Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
As shown in figure 1, a kind of novel low-frequency provided by the utility model strengthens audio amplifier, which includes the first casing 1 and interior
The second casing 2 of the inside of the first casing 1 is embedded in, the front panel 11 of the first casing 1 is provided with speaker 3, and the second casing 2 is provided with
Speak passage 21, the outlet sound mouth 211 of passage 21 of speaking connects the front panel 11 of the first casing 1, the second casing 2 is provided with low frequency increasing
Intensity device.
Embedded double-tone box structure form is adopted as the novel low-frequency strengthens audio amplifier, so can be on the second casing 2
Low-frequency enhancement devices are set, strengthen the bass effect of audio amplifier to strengthen the novel low-frequency；Meanwhile, strengthen audio amplifier with traditional low frequency
Structure is compared, as the second casing 2 is embedded in the inside of the first casing 1, so the novel low-frequency strengthens the box sizes of audio amplifier
It is less.
So, due to adopting embedded double-sound box structure form so that can arrange on casing can more produce it is low
The device of yupin effect, i.e. the novel low-frequency strengthens audio amplifier and not only can reduce box sizes, but also can strengthen the low of audio amplifier
Yupin effect.
Low-frequency enhancement devices include at least two passive radiators 4, and passive radiator 4 is distributed in the side wall of the second casing 2
On.
Wherein, passive radiator 4 includes vibrating diaphragm and ring, and vibrating diaphragm is located at the center position of passive radiator 4, ring position
In the two ends of passive radiator 4, ring is to be connected with the side wall of the second casing 2；So, the passive spoke on low-frequency enhancement devices
Emitter 4 increases the bass vibrating diaphragm area of audio amplifier, when shaking that the passive radiator 4 of sound wave and low-frequency enhancement devices in audio amplifier is constituted
When low frequency occurs resonance, passive radiator 4 efficient can give off low-frequency sound wave to dynamic system, so as to improve whole audio amplifier
LF-response, expands low-frequency range, so as to strengthen the bass effect of audio amplifier.
Second casing 2 can be cuboid, square, cylindrical londspeaker box body structure；Preferably, the second casing 2 is length
Cube or square, now the side wall of the second casing 2 include upper side wall 22, lower wall 23, left side wall (not shown), right side wall
(not shown), rear wall 24.
According to using, the attractive in appearance, needs putting or design, the second casing 2 may be located at the bottom of the first casing 1, now
The passage 21 of speaking of the second casing 2 is positioned at the lower section of speaker 3；Second casing 2 can also be located at the top of the first casing 1, this
When, the passage 21 of speaking of the second casing 2 is positioned at the top of speaker 3.
The present embodiment with the second casing 2 as cuboid, and passage 21 of speaking positioned at the lower section of speaker 3 as a example by illustrating the
The concrete insert structure relation of two casings 2 and the first casing 1：
Due to the second casing 2 for the second casing of cuboid 2 include upper side wall 22, lower wall 23, left side wall, right side wall, after
Side wall 24；Speak what passage 21 can be formed by, i.e. passage 21 of speaking is by upper side wall 22, lower wall 23, left side wall, the right side
Side wall, rear wall 24 are surrounded；Wherein, upper side wall 22 and lower wall 23 are each parallel to plate, left side wall and the right side above the first casing 1
The rear board interval setting of left panel of the side wall each parallel to the first casing 1, the rear wall 24 of the second casing 2 and the first casing 1；
Due to there is spacing between the side wall and the first casing 1 of the second casing 2, the sound wave that the rear portion of speaker 3 produces can be prompt quickly
Efficiently transmitted in the inner chamber of the first casing 1, and on the passive radiator 4 being radiated on low-frequency enhancement devices, so as to
Prevent audio distortions；Then there is resonance with the vibrational system of the composition of passive radiator 4 of low-frequency enhancement devices in low frequency in sound wave,
Passive radiator 4 efficient can give off low-frequency sound wave, and in the process, the passive radiator 4 of low-frequency enhancement devices can be with
The LF-response of whole audio amplifier is improved, low-frequency range is expanded, so as to strengthen the bass effect of audio amplifier.
Preferably, on the second casing 2, low-frequency enhancement devices include 2N passive radiator 4, and N is positive integer, such that it is able to
According to needs are used, the number of passive radiator 4 is flexibly set on the second casing 2, meet user and audio amplifier bass is imitated
The use requirement of fruit；When needing to make audio amplifier reach optimal bass effect, nothing can be set as much as possible in the second casing 2
Source radiation device 4, to increase the area of audio amplifier bass vibrating diaphragm to greatest extent, makes the bass effect of audio amplifier optimal；2N passive spoke
Emitter 4 is uniformly and symmetrically distributed on the upper side wall 22 and lower wall 23 of the second casing 2, so that speaker 3 operationally can be same
When drive top and bottom sidewall 23 on passive radiator 4 resonated, then, through passive radiator 4 promote low-frequency sound wave lead to
The outlet sound mouth 211 for crossing passage 21 of speaking is spread out of outside sound box, so that the bass effect of audio amplifier is greatly enhanced.
As the medium-high frequency sound wave that the speaker 3 on the front panel 11 of the first casing 1 sends is direct radiation in air
, so the reproduction quality of the medium-high frequency of audio amplifier can be guaranteed.Therefore, novel low-frequency enhancing audio amplifier can install osculum
The speaker 3 in footpath, is substantially reduced so not only can enclosure size, and can also realize gratifying bass effect.
Preferably, low-frequency enhancement devices include four passive radiators 4, four passive radiators 4 be uniformly and symmetrically distributed in
On the upper side wall 22 and lower wall 23 of the second casing 2, so can be in the case where fully sound box size be reduced, maximum limit
Surface area of the degree ground using the second casing 2, so that the bass effect of audio amplifier reaches most preferably；
But, when the size of audio amplifier is less, and make the upper side wall 22 and 23 surface area of lower wall of the second casing 2 less and nothing
When method installs multiple passive radiators 4, low-frequency enhancement devices can only include two passive radiators 4, the two passive radiations
Device 4 is symmetrically distributed on upper side wall 22 and lower wall 23, and so arranging produces can the passive radiator 4 on top and bottom sidewall 23
Low-frequency sound wave resonated so that the bass effect of audio amplifier is strengthened, compare so as to the bass effect for ensureing audio amplifier reaches
Preferable scope.
In order that the low-frequency sound wave that passive radiator 4 is produced can produce resonance well, and also to convenient install
And detachable maintaining, number of assembling steps can be simplified and maintenance difficulty and cost, 4 electrical parameter of multiple passive radiators and size is reduced
It is identical.
To sum up, a kind of novel low-frequency of the present utility model strengthens audio amplifier, due to the structure shape using embedded double-tone case
Formula, the novel low-frequency strengthen the size that audio amplifier not only can reduce casing, but also can strengthen the low-frequency effect of audio amplifier.
The above is only preferred implementation of the present utility model, it is noted that for the ordinary skill people of the art
Member for, on the premise of without departing from this utility model know-why, some improvement and replacement can also be made, these improve and
Replacement also should be regarded as protection domain of the present utility model.
