And horizontally disposed second leaded light section 22, it is reflective that the corner that the first guide-lighting section 21 is connect with the second guide-lighting section 22 is additionally provided with inclination
Face 23；First guide-lighting section 21 is opposite and is positioned apart from the outside of the first reflection wall 11, and the extension end of the second reflection wall 12 is supported
It connects in the lower end of the first guide-lighting section 21, the first reflection wall 11, the second reflection wall 12 and the first guide-lighting section 21 surround a reflector cavity
10, multiple lamp beads 3 are set in reflector cavity 10 and are arranged uniformly around the first reflection wall 11, and the first reflection wall 11 is close to lamp bead 3
Side be evenly equipped with a plurality of triangle reflection prism 13.
As shown in FIG. 6 and 7, the even light-guiding structure of the utility model embodiment, lamp bead 3, which emits beam, is divided into two kinds of light
Line transmission path conducts to the light-emitting surface 25 of the end of the second guide-lighting section 22, and generates two kinds on light-emitting surface 25 and do not share the same light
The superposition of effect；
One of which is that the light direct irradiation that lamp bead 3 issues reflects in the first guide-lighting section 21 of light guide 2,
Light is refracted to inclination reflective surface 23, is then inclined by reflective surface 23 and is reflexed to light-emitting surface 25；As shown in fig. 7, due to multiple
Lamp bead 3 is arranged uniformly around the first reflection wall 11, and the light direct irradiation that multiple lamp beads 3 issue is on light guide 2, most
The light efficiency of light and dark interphase distribution is showed from light-emitting surface 25 eventually.
Another kind is that the light that lamp bead 3 issues is radiated on the first reflection wall 11, and light is by triangle reflection prism 13
It is broken up after diffusing reflection, the light broken up reflexes in the first guide-lighting section 21 through the second reflection wall 12 reflect again, light
It is refracted to inclination reflective surface 23, is then inclined by reflective surface 23 and reflexes to light-emitting surface 25, finally showed on light-emitting surface 25
Uniform bar shaped light efficiency.
Preferably, the section of triangle reflection prism 13 is isosceles triangle, and such light is by triangle reflection prism 13
When diffusing reflection, light can be broken up by relatively uniform, can so guarantee finally show more on light-emitting surface 25
Add uniform bar shaped light efficiency.
More preferably, the bottom edge of the triangular-section of triangle reflection prism 13 and high equal length, and numerical value is 0.3-
0.6mm；So light can be broken up more uniform, more uniform to guarantee finally show on light-emitting surface 25

Side leans；By being clamped the clamping engagement of tenon 61 and clamping groove 24, and under the upper side and upper casing 5 of the second guide-lighting section 22
Side leans, so that sealing is formed by light guide 2 between upper casing 5 and lower casing 6, without extraly EVA being used to steep
Cotton or the mode for putting foamed glue completely cut off the inner cavity of speaker and extraneous sealing, save a large amount of material cost of labor, contract
The short production cycle of speaker.
Preferably, at least one sealing is provided at the position that the downside of upper casing 5 leans with the second guide-lighting section 22
Protrusion 51, the cross sectional shape of seal convexity 51 are triangle, and seal convexity 51 is pressed into second by the way of interference fit and leads
The upper side of light section 22, and then more sealing effect can be obtained.
In conjunction with shown in Fig. 1 and Fig. 5, the utility model embodiment further includes pcb board 4, pcb board 4 be located at reflecting component 1 with it is upper
Between shell 5, multiple lamp beads are set on pcb board 4, to realize purpose that multiple lamp beads 3 are arranged uniformly around the first reflection wall 11.
Identical in order to solve the problems, such as, the utility model additionally provides a kind of speaker, including the uniform of any of the above-described scheme
Light guide structure.
In conclusion the even light-guiding structure of the utility model embodiment, due to being provided with reflecting component 1, and in reflecting component 1
The first reflection wall 11 on be provided with triangle reflection prism 13, lamp bead 3 issue light be radiated on the first reflection wall 11, light
It is broken up after the diffusing reflection of triangle reflection prism 13, the light broken up reflexes to the first leaded light through the second reflection wall 12 again
It is reflected in section 21, light is refracted to inclination reflective surface 23, is then inclined by reflective surface 23 and is reflexed to light-emitting surface 25, finally
Uniform bar shaped light efficiency is showed on light-emitting surface 25.
Further, since lower casing 6 is equipped with clamping tenon 61, the downside of the second guide-lighting section 22 is equipped with and clamping 61 phase of tenon clamping
Clamping groove 24, the downside of the upper side and upper casing 5 of the second guide-lighting section 22 leans；Pass through clamping tenon 61 and clamping groove 24
It is engaged by clamping, and the downside of the upper side and upper casing 5 of the second guide-lighting section 22 leans, so that passing through between upper casing 5 and lower casing 6
Light guide 2 formed sealing, without extraly use EVA foam or point foamed glue by the way of by the inner cavity of speaker with outside
Boundary's sealing isolation, saves a large amount of material cost of labor, shortens the production cycle of speaker.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
