Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-4, single loud speaker super low voice box structural representation of the utility model preferred embodiment, comprise a woofer 4 and a casing 1, the casing 1 of single loud speaker super low voice box of the present utility model can adopt wood materials or plastic material to make, described casing 1 inside is provided with cavity, side and the front of described casing 1 are provided with outlet sound mouth 2, preferably, described outlet sound mouth 2 is circular or square, and the outlet sound mouth 2 in the side of casing 1 and front is provided with phonocatheter (not indicating in figure) to described cavity, the sound wave of box house is better blazed abroad by phonocatheter.The framework 3 in W type is provided with in described cavity, described framework is positioned at the center of casing 1, described framework 3 is only connected with inwall below with the front inside wall of described casing 1, described woofer 4 is installed on the center of described framework 3 and faces up, preferably, the outlet sound mouth 2 in described casing 1 front is arranged with the vis-a-vis of described woofer 4.The both sides of described framework 3 are also provided with two vertical clapboards 5, described two vertical clapboard 5 one end are fixedly connected with the upper inwall of described casing 1, the other end is suspended on two depressed parts of W type framework 3, in the center of casing 1, framework 3 is set, and be provided with vertical clapboard 5 in framework 3 both sides, make the air damping of the air pressure around woofer 4 and generation be full symmetric, contribute to woofer 4 cone operationally stable, and reach the object of efficiency utilization woofer 4.Casing 1 is divided into multiple cavity be interconnected by framework 3 and vertical clapboard 5, therefore when woofer 4 sends sound wave, air movement in multiple cavity, air molecule is at cavity inner wall multiple reflections and produce resonance, resonant acoustic wave because of multiple reflections intensity strengthened greatly, intensity exceedes the intensity of acoustic wave that woofer 4 sends, the outlet sound mouth 2 of casing 1 communicates with the external world, resonant acoustic wave in chamber is by outlet sound mouth 2 outwards radiative acoustic wave, superimposed to extraradial sound wave with woofer 4, low frequency amount sense after superposition is more sufficient, dynamics is stronger, the LF-response of audio amplifier is made to obtain very large reinforcement, obtain the LF-response of optimization, as shown in Figure 3 and Figure 4, the forward being respectively single loud speaker super low voice box of the utility model preferred embodiment goes out sound spectrogram and side direction goes out sound spectrogram, audio frequency is blazed abroad by the outlet sound mouth in front and the outlet sound mouth in front by the low-frequency sound wave in casing 1, make single loud speaker super low voice box of the present utility model that side direction can be had to lead sound and forward to speak two kinds of working methods, make product more can adapt to on-the-spot different-effect requirement.
Wherein, the volume size of adjustment casing 1 can obtain different LF-response, further, in an execution mode of the present utility model, the width 8-14mm larger than the bore of described woofer 4 of described casing 1, the large 15-25mm of height of woofer 4 described in the aspect ratio of described casing 1, the length of described casing 1 and the ratio of width are 2.5: 1, according to the woofer 4 of different capacity, the number ratios of each size of adjustment casing 1, obtain rational tank-volumes, reach desirable casing resonance low frequency.
The sound of single loud speaker super low voice box of the present utility model produces mainly through described sound superposition, because before and after the vibrating diaphragm of described woofer 4, sound is reverse, can the acoustic waveguide at woofer 4 rear portion extremely close to woofer 4 front, with the sound wave in woofer 4 front at same opening part diffraction out, Downward addition is obtained at sound after described, sound reproduction value is very big, be now maximum to the coupling acoustic resistance of described woofer 4, woofer 4 amplitude is minimum, the utility model list loud speaker super low voice box can export smaller part at the amplitude of described woofer 4 and obtain larger low frequency reproduction, significantly promote the born playback power of conveying woofer 4, thus the low frequency reproduction performance of expansion the utility model list loud speaker super low voice box.
The utility model is installed ingenious for woofer 4 significantly heavy position by utilizing the framework 3 in w type, make single loud speaker super low voice box of the present utility model easily outlet sound mouth 2 to be made in before woofer 4, better the sound wave before and after woofer 4 perfectly in conjunction with utilization.And be provided with outlet sound mouth 2 in the side of casing 1 and front, make single loud speaker super low voice box of the present utility model that side direction can be had to lead sound and forward and to speak two kinds of working methods, make product more can adapt to on-the-spot different-effect requirement.Air-flow in single loud speaker super low voice box of the present utility model follows stream and forms sound wave between framework 3 and vertical clapboard 5, make low-frequency sound wave obtain very large enhancing, outlet sound mouth 2 of the present utility model is provided with two, and is connected with phonocatheter accordingly, when low-frequency sound wave is by phonocatheter, bass is enhanced; Single loud speaker super low voice box volume of the present utility model is little, meets the visual effect of Decoration Design, saves site space.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the claims in the present invention are done, still belong to the scope that the present invention is contained.
