Abstract
The utility model relates to a circular full-frequency loudspeaker box. The loudspeaker box is provided with a box body 1, wherein, the box body is provided with a high pitch loudspeaker 2, a middle pitch loudspeaker 3, a low pitch loudspeaker 4 and a frequency divider 5, the outer side of the box body is provided with a connection box 6, and a sound outlet hole 111 is arranged on the box body. The utility model is characterized in that the box body 1 is divided into an upper and a lower sections, wherein, the upper section 11 is a semi-cylinder shape, and the lower section 12 is a cylinder shape. The inner part of the lower section cylinder body is provided with a super low pitch loudspeaker 7, and the bottom of the box body is provided with a super-low pitch outlet hole 121. The utility model has the design of the cylindrical box body, can replay from super low pitch to high pitch, and has the advantages of rich, thick and no turbidity low pitch, bright middle pitch, clear high pitch, high fidelity factor, etc.
Description
Now, the audio amplifier of Shi Yonging mostly is rectangular wooden audio amplifier in the world, is clinohedral and circle though some are also arranged, and all there is following shortcoming in these audio amplifiers: because the cuboid audio amplifier is assembled by the polylith flat board, at memory box parallel baffle is being arranged, and sharp-pointed case angle is being arranged.According to Principles of Acoustics, the case angle of audio amplifier is sharp-pointed more, and it is strong that the peak valley of frequency characteristic changes Shaoxing opera, therefore will produce standing wave in the cuboid audio amplifier.Because the generation of standing wave, the result makes on output acoustic pressure, the frequency characteristic and peak valley occurs.In actual use, also can produce the phenomenon that asophia is clear, tone color is muddy owing to the panel vibration of loud speaker.
The vibrative reason of audio amplifier have following some:
1, because the caused excited vibration of inside standing wave that the loudspeaker enclosure shape is determined.
2, since loud speaker itself, the mounting portion of loud speaker, and the loudspeaker box material interface divides bonding insecurely, wards off the vibration that sound causes thereby produce.Because wooden audio amplifier all is assembled by plank, this vibration meeting is fierce more.
In addition, present audio amplifier all only is equipped with high, medium and low loud speaker, can not realize the sound reproduction of mega bass part, and the low side frequency is difficult to the ultralow frequency of accomplishing that 30Hz is following, does not realize the playback of full frequency-domain.
Recently, also have the audio amplifier of some non-cuboids to occur, disclose two kinds of audio amplifiers as Chinese patent application CN2182503Y and ZL98231176.1, their casing is the garden cylindricality, standing wave is made moderate progress, but still do not realize subsonic playback.
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of cylindrical box design that has is provided, and can both reset from the subwoofer to the high pitch, and bass is abundant, abundant, haze-free, and middle pitch is bright, high pitch is clear, the circular full frequency-domain audio amplifier that fidelity is high.
For achieving the above object, the utility model provides a kind of circular full frequency-domain audio amplifier, and this audio amplifier has a casing 1, and high pitch loudspeaker 2, Squawker 3, woofer 4, frequency divider 5 are housed on the casing, casing is equipped with terminal box 6 outward, casing is provided with sender 111, it is characterized in that, casing 1 is divided into upper and lower two sections, wherein epimere 11 is the semicircle tubular, hypomere 12 is cylindric, and a super woofer 7 is housed in the hypomere cylinder, is provided with subwoofer sender 121 at bottom half.
Described casing 1 is integrated, and is made by pvc material.
Compare with existing various audio amplifiers, the utlity model has following distinguishing feature:
1, audio amplifier of the present utility model adopts cylinder-like structure, does not have the parallel baffle of vertical direction in the casing, does not have sharp-pointed case angle, thereby has eliminated the condition that produces standing wave.
2, casing is integrated, and adopts polyvinyl chloride composite materials to be made, and its rigidity is big, and intensity is enough, has avoided because audio amplifier material stick portion is bonding not firm, splits the caused vibration of sound thereby produce.
1, box house is equipped with subwoofer to the high pitch loud speaker, has realized the audio playback of full frequency-domain, and tonequality is improved greatly, and it is abundant, abundant, haze-free to have a bass, and middle pitch is bright, high pitch is clear, the acoustics that fidelity is high.
2, because casing adopts polyvinyl chloride composite materials to make, thereby can save timber, and reduce cost.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model profile schematic diagram.
Fig. 2 is the utility model structure cutaway view.
As shown in Figure 1 and Figure 2, circular full frequency-domain audio amplifier of the present utility model has a casing 1, this casing is different with existing sound box, it is divided into upper and lower two sections, wherein epimere 11 is the semicircle tubular, hypomere 12 is cylindric, makes one by pvc material for upper and lower two sections, forms integral structure.On the front panel of epimere semicircle tubular casing, high pitch loudspeaker 2, Squawker 3 and bass are housed, loud speaker 4, above-mentioned each loud speaker is all fixed with screw and casing.Frequency divider 5 is housed in the casing, and casing is equipped with terminal box 6 outward, and they are also fixed with screw and casing, and links to each other with each loud speaker by lead.Also be provided with the sender 111 that is used for above-mentioned each loud speaker on the epimere casing.The utility model is also that to the further improvement of existing audio amplifier a super woofer 7 is housed, and this loud speaker flared horn is downward, is screwed on the toroidal membrane 122 in casing in the hypomere cylinder.When super woofer is installed, opens casing bottom 13 it is packed into, again the casing bottom is fixed with screw and casing.Be provided with subwoofer sender 121 on the casing bottom, the mega bass that super woofer sends broadcasts from sender, and through the passage of 14 of bottom and bases to outdiffusion.Owing to be provided with super woofer, make the utility model realize the audio playback of the full frequency-domain from the subwoofer to the high pitch.
