Abstract
The invention provides a method for adjusting the output volume of a sounder by using a portable audio controller on the basis that wireless communication signals sent by the sounder with a wireless communication function obviously attenuates as the propagation distance increases. A computer system is controlled by computer program instructions by establishing a function modular architecture to complete the method. The computer program instructions are stored in a computer-readable storage medium. The method receives the wireless communication signals for short-distance propagation sent by the sounder, and adjusts the output volume of the sounder according to the signal intensity of the received wireless communication signals, specifically, the stronger the received wireless communication signals are, the less the output volume of the sounder sending the wireless communication signals is adjusted; the weaker the received wireless communication signals are, the greater the output volume of the sounder sending the wireless communication signals is adjusted. The volume heard by a user can not significantly change as the own location of the user changes.
Description
Technical field
The present invention relates to the control method of portable audio controller to acoustical generator output volume, the method is by setting up functional module construction, by computer program instructions, control computer system and complete, these computer program instructions are stored in computer-readable recording medium.
Background technology
Notoriously, in the situation that acoustical generator (audio amplifier, loudspeaker etc.) output volume is constant, user distance acoustical generator is far away, and the volume of hearing is just less.There is left and right audio amplifier, and modulated be in the situation of left and right volume balance, if subscriber station is placed in the middle between left and right audio amplifier, the ratio of the left and right volume of hearing is exactly normal, if but user is positioned at the position near left voice box, will hear that left voice box volume is larger, right voice box volume is less, affects audibility.
Summary of the invention
The object of the invention is to allow the acoustical generator volume that user hears in different positions reach unanimity, not because change in location affects audibility.
In order to realize this object, need to adopt the acoustical generator that possesses wireless communication function, its wireless communication signal of sending is significantly decay with the increase of propagation distance, on this basis, with portable audio controller, acoustical generator output volume is regulated, control method and principle thereof are as follows:
Receiving step: receive the wireless communication signal of propagating for short distance of being sent by acoustical generator, the significantly decay with the increase of propagation distance of described wireless communication signal system;
Regulating step: according to the signal intensity of received described wireless communication signal, regulate the output volume of acoustical generator, particularly: receive wireless communication signal stronger, mean that user distance is sent the acoustical generator of this wireless communication signal nearer, for the volume that allows user be unlikely to because closely causing hearing apart from this acoustical generator is too large, just the acoustical generator output volume that sends this wireless communication signal is adjusted to less; Receive wireless communication signal more weak, mean that user distance is sent the acoustical generator of this wireless communication signal far away, for the volume that allows user be unlikely to because far causing hearing apart from this acoustical generator is too little, just the acoustical generator output volume that sends this wireless communication signal is adjusted to larger.
Beneficial effect: no matter user distance acoustical generator is far away or near, the volume that user hears all reaches unanimity, can there is not significant change because user self position changes in volume like this that user hears, even if user walks about, shift one's position, he can not feel that significant change appears in volume yet.
Accompanying drawing explanation
Fig. 1 is smart mobile phone schematic diagram placed in the middle between left and right audio amplifier.
Fig. 2 is that smart mobile phone is near the schematic diagram at left voice box place.
Fig. 3 is that smart mobile phone is away from the schematic diagram of left and right audio amplifier.
Embodiment
In the present embodiment, the smart mobile phone T of audio frequency control formula has been installed as portable audio controller, left and right two audio amplifiers as acoustical generator are controlled, the present embodiment also can extend to the situation of more generators.Smart mobile phone T and left and right audio amplifier are all equipped with WIFI communication device, the WIFI signal that left and right audio amplifier sends has specific sign, can allow smart mobile phone T distinguish that this signal is that left voice box L or right voice box R send, and the signal intensity of the left and right audio amplifier WIFI signal that is configured to send equate.
At first, user's hand-held intelligent mobile phone T stands between two parties between left and right audio amplifier, now smart mobile phone T to left voice box L with to right voice box R distance, equate, as Fig. 1, therefore received equates with WIFI signal intensity from right voice box R from left voice box L, so regulating the ratio of left and right audio amplifier output volume is 1:1, ratio and the prior art of the left and right volume that this state bottom left, right voice box output volume and user hear are as good as, and this state is designated as center condition.
Then, user's hand-held intelligent mobile phone T goes to the place near left voice box L, now smart mobile phone T is nearer apart from left voice box L, apart from right voice box, R is far away, as Fig. 2, therefore the received WIFI signal intensity from left voice box L is greater than the WIFI signal from left voice box L, suppose now to receive from a left side, the ratio of the WIFI signal intensity of right voice box is 3:1, regulate left voice box L output volume to be reduced to half under center condition, regulate right voice box R output volume to be increased to 1.5 times under center condition, thereby make a left side, the ratio of right voice box output volume is 0.5:1.5, be 1:3, the volume that under this state, user hears and a left side, the ratio of right volume is with basic identical under center condition.
If user's hand-held intelligent mobile phone T is away from left and right audio amplifier, as shown in Figure 3, the regulating effect of user's expectation has two types.
The first is away from after left and right audio amplifier, left and right audio amplifier all improves output volume, the volume that keeps user to hear is constant, for this reason, smart mobile phone T need be according to the absolute value of the signal intensity of received WIFI signal or with respect to self value, regulate acoustical generator output volume absolute value or with respect to self value.
The second is user just because of need effect that test listens at a distance away from a left side, right voice box, wish left, right voice box does not improve output volume on the whole, but keep left, the ratio of right voice box output volume, for this reason, smart mobile phone T needs only according to received WIFI signal intensity and the relative value of other wireless communication signal comparison, regulate the relative value of acoustical generator output volume and other acoustical generator comparison, suppose that user's hand-held intelligent mobile phone T is away from a left side, after right voice box, arrive left voice box L and equate apart from keeping to right voice box R, what smart mobile phone T received all weakens to some extent but keeps equating with WIFI signal intensity from right voice box from left voice box L, so smart mobile phone T regulates left, the ratio of right voice box output volume remains 1:1, but do not improve a left side, the output volume of right voice box, thereby the volume that allows user obtain uppick diminishes, but left, the constant effect of ratio of right volume.
The method providing herein, all or part of step wherein can be controlled computer system by computer program instructions and complete by setting up functional module construction, and these computer program instructions are stored in computer-readable recording medium.
