Summary of the invention
The technical problems to be solved in the utility model is that existing loudspeaker of electric powered steering type does not possess auto-lock function; When loudspeaker work vibration-generating, in the situation of decelerating through motor than deficiency, loudspeaker have the possibility that is rotated further, and locating effect is not good.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of electronic embedded ceiling loudspeaker comprise audio amplifier and the support body that is used for installing audio amplifier; Described audio amplifier is sector structure, and its back is arcwall face, and audio amplifier is installed on the support body by rotating shaft, fits in audio amplifier interarea and support body surface; But be provided with the transmission mechanism that a transmission audio amplifier rotates around the axis between support body and the audio amplifier, described transmission mechanism comprises motor, is arranged on the worm gear at audio amplifier back, meshes and be connected to the lip-deep worm screw of support body and motor control assembly with worm gear; Described motor control assembly is installed and is connected with motor and controls motor positive and inverse; Described worm screw makes worm gear move around axle under motor-driven.
Because worm and gear itself has the function of self-locking, therefore, adopt worm gear, worm screw to replace original spur gear tooth bar that uses, can not only regulate as required the sensing scope of loudspeaker, can also after having regulated, guarantee the locating effect of loudspeaker, guarantee audio amplifier in use, can not produce skew because of the vibrations of music, improve acoustic stability.
For assurance device can work all the time, also be provided with stopping means, comprise face-flange dish, sensitive switch that spacing preiection, audio amplifier turn up, described spacing preiection is positioned at the audio amplifier back, and near worm gear top, described sensitive switch is positioned at the support body surface, and power turn-on, the disconnection of control motor.
As a kind of improvement project of the present utility model, also be provided with cover cap, described cover cap covers audio amplifier and removably connects with support body.The setting of cover cap can prevent effectively that dust from entering loudspeaker, impact broadcast effect, and cover cap covered the connection line on the loudspeaker, also can play effect attractive in appearance.
As another kind of improvement project of the present utility model, support body is the tower structure of annular, and audio amplifier embeds wherein.
As another kind of improvement project of the present utility model, described motor control assembly adopts relay.When being in normally open behind the relay power, the motor forward, when being in normally off after the relay outage, motor reversal.
The utility model has the advantages that: the sensing scope of loudspeaker can be regulated according to the needs that use, and regulates the good positioning effect after putting in place.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in Fig. 1-5, the utility model comprises audio amplifier 1, the support body 2 that is used for installing audio amplifier 1, the cover cap 6 that covers audio amplifier 1 and removably connect with support body 2, and the sub-10-1 of audio input end and 10-2 are on cover cap.Described audio amplifier 1 is sector structure, and its back is arcwall face, and audio amplifier 1 is installed on the support body 2 by rotating shaft 7, fits in audio amplifier 1 interarea and support body 2 surfaces; But be provided with around the shaft 7 transmission mechanisms that rotate of a transmission audio amplifier between support body 2 and the audio amplifier 1, described transmission mechanism comprises motor 3, is arranged on the worm gear 4 at audio amplifier back, meshes and be connected to support body 2 lip-deep worm screws 5, stopping means and relay 9 with worm gear 4; Described stopping means comprises spacing preiection 8-1 and sensitive switch 8-2, sensitive switch 8-3, the face-flange dish 8-4 that audio amplifier turns up, described spacing preiection 8-1 is positioned at audio amplifier 1 back, and near worm gear 4 tops, described sensitive switch 8-2,8-3 are positioned at support body 1 surface, and power turn-on, the disconnection of control motor 3; The output of described relay 9 is connected with motor 3 and controls motor 3 rotatings, the anodal 9-2 of the DC12V on its input and the cover cap, and the two poles of the earth 8-5 of negative pole 9-3 and motor power AC24V, 8-6 connects; Described worm screw 5 makes worm gear 4 move around axle under motor 3 drives.Described support body 2 is fixed on the ceiling when mounted, the output connecting worm 5 of motor 3, worm screw 5 makes worm gear 4 move around axle under the driving of motor 3, thereby driving audio amplifier 1 rotates around the axis, reach and change the purpose that audio amplifier 1 points to, after adjusting puts in place, worm gear 4, worm screw 5 self-lockings, thus avoided the generation of the displacement phenomenon that causes because of loudspeaker pronunciation vibrations.Because existing worm and gear is all with auto-lock function, therefore, described worm gear 4, worm screw 5 can be adopted the worm and gear of the universal standard.
This device has opens and close two states: open mode: the user is by the control unit input OPEN of peripheral hardware, the DC12v power connection, and make relay 9 connect normally opened contact, motor 3 forwards, and drive worm screw 5 and drive worm gears 4 and make forward and move around axle, when audio amplifier turns to set angle, spacing preiection 8-1 contact and compressive zone roller sensitive switch 8-2, sensitive switch 8-2 makes motor 3 deenergizations, motor 3 stops operating, and by the worm and gear latched position, make audio amplifier navigate to the broadcast angle, generally setting loudspeaker broadcast angle position is 45 degree.Closed state: the user packs up instruction by the control unit input of peripheral hardware, the DC12v power supply disconnects, and make relay 9 connect normally-closed contact, motor 3 counter-rotatings, and drive worm screw 5 makes worm gear 4 do oppositely to move around axle, when the interarea of audio amplifier turns to when being positioned at same plane with support body 2, the sensitive switch 8-3 that is positioned on the support body 2 is pushed by the face-flange dish 8-4 of audio amplifier 1, makes the motor deenergization, and motor 3 stops operating, and by the worm and gear latched position, audio amplifier is closed.
