By adopting the audio signal processing module, when a user switches by the originally-provided switch, the operating state of the audio signal processing module can be changed, the operation is simple and convenient, and other elements are not required to be additionally matched.
Description
Technical field
The present invention relates to a kind of module of switched circuit, particularly a kind of module of changeable audio output circuit.
Background technology
The so-called data processing equipment of traditional computer only is confined to copy editor, data processing, calculating and simple picture processing etc., but can't fully satisfy popular requirement.Along with computer function more and more stronger, speed is more and more faster, price is more and more lower, computer is healed and is become popular, relative people's requirement is also more and more many.Not only wishing can be while typewriting, listen to the music, sees a film, not having picture also can draw a picture, even has become the main flow of the development of present computer.
Along with science and technology constantly develops, after Windows comes out, multimedia computer becomes the core of industry development, until today, gently, thin, short, under the little designer trends, the computer that can carry becomes modern's demand, in order to adapt to this trend, so computer maker dwindles portable computer (portable computer) again, become the much the same notebook computer of area and notebook, its function and desktop computer are similar, but can put into leather trunk or the handbag of carrying, satisfied the business people everywhere available computers demand.
And in order to increase the operational convenience of user, have loudspeaker and microphone in all in the at present general notebook computer, with two input/output ports (output signal-earphone and input signal-external microphone), when the user will appreciate multimedia file in the notebook computer (as digital videodisc Digital video disc in closely, DVD or videodisc Video Compact is Disc, VCD or the like) or during listoning music, all can carry out the output of audio frequency, also can utilize external earphone output by built-in loudspeaker; Or when the user will import voice data in the notebook computer, then can carry out the input of audio frequency by built-in microphone or external microphone.Display that notebook computer itself possesses and CD-ROM drive, loudspeaker etc. are basic to be equipped with, and cooperates the playing program in the load operation system again, promptly can be used as the terminal equipment of files in different types such as playing image, audio frequency.Yet, understand as the user of familiar with computers operation, utilize aforesaid notebook computer basic equipment, a music CD can be placed on the notebook computer easily to be play, and can be used as sound equipment and uses.
Multimedia science and technology is used in each side at large, for example mobile phone, MP3 (MEPG AudioLayer-3) or the like, become very universal people's livelihood articles for use, the characteristic that exactly because it is frivolous, be convenient for carrying and be subjected to masses and like, but the audio output device of these products is simple and crude, often painstakingly being ignored pursuing short and small exquisiteness just, also is the main cause that general user complained; Because audio output device can't promote, and destroy the quality that audio frequency is exported, relative user also can't obtain real tonequality and enjoy.
Concerning people's ear, sound is a kind of waveform of vibration, and it causes the variable density of atmospheric pressure by vibrate air, via air sound is passed to people's ear, and the people just can hear sound then.With physical angle, sound available pitches (Pitch), volume (Volume), tone color (Tone) are represented, are commonly referred to analog signal.But for only being familiar with 0 and 1 computer, sound has become a series of numeral, must transfer digital signal to analog signal via conversion means after, after loudspeaker output, we just can hear sound.And notebook computer development at present so far, function is almost equally matched with desktop computer, and general notebook computer has added the design of audio amplifier all, its loudspeaker tonequality is fine, can perfectly express audio signal, under this idea, notebook computer no longer is confined to emphasize portable word processor, can also be the portable multimedia center.Yet the external input port (microphone) of notebook computer now also seldom is used, and the function of microphone input often is left in the basket.For technique known, when the user will appreciate the music of MP3, can only appreciate by the earphone output audio signal, if will be when notebook computer be play, then must be by transmission line convert file form, the relative a large amount of memory headroom of the notebook computer that accounts for, and to also bringing quite numerous and diverse formality in user's operation, therefore, this required urgent improved direction of known technology just.
