Abstract
The utility model relates to a tablet personal computer with a plurality of earphone channels. At least two paths of audio output circuits are connected in parallel onto the output end of an audio processing circuit of the tablet personal computer, an earphone interface circuit is correspondingly connected onto each path of audio output circuit, and thus audio output signals of the tablet personal computer can be outputted to a plurality of paths of audio output circuits after processed by the audio processing circuit, the purpose that a plurality of persons enjoy the multi-media at the same time via the corresponding a plurality of earphone interfaces can be achieved, humanization of the tablet personal computer is enhanced, and better experience can be brought to the tablet personal computer user.
Description
Technical field
The utility model relates to a kind of panel computer with plurality of earphone passage.
Background technology
Along with technology is growing, panel computer has become indispensable portable dam in people's daily life, and start gradually to recreational and multimedia aspect development, conventionally when people appreciate multimedia under mobile or outdoor state, in the requirement to audio quality, or prevent from disturbing other people object, can use earphone to export as audio frequency.But on current platform computer, all only has an earphone passage (product such as such as apple iPad, Yuan Dao, the happy Pad of association, Samsung GALAXY Tab P3100, Newman), in the time that two people appreciate multimedia simultaneously, can only everyone with an earplug, so both inconvenience and audibility were also bad, bring better experience cannot to panel computer user, more can not accomplish that many people appreciate multimedia requirement simultaneously.Although and on existing market, have a special plurality of earphone conversion socket, use this socket can reduce output impedance, cause tonequality to decline, even can burn out sound channel circuit.
Utility model content
The purpose of this utility model is to improve a kind of panel computer with plurality of earphone passage, to solve the inconvenience of all only having an earphone passage bring to bring on current panel computer in the time that many people appreciate multimedia.
The utility model provides a kind of panel computer with plurality of earphone passage for solving the problems of the technologies described above, comprise central processing unit, audio frequency processing circuit, audio output circuit and earphone interface circuit, the output terminal of audio frequency processing circuit is connected with the input end of audio output circuit, the output terminal of audio output circuit is connected with earphone interface circuit, the output terminal of described audio frequency processing circuit is at least connected in parallel to two-way audio output circuit, on the output terminal of every road audio output circuit, is connected with respectively the earphone interface circuit of answering in contrast.
Described Mei road audio output circuit all comprises L channel output unit and R channel output unit.
Described earphone interface circuit is arranged on the same side of panel computer, or is arranged on the not homonymy of panel computer.
The beneficial effects of the utility model are: at least two-way audio output circuit is connected in parallel on the output terminal of the utility model by the audio frequency processing circuit at panel computer, on the audio output circuit of every road, correspondence is connected with earphone interface circuit, the audio output signal of panel computer is output on the audio output circuit of multichannel after audio frequency processing circuit is processed like this, reach on corresponding multiple earphone interface simultaneously, realize many people and appreciated multimedia object simultaneously, strengthen the hommization of panel computer, brought better experience to panel computer user.
Accompanying drawing explanation
Fig. 1 is the audio frequency processing circuit figure of the utility model embodiment middle plateform computer;
Fig. 2 is the structural representation of the utility model embodiment middle plateform computer.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
Panel computer comprises central processing unit, audio frequency processing circuit, audio output circuit and earphone interface circuit, audio frequency processing circuit is connected with central processing unit, prior art sound intermediate frequency treatment circuit generally adopts A/D converter, for the digital signal of central processing unit output is converted to simulating signal, the simulating signal obtaining is input on audio output circuit, audio output circuit generally adopts power amplifier, for the simulating signal obtaining is amplified to processing, the output terminal of audio output circuit is connected with earphone interface circuit, earphone interface circuit is traditionally arranged to be earphone jack form.Inventive point of the present utility model is that audio output circuit is at least two-way, is all connected with corresponding with it earphone interface circuit on the output terminal on every road.Audio output circuit in the present embodiment is two-way, as shown in Figure 1, panel computer in the present embodiment comprises central processing unit, audio frequency processing circuit, two-way audio output circuit and two-way earphone interface circuit, central processing unit is connected with audio frequency processing circuit, the output terminal of audio frequency processing circuit is connected with the input end of the second audio output circuit with the first audio output circuit respectively, the output terminal of the first audio output circuit is connected with the input end of the first earphone interface circuit, the output terminal of the second audio output circuit is connected with the input end of the second earphone interface circuit, every road audio output circuit all comprises L channel output unit unit and R channel output unit.The structural representation of panel computer as shown in Figure 2, comprise panel computer body 1, the both sides of panel computer are respectively arranged with earphone jack 2, two earphone jacks 2 here also can be arranged on the homonymy of panel computer, and two earphone jacks are connected with the second earphone interface circuit with the first earphone interface circuit respectively.
According to the actual requirements, the earphone jack on panel computer also can arrange more than two, and convenient more people appreciate multimedia simultaneously, and panel computer of the present utility model hommization more brings better experience to panel computer user.
