Earphone with identification pattern display component

Technical Field

The utility model relates to an electronic component technical field, in particular to earphone with identification pattern show subassembly.

Background

The logo (logo in English) is a mark used by people in life to indicate the characteristics of a certain event. It uses simple, obvious and easily-recognized object image, graph or character symbol as visual language, and has the functions of expressing meaning, emotion and instruction action, etc. besides expressing and replacing what.

The brand mark of electronic equipment generally adopts the form of silk screen printing, metal plating to attach to the surface of product, and is the unchangeable form usually, and shape, gloss, the colour of the sign pattern after the completion can not change promptly, takes earphone product as an example, and in prior art, the sign pattern usually designs in the shell department of earphone, and the show mode of pattern is single, and the homogeneity condition is more serious, finally leads to the product feel and the science and technology of product to feel low, can't form higher appeal to the consumer.

SUMMERY OF THE UTILITY MODEL

For solving prior art, the homogenization that the identification pattern show mode of earphone exists is serious, the quality feels and the science and technology feels low technical problem, the technical scheme of the utility model as follows:

the utility model provides an earphone with a mark pattern display component, which comprises a shell, a mark display piece, a touch pad, a luminous piece and a controller, wherein the mark display piece is used for displaying a mark pattern; the touch pad is used as a control key and used for sending commands to the controller; the luminous piece provides a light source for the identification display piece; the controller is a central processor of the earphone. The utility model discloses specific structure does: the mark display piece comprises a mark pattern, is made of a light-transmitting material and is arranged on the outer side of the shell; the touch panel is used for receiving a touch instruction of a user; the luminous piece is arranged in the shell and corresponds to the position of the identification display piece; the controller is electrically connected with the touch pad and the light-emitting piece respectively; when the touch pad is triggered, the controller drives the luminous piece to emit light and illuminate the identification pattern.

The utility model provides an earphone with identification pattern show subassembly, when the user triggered the touch pad, sent the touch instruction to the controller by the touch pad, the controller received the instruction back drive illuminating part of touch pad and is luminous, then illuminated identification pattern, wherein, can write into light control program in the controller in advance, made light can realize often bright, glimmer, by bright multiple light emitting mode such as dark. Compare traditional, the identification pattern show mode of single unchangeable form, the utility model discloses an identification pattern show mode is more diversified, can promote the article feel and the science and technology sense of electronic product, has more appeal to the consumer.

It should be noted that, the touch panel is the prior art, and before the working principle of the touch panel in this application is understood, the basic working principle of the touch screen needs to be understood first, that is, a capacitance is formed when two electrified conductors approach each other, the formed capacitance is in inverse proportion to the distance between the two electrified conductors, and the area is in proportion to the distance between the two electrified conductors, that is, when the two electrified conductors approach each other gradually, the formed capacitance is gradually increased. When a finger touches the touch screen, a coupling capacitor is formed between a user and the surface of the touch screen due to a human body electric field, and for high-frequency current, the capacitor is a direct conductor and can influence the integral capacitance characteristic of a circuit, so that the circuit of the human body is used for induction work. Therefore, when a finger contacts the touch screen, the capacitance of the touch screen changes, and at this time, the control IC determines whether there is a touch by detecting the change in the capacitance.

In one possible design, the touch pad may be arranged outside the housing, but in order to make the structure of the logo displaying assembly more compact, it is preferable that the touch pad is arranged inside the housing, in particular: the touch pad is attached to the inner side surface of the identification display piece and is provided with a micropore for transmitting light.

The use of a light-diffusing sheet enables the light incident on the logo-displaying sheet to be very uniform.

In one possible design, the controller is a microchip that is disposed on a printed circuit board.

In one possible design, the light emitting member is a plurality of LED lamps uniformly distributed around the controller.

In one possible design, the light-diffusing plate projects toward the circuit board, the projection area covering the luminous element. The design can make full use of the light source, so that the product structure is more compact.

In one possible design, the logo is formed by silk-screen and/or laser process.

The silk-screen printing process is to print ink on the surface of a base material according to the silk-screen printing principle, and then adopts the curing measure of the ink to ensure that the pattern is firm and durable.

The laser process is a process of irradiating a light beam with high energy density to the surface of a substrate to vaporize the material or change the color of the material.

Alternatively, the logo pattern may be processed on the surface or inside of the logo display sheet.

In one possible design, the logo display sheet and the light diffusion plate are made of PC, PMMA, PS or PP.

Wherein, the material selection of the mark display piece and the light diffusion plate is detailed as follows:

PC is polycarbonate, and the light transmittance is about 86%; has high strength and elastic coefficient, high impact strength and wide application temperature range; high transparency and free dyeability; h.d.t. high (heat distortion temperature, which refers to the temperature at which plastic begins to deform when subjected to a certain pressure); the fatigue resistance is good; the weather resistance is good; the product is tasteless and odorless, is harmless to human bodies, and accords with sanitary safety; low molding shrinkage and good dimensional stability.

PMMA is acrylic, and the light transmittance can reach 90 percent; the cost is low, the processing and the forming are easy, and the material is cheap; the silk-screen effect is excellent.

PS is polystyrene, and the light transmittance is 88%; the material has the advantages of good chemical stability, thermal stability, optical transmission property, strong refractivity, strong electrical insulation property and tiny moisture absorption tendency, can be used in a humid environment, and has high radiation resistance.

PP is polypropylene, and the light transmittance can reach 90%; the toughness is excellent; the static electricity is small, and the dust adsorption is less; the surface is not attached with a film, and the production operation is simple.

In one possible design, the micropores are multiple and uniformly distributed in an array; the aperture range of the micropores is 0.08-0.2mm, and the hole center distance range is 0.12-0.2 mm.
