AI Technical Summary
Due to the size limitation of the small speaker, the diameter of the speaker diaphragm is small, resulting in a lack of bass. The separate design of the reflector bass and the active speaker takes up space, affecting the miniaturization effect of the speaker.
A small portable speaker is designed, with a central hole in the middle of the reflector basin, and the speaker is located in the central hole. The reflector basin and the speaker edge are pressed into the shell through a bracket and snap structure to achieve space saving and fixing without glue.
The reflective basin and horn are achieved to overlap height, save height space, make the product thinner, and the use of glue is avoided through the fastening method of snap-on structure, which is more environmentally friendly, more convenient to install, and improve assembly efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to a sound box, in particular to a small portable sound box. Background Art
[0002] At present, reflection basins (also called reflection basins) are used in many speaker designs. Reflection basins are usually similar in appearance to active speaker units, but without voice coils and driving magnets. Reflection basins are usually used to adjust bass and increase the low-frequency effect of the speaker, allowing designers to adjust the overall timbre of the speaker. Especially for some small speakers, due to volume limitations, the speakers used cannot be too large, and generally 2-inch or smaller speakers are used. In this way, since the caliber of the speaker diaphragm is too small, the amount of air pushed each time it vibrates is very small, and the bass volume is directly related to the volume of air pushed by the speaker. Therefore, the inherent defects of small speakers lead to the lack of bass, and reflection basins can better solve this problem. Therefore, reflection basins are widely used in some small sound equipment.
[0003] However, in previous designs, the reflex basin and the active speaker are installed separately in the sound box. Generally, the reflex basin is set above the active speaker, so a large space is required, and a bracket support is required. The bracket occupies a certain product space, so the miniaturization effect of the speaker with this structure is not good enough. Utility Model Content

[0028] Reference Figure 1 , Figure 2The utility model discloses a small portable speaker, including a shell and a bracket 1, a speaker 2 and a reflection basin 3 located in the shell. In order to facilitate manufacturing and assembly, the shell includes a bottom shell 4 and a surface shell 5 buckled with the bottom shell 4, and the buckling method also adopts a method of card hole and card block carding. The bracket 1, the speaker 2 and the reflection basin 3 are all located in the bottom shell 4.
[0029] As shown in the figure, the center hole 6 is provided in the middle of the reflection basin 3. The reflection basin 3 of the present application is similar to a square and matches the shape of the shell. There is a circular center hole 6 in the middle. The circle can match the shape of the speaker 2, because the cross section of the speaker 2 is also circular. The speaker 2 is located in the center hole 6, so that the height of the reflection basin 3 and the speaker 2 overlap. Compared with the previous misalignment design, this saves more space, so that the product is thinner. The basin edge of the reflection basin 3 and the edge of the speaker 2 are pressed into the shell by the bracket 1. The bracket 1 is fixed to the shell by a buckle structure. Such a fastening structure avoids the bonding of glue and is more environmentally friendly. In the present application, the basin edge of the reflection basin 3 and the edge of the speaker 2 are made of rubber material. The buckle structure includes a clamping hole provided on the shell and an elastic clamping plate 7 provided on the bracket 1. The elastic clamping plate 7 is provided with a clamping block 8 that can be clamped into the clamping hole. The above structure is easy to install, does not need to be screwed, and has high efficiency.
[0030] As shown in the figure, the edge 19 of the speaker 2 and the edge of the reflection basin 3 are overlapped with each other, and a convex ring is provided on the bracket 1, which presses the edge 19 of the speaker 2 and the edge of the reflection basin 3 into the shell. Compared with the method of pressing them separately, the overlapping and pressing them into one by the convex ring saves more space and has a compact structure.
[0031] As shown in the figure, the edge 19 of the speaker 2 is provided with a card slot 1, and the edge of the reflecting basin 3 is provided with a convex strip 10 that can be inserted into the card slot 1; the edge of the reflecting basin 3 is provided with a card slot 2, and the bottom surface of the shell is provided with a card plate 11 that can be inserted into the card slot 2. The card slot 1 and the card slot 2 are both annular square grooves, the convex strip 10 is an annular square strip, and the card plate 11 is an annular square thin plate. Through the above structure, the edge 19 of the basin, the edge 19 of the speaker 2 and the card plate 11 are interlocked with each other, which is not only convenient for installation and positioning, but also not easy to slide relative to each other after being pressed, and the structure is more solid. Of course, the edge 19 of the speaker 2 is provided with an annular extrusion surface that contacts the convex ring, and the extrusion surface is a plane, so that the contact is sufficient and the friction is increased.
[0032] As shown in the figure, the basin edge of the reflection basin 3 includes an inner basin edge 12 and an outer basin edge 13, the edge 19 of the speaker 2 is overlapped with the inner basin edge 12, and the inner basin edge 12 and the outer basin edge 13 are both provided with a second card slot, and the second card slot can be clamped with the corresponding card plate 11, and the convex ring includes an inner convex ring 9 and an outer convex ring 14, the inner convex ring 9 presses and fixes the edge 19 and the inner basin edge 12 of the speaker 2 in the shell, and the outer convex ring 14 presses and fixes the outer basin edge 13 in the shell, the above structure can make the reflection basin 3 more firmly fixed and the two concentrically arranged annular card plates 11 can make the reflection basin 3 suspended. Of course, an annular reflection counterweight surface 21 is provided between the inner basin edge 12 and the outer basin edge 13, and the speaker 2 and the reflection counterweight surface 21 are both existing structures, so their specific materials and installation are not described in detail.
[0033] As shown in the figure, it also includes a circuit board 15. The bracket 1 is provided with an elastic hook 16. The circuit board 15 is arranged on the bracket 1 and is restricted by the elastic hook and cannot fall out. The above installation is also very convenient and does not require screws. It also includes a battery 17. The battery 17 is located between the speaker 2 and the face shell 5, and a sponge 18 is provided between the battery 17 and the face shell 5 to prevent the battery from shaking up and down. The face shell 5 is provided with a baffle (not shown in the figure), and the baffle can contact the side of the battery to prevent the battery from shaking left and right. The above installation structure is simple and does not require screws to fix, so the installation efficiency is also high.
[0034] The above is a detailed introduction to a small portable speaker provided by an embodiment of the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of the utility model.
