Description

A kind of stereo set of novel light guiding structure

Technical field

It the utility model is related to stereo set technical field, and in particular, to a kind of stereo set of novel light guiding structure.

Background technology

The bright spot and cost of product are all that developer most pays close attention to always, it is desirable to obtain gorgeous light bar effect and touch The color lamp effect of induced key, be in the conventional technology need to spend each different lamp bead come it is realizing, it is necessary to pay compared with More costs, and be also to cause great pressure, it is necessary to be divided into for the CPU operation controls on mainboard PCBA components Two groups of algorithms are realized.

Utility model content

The purpose of this utility model is to provide a kind of stereo set of novel light guiding structure, to solve above-mentioned background technology The problem of middle proposition.

To achieve the above object, the utility model provides following technical solution：

A kind of stereo set of novel light guiding structure, including outer cover, main PCB A components, lithium ion battery, front housing, rear shell, Light guide plate, lamp mirror, top plate, lamp control PCBA components, vibrating diaphragm, loudspeaker, side cover, fixing bracket, the loudspeaker, main PCB A components, lithium Ion battery is installed between the front housing and rear shell from front to back, and the outer cover covers in the front housing, rear shell outside, the side Described outer cover one end is placed on, the fixing bracket is arranged on the left side of the front housing and rear shell, fixes the front housing and rear shell On outer cover, the light guide plate is located above the seal cavity that the front housing is formed with rear shell, and the lamp control PCBA components are placed In the top of the light guide plate including lamp control pcb board, the lamp mirror is in the lamp mirror perforate of the outer cover front end, its back side It is in contact with the light guide plate, the top plate is located at the top of the lamp control PCBA components, and the main PCB A components are fixed on institute State in rear shell, powered by lithium ion battery, connected between the lamp control PCBA components and the main PCB A components using electronic cable Connect.Here, the main PCB A components are equipped with CPU, charging interface, audio interface, memory card interface etc., and CPU can be to the lamp Control PCBA components and carry out signal light control；The lamp control PCBA components have lighting function and control sound equipment menu, volume, cut song etc. Touch control function, touch control function can be realized by touch circuit on the lamp control pcb board, the lamp mirror will described in The light that light guide plate receives is reflected by its transparent material attribute, a penetrating luminescent lamp strip is formed, so as to produce Dazzle beautiful effect；Light is transmitted by the lamp control PCBA components, top plate, forms corresponding button lighting effects.

Preferably, vibrating diaphragm, seal box are additionally provided between the front housing and rear shell, the vibrating diaphragm is fixed on by the loudspeaker In the opening of front housing, the seal box is arranged on the inside of the vibrating diaphragm, and the vibrating diaphragm forms the cavity of a sealing with seal box, is used In the bass effect of lifting stereo set.Support bracket fastened mounting means.

Preferably, RGB lamp groups are equipped with the downside of the lamp control pcb board of the lamp control PCBA components, the top plate is using semi-transparent white Material spraying, laser carving have a key symbols, and corresponding perforate is equipped with according to the key symbols on top plate on the lamp control pcb board.When When RGB lamp groups light, uniform Color light is formed in light direct projection to light guide plate；The top is scattered to by the perforate On plate, so as to form multi-colour luminous key symbols effect.Here, RGB lamp bead groups, lamp are designed with the lamp control PCBA components The quantity of pearl is needed depending on the length and size of light guide plate, and the perforate on the lamp control pcb board is through hole, specific location root According to the position of the laser carving symbol on top plate make it is corresponding expand, cause to touch that area is too small to be caused to touch greatly to exempt from gap Liu get Tai The sensitivity of control is inadequate, and the unilateral gap width of the perforate is between 0.2-0.4mm.

Shine since the design of lamp bead will take into account key symbols on top plate, the lamp of the light belt effect both direction of front lamp mirror Light effect, directly can produce obvious luminous point to front irradiation, and the character luminous effect at top is weaker, this is apparently not us The effect wanted.Preferably, the RGB lamps group uses downward setting angle, so that light is aimed downwardly.

Preferably, the light guide plate uses semi-transparent white PC materials, it is outer than described with the contact surface side of the lamp mirror The size of lamp mirror perforate is respectively to long 1-2mm, and internal erosion microgroove, contact surface could allow greatly lamp mirror to be watched all from each angle a bit on cover There is light, do not have the appearance of light dead angle；Material and its characteristic make it have astigmatism, guide-lighting performance, easy to astigmatism, will not cause Light is in point-like.Inside erosion microgroove can play light and spread stepless action.

Preferably, the lamp mirror is using dark brown or PMMA (acrylic) material of dark brown transparent color, so that product It is in black matrix under non-working status, ensures the total tune of appearance.Preferably, the lamp mirror thickness is no more than 3.0mm, width For 1.0-15mm, depending on length is with the length of stereo set.Here, width is too small, and the perforate on aluminium alloy outer cover is difficult, only It can complete to process with the less cutter of diameter, difficulty is larger, and width can influence sound equipment cavity more than 15mm, general portable class It is smaller that stereo set is all particular about size, can load pocket, and easy to go on a journey, overall dimensions are all without being made very big, so lamp mirror Width is suitable, it is impossible to sacrifice tonequality as cost.

Preferably, the top plate is bonded with the lamp control pcb board using the smooth semi-transparent white PC materials in bottom side, is had and dissipated Light, guide-lighting performance, bottom design is smooth, makees touch key-press effect, here, can be two-sided by pasting between top plate and lamp control pcb board The mode of glue is bonded, and conducts touch sensible for zero-clearance.Preferably, the top plate thickness control is too thick between 2.0-2.5mm The Petting Area that can be influenced on plastic cement shaping and touch sensitivity, with lamp control PCBA components will be adjacent to completely, and plastic cement shaping is by noting Molding machine injection forms, and during it, can deform plastic plate in stronger pressure, so the top plate and the lamp control PCBA Two-sided glue material is preferably posted between component as filling gap.

Preferably, the top plate is in addition to the bottom side being bonded with the lamp control pcb board, injector surface, in order to laser carving touch-control Symbol.

Preferably, the bottom side of the outer cover is equipped with non-slip mat, and for placing stereo set when is anti-skidding.

Compared with prior art, the beneficial effects of the utility model are：Novel light guiding structure described in the utility model Stereo set, by optimizing structure setting, especially with structures such as light guide plate, lamp mirror, lamp plates, obtain balance dazzle it is beautiful brand-new Light guide effect, is had the characteristics that reasonable in design, cost very advantageous, low to hardware requirement, can be reached with few cost To gorgeous light bar and colorful character luminous effect.
