Abstract
The invention discloses a miniature soundbox with a telescopic resonance chamber, which comprises a loudspeaker, an upper casing, a middle casing, a lower casing, an audio cable, an audio plug, a circuit board, a speaker mesh and the telescopic resonance chamber, wherein the speaker mesh is connected with the upper casing, and reinforcing ribs are arranged on the speaker mesh. According to the invention, as the reinforcing ribs are arranged on the speaker mesh, the intensity of the speaker mesh is enhanced, the probability of damage of the speaker mesh, particularly the middle part of the speaker mesh, is low. In addition, the miniature soundbox with the telescopic resonance chamber also has the effects as follows: the speaker can prevent sundries from damaging a loudspeaker resonance film and protect the soundbox; the effect of protecting the inside loudspeaker is also realized; the noise produced by incompatible resonance is 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, and number of patent application is 201210295177.X, and this miniature loudspeaker box comprises loudspeaker, upper casing, mesochite, 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, and audio amplifier mesochite and audio amplifier lower casing are screwed, and tone frequency channel wire is connected with audio jack, circuit board, and flexible resonator is positioned at voice box casing.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, because speaker net is netted, so just easily damage, particularly middle part; When speaker net contacts with foreign object, the pressure that bear middle part is maximum, is easy to damage.
Summary of the invention
Technical problem to be solved by this invention is to provide the non-damageable miniature loudspeaker box with flexible resonator of speaker net.
The object of the invention is to be achieved through the following technical solutions:
A miniature loudspeaker box with flexible resonator, comprises loudspeaker, upper casing, mesochite, lower casing, tone frequency channel wire, audio jack, circuit board, speaker net and flexible resonator, and speaker net is connected with upper casing, and described speaker net is provided with reinforcement.
Preferably, described reinforcement evagination is in speaker net.It plays the effect that strengthens speaker net intensity like this.
Preferably, described reinforcement convex is in speaker net.Can play equally the effect that strengthens speaker net intensity.
Preferably, described reinforcement is positioned at speaker net middle part.Because pressure maximum is born in speaker net middle part; In speaker net middle part, reinforcement is set, can goes better to protect speaker net, in order to avoid speaker net suffers damage.
Preferably, the height of described reinforcement therefrom declines gradually toward outside.Can strengthen the intensity of reinforcement like this.
Preferably, described reinforcement has three angles.Can make like this reinforcement more firm.
Preferably, described three angles increase gradually from angle to middle part width.Like this in order to strengthen the intensity of reinforcement.
Preferably, the corresponding pyrometric cone that is shaped as in described each angle.Play equally humidification, but, also can be made as other shapes, can serve the same role equally.
Preferably, two of described pyrometric cone sides are the right-angled triangles that equate completely.Easily manufacture, also can be made as other shapes, effect is constant.
Preferably, the side that the another one of described pyrometric cone contacts with speaker net is isosceles triangle.
The present invention is owing to being provided with reinforcement in speaker net, thereby increased the intensity of speaker net, makes it be not easy to damage, particularly middle part.And, still there is following effect, 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; 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.
Wherein: 1, speaker net; 2, reinforcement.
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, comprises loudspeaker, upper casing, mesochite, lower casing, tone frequency channel wire, audio jack, circuit board, speaker net and flexible resonator, and speaker net is connected with upper casing, and described speaker net is provided with reinforcement.
Speaker net 1 as shown in Figure 1, speaker net 1 is provided with reinforcement 2, reinforcement can evagination in speaker net 1, also can convex in speaker net 1; Can play same effect: increased the intensity of speaker net 1, made it be not easy to damage.Yet, do not affect like this 1 more original effect of speaker net: speaker net 1 can play the effect of anti-foreign material damage loud speaker resonating membrane, protection audio amplifier; Also work the effect of protecting inner loudspeaker; Eliminate the noise that non-harmonious resonance produces, to a certain degree suppressing audio distortions.Reinforcement 2 is arranged on the middle part of speaker net 1, because, when speaker net 1 contacts with foreign object; the pressure that bear the middle part of speaker net 1 is maximum, just the most easily damages, so; reinforcement 2 is set in the middle part of speaker net 1 and can better goes to protect speaker net 1, make it not fragile.Certainly, it is also passable that reinforcement 2 is arranged on other positions of speaker net 1.
As shown in Figure 1, the height of reinforcement 2 therefrom arrives outward gradually and reduces, and centre is a point, and reinforcement 2 has three angles, therefrom to outside be exactly three angles from that point of centre to limit, three angles increase gradually from angle to middle part width; So just can strengthen the intensity of reinforcement 2.In 2 three angles of reinforcement, the corresponding pyrometric cone that is shaped as in each angle, plays humidification equally, but, also can be made as other shapes, can serve the same role equally.Two sides of pyrometric cone are the right-angled triangles equating completely, and so easy manufacture also can be made as other shapes, and its effect is constant; The side that the another one of pyrometric cone contacts with speaker net 1 is isosceles triangle.
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.
