Abstract
The utility model discloses a novel waveguide tube sound box. The novel waveguide tube sound box comprises a loudspeaker connected to one end of an S-shaped waveguide tube, the loudspeaker is formed by the vertical arrangement of a neodymium magnetic wave voice unit and a voice coil paper cone unit, and the other end of the S-shaped waveguide tube is connected with an audio waveguide tube. According to the novel waveguide tube sound box, a special design mode that the waveguide tube is connected to the front surface of the loudspeaker is adopted, sound waves generated in front of and at the back of a diaphragm of the loudspeaker is fully used, and medium and high frequency sounds are raised.
Description
Technical field
The utility model relates to a kind of waveguide audio amplifier.Be specifically related to novel waveguide pipe audio amplifier.
Background technology
The vibrating diaphragm of loud speaker, has papery, also has special plastic material, and let it be, and what material is, loud speaker is in the time of work, and vibrating diaphragm will ceaselessly seesaw, and promotes air, and then vibration is imported into people's ear, make people hear sound.Common phase inverted cabinet is the diaphragm of loudspeaker sounding that is exposed, and the rear of loud speaker also has vibration, if rearward loud speaker vibration is also used, will make sound wave strengthen, supper bass is strengthened, after waveguide is installed, because the diameter of waveguide is less than loud speaker diameter, go out from waveguide so just have more intense sound wave, so, loud speaker has forwards all obtained utilization with rearward sound wave, and the raising of audio amplifier tonequality and sound pressure level all can be increased substantially.
Utility model content
The purpose of this utility model is to provide a kind of novel waveguide pipe audio amplifier, by adopting, waveguide pipe is connected in to the particular design mode before loud speaker, makes full use of the sound wave occurring before and after the vibrating diaphragm of loud speaker, has improved medium-high frequency sound.
In order to achieve the above object, the utility model has following technical scheme:
Novel waveguide pipe audio amplifier of the present utility model, comprises the loud speaker that is connected in S shape waveguide pipe one end, and described loud speaker is arranged above and below and is formed by neodymium magnetic wave sound unit and voice coil loudspeaker voice coil cone unit, and the described S shape waveguide pipe other end is connected with audio frequency waveguide pipe.
Further, described S shape waveguide pipe is positioned at loud speaker front.
Further, described audio frequency waveguide pipe is made up of 22 audio frequency waveguide pipe unit.
Owing to having taked above technical scheme, the utility model has the advantage of:
1, box volume small volume and less weight;
2, the raising of audio amplifier tonequality and sound pressure level all increase substantially;
3, medium-high frequency sound is strong.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, S shape waveguide pipe, 2, audio frequency waveguide pipe, 3, loud speaker, 4, neodymium magnetic wave sound unit, 5, voice coil loudspeaker voice coil cone unit
Embodiment
Below implement to be used for illustrating the utility model, but be not used for limiting scope of the present utility model.
Referring to Fig. 1, the utility model comprises the loud speaker 3 that is connected in S shape waveguide pipe 1 one end, described S shape waveguide pipe 1 is positioned at loud speaker 3 fronts, described loud speaker 3 is arranged above and below and is formed by neodymium magnetic wave sound unit 4 and voice coil loudspeaker voice coil cone unit 5, described S shape waveguide pipe 1 other end is connected with audio frequency waveguide pipe 2, and described audio frequency waveguide pipe 2 is made up of 22 audio frequency waveguide pipe unit.
One, the calculating of waveguide pipe:
Basic ideas: get waveguide pipe sectional area S=0.1～0.4 times bass horn and effectively vibrate area, the larger low frequency radiation-efficiency of area is higher, but length of tube can be longer; Waveguide pipe length L=c × c × S/(4 × circumference ratio × circumference ratio × f × f × V)-0.82 radical sign S(unit is all with centimetre calculating) the c=34400cm/s(velocity of sound wherein), f is the resonance frequency of bass horn, and V is the speciality pvc pipe (better also can) of getting external diameter 40mm<D<60mm about casing dischargeable capacity.
Two, audio amplifier design feature:
Box volume is larger, and low frequency dive is just darker, and Q value declines thereupon; But it is just feeble to have crossed low frequency, now should in audio amplifier, throw away sand hill; Box volume is less, and low frequency dint degree is better, and Q value rises thereupon, but the resonance frequency of relative audio amplifier will rise, and now can add multiple spot sponge to expand inner product again; Waveguide pipe is longer, and the transient response of audio amplifier is just better, low frequency dive simultaneously also darker (inexcessive sense can diminish) still long sound to trail, cause transient response variation again, if what waveguide pipe was long and casing inner plate surface leans on is too near, also can produce airflow noise, this is intolerable; Waveguide pipe is shorter, and transient response is just poorer, resonance frequency also will rise (but amount sense can increase).
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all execution modes.Everyly belong to apparent variation or the still row in protection range of the present utility model of variation that the technical solution of the utility model extends out.
