar to a feed-through pipeline, the voice radiated from the back part of the woofer can enhance the voice radiated at a low frequency of the entire sound box after being conveyed through the pipeline, and meanwhile the lower limit of the low frequency is improved, thereby achieving the purpose of expanding the frequency range of the sound box, lifting the lower limit of the low frequency, and improving the quality of sounds. Simultaneously, the woofer, an intermediate frequency loudspeaker and a tweeter are integrated into a whole as a strip-shaped sound box.
Description
Technical field
The utility model relates to a kind of audio amplifier, specifically is meant a kind of loudspeaker box structure that has the big bottom effect of 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 and form former and later two cavitys between casing and the dividing plate, the ante-chamber body forms a resonator system, rear chamber is the cavity of a balance loud speaker tow sides pressure differential, and can adjust by 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.
Summary of the invention
The utility model is to propose another version, and the structure that changes casing reaches the frequency range of widening audio amplifier, the purpose that promotes low-frequency minimum, raising tonequality.
The purpose of this utility model is achieved in that the loudspeaker box structure of big bottom effect of the present utility model, it is characterized in that it is provided with dividing plate in casing, dividing plate is divided into left cavity, right cavity and rear chamber to casing, on the cavity of a left side opening is arranged, have a woofer at least on the right cavity, right cavity, rear chamber and left cavity connect; Also mid frequency ludspeaker and tweeter can be arranged respectively on right cavity and the left cavity.
The loudspeaker box structure of big bottom effect of the present utility model, box inner structure is made the design of similar perforation pipeline, the sound of woofer back radiation is through the transmission of piping, standing wave tunning effect by pipeline, make the frequency of sound wave of pipeline tapping radiation more be lower than the frequency of loud speaker head-on radiation sound wave, the phase place of pipeline tapping radiative acoustic wave just in time equates with the phase place of loud speaker head-on radiation sound wave simultaneously, the sound of pipeline tapping radiation and the stack of loud speaker head-on radiation acoustic phase, the sound of so whole audio amplifier low frequency radiation has just obtained enhancing, low-frequency minimum also gets a promotion simultaneously, reaches the frequency range of expanding audio amplifier, promote low-frequency minimum, improve the purpose of tonequality.
Simultaneously, also woofer, mid frequency ludspeaker and tweeter can be become one, be integrated into the audio amplifier of a formula.
Description of drawings
Fig. 1 is the connection diagram of the loudspeaker box structure of big bottom effect of the present utility model.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
As shown in Figure 1, the loudspeaker box structure of big bottom effect of the present utility model, it is characterized in that it is provided with dividing plate 5 in casing, dividing plate 5 is divided into left cavity 4, right cavity 7 and rear chamber 9 to casing, on the cavity 4 of a left side opening 6 is arranged, on the right cavity 7 woofer 8 is arranged, right cavity 7, rear chamber 9 and left cavity 4 connect, also have mid frequency ludspeaker 10 and tweeter 11 on the right cavity 7, also have mid frequency ludspeaker 3 and tweeter 2 on the left cavity 4.
