Description

A kind of audio amplifier

Technical field

The utility model relates to a kind of audio amplifier, relates in particular to a kind of audio amplifier that can renovate the sound control box that has.

Background technology

In recent years, the portable audio product of advantages of small volume more and more receives an acclaim, and especially receives youthful favor, and becomes a kind of consumption fashion gradually.And the popularizing and raising that the consumer pursues tonequality of various sources of sound such as MP3, MP4, music phone makes the speaker products of the portable multiple source of sound of arranging in pairs or groups again with oneself to have occurred on the market.For example: but portable loudspeaker box has USB linkage function compatible to SD card, supports the interface that enriches of apple products etc.The multi-functional interface that enriches should be provided, accomplish the as far as possible little of audio amplifier volume again, this structural design to audio amplifier is a challenge greatly.

For audio amplifier, especially close case, guarantee air-tightness air tight be important technological problems; Need be coated with fluid sealant at all seam crossings of casing, wiring hole will still be worked as speaker interface more for a long time with cushion or gluing sealing or the like; Especially connection of the circuit of some interfaces and shape and structure are very complicated; Increased the difficulty of sealing, the situation of audio amplifier gas leakage often occurred, serious audio amplifier tonequality.

Summary of the invention

In order to reduce the volume of audio amplifier, make full use of the space, reduce the technology difficulty of audio amplifier sealing simultaneously; The utility model proposes a kind of audio amplifier; Comprise casing, the interface on it and button and a sound control box, said interface and button place on the said sound control box, and are electrically connected with circuit in the casing.Said sound control box comprises protecgulum and bonnet, said bonnet inlay with shown on the casing, the two bottom sides of said protecgulum respectively has through hole, rotates with bonnet through rotating shaft to cooperate.

Especially, said protecgulum has shell fragment near the both sides, top, has salient point at the afterbody of shell fragment, and said bonnet has gathering sill on the position relative with shell fragment, and the two ends of said gathering sill have and the corresponding den of said salient point.Said button or interface place the top of said sound control box protecgulum.

Further, the contact portion at protecgulum and bonnet has vibration proof mechanism.

Further, said interface is USB interface, SD card, AUX input interface, and said button is the control button of music.

Further feature of the utility model and advantage will be set forth in specification subsequently, and, partly from specification, become obvious, perhaps understand through implementing the utility model.The purpose of the utility model can realize through the structure that in the specification of being write, claims and accompanying drawing, is particularly pointed out and obtain with other advantages.

Introduce preferred embodiment below in conjunction with accompanying drawing, the technical scheme that the utility model is proposed specifies.Should be noted that the purpose of accompanying drawing just is convenient to the explanation to the utility model specific embodiment, is not a kind of unnecessary narration or to the restriction of the utility model scope.

Fig. 3 is the structure chart of sound control box.

Fig. 4 is the exploded view of sound control box.

1 casing, 2 sound control boxes, 3 interfaces, 4 buttons, 21 protecgulums, 22 bonnets, 23 shell fragments

24 through holes, 25 dens, 26 gathering sills, 27 rotating shafts, 28 salient points.

Embodiment

As shown in Figure 1, on sound box 1, have a sound control box 2, interface 3 places on the sound control box 2 with button 4, is electrically connected with casing 1 inner circuit, realizes interface function and button operation function.

Like Fig. 3 and shown in Figure 4, sound control box 2 has protecgulum 21 and bonnet 22.Two bottom sides at protecgulum 21 has through hole 24, can cooperate with the bonnet rotation through rotating shaft 27, the sound control box is in opens and closed two states.Bonnet 22 is embedded on the casing 1.

Interface 3 in the utility model is SD card, USB interface, AUX interface etc., and button 4 is the control button of music.When the top of interface 3 or button 4 settings and protecgulum 21; Can realize when sound control box 2 is in opening (as shown in Figure 2); Interface 3 or button 4 expose casing 1, and when sound control box 2 closed conditions (as shown in Figure 1), interface 3 or button 4 are hidden in the inside of casing 1.Both can protect interface or button, effectively utilize the space of audio amplifier again, and reduce the volume of audio amplifier.In the present embodiment, we are located at the top of protecgulum 21 with SD card 31, and when the sound control box was in closed condition, SD was positioned in box house, both can reduce the audio amplifier volume, can prevent losing of SD card again.

Because interface and button are integrated on the sound control box, handling on the bubble-tight technology of audio amplifier, we only need because of the regular shape of sound control box, become simply sealing technology with the sound control box with cushion or gluing sealing, are easier to guarantee that casing is air tight.

Especially; As shown in Figure 4, protecgulum 21 has shell fragment 23 near the both sides, top, has salient point 28 at the afterbody of shell fragment 23; Said bonnet 22 inwalls have gathering sill 26 on the position relative with shell fragment 23, the two ends of said gathering sill 26 have and said salient point 28 corresponding dens 25.Like this, when protecgulum 21 rotations, its operating range is limited to the length of gathering sill 26, and is terminated in 25 places, den.

In addition, in the audio amplifier course of work, the collision that brings for slit and casing 1 vibration that prevents owing to 22 of protecgulum 21 and bonnets can be provided with vibration proof mechanism in the two contact portion.

The above only is the preferred implementation of the utility model; But not to be the limitation of the utility model scope should be understood that for they; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, the some improvement done and retouching also should be regarded as within the protection range of the utility model.
