Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the drawings.
As shown in fig. 1 to 5, the intelligent projection speaker of the present embodiment realizes dual functions of sound playing and image displaying by providing the projector 20 on the speaker body 10. The sound box body 10 may be designed into a hollow box structure, as shown in fig. 3, so that a required sound cavity can be provided for a loudspeaker, sound effects are ensured, and a containing space can be provided for the projector 20, so that the overall size of the sound box is effectively controlled. In this embodiment, the sound box body 10 is preferably designed into a shell-like structure with a cylindrical lower portion 11 and a hemispherical top portion 12, as shown in fig. 1 and 2, and an opening 13 is formed at a lateral position of the top portion 12 of the sound box body 10 for the projector 20 to enter and exit the sound box body 10.
In order to prevent the projector 20 from being distorted on the projection screen formed on the horizontal desktop and the vertical wall surface, the projector 20 is preferably disposed on the top 12 of the sound box body 10 at an angle of 45 °. Specifically, as shown in fig. 3, the projector 20 is designed to be rotatably installed in the cabinet body 10 about its central axis 21 so as to flexibly adjust the projection direction of the projector 20. The central axis 21 is designed to form an angle of 45 ° with the horizontal line, and the light-emitting surface 22 of the projector 20 (i.e., the light-transmitting surface of the projector 20 projecting light outwards) is parallel to the central axis 21, i.e., the light-emitting surface 22 of the projector 20 also forms an angle of 45 ° with the horizontal line. The projector 20 is designed to rotate about its central axis 21 in 180 ° units, i.e., the angle of each rotation of the projector 20 is 180 °, and during each rotation, the light-emitting surface 22 is switched between the lowest point and the highest point of its rotation, so that the projection surface can be automatically switched between the horizontal plane and the vertical plane. For example, the light emitting surface 22 may be designed to be located at the lowest point of the entire rotation position at the initial position, and in combination with the illustration of fig. 4, the projection direction is inclined downward, so that a projection screen may be formed on the horizontal desktop, and the projection screen is rectangular and will not be distorted. When the projector 20 rotates 180 ° around its central axis 21, the light-emitting surface 22 rotates to the highest point of the whole rotation position, and the projection direction is inclined upwards as shown in fig. 5, so that a projection picture can be formed on a vertical wall surface, and the projection picture is rectangular without correction, so that the problem of trapezoidal distortion of the projection picture does not exist. Therefore, flexible switching of projection pictures between the horizontal desktop and the vertical wall surface is realized, and normal and distortion-free projection pictures can be ensured. The projector 20 is controlled to continue to rotate 180 degrees according to the previous rotation direction or rotate 180 degrees in the opposite direction, so that the light-emitting surface 22 returns to the lowest point, and the projection surface can be switched back to the flat desktop from the vertical wall surface.

When the first motor 30 rotates, the output shaft of the first motor 30 drives the rotating shaft 31 to rotate, and then drives the projector 20 to rotate through the rotating shaft 31, so as to realize automatic switching of the projection surface between the horizontal plane and the vertical plane.
In order to enable the intelligent projection loudspeaker box of the embodiment to push the projector 20 out of the loudspeaker box body 10 when in use, so as to increase the inner cavity volume of the loudspeaker box body, and then leave a large enough sound cavity for a loudspeaker so as to ensure sound effect, the intelligent projection loudspeaker box of the embodiment is also provided with a telescopic mechanism in the loudspeaker box body 10, and the projector 20 is driven to stretch out and draw back relative to the loudspeaker box body 10 by the telescopic mechanism, namely, when the intelligent projection loudspeaker box is started for use, the projector 20 is driven to extend out of the loudspeaker box body 10, and the light-emitting surface 22 is exposed as shown in combination with fig. 2 and 4, so that the projection requirement of the projector 20 can be met, and the sound effect of the loudspeaker box can be improved; when the intelligent projection loudspeaker is shut down and not used, the projector 20 is driven to retract to the loudspeaker body 10, and the loudspeaker is combined with the illustrations of fig. 1 and 3, so that the overall size of the loudspeaker product is reduced, and the loudspeaker is convenient to carry and move. A handle 70 may be further installed on the exterior of the speaker body 10, as shown in fig. 1 and 2, to further facilitate the carrying of the user's hand.

