For making the above embodiments of the present application to be better understood, below for mobile phone, describe in detail.
When the size of mobile phone is fixing, for user, between the receiver of mobile phone and the ear of user, between microphone and the face of user, there is not mating to a certain extent dimensionally.In the present embodiment, not mating between ear with receiver, represents with δ 1, and not mating between face with microphone represents with δ 2, and total not mating represents with δ.
User, when using electronic equipment, needs reasonable distribution δ 1 and δ 2, if unreasonable distribution, just likely occurs not hearing the other side and to speak or the other side does not hear the situation of oneself speaking.
In practical application, the profile between the ear and mouth bar of user can regard one section of arc as
(center of circle is O point, and radius is R), as shown in Figure 8.Therefore:
According to formula (1) and (3), can obtain:
In the scene shown in Fig. 8, the head of mobile phone and user is tangent is contacted with a region, and C point is the center of gravity in described region, and in the optional realization of the one of the application, C point position reflects the intention that user distributes δ 1 and δ 2.If the position of C point is positioned at the top of mobile phone, illustrate that user wishes that δ 1 is smaller, the ear (E) of the receiver of mobile phone (E ') and user is closer to some; If the position of C point is positioned at the bottom of mobile phone, illustrate that user wishes that δ 2 is smaller, the face (M) of the microphone of mobile phone (M ') and user is closer to some.
Distributing the intention of δ 1 and δ 2 for describing user qualitatively, doing following hypothesis:
According to formula (4) and (5), can obtain:
Therefore:
With O point be reference axis initial point, OC line direction is X-axis, the vertical direction of OC line sets up coordinate system for Y-axis, then can obtain the position coordinates that E point, E ' point, M point and M ' put:
Position_E＝(-Rcosθ1,Rsinθ1)
Position_E’＝(-R,E’C)
Position_M＝(-Rcos(θ-θ1),-Rsin(θ-θ1))
Position_M’＝(-R,-CM’)
So the distance between the receiver of mobile phone and the ear of user is:
Distance between the microphone of mobile phone and the face of user is:
Can find out, | EE ' | with | MM ' | and be all R, θ, E ' function of M ' and E ' C.What characterize due to R and θ is the contour feature of user's head, and the size of what E ' M ' characterized is mobile phone, these are all constant for specific user, special handset.Therefore, from angle analysis qualitatively, | EE ' | with | MM ' | mainly by the impact of E ' C, and E ' C characterizes is the position of C point on mobile phone screen.E ' C is less, | EE ' | less (receiver of mobile phone and the ear of user are apart from nearer), and | MM ' | larger (distance of the microphone of mobile phone and the face of user is far away); Otherwise E ' C is less, | EE ' | larger (receiver of mobile phone and the ear of user are apart from far away), and | MM ' | less (distance of the microphone of mobile phone and the face of user is nearer).
Therefore, in the embodiment of the application, can according to the position of certain point in contact area, determine the distance situation of change between the microphone of distance situation of change between the receiver of electronic equipment and the ear of described user and/or electronic equipment and the face of described user, and then determine the attitude of electronic equipment relative to the head of user, and dynamically the receiver of electronic equipment or the parameter of microphone are adjusted.
