Abstract
The utility model relates to a small size sound box matched with a small size bass box. The utility model is composed of two loudspeakers and a box body of the sound box, wherein, the shape of a mouth of one loudspeaker is approximately elliptical, the length of a short shaft of the ellipse is equal to 1.8-2.2 inches, and the length of a long shaft is equal to 3.5-4.5 inches. The other loudspeaker is a high pitch loudspeaker. The width of the inner part of the box body of the sound box is equal to the size of the short shaft, and the height of the inner part of the box body of the sound box is equal to the total size of the long shaft and the height of the high pitch loudspeaker. The utility model has the advantages that two small size sound boxes of the utility model are matched with a small size bass box to form a high fidelity stereo sound active sound box, and stereo sound of high fidelity can be played in small space.
Description
The utility model relates to a kind of little audio amplifier, and the little audio amplifier that especially a kind of and small-sized super bass box is supporting is the stereo set field.
In the market, for portable laser phonograph, walkman, the various little audio amplifier style that the computer multi-media playback is used is a lot, all is mostly to use circular loudspeakers, no matter places 1 or 2 loud speakers in the audio amplifier, if want the words of acoustic frequency response wider range, then certainly will to there be a loud speaker bore bigger, thereby increases the width of audio amplifier, be not easy on writing desk or computer desk, place.Though the little audio amplifier that also useful on the market elliptical loudspeaker is done has at least in the audio amplifier in a pair of left and right acoustic channels audio amplifier to keep battery and amplifying circuit, so the volume of audio amplifier is still bigger, and playback effect is also undesirable.
The utility model applicant proposed in number of patent application 95236056.X once that a kind of and small-sized 3D is stereo to form the little audio amplifier of small-sized left and right acoustic channels of small-sized 3D stereo reproducing system with super bass box, emitting clear stereo with small-sized 3D stereo reproducing system in less space.It is oval-shaped 2 * 3.5 inches loud speakers that this little audio amplifier has been used a degree of lip-rounding, thereby can take into account alt acoustic frequency response.Through repeatedly practice, realize not to be that a lot of loud speaker factory can both make this kind loudspeaker high frequency reach 20,000Hz's, when adopting this kind loud speaker of certain some factory, high pitch is still felt shortcoming a bit.
The purpose of this utility model provides the little audio amplifier of left and right acoustic channels of the supporting composition active audio amplifier of a kind of and small-sized super bass box, emitting clear stereo with this active audio amplifier in less space.When the circuit of its active audio amplifier has surround sound output, can also dispose 2 so little audio amplifiers again, serve as the surround channel audio amplifier therein.
The purpose of this utility model can reach by the following technical programs: a kind of little audio amplifier is made up of 2 loud speakers and sound box, the degree of lip-rounding of one of them loud speaker is a sub-elliptical, and its oval minor axis is long to be (1.8～2.2) inch, its major axis is long to be (3.5～4.5) inch, and another is a high pitch loudspeaker.The inner width and the minor axis dimension of sound box match, and the height that the interior height of sound box and major axis dimension add high pitch loudspeaker matches.Here, the loud speaker of sub-elliptical is served as audio frequency by 150Hz～12, and 000Hz is main playback, and high pitch loudspeaker is then served as audio frequency by 12,000～20, and 000Hz is main playback.Cabinets cavity has only 12 * (3.5～4.5) inch loud speaker and 1 high pitch loudspeaker, and connecting line, need connect electric capacity or the adjunction filter circuit except the high pitch loudspeaker of some plant produced, not contain other electronic devices and components, in casing, more not have audio amplifier circuit.
In above-mentioned technical solution, the material of casing can be plastics, timber or paper material.
Description of drawings is as follows
The side cutaway view of a kind of embodiment of the little audio amplifier of Fig. 1 the utility model
The top plan view of a kind of embodiment of the little audio amplifier of Fig. 2 the utility model
The front view of 2 * 3.5 inches loud speakers among Fig. 3 the utility model embodiment
A kind of embodiment outside drawing of little audio amplifier of Fig. 4 the utility model and the supporting composition clear stereo of small-sized super bass box active audio amplifier
The utility model is described in further detail below in conjunction with drawings and Examples:
The little audio amplifier of the utility model is made up of loud speaker and sound box, as the embodiment of Fig. 1 side cutaway view and Fig. 2 top plan view, 2 loud speakers is arranged in the sound box, and one of them is 2 * 3.5 inches a loud speaker 5, and another is a high pitch loudspeaker 6.Sound box can be by side box plate 1, preceding boxboard 2, and front panel 3, rearing-box plate 4 constitutes, and preceding boxboard 2 clads have baffle cloth.The width of the inner width of sound box and loud speaker 5 matches for 2 inches, and the interior height of sound box and 3.5 inches height that add high pitch loudspeaker 6 of the height of loud speaker 5 match.Here, 2 * 3.5 inches loud speakers 5 are served as audio frequency by 150Hz～12, and 000Hz is main playback, and 6 of high pitch loudspeakers are served as audio frequency by 12,000～20, and 000Hz is main playback.Cabinets cavity has only 12 * 3.5 inches loud speaker 5 and 1 high pitch loudspeaker 6, and connecting line 7, need connect the electric capacity 8 except the high pitch loudspeaker of some plant produced, does not contain other electronic devices and components, does not also have audio amplifier circuit in casing.
In above-mentioned technical solution, the material of casing can be plastics, timber or paper material.
By the front view of 2 * 3.5 inches loud speakers among the embodiment of Fig. 3 as seen, the degree of lip-rounding of 2 * 3.5 inches loud speakers 5 is sub-ellipticals.The frequency response of 2 * 3.5 inches loud speakers, bass can reach the scope of 3.5 inch diameter round mouth shape loud speakers, high pitch can reach the scope of 2 inch diameter round mouth shape loud speakers, the loud speaker of this 2 * 3.5 inches or 2 * 4.5 inches is employed more in television set, therefore, quality is more stable, and price is also inexpensive.
By the embodiment outside drawing of Fig. 4 as seen, 2 so little audio amplifiers 9 and small-sized super bass box 10 supporting composition clear stereo active audio amplifiers.
The little audio amplifier of the utility model has simple in structure, and volume is little, is convenient to make, and with the supporting composition clear stereo of small-sized super bass box active audio amplifier, can emit the stereo sound of high-fidelity in less space with this active audio amplifier.
