Abstract
The invention discloses a miniature soundbox with a telescopic resonance chamber. The miniature soundbox comprises a loudspeaker, a soundbox upper casing, a soundbox middle casing, a soundbox lower casing, an audio cable, an audio plug, a circuit board, a speaker mesh and the telescopic resonance chamber, wherein the speaker mesh is circular and is connected with the soundbox upper casing, and holes in the speaker mesh are increased gradually from the inside to outside. According to the invention, since the holes in the speaker mesh are increased gradually from the inside to outside, the effects of preventing sundries from damaging a loudspeaker resonance film and protecting the soundbox can be realized, and the sound broadcasting effect is enabled to be better and the sound is broadcast further; in addition, the miniature soundbox is enabled to be more attractive in appearance and an efficacy of protecting the inside loudspeaker is realized; moreover, the noise produced by incompatible resonance can be eliminated, and the sound distortion is restrained to a certain degree.
Description
Technical field
The present invention relates to miniature loudspeaker box field, in particular, relate to a kind of miniature loudspeaker box with flexible resonator.
Background technology
I have applied for a kind of miniature loudspeaker box with flexible resonator and speaker net, number of patent application is 201210295177.X, and this miniature loudspeaker box comprises loudspeaker, audio amplifier upper casing, audio amplifier mesochite, audio amplifier lower casing, tone frequency channel wire, audio jack, circuit board, speaker net and flexible resonator.Audio amplifier upper casing and audio amplifier mesochite connect and fix by inner buckle snap ring, audio amplifier mesochite and audio amplifier lower casing are screwed, tone frequency channel wire is connected with audio jack, circuit board, flexible resonator is positioned at voice box casing, speaker net is positioned at audio amplifier upper casing, and speaker net can play the effect of anti-foreign material damage loud speaker resonating membrane, protection audio amplifier; Also work the effect of protecting inner loudspeaker; And, eliminate the noise that non-harmonious resonance produces, to a certain degree suppressing audio distortions.But general speaker net intercepts the propagation of sound, can not make the farther or better effects if of sound transmission.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of sound transmission better effects and if the farther miniature loudspeaker box of sound transmission.
The object of the invention is to be achieved through the following technical solutions:
A kind of miniature loudspeaker box with flexible resonator, comprise loudspeaker, audio amplifier upper casing, audio amplifier mesochite, audio amplifier lower casing, tone frequency channel wire, audio jack, circuit board, speaker net and flexible resonator, speaker net is circular, speaker net is connected with audio amplifier upper casing, and the hole in described speaker net increases from inside to outside gradually.
Preferably, the hole in described speaker net is outwards to increase round and round, and the hole on described same ring all distributes and be big or small identical.Hole in speaker net is the shape of ring by ring, and equates with the hole on ring, can give people's stereovision and aesthetic feeling like this, and hole increases from inside to outside, so just can relatively make the farther of volume propagation, makes the better effects if of sound transmission.
Preferably, described by the increase gradually from inside to outside of the hole on the same straight line of the speaker net center of circle.Svelteness, easily manufactures like this, and gives people's one aesthetic feeling.
Preferably, described by the increase gradually from inside to outside of the hole on the same straight line of the speaker net center of circle.
Preferably, the hole of described speaker net from the ray in the center of circle is parabolic shape.More attractive in appearance like this.
Preferably, the hole of described speaker net from the ray in the center of circle is parabolic shape.
Preferably, the center of circle of described speaker net is a roundlet, and the hole in described speaker net starts outwards to increase gradually from center of circle roundlet.
Preferably, the center of circle of described speaker net is a real point.Play the effect that strengthens speaker net.
Preferably, increase from inside to outside gradually in the hole on described speaker net ring.Be conducive to like this propagation of sound.
Preferably, in described speaker net, the number in the hole on each ring equates.So easy manufacture.
The present invention is due to the hole in speaker net is arranged to increase gradually from inside to outside, thereby can play the effect of anti-foreign material damage loud speaker resonating membrane, protection audio amplifier, make sound transmission better effects if, propagate farther; In addition, make its effects more attractive in appearance and an inner loudspeaker of protection; And, eliminate the noise that non-harmonious resonance produces, to a certain degree suppressing audio distortions.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the speaker net of the embodiment of the present invention;
Fig. 2 is the schematic diagram of the another kind of speaker net of the embodiment of the present invention.
Wherein: 1, speaker net.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the invention will be further described.
Miniature loudspeaker box with flexible resonator of the present invention, comprise loudspeaker, audio amplifier upper casing, audio amplifier mesochite, audio amplifier lower casing, tone frequency channel wire, audio jack, circuit board, speaker net and flexible resonator, speaker net is circular, speaker net is connected with audio amplifier upper casing, and the hole in described speaker net increases from inside to outside gradually.
Speaker net 1 as shown in Figure 1, speaker net 1 is circular, the center of circle of speaker net 1 is a roundlet, from roundlet mutually hole in speaker net 1 increase gradually and increase; And hole is outwards to increase round and round; Hole on same ring is uniformly distributed and equal and opposite in direction; Hole on the straight line in the center of circle by speaker net 1 increases from inside to outside gradually.Like this, can make the better effects if of the farther and speaker sound propagation of speaker sound propagation; In addition, return a kind of visual aesthetic feeling of people.
Speaker net 1 as shown in Figure 2, speaker net 1 is still circular, and the center of circle of speaker net 1 is a real point, and the line in the hole from the ray of center of circle real point is parabolic shape; Hole is outwards to increase round and round, and the hole on same ring is uniformly distributed and equal and opposite in direction, and the number in the hole on each ring is identical.Equally, can make the better effects if of the farther and speaker sound propagation of speaker sound propagation; In addition, return a kind of visual aesthetic feeling of people.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
