Abstract
The utility model discloses a kind of audio amplifier, comprise casing, at least two woofers, leading note pipeline and high pitch loudspeakers, described at least two woofers, leading note pipeline and a high pitch loudspeaker are all arranged in described casing, described leading note pipeline offers sound guide tube road sound mouth on described casing, the same side of at least two woofers described in described sound guide tube road sound mouth is positioned at.The sound guide tube road sound mouth setting position of audio amplifier of the present utility model is reasonable, does not affect the tonequality of audio amplifier, and the audio amplifier volume required when settling onesize loudspeaker unit is less, decreases space hold.
Description
Technical field
The utility model relates to a kind of audio amplifier.
Background technology
Audio amplifier is a kind of voice output facility, generally comprises high pitch loudspeaker and woofer, and what have is also furnished with two and plural woofer, and there is the leading note pipeline guiding sound trend the inside of audio amplifier.Leading note pipeline generally has opening as sound guide tube road sound mouth on audio amplifier, and high bass is better mixed.Current audio amplifier as shown in Figure 1, the sound guide tube road sound mouth 4 of prior art be all be generally arranged on two prior aries woofer 6 between, the sound guide tube road sound mouth 4 of prior art is arranged vertically with the high pitch loudspeaker 7 of prior art, the woofer 6 of two prior aries has been separated, reduce the tonequality of audio amplifier, but also adding the volume of audio amplifier, the audio amplifier volume required when settling onesize loudspeaker unit is larger, increases space hold.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of audio amplifier, the sound guide tube road sound mouth setting position of this audio amplifier is reasonable, do not affect the tonequality of audio amplifier, the audio amplifier volume required when settling onesize loudspeaker unit is less, decreases space hold.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of audio amplifier, comprise casing, at least two woofers, leading note pipeline and high pitch loudspeakers, described at least two woofers, leading note pipeline and a high pitch loudspeaker are all arranged in described casing, described leading note pipeline offers sound guide tube road sound mouth on described casing, the same side of at least two woofers described in described sound guide tube road sound mouth is positioned at.
In the utility model preferred embodiment, described sound guide tube road sound mouth is parallel with described high pitch loudspeaker.
In the utility model preferred embodiment, described sound guide tube road sound mouth is identical apart from the distance of described at least two woofers.
The beneficial effects of the utility model are: the sound guide tube road sound mouth setting position of audio amplifier of the present utility model is reasonable, does not affect the tonequality of audio amplifier, and the audio amplifier volume required when settling onesize loudspeaker unit is less, decreases space hold.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the audio amplifier of prior art;
Fig. 2 is the structural representation of audio amplifier of the present utility model.
In accompanying drawing, the mark of each parts is as follows: 1, woofer, and 2, high pitch loudspeaker, 3, sound guide tube road sound mouth, 4, the sound guide tube road sound mouth of prior art, 5, casing, 6, the woofer of prior art, 7, the high pitch loudspeaker of prior art.
Embodiment
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 2, the utility model embodiment comprises:
A kind of audio amplifier, comprise casing 5, at least two woofers 1, leading note pipeline and a high pitch loudspeaker 2, described at least two woofers 1, leading note pipeline and a high pitch loudspeaker 2 are all arranged in described casing 5, described leading note pipeline offers sound guide tube road sound mouth 3 on described casing 5, the same side of at least two woofers 1 described in described sound guide tube road sound mouth 3 is positioned at.
Preferably, described sound guide tube road sound mouth 3 is parallel with described high pitch loudspeaker 2.
Preferably, described sound guide tube road sound mouth 3 is identical apart from the distance of described at least two woofers 1.
Leading note pipeline and sound guide tube road sound mouth 3 are arranged on the same side of casing 5, do not push up the edge up and down of trunkful body 5, avoid leading note pipeline and two woofers 1 are separated, can not affect audio amplifier tonequality.
In addition, the such topology layout of sound guide tube road sound mouth 3 also makes the compact conformation of casing 5, the spacing of two woofers 1 can be less, settle the onesize box volume needed for loudspeaker unit less, or same casing can settle larger loudspeaker unit, be conducive to meeting customer requirement.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
