Abstract
The utility model discloses a mini-type sound box with a telescoping resonance cavity. The mini-type sound box with the telescoping resonance cavity includes a loudspeaker, an upper shell, a middle shell, a lower shell, an audio cable, an audio plug, a circuit board, a loudspeaker net and the telescoping resonance cavity. The loudspeaker net is connected with the upper shell. The loudspeaker net is provided with reinforcing ribs. According to the utility model, the strength of the loudspeaker net is enhanced by arranging the reinforcing ribs on the loudspeaker net, so that the loudspeaker net, especially the central part of the loudspeaker net, is not easy to damage. Besides, the loudspeaker net provided with the reinforcing ribs also can have functions of protecting the sound box and preventing other objects from damaging a resonance film of the loudspeaker. And an effect of protecting the loudspeaker inside is also realized. Noises produced by non-harmonious resonance are eliminated and sound distortion is inhibited in a certain degree.
Description
Technical field
The utility model relates to the miniature loudspeaker box field, in particular, relates 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 the buckle snap ring of inside, 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 damage easily, particularly the middle part; When speaker net contacted with foreign object, the pressure that bear the middle part was maximum, was easy to damage.
The utility model content
Technical problem to be solved in the utility model provides the non-damageable miniature loudspeaker box with flexible resonator of speaker net.
The purpose of this utility model is achieved through the following technical solutions:
A kind of 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 on speaker net.It plays the effect that strengthens speaker net intensity like this.
Preferably, described reinforcement convex is on speaker net.Can play equally the effect that strengthens speaker net intensity.
Preferably, described reinforcement is positioned at the speaker net middle part.Because the pressure maximum is born in the speaker net middle part; In the 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 descends gradually toward the outside.Can strengthen like this intensity of reinforcement.
Preferably, described reinforcement has three angles.Can make like this reinforcement more firm.
Preferably, described three angles increase gradually from the angle to the 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 fully.Easily make, also can be made as other shapes, effect is constant.
Preferably, the contacted side of the another one of described pyrometric cone and speaker net is isosceles triangle.
The utility model is owing to be provided with reinforcement in speaker net, thereby increased the intensity of speaker net, makes it be not easy to damage, particularly the middle part.And, following effect is still arranged, 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.
Description of drawings
Fig. 1 is the schematic diagram of the speaker net of the utility model embodiment.
Wherein: 1, speaker net; 2, reinforcement.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.
Miniature loudspeaker box with flexible resonator of the present utility model 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.
As shown in Figure 1, the height of reinforcement 2 therefrom arrives outward gradually and reduces, and the centre is a point, and reinforcement 2 has three angles, therefrom to outside be exactly three angles on from that point of centre to the limit, three angles increase gradually from the angle to the 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 that equates fully, and so easy manufacturing also can be made as other shapes, and its effect is constant; The another one of pyrometric cone and speaker net 1 contacted side are isosceles triangle.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
