Description
Technical field
The utility model relates to Bluetooth antenna technical field, particularly relates to a kind of earphone Bluetooth antenna with metal shell.
Background technology
Because the radiofrequency signal distance impact of metal shell on antenna is larger, at present, a good radiofrequency signal distance is had in order to make the Bluetooth antenna of earphone products, general all trying one's best does not adopt metal material to make the shell of Bluetooth antenna, and adopts plastic material to make the shell of Bluetooth antenna completely.But plastic casing is owing to being subject to the restriction of plastic material self attributes, not only appearance texture is poor for the earphone Bluetooth antenna shell that plastic material is made, and make product specification low, and useful life is also shorter.If the coating that will be coated with metal-like on plastic casing can increase cost again.Therefore in order to improve appearance texture and the product specification of earphone Bluetooth antenna, and extend the useful life of earphone Bluetooth antenna, design a kind of with metal shell and metal shell rings little earphone Bluetooth antenna shell to antenna rf shadow signal distance seems very necessary.
Utility model content
The utility model is that shell in order to solve existing earphone Bluetooth antenna only causes earphone Bluetooth antenna shell without metal-like, product specification is low and useful life is short deficiency with plastic casing, provides a kind of with metal shell and metal shell is little on the impact of antenna radio-frequency signal distance, long service life, have metal-like, a kind of earphone Bluetooth antenna with metal shell that product specification is high.
To achieve these goals, the utility model is by the following technical solutions:
A kind of earphone Bluetooth antenna with metal shell, comprise shell, the pcb board of bluetooth driver module and antenna, shell comprises the plastic casing made by ABS plastic material and the metal shell made of metal material, pcb board is fixedly mounted in the cavity of plastic casing and metal shell formation, antenna is fixedly mounted on towards on the pcb board of this side of plastic casing, the power control button of pcb board and the function control button of pcb board are arranged in towards on the pcb board of this side of metal shell, the metal shell of the positive the other side of antenna is provided with metal shell through hole, the function button outer surface of metal shell being respectively equipped with the switch key be connected with power control button and being connected with function control button, switch key and function button all adopt plastic material to make.
This programme earphone Bluetooth antenna shell comprise metal shell and plastic casing, antenna is arranged near plastic end, namely antenna is arranged away from metal shell, and metal shell through hole is set on metal shell, the receiving and transmitting signal of antenna can be freed in and out from metal shell through hole, this addresses the problem the interference effect of antenna radio-frequency signal distance by metal shell.Because the impact of the larger metal shell of metal shell through hole on antenna radio-frequency signal distance is less, antenna is less away from the impact of metal shell metal shell far away on antenna radio-frequency signal distance, therefore, the size of metal shell through hole and the antenna distance from metal shell is set according to the requirement of antenna radio-frequency signal distance.In this programme, the outer end metal shell of earphone Bluetooth antenna shell is made, metal shell adds the metal-like of earphone Bluetooth antenna shell, metal toughness is good, make the earphone Bluetooth antenna class that the life-span is long, metal shell also improves earphone Bluetooth antenna product, also reduce the cost of metallic paint.
As preferably, the outer surface of metal shell is provided with a circular groove, metal shell through hole is arranged in circular groove, and the center in circular groove is provided with the central slide trepanning of floatless switch button, be laid with the edge slip trepanning of four constant function button along the edge of circular groove in circular groove, power control button is arranged on the just right pcb board of central slide trepanning, and function control button is arranged on the just right pcb board of edge slip trepanning.This programme circular groove is convenient to arrange switch key and function button, and switch key is connected on central slide trepanning, function button is connected on edge slip trepanning, the fastness of such assurance function button and switch key and reliability, make this programme reliability high, make earphone Bluetooth antenna long with the life-span.This sound construction degree is good, and can not affect metal shell to antenna radio-frequency signal distance, also improves product specification.
As preferably, the plastic casing groove mated with pcb board is provided with in plastic casing, the metal shell fixed leg being provided with pcb board fixed leg and arranging in triangle disposition in plastic casing groove, pcb board is provided with the breach mated with metal shell fixed leg and the pcb board fixing hole mated with pcb board fixed leg, in the circular groove of metal shell, is provided with the metal shell fixing hole mated with metal shell fixed leg.This structure when mounted, bites the metal shell fixed leg on plastic casing with the breach on pcb board, be then fixed in the plastic casing groove of plastic casing with key screw pcb board; Then namely the metal shell fixing hole on metal shell has been fixed together metal shell and plastic casing with fastened by screw after the metalloid shell fixed leg on plastic casing.This sound construction degree is good, and can not affect metal shell to antenna radio-frequency signal distance, also extends the useful life of earphone Bluetooth antenna and improves product specification.
As preferably, function button is circular, and the outside of function button is the conical surface, and the outer edge of switch key is round shape, and the outer surface of switch key is plane.This structure makes the texture of earphone Bluetooth antenna good, and product specification is high, and sound construction degree is good, also can not affect metal shell to antenna radio-frequency signal distance, also extend the useful life of earphone Bluetooth antenna.
As preferably, earphone base and the USB seat of pcb board are arranged on the pcb board away from antenna.This structure makes the metal in earphone base and USB seat can not have an impact to antenna radio-frequency signal distance, ensures that earphone Bluetooth antenna has good radiofrequency signal distance.
The utility model can reach following effect:
1, the earphone Bluetooth antenna of this patent arranges metal shell through hole on metal shell, and the receiving and transmitting signal of antenna can be freed in and out from metal shell through hole, this addresses the problem the interference effect of antenna radio-frequency signal distance by metal shell.
2, in this patent the outer end metal shell of earphone Bluetooth antenna shell is made, metal shell adds the metal-like of earphone Bluetooth antenna shell, metal toughness is good, make the earphone Bluetooth antenna class that the life-span is long, metal shell also improves earphone Bluetooth antenna product, also reduce the cost of metallic paint.
3, the utility model uses simple, and safety and reliability is high.
