Please refer to Fig. 3, the electrical block diagram that Fig. 3 is apparatus of the present invention.In order to provide galvanic current source to described device so that the normal operation of described device and be user's use better, in first embodiment of the invention, particularly, described device more comprises an accumulator 17 and a mu balanced circuit 18, described housing 1 inside is located at by described accumulator 17 and two power end is electrically connected with described mu balanced circuit 18 respectively, and described mu balanced circuit 18 is electrically connected with described audio signal generator 11, audio signal sample device 12, audio signal processor 13, storer 14, display 16 and voice generators 15 respectively.
[the second embodiment]
Please refer to Fig. 4, Fig. 4 is the method flow diagram that the present invention finds particular artifact position.Particularly, second embodiment of the invention more provides a kind of method of finding particular artifact position based on vocal print, it is characterized in that, the method comprises the following steps:
Step 1, utilizes audio signal generator to produce and sends sound signal;
Step 2, the bounce-back vocal print after utilizing audio signal sample device to gather described sound signal that described audio signal generator sends to bump from different objects;
Step 3, determines whether to compare out arbitrary described bounce-back vocal print according to described bounce-back vocal print and meets the arbitrary default vocal print of storing in storer;
Step 4, in response to the described bounce-back vocal print meeting, whether the identity information that detects described bounce-back vocal print changes;
Step 5, if nothing demonstrates the default identity information that described bounce-back vocal print is corresponding on display.
Further, before described step 1, also comprise:
Step a, utilizes audio signal generator to produce and sends sound signal;
Step b, the bounce-back vocal print after utilizing audio signal sample device to gather described sound signal that described audio signal generator sends to bump from different objects;
Step c, described bounce-back vocal print is associated with corresponding object and it is stored in described storer in the lump together with corresponding identity information respectively, be defined as default vocal print and default identity information.
Described default identity information comprises mark title, positional information, described in described step 5, on display, demonstrate the default identity information that described bounce-back vocal print is corresponding, particularly will demonstrate described mark title and the described positional information that described bounce-back vocal print is corresponding.
Further, the default vocal print of storing in storer described in described step 3 can be for a plurality of, bounce-back vocal print after described sound signal bumps from different objects also can be for a plurality of, when meeting arbitrary described bounce-back vocal print and meet arbitrary described default vocal print, the described bounce-back vocal print that response is met; Equally, when comparing out a plurality of described bounce-back vocal prints and meet a plurality of described default vocal print, by described a plurality of bounce-back vocal prints that response meets equally, if the identity information of described a plurality of bounce-back vocal prints detected, all do not change, described display will show the default identity information of described a plurality of bounce-back vocal prints successively.
Please refer to Fig. 5, Fig. 5 is vocal print comparison method process flow diagram of the present invention.Particularly, in second embodiment of the invention, described step 3 specifically comprises:
Step 31, detects the waveform vocal print figure of the described bounce-back vocal print that described audio signal sample device gathers;
Step 32, detects the waveform vocal print figure of the described default vocal print of storing in described storer;
Step 32, whether comparison has the waveform vocal print figure of arbitrary described bounce-back vocal print identical with the waveform vocal print figure of arbitrary described default vocal print.
Particularly, the described sound signal of sending due to described audio signal generator is different from the bounce-back vocal print producing after different object collisions, therefore, the vocal print that rebounds described in each takes on a different character, thereby this feature can rely on described waveform vocal print figure to reach identification comparison effect, ought detect the waveform vocal print figure of described bounce-back vocal print identical with the waveform vocal print figure of described default vocal print, represent that described bounce-back vocal print meets described default vocal print.
Please again with reference to figure 4, in described step 4, if when described audio signal processor is detected the identity information of described bounce-back vocal print and changed, perform step 6, again detect the identity information of described bounce-back vocal print and be shown on described display.For example, described camera has moved forward 1 meter, described audio signal processor is by the described identity information of described the second bounce-back vocal print producing after again detecting described sound signal and described camera and bumping and be shown on described display screen, and the positional information of described the second bounce-back vocal print will change.
The present invention can realize following advantage:
By the present invention, when user need to find article, can determine whether to meet by the bounce-back vocal print gathering according to audio signal sample device the arbitrary default vocal print of storing in storer, so that display demonstrates the default identity information that described bounce-back vocal print is corresponding, so, can effectively help user to find article, bring certain facility to user's daily life.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, all should be encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described requirement.
