Description
Technical field
The utility model relates to the audio amplifier field, more particularly, relates to a kind of active bass audio amplifier.
Background technology
Usually, when the player carries out tuning to the bass string of a musical instrument, must determine whether the bass string of a musical instrument can produce correct accuracy in pitch according to user's experience and musicality.Yet, if the user is not the professional, or even a beginner, or owing to other certain reasons can't be adjusted according to the musicality of oneself, it is very difficult so the every bass string of a musical instrument being adjusted to suitable accuracy in pitch state.If the accuracy in pitch of electric bass is inaccurate, can make that so the user influences playing effect or music musicality to getting the wrong sow by the ear of bass, destroy it to the learning interest of music.
Based on above-mentioned consideration, the user must buy CALIBRATION bass is carried out tuning, before going out, must be ready to CALIBRATION in advance at every turn, guarantee can not forget, so just allow the user increase burden, especially under more urgent situation, the user is easy to forget this, and general in the market CALIBRATION is all smaller, often takes place to forget the situation that can not find because the user arbitrarily is placed on certain corner.In addition, these CALIBRATIONs use back electric weight meeting approach exhaustion for a long time usually all by the 3v dry cell power supply, do not have in time to note that possible certain sky has caught sight of not electric when needing tuning and can't use, and can bring great inconvenience for it as if the user.
The utility model content
The technical problems to be solved in the utility model is, what overcome that existing CALIBRATION exists easily makes the user leave behind and because of the limited defective of making troubles of its electric weight, provide a kind of active bass audio amplifier with tuner function.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of active bass audio amplifier, comprise input operation module, power module, power amplifier module, power amplifier module comprises first signal processing unit, power amplification unit and the loud speaker that connects successively, the input operation module is connected with first signal processing unit, also comprise the tuner module and select module, the tuner module comprises secondary signal processing unit, microprocessor and the display unit that connects successively, and the input operation module is connected with the secondary signal processing unit; Select module to comprise quiet unit and selector switch, selector switch one end connects quiet unit, and this selector switch other end connects microprocessor, and quiet unit is connected with first signal processing unit; Power module is connected respectively with input operation module, first signal processing unit, power amplification unit, secondary signal processing unit, display unit and selector switch.
In active bass audio amplifier of the present utility model, selector switch is double-point double-throw switch.
In active bass audio amplifier of the present utility model, display unit comprises LED light and LED charactron.
In active bass audio amplifier of the present utility model, display unit comprises the LCD panel.
Implement active bass audio amplifier of the present utility model, compared with the prior art, its beneficial effect is: the utility model directly is integrated into existing CALIBRATION circuit in the active bass audio amplifier, and the bass audio amplifier has the tuner effect concurrently, can not leave behind the situation of CALIBRATION; Selector switch switches freely between tuner module and power amplifier module, and tuner operation and power amplifier operation are independent of each other; The tuner module directly by the power supply power supply, need not to consider quantity problem, for the user has eliminated unnecessary trouble.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the circuit block diagram of the active bass audio amplifier of the utility model.
Embodiment
As shown in Figure 1, the active bass audio amplifier of the utility model, comprise input operation module, power module, power amplifier module, power amplifier module comprises first signal processing unit, power amplification unit and the loud speaker that connects successively, the input operation module is connected with first signal processing unit, also comprise the tuner module and select module, the tuner module comprises secondary signal processing unit, microprocessor and the display unit that connects successively, and the input operation module is connected with the secondary signal processing unit; Select module to comprise quiet unit and selector switch, selector switch one end connects quiet unit, and this selector switch other end connects microprocessor, and quiet unit is connected with first signal processing unit; Power module is connected respectively with input operation module, first signal processing unit, power amplification unit, secondary signal processing unit, display unit and selector switch.Wherein, selector switch is double-point double-throw switch.
The tuning course of work of this active bass audio amplifier is as follows: stir the string of a musical instrument, signal is as importing by the input operation module usually, the opening power module, click the selector switch on LED charactron next door, just enter tuning state (at this moment power amplifier is in mute state, and loud speaker does not have any output) thus.After audio signal enters the tuner module, through filtering, amplify and conversion back formation square wave, square wave is input to microprocessor then, compare with canned data in the microprocessor, determine the signal frequency of input, finally the result is shown by LED charactron and LED light.The LED charactron shows A, B, C, D, E, F and G respectively, and other three LED light show chromatic scale rising tune, chromatic scale falling tone, Heibei provincial opera respectively.
In the above-described embodiments, display unit comprises LED light and LED charactron, and certainly, in other embodiments, display unit can comprise LCD panel or other, all can realize the utility model purpose well.
Above embodiment has been carried out detailed to the utility model, formation is to restriction of the present utility model but these are not.Protection range of the present utility model is not limited with above-mentioned execution mode, as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of putting down in writing in claims.
