Abstract

The utility model is a sound box improved speaker, including a box and a speaker, said sound box includes an upper shell, a lower shell to fasten the upper shell, and a sound chamber formed by the upper shell and the lower shell, said sound chamber is a catoptrical canal internally extended from the upper shell, and a sound cup internally extended from the lower shell, said sound cup is covered on the outer ring side of the catoptrical canal, and a certain distance exists between the sound cup and the catoptrical canal; the speaker has a outer hatch and is arranged in the box, being used to make voice, through the design of the sound cup, the catoptrical canal and the fastening between the upper shell and the lower shell, the upper shell and the lower shell can be quickly combined, with advantages of space-saving, small noise, high efficiency and low cost.

Description

Reflective audio amplifier structure-improved

Technical field

The utility model relates to a kind of reflective loudspeaker box structure.

Background technology

Existing reflective audio amplifier, all has a casing, one is installed in casing and the vibrating diaphragm in order to sound, with a reflection hole that is opened on the audio amplifier, and utilize the mode of offering reflection hole casing the higher authorities, when making the vibrating diaphragm motion, the back of the body ripple that the box house air extrusion produces promotes the low amount sense of bass, makes reflective audio amplifier form the audio amplifier with good resonance effect.And the advantage of reflective audio amplifier is the efficient that can exceed 2～3dB than closed audio amplifier, because efficient own improves, reflective basically sounding has apparent in view low frequency amount sense.

But because size, position and the shape of the box sizes of aforesaid reflective audio amplifier and reflection hole all can have influence on the variable of system's low frequency, therefore the design of reflective audio amplifier control is will more being seen closed audio amplifier more complicated, and difficulty is also higher relatively.

Yet, existing reflective audio amplifier all only has the design of reflection hole, therefore the effect of resonance is limited, and when reflection hole designs when bad, for the whole efficiency of audio amplifier and the tone color orientation all have great influence, therefore how to develop a kind ofly save the space, noise is little, efficient is high and the low reflective audio amplifier of cost, is the ardent expectation of numerous users really.

Have in view of that, the utility model designer is based on user's demand, is being engaged in the experience accumulation that this industry designs for many years, and creates a kind of reflective audio amplifier structure-improved, for the industry utilization.

Summary of the invention

Prior art shortcoming in view of the above, main purpose of the present utility model provide and a kind ofly save the space, noise is little, efficient is high and the low reflective audio amplifier structure-improved of cost.

For taking off purpose and other purpose on reaching, the utility model provides a kind of reflective audio amplifier structure-improved, include a casing and loudspeaker, wherein: described casing, include a upper shell, the lower house of one relative clip upper shell, with one be the tone chamber that is defined as jointly by upper shell and lower house, described tone chamber has a reflection conduit that is extended internally by upper shell, with a sound cup that extends internally by lower house, described sound cup is to be located at reflection conduit outer rim side, and the sound cup is to have certain distance with the reflection conduit.

Described loudspeaker, be opening outwards and hold and be placed in the casing, and in order to sound.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be: to rely on sound cup and the design of reflecting conduit and upper shell clip lower house, can be fast in conjunction with upper shell and lower house, and have the space of saving, noise is little, efficient is high and the low advantage of cost.

Embodiment

Relevant for technology, means that the utility model adopted and reach effect, lift preferred embodiment now and cooperate graphic detailed description as after, believe when can by must go deep into and concrete understanding.

Please cooperate and consult shown in Figure 1ly, reflective audio amplifier structure-improved of the present utility model includes a casing 1 and loudspeaker 2, wherein:

Described casing 1 includes the lower house 12 of a upper shell 11, one relative winding upper shells 11, and one is the tone chambers 13 that are defined as jointly by upper shell 11 with lower house 12, and described upper shell 11 is to be equipped with a perforation 111; And tone chamber 13 has a reflection conduit 131 that is extended internally by upper shell 11, and with a sound cup 132 that is extended internally by lower house 12, described sound cup 132 is to be located at reflection conduit 131 outer rim side, and sound cup 132 is to have certain distance with reflection conduit 131; And

Described loudspeaker 2, be opening outwards and hold and be placed in the perforation 111 of casing 1, and in order to sound.

User mode relevant for above-mentioned member sees also Fig. 2 to shown in Figure 3, wherein when loudspeaker 2 send the sound, most of message is sent via loudspeaker 2 peristomes, the small part acoustic pressure then remains in the casing 1 and produces resonance effect, and rely on the air extrusion of casing 1 inside, make sound wave impinge upon sound cup 132, in sound cup 132 spaces, produce the sympathetic response effect of circling round, and can improve intensity of phonation, and obtain a preferable audio frequency, simultaneously described audio frequency, and is held perforate to become radial along reflection conduit 131 from other and is outwards sent, produce simple and honest more full message among reflection conduit 131 via 132 glasss of underflows of sound cup.

In addition, in the foregoing description, the reflection conduit 131 of described tone chamber 13 is slightly to be inverted U and W type (as Fig. 2) respectively with the shape of sound cup 132, certainly reflection conduit 131 also can be set as double-U-shaped as Fig. 4, or reflection conduit 131 also can be set as the double-U-shaped of Fig. 5 and many U type with sound cup 132, and relies on multiple reflection conduit 131 and sound cup 132 can make whole efficiency and tone color orientation in the casing 1 more good.

Moreover upper shell 11 can be connected (as Fig. 1) with lower house 12 by the mode of clip, need not to connect in sealed mode, and therefore the sound that is sent is comparatively pure.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present utility model.
