Description
Technical field
The present invention relates to sound-box device technical field, more specifically a kind of casing tuning formula audio amplifier.
Background technology
Audio amplifier is the terminal of whole sound system, and its effect is that audio frequency electric energy is converted into corresponding acoustic energy, and its spoke
It is mapped to space go.Its basic structure includes that casing, core component are placed in the speaker of box house.
Owing to the subjective feeling of sound is evaluated the most important standard that a sound system tonequality is fine or not by human ear just, because of
This, it is believed that the performance height of audio amplifier is to play pivotal role to the playing quality of a sound system.So people think to the greatest extent
The structure of all ways transformation audio amplifier promotes the playing quality of sound box system.
Such as patent CN201010137035.1 describes a kind of audio amplifier, and it includes housing and raising one's voice of being contained in housing
Device and sound cup.Forming sound chamber in described housing, described speaker is used for outside described housing and described sound intracavity sends sound, institute
State and on housing, offer sender, in order to the sound of described sound intracavity is conducted outside housing through described sender.Described housing
On be additionally provided with at least one conduit, one of them conduit connects described sender and sound chamber.Described sound cup cover at described at least
On one conduit, and between described sender and sound chamber, form the sound channel of bending, in order to the sound conduction by sound intracavity
To sender.Described sound cup is provided with at least two dividing plate, and described at least two baffle interval is arranged in sound channel, is used for
Sound channel is separated into the subchannel at least two connection sound chamber and sender.Above-mentioned audio amplifier is by being separated into sound channel
At least two subchannel so that sound resonates in being limited in subchannel, so that audio amplifier sounding is more uniformly distributed.
But, the playing quality of sound box system is also closely bound up from different playing environments, such as the wall in some rooms
Use Sound-proof material Soft Roll, then it is many for the absorption of middle bass, and sound can be the cleanest；The wall in some rooms for another example
Using hard ceramic tile with ground, then it is few for the absorption of middle bass, major part is reflected, tone color sensation muddiness.As above
Two kinds of situations ultimately cause human ear and experience the effect of audio amplifier and just have larger difference, and in a word, the playing quality of sound box system is poor.
Summary of the invention
It is an object of the invention to make up more than prior art not enough, it is provided that a kind of machinery tuning, with low cost, power consumption
The casing tuning formula audio amplifier that little, stable performance, playing quality effectively get a promotion for playing environment.
In order to reach object above, the present invention is achieved by the following technical solutions: a kind of casing tuning formula audio amplifier, bag
Include casing, and be placed in the speaker on described box house front side wall and the wiring board on rear wall, it is characterised in that be described
On casing, in the circulating loudspeaker circumference sidewall of a week, at least one is set to double-deck cavity wall, and described double-deck cavity wall is by inner chamber
Wall and outer chamber wall are separated out sound channel and constitute, and described sound channel is set to opening port on the rear wall of described casing,
Offer at least one on described internal chamber wall in the horizontal direction and cross sound groove, the diapire of described casing is provided with a bearing, described
Being provided with a screw mandrel on bearing, described screw mandrel is arranged side by side with crossing sound groove, and described screw mandrel is arranged with one with thread fiting mode
Advance and retreat slide block, described advance and retreat slide block carries before and after one port and can be coated on the tuning to the periphery of described speaker week
Frame, described screw mandrel connects a drive mechanism.
The present invention is rotated by screw mandrel rotating and tuning frame is moved forward or rearward, thus realizes tuning frame to crossing sound
Completely obscured, fractional open, the wide-open Regulation in all life process of groove, closes the gradual change of case to unpacking or unpacking reaching to close case
Journey, how many to realize Mechanical course volume, when closing case, tonequality speed rhythm is fast, sound compacts, and when unpacking tonequality speed
Rhythm is slow, sound is loose.Thus preferably for different playing environments, adjust intermediate frequency and the adaptive acoustical quality of low frequency, it is achieved
Playing quality effectively gets a promotion for playing environment.
As preferably, described wherein one end crossing sound groove is positioned at the position of side wall handing-over front side wall, but described crosses sound groove
Whole length is less than the 70% of whole internal chamber wall transverse width.
Unreasonable more than in 70% structure, and tuning frame also cannot reset.And opened sound slot length completely can cause
Sound failure of adjustment, must stay a part to cover sound after casing.
As preferably, before and after tuning frame, port depth was not more than the whole length of sound groove.
The when that tuning frame sliding into the end backward, it crosses sound groove just close to Full-open state, then plays toward front slide and covers
Cross the effect of sound groove.Tuning frame can make full use of length tuning, will not wasting space.It is not easy to affect tuning effect
As preferably, described sound groove of crossing is in-line.
Cross that the shape design of sound groove plays is the change of product style, and the relation for its shape Yu tuning is it on the contrary
The decisive role that area plays is some larger, even if sound channel is the least greater than sound groove more conversely speaking, then the effect of regulation
Fruit is also small, and vice versa, so the penetrating area and to match and be preferred of the area of section of sound channel and mistake sound groove.
As the alternative of such scheme, described sound groove undulate excessively.Ibid resolve.
As the alternative of such scheme, described sound groove of crossing is round shape.Ibid resolve.
As preferably, connecting and have some reinforcements between corresponding internal chamber wall and outer chamber wall, some reinforcements are by right
If answering sound channel to be separated out arterial highway branch out sound passage, per pass branch sound channel correspondence is assigned at least one and is arranged at internal chamber wall
On cross sound groove.
In order to ensure the intensity of double-deck cavity wall, sound channel is set up reinforcement, it is ensured that the intensity of whole casing.It is again
Ensure that per pass branch sound channel all plays tuning effect, so it is the most indispensable to cross sound groove.
As preferably, described drive mechanism is a knob, and described knob is arranged on the outer surface of described casing rear wall.
The scheme that knob drives screw mandrel to rotate is pure craft, and advantage is with low cost, it is simple to maintenance, shortcoming is that product is low
End, troublesome poeration, laborious.
As the alternative of such scheme, described drive mechanism is a clockwise and anticlockwise motor, described clockwise and anticlockwise motor and line
Rotating control knob on the plate of road is connected.
The scheme that clockwise and anticlockwise motor drives screw mandrel to rotate is mechanical automation, and advantage is that product is high-end and atmospheric, operation side
Just, laborsaving, shortcoming is that cost is high.
As preferably, bearing has been arranged in parallel with screw mandrel same level in the both sides of screw mandrel a pair slide bar, retreats sliding
Block wears this to slide bar while wearing screw mandrel.
So that tuning is frameed shift dynamic more steady, install relatively reliable, carry out auxiliary by a pair slide bar and support.
Beneficial effect: the present invention, preferably for different playing environments, adjusts intermediate frequency and the adaptive acoustical quality of low frequency, real
Existing playing quality effectively gets a promotion for playing environment.
