Abstract

The utility model provides a handy-to-regulate starter for an audio frequency device, which comprises a sound source input selector, a back-stage processing circuit (2), a power amplifier (3), a microprocessor (5), a memory (5) and two or more than two user switch modules (801, 802, 803). Signals are output via the sound source input selector, the back-stage processing circuit and the power amplifier; the user switch modules indicate the microprocessor to take and store corresponding data from the memory in order to control the sound source input selector and the back-stage processing circuit. Different users only need to press a user key, and a needed audio parameter finishes automatic regulation once. Thus, the utility model has the advantages of rapid and convenient use.

Description

The personalized opening device that is used for audio frequency apparatus

The utility model relates to audio frequency apparatus, is specifically related to the opening device of audio frequency apparatus.

Along with the development of Audiotechnica, people are devoted to how to improve acoustics for many years, yet just when stereo set function and performance are constantly improved and improved, people usually are difficult to fast adaptation and also remember these ever-increasing functions.The function of machine is more and more, needs the parameter of adjustment also to reach tens or up to a hundred individual.Common user is often at a loss as to what to do to the adjusting of various buttons on the device panel and knob, other function is known little about it except mains switch and volume adjusting, each user will spend the regular hour, energy goes study to regulate each button, and is very loaded down with trivial details.Moreover different users differs bigger because of the requirement that age, sex cause appreciating, as Karaoke, a man and a woman's sound ray difference, the relevant parameter (frequency compensation, microphone volume, Rev Delay time, the reverberation degree of depth etc.) of machine must be transferred to and be fit to this singer, change a people and reset again once, very trouble.Have, appreciate pattern for difference, as Karaoke, cinema, absolute music, Hi-Fi or the like, each pattern also all has relevant parameters to be configured to reach the best effect of appreciating.According to different appreciation pattern or users, just need different parameter regulation, the inconvenience that brings to domestic consumer and loaded down with trivial details be conspicuous.

Fig. 1 is the primary structure sketch of existing audio frequency apparatus, and signal is by source of sound input selector 1, again through post processing electric circuit 2, power amplifier 3, at last by loud speaker 4 outputs.Mains switch machine button 7 on the stereo set generally has only one at present, regulates parameter configuration after the start usually as required, and these parameters are promptly by microprocessor (CPU) 5 control selector 1 and post processing electric circuits 2.There is memory (E some product inside ²PROM) 6, can remember last operation and part major parameter thereof.

Defective and inconvenience in view of in the above-mentioned stereo set use the utility model proposes a kind of personalized opening device that is used for audio frequency apparatus, need not frequently to regulate parameter during use.

To achieve these goals, a kind of personalized opening device that is used for audio frequency apparatus of the utility model, comprise source of sound input selector, post processing electric circuit, power amplifier, microprocessor, memory, signal is exported behind source of sound input selector, post processing electric circuit, power amplifier, microprocessor control source of sound input selector and post processing electric circuit; The utility model also comprises two or more subscriber switch modules, and subscriber switch module controls microprocessor is got deposit data from memory.

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed description.

Fig. 1 is the basic structure block diagram of existing audio frequency apparatus;

Fig. 2 be the utility model personalized switching device of being used for audio frequency apparatus structure chart.

As Fig. 1, signal is by source of sound input selector 1, again through post processing electric circuit 2, power amplifier 3, at last by loud speaker 4 outputs.Present embodiment is provided with three customer parameter modules 801,802,803, three cover parameters in these three module corresponding stored devices 6, for example module 801 is provided with the parameter of karaoke mode, and module 802 is provided with the parameter of absolute music pattern, and module 803 is provided with the parameter of theater mode.Microprocessor 5 promptly takes out relevant parameter and controls selector 1 and post processing electric circuit 2 from memory, so that stereo set enters corresponding appreciation pattern, reach different effects.

In concrete the application, these three line modules are controlled switching on and off of main power source simultaneously, therefore possesses the effect of mains switch simultaneously, it on device panel the form of three user key-press, promptly allow 3 people that the private subscribers start button of oneself is arranged, name separately can be stored in the memory,, again all parameters of machine be stored in the memory according to separately hobby so that show (prompting) user name during start.Like this, each user has the parameter setting of a cover oneself, as long as one by this key, all parameters are adjusted to the right place by CPU is disposable, comprise: frequency compensation, microphone volume, microphone equilibrium, Active crossover parameter, DSP parameter, Rev Delay time, the reverberation degree of depth etc., and also above all parameters can be upgraded and store at any time.The different users only need click user's key, and the disposable automatic adjustment of its required audio frequency parameter finishes, and uses very convenient, fast.

Claims

1, a kind of personalized opening device that is used for audio frequency apparatus, comprise source of sound input selector (1), post processing electric circuit (2), power amplifier (3), microprocessor (5), memory (6), signal is exported behind source of sound input selector (1), post processing electric circuit (2), power amplifier (3), microprocessor (5) control source of sound input selector (1) and post processing electric circuit (2); It is characterized in that: also comprise two or more subscriber switch modules (801,802,803), subscriber switch module controls microprocessor is got from memory and is deposited user data.

2, opening device as claimed in claim 1 is characterized in that: described subscriber switch module controls main power source is opened and is disconnected.
