Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
As shown in Figure 1, the audio play control method of the embodiment of the present invention, is applied to terminal device, the terminal device
Including supersonic signal generator and multiple ultrasonic transducers that different location is arranged in；
The described method includes:
Step 101, in the case where detecting that the audio signal of loudspeaker of the terminal device is to be output, described in triggering
Supersonic signal generator generates multiple ultrasonic electric signals.
In this step, detect loudspeaker audio signal it is to be output in the case where, supersonic signal generator can be triggered
Multiple ultrasonic electric signals are generated, to change the medium on acoustic transmission path based on ultrasonic electric signal generation ultrasonic wave.Its
In, it is that terminal device is known by monitoring the working condition of loudspeaker that loudspeaker needs to export with the presence or absence of audio signal,
And audio signal can be also possible to the audio-video document derived from network derived from the audio-video document of storage local.
Step 102, the multiple ultrasonic electric signal is inputted into the multiple ultrasonic transducer respectively, makes the multiple ultrasound
Energy converter generates ultrasonic wave respectively.
In the embodiment, the position of multiple ultrasonic transducers is preset, so that its ultrasonic wave generated can reach
To desired effect.In this step, step 101 can be triggered to multiple ultrasonic electric signals that supersonic signal generator generates and inputted respectively
Into corresponding ultrasonic transducer, ultrasonic transducer then can generate ultrasonic wave based on the ultrasonic electric signal of input.Wherein,
Ultrasonic electric signal is one-to-one with ultrasonic transducer.
Step 103, it when the multiple ultrasonic transducer generates ultrasonic wave respectively, controls the loudspeaker and exports the sound
Frequency signal.
In this step, terminal device is controlled when ultrasonic transducer generates ultrasonic wave based on the ultrasonic electric signal of input
Loudspeaker output audio signal completes the broadcasting of audio signal.
In this way, terminal device can be directed to the broadcasting of audio by step 101- step 103, pass through triggering ultrasound letter
Number generator generates multiple ultrasonic electric signals, then multiple ultrasonic electric signals are inputted to multiple ultrasounds that different location is arranged in respectively
Energy converter makes multiple ultrasonic transducers generate ultrasonic wave respectively, and when multiple ultrasonic transducers generate ultrasonic wave respectively, it can control
Loudspeaker output audio signal processed.In this way, the air agitation because of ultrasonic wave to ambient enviroment, will cause the atmospheric density in environment
Different degrees of variation occurs, finally make sound after the change in the environment of occur spread speed and sound quality variation, reach
Specific sound result of broadcast.
Moreover, because the audio play control method of the embodiment of the present invention, does not need to carry out audio signal for audio
More parsings, so, audio signal is unlikely to the case where being distorted in excessive resolving, ensure that audio signal
High quality.
Certainly, in this embodiment, it is contemplated that Yao Liyong ultrasonic directional disturbs air (direction is user's ear region),
The ultrasonic transducer of different location generates the ultrasonic wave of each orientation different frequency, forms different acoustic fields.And to pass through different frequency
Ultrasonic wave reaches desired sound effect, then needs for multiple ultrasonic transducers to be arranged in corresponding different location.
Optionally, shield accounting to be promoted, the position of ultrasonic transducer is arranged at the side or the back side of terminal device more, needs
It is configured according to actual spatial distribution.
It should be appreciated that in the embodiment, using the loudspeaker of existing terminal device, except the ultrasound of setting terminal equipment
Outside the position of energy converter, it is also based on the frequency of ultrasonic electric signal, the ultrasonic electric signal of different frequency is inputted accordingly respectively
The ultrasonic transducer of position, control ultrasonic transducer generate the ultrasonic wave of each orientation different frequency.Ultrasonic telecommunications in terminal device
Number the corresponding relationship of target frequency and multiple ultrasonic transducers set, therefore, optionally, in step 101, trigger described super
Sound signal generator generates multiple ultrasonic electric signals, comprising:
