Abstract
The utility model relates to a loudspeaker box, which comprises a box proper, the face of the box proper is provided with a loudspeaker which is electrically connected with a frequency dividing circuit board in an inner chamber of the box proper, the box proper is made from glass, a horizontal glass plate, which is bent towards the inner chamber of the box proper, is arranged at the lower section on the face of the glass box proper, the inner chamber under the horizontal glass plate forms an echo chamber; the rigidity of the glass box proper is more solidified than that of a wooden box or a medium density plate box; basically no vibration and ''box noise'' produced can interfere with the original sound from loudspeaker, and the sound quality is pure and desirable after an sound hole on the box proper is changed into the echo chamber.
Description
Technical field
The utility model relates to a kind of audio amplifier.
Background technology
As everyone knows, whether the quality of audio amplifier will directly to influence sound dulect.A desirable audio amplifier, its casing should be rigid structures, and when the loud speaker sounding, casing should not vibrate, in order to avoid generation sound dyes.But traditional sound box, the overwhelming majority makes of plank or medium-density plate, its drawback is: the rigidity deficiency of sound box, when the loud speaker sounding, very easily vibrate, produce " case sound ", the primary sound that disturbs loud speaker to send makes tonequality become bad, and people sound that sound is impure, the sense of mixing is arranged.
Summary of the invention
The purpose of this utility model provides the pure audio amplifier of a kind of tonequality.
In order to realize above-mentioned purpose, the audio amplifier that is provided, comprise casing, loud speaker is equipped with in the front of casing, loud speaker is electrically connected with the frequency dividing circuit plate formation that is contained in cabinets cavity, its design feature is that casing is the glass casing, at the front of glass casing lower position the one horizontal glass plate body to the cabinets cavity bending is arranged, and the inner chamber that is positioned at this horizontal glass plate body below constitutes the echo chamber.
Above-mentioned loud speaker includes high pitch loudspeaker, Squawker and woofer.
When installing and using, the frequency dividing circuit plate is electrically connected with the output formation of power amplifier by binding post.
Audio amplifier provided by the utility model, because casing is the glass casing, compare with plank casing or medium-density plate casing, rigidity strengthens greatly, when the loud speaker sounding, do not produce vibration basically, do not have the primary sound that " case sound " disturbs loud speaker to send, also because the echo hole on the casing is become the echo chamber, therefore tonequality is pure, melodized.
Description of drawings
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings, wherein;
Fig. 1 is the structural representation of the described audio amplifier of embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1 is casing, and 2 are loud speaker: 2-1 wherein is that high pitch loudspeaker, 2-2 are that Squawker, 2-3 are woofers, and 3 is the frequency dividing circuit plate, and 4 is horizontal glass plate body, and 5 are the echo chamber, and 6 is lead, and 7 is binding post.
Embodiment
With reference to accompanying drawing, the described audio amplifier of embodiment, comprise casing 1, loud speaker 2 is equipped with in the front of casing 1, loud speaker 2 includes high pitch loudspeaker 2-1, Squawker 2-2 and woofer 2-3, loud speaker 2 is electrically connected with frequency dividing circuit plate 3 formations that are contained in cabinets cavity by lead 6, frequency dividing circuit plate 3 is provided with binding post 7, so that be connected with the output of power amplifier by relevant lead in use, casing 1 is the glass casing, at the front of glass casing lower position the one horizontal glass plate body 4 to the cabinets cavity bending is arranged, the inner chamber that is positioned at these horizontal glass plate body 4 belows constitutes echo chamber 5.
