Abstract

The utility model relates to a mainboard structure with a biphone interface and comprises a circuit wiring and an audio frequency terminal, of which more than a audio frequency terminals are arranged, and are connected by an flexible circuit board, so that a plurality of earphone terminals for outputting the audio frequency can be arranged, and free of adding other elements, and no modification needs to be done with the original circuit.

Description

Mainboard structure with double earphone interfaces

Technical field

The utility model relates to the mainboard structure of audio amplifier equipment, a kind of mainboard structure with electronic installation of audio frequency output of saying so exactly.

Background technology

Existing have that earphone is generally single earpiece in the audio frequency output electronic installation, from its mainboard PCB, an earphone base is arranged on the mainboard PCB, earphone base is by being fixedly welded on the PCB, the user inserts earphone and realizes in the earphone base listening to function, has only a width of cloth earphone to realize the broadcast of audio frequency by an earphone base in such cases.

And people be routine work, the life in, people's living needs is heard the better stereosonic sound effect of combination, and not only be satisfied with the audio frequency effect of playing by single audio output port, for example MP3, mobile phone, if adopt two audio ports to export, its acoustical quality can be better.

The structure of these electronic installations, the particularly setting of earphone, it is the project organization that depends on its mainboard PCB, earphone is generally single earpiece in the present existing electronic installation, and an earphone base is arranged on the mainboard PCB, listens on a machine simultaneously if realize plural earphone, just a plurality of earphone bases must be arranged, make each earphone that the earphone base of a correspondence be arranged, the position of a plurality of earphone bases must be arranged like this, like this shortcoming of way when motherboard design:

(1) position of a plurality of earphone bases is fixed with respect to mainboard PCB, cannot move the relative position of these earpiece holes when configuration design, makes troubles to configuration design;

Therefore (2) because each earphone base all must have independently space and wires design in the circuit board, a plurality of earphone bases just must have separately independently space and wires design, cause on the wiring board all complexity of space and wires design.

Therefore, be necessary to provide a kind of new simple and direct mainboard structure, so that the audio output port of biphone is set.

The utility model content

Based on this, provide a kind of simple and convenient mainboard structure with double earphone interfaces order of the present utility model, this structure is convenient to be provided with a plurality of audio output ports, to connect a plurality of earphones, for the user provides good audio frequency effect and enjoyment.

Provide a kind of mainboard structure with double earphone interfaces, this structural design simply, does not need to change the circuit design and the wire laying mode of circuit board another order of the present utility model, is convenient to use.

Therefore, the utility model is achieved in that

A kind of mainboard structure with double earphone interfaces, it comprises wiring and audio port, it is characterized in that audio port has more than one, and audio port connects by flexible PCB.By flexible PCB a plurality of audio ports are connected like this, be convenient to be provided with the earphone interface of a plurality of output audios, and need not to increase other parts, original circuit also be need not to improve.

Described mainboard structure with double earphone interfaces, its audio port also is fixed with earphone base, forms earphone interface, so that the grafting earphone carries out audio frequency output.

Described mainboard structure with double earphone interfaces, its audio port are positioned at an end of mainboard, arrange side by side, are convenient to flexible PCB and connect.

Flexible PCB does not need to be welded on the mainboard, can cover original motherboard circuit, does not therefore need original circuit is made improvement, and assembling and application are convenient.

The end of described flexible PCB has a plurality of perforates, and the pin of earphone base interface passes described perforate and welds, and connects with audio output circuit on the mainboard.

Above-mentioned mainboard structure with double earphone interfaces, an one earphone base interface connects an end of flexible PCB, and connects with audio output circuit; The other end of flexible PCB connects one or more earphone base interfaces, can form multichannel voice frequency output, and is user-friendly.

The utility model is by the mode connection PCB and the earphone base of flexible PCB, so just can draw one or more earphone bases by an earphone interface on the mainboard, under the prerequisite that does not change the original design of mainboard, realize the function of one or more earphones, an earphone base interface connects an end of flexible PCB, the other end of flexible PCB connects one or more earphone bases, and earphone base interface is realized the function of a plurality of earphone interfaces from the mainboard.

Because a plurality of earphone bases are to connect in flexible PCB soft arranging wire mode, these earphone interfaces are unfixed with respect to mainboard PCB, can move the position of these earpiece holes with respect to mainboard when configuration design, bring convenience to configuration design.

Because a plurality of earphone bases are connected by an earphone base interface on the mainboard, so the wires design of original ear-phone function need not be changed on the wiring board, brings convenience to line design.

Description of drawings

The structural representation that Fig. 1 implements for the utility model,

Fig. 2 is the structural representation of the utility model flexible PCB,

Fig. 3 is the structural representation that the utility model flexible PCB connects with the earphone base interface.

Embodiment

Below in conjunction with description of drawings enforcement of the present utility model:

Shown in Figure 1, in the mode that the utility model is implemented, the PCB mainboard is provided with two earphone base interfaces 1, earphone base interface 1 is positioned at the both sides, top of PCB mainboard, earphone base interface 1 connects by flexible PCB 2, an earphone base interface 1 connects an end of flexible PCB 2, and connects with audio output circuit; The other end of flexible PCB 2 connects an earphone base interface, can form two-way audio output, and is user-friendly, also provides better audio frequency output effect for the user.

The structure of flexible PCB 2 as shown in Figure 2, its integral body is U type structure, the both sides on U type top are protuberances 21, and protuberance 21 is provided with a plurality of perforates 22, the pin of earphone base interface 1 passes aforesaid perforate 22 and welds (as shown in Figure 3), and connects with audio output circuit on the mainboard.

The voicefrequency circuit of PCB mainboard connects with an earphone base interface like this, can connect with other earphone base interface by flexible PCB, realizes the external output of a plurality of earphone base interfaces, the user is easy to use, and original circuit be need not any change, be convenient to realize, with low cost.

A plurality of earphone bases are to connect in flexible PCB soft arranging wire mode, therefore in design, earphone interface can be unfixed with respect to mainboard PCB, can design the position of these earpiece holes with respect to mainboard as required when configuration design, brings convenience to configuration design.

The above only is an embodiment of the present utility model, can not limit the scope that the utility model is implemented with this, and the execution mode that every structure and utility model purpose and execution mode are similar to all should still belong in the utility model scope of patent protection.
