Description
Technical field
The utility model relates to the technical field of audio output apparatus, particularly relates to a kind of hyperline type list speakers low frequencies audio amplifier.
Background technology
As everyone knows, at the society of electroacoustic techniques fast development, the requirement for various sound reinforcement system is more and more higher, when various amusement, on-the-spot demonstration and audio replay.Wherein, as the bass of expressing sound or music dynamics and basis, the sound equipment replay effect at whole scene is directly had influence on.Particularly during remote public address, in order to the low-frequency effect obtained, many Sound design persons from loudspeaker box structure painstakingly, the casing of invention and design different structure, the professional requirement to bass Long Distant Transmit is reached with this, but it is large that this type of audio amplifier existing is all complex structure manufacture difficulty, and larger on loudspeaker enclosure impact.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of effect reaching the replay of good low frequency and Long Distant Transmit, the hyperline type list speakers low frequencies audio amplifier of the low-frequency effect that remote audition scene has been reached.
Hyperline type list speakers low frequencies audio amplifier of the present utility model, comprise casing, the inside of casing is provided with chamber, and dividing plate is horizontally arranged with in chamber, chamber is divided into the first resonance chamber and the second resonance chamber, described first resonance chamber is positioned at the top of the second resonance chamber, described dividing plate is provided with through hole, described first resonance chamber and the second resonance chamber are communicated by through hole, described casing is provided with speaker hole, described speaker hole is arranged on the wallboard of the first resonance chamber, one end of described loud speaker is arranged on speaker hole place, one side communicates with casing space outerpace, the another side of described loud speaker communicates with the first resonance chamber, be provided with in described second resonance chamber and organize baffler more.
Hyperline type list speakers low frequencies audio amplifier of the present utility model, described baffler is in casing paraphase exit, and baffler is laterally equidistantly arranged in described second resonance chamber.
Hyperline type list speakers low frequencies audio amplifier of the present utility model, loud speaker rear portion sound wave is successively by two resonator chamber, and the paraphase mouth afterwards through being equipped with baffler gives off the sound wave consistent with loud speaker front phase place.
Compared with prior art the beneficial effects of the utility model are: by above-mentioned setting, by above-mentioned setting, can reach the effect of the replay of good low frequency and Long Distant Transmit, make the low-frequency effect that remote audition scene has reached.

Fig. 3 is right view of the present utility model;
Fig. 4 is front view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figures 1 to 4, hyperline type list speakers low frequencies audio amplifier of the present utility model, comprise casing 1, the inside of casing is provided with chamber, and in chamber, be horizontally arranged with dividing plate 2, chamber is divided into the first resonance chamber 3 and the second resonance chamber 4, first resonance chamber is positioned at the top of the second resonance chamber, dividing plate is provided with through hole 5, first resonance chamber and the second resonance chamber are communicated by through hole, casing is provided with speaker hole 6, speaker hole communicates with the first resonance chamber, and loud speaker 7 is provided with in the first resonance chamber, one end of loud speaker is arranged on speaker hole place, the other end of loud speaker communicates with the first resonance chamber, the other end is towards the space outside casing.Many group bafflers 8 are provided with in second resonance chamber; By above-mentioned setting, the effect of the replay of good low frequency and Long Distant Transmit can be reached, make the low-frequency effect that remote audition scene has reached.
Hyperline type list speakers low frequencies audio amplifier of the present utility model, baffler is in casing paraphase exit, and baffler is four groups, and four groups of bafflers are laterally equidistantly arranged in the second resonance chamber.Farthest can to reduce in paraphase mouth flow-disturbing to the impact of sound wave.
Hyperline type list speakers low frequencies audio amplifier of the present utility model, loud speaker rear portion sound wave is successively by two resonator chamber, and the paraphase mouth afterwards through being equipped with baffler gives off the sound wave consistent with loud speaker front phase place.
Hyperline type list speakers low frequencies audio amplifier of the present utility model, have employed the design of secondary resonance paraphase, the sound wave at loud speaker rear portion produces first time resonance in the first resonance chamber, enter the second resonance chamber by main humorous through hole and carry out secondary resonance, and the pectination paraphase mouth be made up of baffler, give off the high pressure sound wave that sound anterior with loud speaker is consistent, reach high efficiency and at a distance low-frequency sound wave is radiate; Utilize the volume of the first resonance chamber, the performance number of loud speaker, draw the volume numerical value of the second resonance chamber, then after determining the air pressure ratio needed for the first resonance chamber to the second resonance chamber, draw numerical value.Obtain the rational resonance opening of the first resonance chamber, reach desirable casing resonance low frequency.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
