Description
Technical field
?the utility model relates to a kind of loudspeaker box structure, especially a kind of wooden acoustic box structure.
Background technology
audio amplifier is the terminal of whole sound system, and its effect is that audio frequency electric energy is converted to corresponding acoustic energy, and it is radiated space.It is the extremely important part of sound system, the signal of telecommunication is transformed into acoustical signal directly listens to so mission critical because which is responsible for the ear of people, it is wanted directly and the sense of hearing of people is come into contacts with, and the sense of hearing of people is very sensitive, and to the tone color of complex sound, there is very strong resolving ability.Because people's ear to evaluate the most important standard of a sound system tonequality quality just to the subjective feeling of sound, therefore, can think, the performance height of audio amplifier plays key effect to the playing quality of a sound system.
At present, comprise high, medium and low three kinds of loudspeaker in audio amplifier, and the collocation of various loudspeaker and position distribution are all the key factors affecting audio amplifier tonequality.The air-flow that the internal structure of the bass effect of audio amplifier and the size of loudspeaker and audio amplifier causes moves towards much relations.Now in order to improve bass effect, be all often the size expanding loudspeaker, the audio amplifier volume causing bass effect good is also larger.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of loudspeaker box structure, by arranging symmetrical air-flow guide channel in audio amplifier, effectively improves bass effect.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of loudspeaker box structure, comprise casing, casing front end face is embedded with loudspeaker, mediant trumpet and control panel, power amplifier is provided with in casing, in described casing centered by power amplifier, be symmetrically arranged with bass horn in the left and right sides of this power amplifier, the sounding mouth of this bass horn is towards tank floor, and casing is provided with venthole.
Be provided with containing cavity in described casing, bass horn is arranged in this containing cavity.
In described casing centered by power amplifier, be symmetrically arranged with air-flow guide channel in the left and right sides of this power amplifier, this air-flow guide channel is connected with venthole.
Described air-flow guide channel is made up of the multiple baffle plates be installed in casing.
Described baffle plate is with rule or irregular mode arranged distribution.
Be provided with the middle pitch region annular seal space being positioned at mediant trumpet region in described casing, this middle pitch region annular seal space is connected with mediant trumpet, containing cavity and air-flow guide channel.
Also be provided with the control panel annular seal space being positioned at control panel region in described casing, this control panel annular seal space communicates with power amplifier region.
The utility model by setting out pore on casing, and in casing, be symmetrical arranged air-flow guide channel (labyrinth structure form), allow air-flow in order in flowing, and by processing, the seal of casing and structural strength are improved, make air in limited height space can concentrate very much to pilot hole flowing and produce airflow, under high-power current signal drives loudspeaker brute force, horn basin significantly shakes the low frequency air-flow of generation and the casing DTH hammer bit under the low frequency that produces that resonates and passes to ground, ground is made to produce the sensation of slight earthquake, effective raising bass effect.
Accompanying drawing explanation
Accompanying drawing 1 is overlooked for the utility model and is cut structural representation open;
Accompanying drawing 2 is the main TV structure schematic diagram of the utility model;
Accompanying drawing 3 looks up structural representation for the utility model.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in accompanying drawing 1,2 and 3, the utility model discloses a kind of loudspeaker box structure, comprise casing 1, casing 1 front end face is embedded with loudspeaker 2, mediant trumpet 3 and control panel 4, be provided with power amplifier in casing 1, in described casing 1 centered by power amplifier, be symmetrically arranged with bass horn 5 in the left and right sides of this power amplifier, the sounding mouth of this bass horn 5 is towards casing 1 bottom surface, and casing is provided with venthole 6.Under normal circumstances, centered by the position of power amplifier, just control panel 4 is installed to the casing front end face region of power amplifier, this control panel 4 bilateral symmetry arranges mediant trumpet 3 and the loudspeaker 2 of same quantity, in the present embodiment, control panel both sides are provided with two mediant trumpets, 3, loudspeaker 2 and a venthole 6 separately.In casing 1, be provided with containing cavity 7, bass horn is arranged in this containing cavity, and this containing cavity can be installed by sheet material and form, in bass horn is arranged on.
In casing 1 centered by power amplifier, be symmetrically arranged with air-flow guide channel 8 in the left and right sides of this power amplifier, this air-flow guide channel 8 is connected with venthole 6.Air-flow guide channel 8 is made up of the multiple baffle plates 9 be installed in casing.Baffle plate 9 with regular fashion arranged distribution, or with irregular mode arranged distribution.Multiple baffle plate installs arrangement in casing, makes to be formed in casing to be similar to " labyrinth " formula structure, and ensures that the structure of the both sides of power amplifier is consistent, and the air-flow enabling air-flow guide channel guide casing inside trumpet to produce, makes to flow to venthole in air flow collection.
In addition, be provided with the middle pitch region annular seal space 10 being positioned at mediant trumpet 3 region in casing 1, this middle pitch region annular seal space 10 is connected with mediant trumpet 3, containing cavity 7 and air-flow guide channel 8.Also be provided with the control panel annular seal space 11 being positioned at control panel 4 region in casing 1, this control panel annular seal space communicates with power amplifier region.
During the utility model design, the centre frequency of loudspeaker is strictly mated with the equivalent volume of casing, realize resonance, the huge energy of generation is passed to ground.By arranging the air-flow guide channel of symmetrical maze-type structure in casing, and under adopting CNC machining center to guarantee the condition of machining accuracy, the seal of casing and structural strength are maximized, while making the air-flow olderly flowage in casing, what in limited cabinet space, air-flow can be concentrated very much flows to venthole through air-flow guide channel, thus generation airflow, under high-power current signal drives the brute force of loudspeaker, horn basin significantly shakes the low frequency air-flow of generation and the casing potentiality under the low frequency that produces that resonate and passes to ground, effective lifting bass effect.
