Adjustment unit 125 is coupled to environmental analysis unit 120, in order to judge whether to receive the user ' s preference adjustment signal that user inputs.Control unit 130 is coupled to adjustment unit 125, in order to an output volume of an output sound signal of adjusting device 100.Wherein when adjustment unit 125 does not receive user ' s preference that user inputs and adjusts signal, control unit 130 is controlled signal according to the corresponding volume of environmental analysis unit 120 obtained ambient sound therewith signal, adjusting device 100 output volume.When adjustment unit 125 receives user ' s preference adjustment signal, control unit 130 is adjusted the output volume of signal adjusting device 100 according to user ' s preference.
Broadcast unit 135 is coupled to control unit 130, in order to play output sound signal.Timing unit 145 is coupled to receiving element 105, in order to judge whether a timing time surpasses a Preset Time.Judging unit 150 is coupled to timing unit 145 and broadcast unit 135, in order to judge whether broadcast unit 135 continues to play output sound signal.It should be noted that, environment earthquake at any time due to user place, therefore, when timing unit 145 judgement timing times surpass Preset Time and the lasting broadcasting output sound of judging unit 150 judgement broadcast units 135 signal (user continues call or continues broadcasting audio/video media), judging unit 150 will transmit an enable signal to receiving element 105, make receiving element 105 can again receive sound signal, the external sound situation at continuous updating user place.
Storage element 140 is coupled to respectively signal analytic unit 110, filter unit 115, environmental analysis unit 120 and adjustment unit 125, in order to store message data.Wherein these message data can comprise that resulting at least one signal source, filter unit 115 filter the obtained resulting user ' s preference adjustment signal of inputting with the corresponding volume control signal of ambient sound signal and adjustment unit 125 user that receives of ambient sound signal, 120 calculating of environmental analysis unit behind signal sources to signal analytic unit 115 sound signal of analyzing afterwards.Form 1 is to show the stored message data of storage element 140.
form 1
The example explanation that develops simultaneously as shown in Table 1, a user is received sound signals and after signal analytic unit 110 independent component analysis, is analyzed at least one signal source S by receiving element 105
i.Then, filter element 115 filters out signal source S
irear record ambient sound signal X.Environmental analysis unit 120 utilizes linear regression analysis ambient sound signal X, and calculates a volume output valve Y, and this volume output valve Y is the required set point of user.Finally, then find out Y in the historical message data of storage element 140
maxcarry out the percentage Y of calculation element 100 output volumes
i/ Y
maxdo setting and can complete adjustment demand.Must be noted that the numbers such as above-described a plurality of signals source, be not limited to shown in the content of accompanying drawing of the present invention and specification.
Fig. 2 shows that, according to the method flow Figure 200 according to Environmental adjustments volume described in one embodiment of the invention, the method can be used in a device.First, in step S202, receive a sound signal.In step S204, analyze tut signal and obtain at least one signal source.Then,, in step S206, in tut signal, filter above-mentioned signal source to obtain an ambient sound signal.In step S208, according to message data of above-mentioned ambient sound signal and a storage element, obtain with the corresponding volume of above-mentioned ambient sound signal and control signal.Next, in step S210, judge whether to receive a user ' s preference and adjust signal.If when judgement receives user ' s preference adjustment signal ("Yes" in step S210), in step S212, adjust the output volume of an output sound signal of signal adjusting device according to user ' s preference.If when judgement does not receive user ' s preference adjustment signal ("No" in step S210), in step S214, control the output volume of signal adjusting device according to volume.Then,, in step S216, judge whether a timing time surpasses a Preset Time.If when timing time does not surpass Preset Time ("No" in step S216), get back in step S216, continue timing.When if timing time surpasses Preset Time ("Yes" in step S216), in step S218, judge whether to continue to play output sound signal.If when judgement continues to play output sound signal ("Yes" in step S218), get back to step S202, again receive sound signal.When if output sound signal is not play in judgement ("No" in step S218), play and finish, finish this flow process.
Fig. 3 shows according to the linear regression analysis figure described in one embodiment of the invention, and reference table 1.By utilizing aforesaid independent component analysis method to obtain the analysis of sound signal, and utilize linear regression analysis on statistical method to carry out the output volume of the output sound signal of estimating device.As shown in Figure 3, transverse axis is the ambient sound signal X through removal signal source
i, and the longitudinal axis is calculation element wish adjustment output volume Y
i.If when user inputs user ' s preference adjustment signal according to environment, device will be noted down user ' s preference and adjust output volume Y
ito storage element, add calculating.As shown in Figure 3, figure orbicular spot is the output volume that user adjusts in varying environment sound signal institute wish, and figure cathetus is the operation behavior of utilizing user that linear regression is calculated.Along with user increases device number of operations, the parent number of calculating is also larger, and the result that linear regression analysis is afterwards tried to achieve more approaches this device user's operation behavior.If when user does not input user ' s preference adjustment signal according to environment, install the message data according in ambient sound signal automatic comparison storage element, go to calculate by linear regression analysis and try to achieve corresponding volume output valve Y
i, then according to the maximum (Y that calculates voice output
max) corresponding intrument volume exports corresponding maximum, as output volume equal proportion (Y
i/ Y
max) adjustment.
Therefore, by the apparatus and method according to Environmental adjustments volume of the present invention, can carry out the technology of the automatic regulating apparatus volume along with environment change, by recording user's behavior pattern, come when adjusting standard, prediction meets the output valve that user is desirable, and according to the assessment that adjusts of the training pattern of storage element, person capable of reducing using is when operative installations, and manual overvide volume increases or volume reduces the inconvenience bringing.
Although technology contents of the present invention discloses as above with preferred embodiment; so it is not in order to limit the present invention; those skilled in the art; some changes and the retouching done under the premise of without departing from the spirit of the present invention; all should be covered by category of the present invention, so protection scope of the present invention is to be as the criterion with claim of the present invention.
