It should be noted that, in step 110, described output order information is primarily referred to as exporting the instruction of voice messaging in the present invention by the way of non-earphone hands-free, non-.It mainly includes following several situation: pull out when being switched to non-hands-free state by hands-free state, in voice messaging output procedure earphone by non-hands-free way output voice messaging time, when being electrically accessed, detecting when the play mode of mobile terminal is not in being exported by headphone manner and being not in hands-free state, case above all can trigger the output order information generating voice messaging.
It should be noted that, described directional loudspeaker refers to the speaker system utilizing ultrasound wave to have very high directivity in atmosphere, normal audio signals forms the ultrasonic signal containing this audio-frequency information after treatment, and is transmitted in air by directional loudspeaker.Then this ultrasound wave can demodulate original audio signal in atmosphere certainly, forms the acoustical signal with very highly directive that human ear is audible.
It should be noted that, after collecting the output order information of described voice messaging, just need ear's contour images of user is acquired.Then the ear hole of described user is obtained according to ear's contour images of collecting relative to the position of directional loudspeaker and distance.Therefore, the embodiment of the present invention described step 130 particularly as follows:
Described ear contour images is compared with the user ear contour images information prestored, the storage picture corresponding with described ear contour images is obtained in described user ear contour images information, according to described storage picture recorded data, obtain the ear hole of described user relative to the position of directional loudspeaker and distance；Wherein,
The described user ear contour images information prestored includes: directional loudspeaker relative to ear be in diverse location multiple pictures and with the position relative to ear hole of the described directional loudspeaker corresponding to each picture and the data of distance.
Above-described embodiment, in actual applications, if do not find in user ear contour images information with described ear contour images living storage picture, now utilize cy-pres doctrine, looking in user ear contour images information and described ear contour images immediate storage picture, the storage picture that will be closest to is as the corresponding storage picture of described ear contour images.
It should be noted that, obtaining the described directional loudspeaker position relative to ear hole and the data of distance, described directional loudspeaker just can export described voice messaging according to described position and distance orientation.Heretofore described directional loudspeaker Main Basis phasing signal exports described voice messaging.Alternatively, in embodiments of the present invention, a kind of implementation of described step 140 is: according to the ear hole of described user relative to the position of described directional loudspeaker and distance, generate the phasing signal of described voice messaging output, described directional loudspeaker is made to export described voice messaging according to described phasing signal, orientation.
Should be noted that, in above-described embodiment, according to the described directional loudspeaker position relative to ear hole and the data of distance, the technology that the process of the phasing signal being calculated the output of described voice messaging is well known to those skilled in the art, no longer it is described in detail at this.
After the phasing signal obtaining voice messaging output, directional loudspeaker just can carry out the transmission of voice messaging according to this phasing signal, in the ear hole being sent to user orient voice messaging so that user can clearly obtain described voice messaging.
It should be noted that, ear's contour images of described collection may not be sometimes can find in the user ear contour images information prestored.If the undesirable image these collected is also carried out the comparison of image information, the power consumption of mobile terminal can be made to increase.Therefore, in another embodiment of the present invention, described according to described output order information, after the step of the ear's contour images gathering user, described speech-oriented output intent also includes:
