Abstract
The utility model provides a loudspeaker integrating system which comprises a shell body. The shell body contains a loudspeaker main body which comprises an electric conduction input end, the shell body is composed of an upper shell and a lower shell, a PCB board which is electrically connected with the electric conduction input end of the loudspeaker main body is fixed on the lower shell, and a decoupling circuit is arranged on the PCB board. Compared with the prior art, the decoupling circuit is integrated on the loudspeaker integrating system and is near a loudspeaker, which can strengthen the decoupling effect; meanwhile, a space for installing the decoupling circuit on a mobile phone carrier is saved.
Description
[technical field]
The utility model relates to a kind of loud speaker integrated system.
[background technology]
Mini-sound device (as the loud speaker integrated system) is widely used in portable electronic equipments such as mobile phone, notebook computer.Along with fast development, the people of these portable electronic equipments are more and more stronger to its functional requirement, the also corresponding development apace of the loud speaker integrated system that is applied thereon.
Relevant existing loud speaker integrated system comprises housing of being made up of upper casing and lower casing and the loud speaker body that is contained in the housing.Be applied to also be provided with antenna in the loud speaker integrated system in the mobile phone, normally antenna is attached on the surface of loud speaker integrated system housing, because loud speaker has bigger influence to antenna performance, so, the decoupling circuit of eliminating this influence on the mainboard of mobile phone, be provided with usually.Yet decoupling circuit is near more apart from loud speaker, and its effect is good more, and the prior art existence is located at decoupling circuit on the mainboard of mobile phone, is provided with the loud speaker split, and decoupling circuit needs long circuit to link to each other its decoupling poor effect apart from loud speaker.
Thereby, be necessary to study a kind of loud speaker integrated system of strengthening the decoupling effect.
[utility model content]
The technical problem that the utility model need solve is to overcome above deficiency, provides a kind of decoupling effect good loud speaker integrated system.
According to the above-mentioned technical problem that needs solution, designed a kind of loud speaker integrated system, comprise the housing of accommodating the loud speaker body, described loud speaker body comprises the conduction input, described housing is made up of upper casing and lower casing, be fixed with the pcb board that electrically connects with loud speaker body conduction input on the described lower casing, pcb board is provided with decoupling circuit.
Further improve as the utility model, described pcb board links to each other with loud speaker body conduction input.
Further improve as the utility model, described lower casing is provided with the screens of location pcb board.
Compared with prior art, decoupling circuit of the present utility model is integrated on the loud speaker integrated system, and is near with loudspeaker distance, can strengthen the decoupling effect, simultaneously, saved on the mobile phone carrier to the space that decoupling circuit is established is installed.

[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As depicted in figs. 1 and 2, be the utility model loud speaker integrated system, comprise housing 1 and be contained in the interior loud speaker body 2 of housing.The loud speaker body is a mini-sound device, comprises conduction input (for diagram), when to conduction input input audio signal, but sounding.
The housing 1 of present embodiment is made up of upper casing 10 and lower casing 11.As shown in Figure 2, the loud speaker body is contained in the lower casing 11, is provided with screens 110 in a side of lower casing, and screens 110 internal fixation have a pcb board 3.
As shown in Figure 3, the pcb board 3 of present embodiment is provided with output 30, input 31, reaches the decoupling circuit U1 between output and input.Output 30 electrically connects with the conducting end of loud speaker body, input 31 electrically connects with the circuit board of outside mobile phone.The circuit diagram of decoupling circuit U1 comprises the inductance L 1, the L2 that are connected between output and the input as shown in Figure 4, is connected in parallel on capacitor C 1, C2, C3 between output and the input.This circuit U 1 is common decoupling circuit, makes electromagnetic coupled between output and the input reduce or eliminates.Because this decoupling circuit U1 is arranged on the loud speaker integrated system, near apart from the loud speaker body, its decoupling effect is strengthened, and when on the loud speaker integrated system antenna being installed, can reduce the influence of loud speaker body to antenna, improves the performance of antenna.For making the decoupling effect better, promptly decoupling circuit U1 is nearer apart from loud speaker, and saves the trouble of circuit, then the input of pcb board directly can be linked to each other with the conducting terminal of loud speaker body and switch on.
Compared with prior art, decoupling circuit of the present utility model is integrated on the loud speaker integrated system, and is near with loudspeaker distance, can strengthen the decoupling effect, simultaneously, saved on the mobile phone carrier to the space that decoupling circuit is established is installed.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
