Abstract

The present invention provides a reflective sound box structure that has the advantages of saving space, reducing noise, increasing efficiency, and reducing cost.
One box and one speaker are included, and the box includes one upper and outer sides, one opposing bind upper and lower lower and outer sides, and one upper and outer and lower outer chambers that are combined. The sound chamber has a reflective conduit that extends inwardly from the top and the outside and a sound cup that extends inwardly from the bottom and the outside. The sound cup is provided so as to cover the outer ring side of the reflection conduit, and the sound cup and the reflection conduit are kept at a certain distance. The speaker opens outside and is provided in the box, which produces sound. The design of the sound cup and the reflective conduit and the upper and lower bound lower outer folds quickly join the upper outer and lower outer.

Description

The present invention relates to the structure of a kind of reflective sound box, especially with a design that binds the sound cup and the reflective conduit and the upper and lower folds to save space and noise. It has the advantages of lowering, improving efficiency and reducing costs.

In general, a reflective sound box that is widely used has one box, a resonance film provided in one box and used to generate sound, and a reflection hole on one sound box, Using a reflection hole on the box, when moving the resonance film, the air inside the box is compressed and produced, and the low volume of the bass that is fed out from the back is improved, and the reflection sound box has a good resonance effect. Sound box with Moreover, the advantage of the reflective sound box is that it has an efficiency that is 2 to 3 dB higher than that of the sealed sound box, improving the efficiency of the body, and basically the reflective type clearly has a low frequency volume feeling. Yes.

However, the box size and the size, position, and shape of the reflective sound box described above all affect the low-frequency variables of the system, so controlling the design of the reflective sound box is a common market. More complex and more difficult than the enclosed sound box.

However, the reflection type sound boxes that are widely used only have a reflection hole design, and the effect of resonance is limited. When the reflection hole design is not good, either the overall efficiency of the sound box or the sound It also has a serious impact. For this reason, how to save space, reduce noise, increase efficiency, and reduce the cost of reflective soundboxes has also been expected by vast users.

In view of the shortcomings of the well-known technologies described above, the main purpose of the present invention is to provide a structure of a reflective sound box that saves a kind of space, has low noise, high efficiency, and low cost. There is.

To achieve the above and other purposes, the present invention provides a kind of reflection sound box structure, which includes one box and one speaker. Among them:
The box includes one upper and lower folds, one opposing bound upper and lower folds, and one acoustic chamber that is co-configured from the top and the outer and lower folds. The sound chamber has a reflection conduit that extends inward from one upper and outer sides, and a sound cup that extends inward from the lower and outer sides, and the sound cup is located on the outer ring side of the reflection conduit. The sound cup and the reflective conduit have a certain distance.

The speaker has an open mouth and is installed in a box, which produces sound.
The design of the sound cup, the reflective conduit and the upper and lower rivets binds the upper and lower folds and the lower and outer folds quickly, and saves space, reduces noise and increases efficiency. , And has the advantage of lowering costs.

I am convinced that the technology, means, and effects achieved by the present invention will be understood more deeply and concretely after combining the detailed description of the diagrams with the comparatively excellent embodiments listed here.

See what is shown in FIG. The structure of the reflective sound box of the present invention includes one box 1 and one speaker 2. Among them:
The box 1 is composed of one upper and outer folds 11, one oppositely configured lower and outer folds 12 in contact with the upper and outer folds 11, and one upper and outer folds 11 and 12 The sound chamber 13 is composed, and the upper and outer folds 11 are provided with one perforation 111. The sound chamber 13 has a reflection conduit 131 extending inwardly from the upper and outer sides 11 and a sound cup 132 extending inwardly from the one outer side 12. The cup 132 is provided so as to cover the outer ring side of the reflection conduit 131, and the sound cup 132 and the reflection conduit 131 maintain a certain distance. The speaker 2 is provided in the perforation 111 of the box 1 that opens outward, thereby producing sound.

For the usage status of the above-mentioned components, refer to the places shown in FIGS. Among them, when the speaker 2 emits sound, most of the audio signal is sent from the mouth of the speaker 2 and a small amount of voice pressure remains in the existing box 1 to produce a resonance effect. In addition, the air compression inside the box 1 causes the sound wave to strike the sound cup 132 and produces an effect that the echo resonates in the space of the sound cup 132. In addition, the intensity of the utterance is improved to obtain a relatively excellent sound frequency, and the sound frequency is sent from the bottom flow of the sound cup 132 through the reflection conduit 131 to the other side along the reflection conduit 131. It is emitted radially outward from the open hole, and the audio signal is made leaner.

In addition, in the above-described embodiment, the shapes of the reflection conduit 131 and the sound cup 132 of the sound chamber 13 are U-shaped and W-shaped (FIG. 2), respectively. The double U type and the reflective cup 131 and the sound cup 132 can also be made into the double U type and the multi U type in FIG. 5, and the overall efficiency and tone in the box 1 can be obtained with the multiple reflective conduits 131 and the sound cups 132. You can do better.

In addition, the upper and outer garages 11 are connected through the binding method and the lower and outer galleys 12 (FIG. 1), and the connection with the lock method is not necessary, so that the uttered voice is clear.
