Embodiment
With reference to the accompanying drawings the embodiment of the invention is elaborated.Structure of the present invention and effect according to description of drawings describe as just an embodiment, and above-mentioned technological thought of the present invention and core constitute and effect is not limited thereto.
For convenience of explanation, inscape identical with existing technologies and same-sign dispense detailed description here.
Fig. 2 and Fig. 3 are the schematic diagrames that the present invention can adjust the A/V equipment of loudspeaker position automatically.
The audio/video devices that the present invention can adjust loudspeaker position automatically is made of following components: audio/video (A/V) equipment (10); Left speaker (30); Right speaker (50) and mobile test section (90).
Here, audio/video devices (10) can be an audio frequency apparatus, also can be video equipment.Video equipment can be a television set; Audio frequency apparatus can be mini assembly, multichannel speaker system etc.
When the stereophonic sound system by left speaker (30) and right speaker (5) constitutes loud speaker, be fixed on A/V equipment (10) inside or be fixed on outside (externally positioned type).
In addition, mobile test section (90) is made of the transducer that the detection user moves.
As mentioned above, usually, when the stereophonic sound system by left speaker (30) and right speaker (50) constitutes loud speaker, when supposing user (listener) (70), can feel best sound effects in the center of A/V equipment (10) anterior locations.At this moment, when the incidence angle of left speaker (30) and right speaker (50) is (60) when spending, can feel best sound effects.
When user (70) moves the position of self, mobile test section (90) detects the user and moves, as shown in Figure 3, move according to detected user, in order to make left speaker (30) and right speaker (50) form the Best Sound incidence angle, rotate left speaker (30) and right speaker (50) to user (70).
Fig. 4 is the formation block diagram that the present invention can adjust the A/V equipment of loudspeaker position automatically.The A/V equipment that the present invention can adjust loudspeaker position automatically is made of following components: control part (11); Mobile test section (90); The 1st loud speaker (30); The 2nd loud speaker (50); The 1st speaker drive portion (110); The 2nd speaker drive portion (130).
Mobile test section (90) is to detect the transducer that the user moves.
In addition, the 1st speaker drive portion (110) and the 2nd speaker drive portion (130) rotate the 1st loud speaker (30) and the 2nd loud speaker (50) respectively.
Control part (11) carries out integral body control to A/V equipment (10), according to the mobile detection information (mobile message and traveling time information) that in mobile test section (11), detects, the angle with front position and present position by the user determines the 1st, the anglec of rotation of the 2nd loud speaker (30,50) is by the 1st, the 2nd speaker drive portion (110,130) rotation of the 1st, the 2 loud speaker (30,50) is controlled.
In other words, when the mobile present position of user (70), mobile test section (90) sends user position information to control part (11).
Relatively the user present position information and the mobile front position information of control part (11) lining in order to ensure obtaining best sound effects, are rotated the 1st, the 2 loud speaker (30,50) by the 1st, the 2 speaker drive portion (110,130).
Fig. 5 is the flow chart of loudspeaker position automatic adjusting method of the present invention.
Below, the flow process of loudspeaker position automatic adjusting method of the present invention is elaborated.If by the initial stage action, the control part (11) of A/V equipment (10) connects power supply, carry out the intrinsic action of A/V equipment.At this moment, control part (11) judges whether to detect user's present position information (S10) from mobile test section (90).
If the judged result in last stage (S10) is to detect the present positional information of user, position according to the user, can enjoy the angle rotary loudspeaker of best sound effects with the user, with user's present position information stores in the temporary storage (not indicating among the figure) of A/V equipment (10) (S30).
Then, judge in the A/V course of action, whether detect the user and move (S50),, compare, judge whether to be in boundary value above (S70) with specific boundary value if judged result is to detect the user to move.Here, so-called boundary value refers to, and the angle that user's traveling time (for example more than 1 second) and move angle can be by should rotary loudspeakers (for example, whether more than move left and right 1 degree of A/V equipment 10) is stipulated.
If judged result (S70) is to be in more than the boundary value, calculate user's move angle (S90).
Then, the anglec of rotation (S110) of loud speaker is calculated in the user's who remembers in angle that moves according to the user and the temporary storage position, for the loud speaker anglec of rotation rotary loudspeaker to calculate, starts drive division (S130).
In the present invention, when the user is a man-hour, loud speaker is adjusted the position automatically; When the user is two man-hours, as shown in Figure 2, the loud speaker about A/V equipment (10) moves by the user who is positioned at A/V equipment (10) center.
