Fig. 1 is the principle framework figure of portable terminal acoustic environment self-adapting adjusting apparatus of the present invention;
Fig. 2 is the process chart of portable terminal acoustic environment self-adapting regulation method of the present invention.
Embodiment
Basic principle of the present invention is: based on the masking effect of psychoacoustic people's ear (when having two kinds of strong and weak alternative sounds, when satisfying certain condition, people's ear sounds that just only there is a kind of sound in sensation) and the auditory properties of people's ear (to the sound in the different frequency scope, the sensitivity difference of people's ear impression) principle, when speech communication, at first open the detection microphone of portable terminal, and the characteristic of the voice signal that picks up of analytical calculation microphone, promptly can know the sound property of surrounding environment, according to psychoacoustic principle, the gain size of corresponding sound passage in the portable terminal is set automatically, to realize the self adaptation adjustment.
Specific embodiment to the inventive method technical scheme is described in further detail below:
In theory diagram shown in Figure 1, comprise the basic channel module 11 of audio frequency of communication terminal, monitoring acoustic environment module 12 and control module 13.In the basic channel module 11 of audio frequency, uplink is arranged: conversation microphone 111 recipients' voice are through analogue amplifier and analog digital converting unit 112 during conversation, handle through speech processing module 113, again through sending through radio-frequency antenna by encoder encodes after digital amplifier 114 processing and amplifying.In the downstream module in the basic channel module 11 of audio frequency, signal decoding after radio-frequency antenna receives from partner, amplify by digital amplifier 115, after speech processing module 113 is handled, convert analog electrical signal to by D/A conversion unit 116 again and amplify driving receiver receiver 117 sounding.The ring signal that has also comprised the prompting function of sending a telegram here in the basic channel module of audio frequency, ring signal amplifies through amplifier 118, drives loud speaker 119 sounding.Comprise monitoring microphone 121 in the monitoring acoustic environment module 12,121 signals that pick up amplify back to ambient sound processing module 122 through monitor signal amplifying unit 123 to be handled, can controlled module 13 needs: the yield value of digital amplifier 114, digital amplifier 115, amplifier 118.Obtain after these yield values the control module 13 unified relevant positions that these values write the basic channel module 11 of audio frequency.Control module 13 also realizes controlling the operating switch of monitoring microphone, the function of controlling the operating switch of conversation microphone simultaneously.
In ambient sound processing module 122, possesses spectrum analysis module, this module can analyze the spectrum component and the intensity of the acoustic environment that monitors, according to this spectrum component and intensity of sound, can compare with the sound mask curve (masking value is along with the change curve of frequency and intensity) of the varying strength that pre-sets and the auditory properties curve of people's ear, by relatively, just can obtain the value that signal gain is adjusted.
In ambient sound processing module 122, analyze the frequency spectrum function A (f) that obtains acoustic environment, be B (p in the sound mask curve distribution that pre-sets
i, f
i), for instance, if masked sound frequency composition is f
i, and the intensity of this sound is p
iThe time, the signal strength signal intensity of sheltering this sound reaches B
iJust can mask off this sound.
In ambient sound processing module 122, set in advance the auditory properties curve distribution T (p of people's ear
j, f
j), for instance, desiring the perceived sounds frequency when people's ear is f
jLoudness reaches p
jThe time, the actual loudness of voice signal will reach T
j
According to B
iAnd T
jValue, the relevant portion gain of the basic channel module of audio frequency just can be set.
In conjunction with Fig. 2, the process step of more detailed description the inventive method.
1, the sensitivity of overall gain and monitoring microphone on each path direction of initialization.
If the overall gain of bell sound path is A1, the up overall gain of audio frequency elementary path is A2, and the overall gain of descending elementary path is A3, and the sensitivity of monitoring microphone is S1.
2, send a telegram here or when calling, 13 modules of terminal obtain interrupting information.
Incoming call or when calling, terminal is sent interrupting information and given 13 modules after 13 modules obtain this information, is opened the control switch of monitoring microphone, and the monitoring microphone is started working.
3, terminal 122 modules are started working, and analyze the needed yield value of each voice pathway.
122 module work according to the sensitivity of monitoring microphone, promptly can obtain the spectral characteristic and the actual intensity of sound of acoustic environment on every side.As previously mentioned, according to the masking effect curve, thereby just know when making the user both sound not too low also not too noisy that come the signal of electric bell sound will reach L1, the lowest gain value that just can obtain bell sound path is A11 for the sound that makes the electric bell sound effectively to mask off environment; For the sound that the receiver place is heard when enough clear, just must make the descending overall gain of audio frequency elementary path reach A31; Enough clear for the sound that the other side is sounded, must make the up overall gain of audio frequency elementary path reach A21;
According to the auditory properties curve distribution of people's ear, can know under the acoustic environment characteristic situation around that will make people's ear sound that sound intensity is enough big, the lowest gain that just must make electric bell sound path is A12 simultaneously; Up overall gain reaches A22; Descending overall gain reaches A32.
In view of the above, just can obtain each passage change amount Δ A that gains accordingly
i(i=1,2,3) are:
ΔA
i＝A
i-max(A
i1，A
i2) i＝1，2，3
4, upgrade the yield value of each passage
The yield value foundation of each passage has just been calculated the Δ A of acquisition
i(i=1,2,3) are upgraded
5, close the monitoring microphone, and open conversation microphone path, allow user's communication.
6, behind the end of conversation, get back to holding state.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