Specifically, the second motor 40 may be fixedly installed in the speaker box body 10, the gear 41 is coaxially installed on the output shaft of the second motor 40, the gear 41 is meshed with the rack 42 to drive, so that the circumferential rotation of the gear 41 is converted into the linear motion of the rack 42, and the projector 20 is driven to linearly move through the rack 42 to extend or retract into the speaker box body 10.
In order to realize reliable pushing of the rack 42 to the projector 20, in this embodiment, the rack 42 is preferably fixedly mounted on a carrying plate 43, and then the carrying plate 42 is fixedly connected to the first motor 30, for example, the carrying plate 42 may be fixedly connected to the first motor 30 by using a screw 44, and the rack 42 is driven to move by the gear 41, so as to drive the carrying plate 43 to move along with the rack 42, and then drive the first motor 30 to perform telescopic motion together with the projector 20 relative to the speaker box body 10.
In order to support the carrying plate 43, the first motor 30 and the projector 20, so that they can be stably assembled in the sound box body 10, a supporting chute (not shown) is fixedly installed in the sound box body 10 in this embodiment, and when the second motor 40 drives the gear 41 to drive the rack 42 to move, the carrying plate 43, the first motor 30 and the projector 20 slide on the supporting chute to control the projector 20 to stably stretch and retract.

The first peripheral side surface 25 is designed to be parallel to the central axis 21, and the light emitting surface 22 is disposed on the first peripheral side surface 25. Designing the second peripheral side surface 26 to form an inward contracted inclined surface relative to the first peripheral side surface 25, when the projector 20 is in an extended state, the top surface 23 and the first peripheral side surface 25 of the housing extend completely out of the sound box body 10, and the second peripheral side surface 26 and the bottom surface 24 are built in the sound box body 10, as shown in fig. 4 and 5; when the projector 20 is in the retracted state, the first peripheral side 25, the second peripheral side 26 and the bottom 24 of the housing are completely built into the speaker box body 10, as shown in fig. 3, and only the top 23 is exposed, and preferably flush with the outer surface of the speaker box body 10, to enhance the overall aesthetic appearance of the speaker box.

The command receiving unit 50 may be a manual switch, a remote control receiving head used in combination with a remote controller, a wireless mobile communication module used in combination with a mobile phone, a network module for linking the internet, or the like. Of course, a plurality of designs can be selected from the above-mentioned forms to be arranged on the sound box body 10, so that a user can conveniently operate the projection sound box in different control forms, and the flexibility of controlling the projection sound box is improved.
The operation instruction received through the instruction receiving portion 50 is transmitted to the control circuit, which may be disposed on a separate PCB board or on flexible circuit boards FPC 61, 62 of the instruction receiving portion 50 connecting the first motor 30 and the second motor 40, which is not particularly limited in this embodiment. The control circuit generates corresponding control signals according to the received operation instructions to control the rotation direction and rotation time (or rotation steps) of the first motor 30 and the second motor 40.
As a preferred circuit configuration design of the control circuit, as shown in fig. 6, the control circuit of this embodiment includes a controller and three linked switches K1, K2, K3. The controller may adopt an integrated chip with data processing capability, such as a single chip microcomputer MCU, and is connected to the instruction receiving portion 50, and analyzes an operation instruction received by the instruction receiving portion 50, so as to generate a corresponding control signal, and control on-off states of the linkage switches K1, K2 and K3.

When the user performs the start-up operation, the controller controls the first linkage switch K1 to be turned on, the second linkage switch K2 and the third linkage switch K3 to be kept in the off state, at this time, the second motor 40 rotates forward, and the driving rack 42 pushes the projector 20 to extend out of the sound box body 10, as shown in fig. 4, the projection direction is a default downward projection, and a projection picture can be formed on the horizontal desktop. If a projection picture is required to be formed on the vertical wall surface, an operation instruction for switching the projection angle can be sent out. At this time, the controller controls the third linkage switch K3 to be turned on, the first linkage switch K1 and the second linkage switch K2 to be kept in an off state, so that the first motor 30 is powered on to operate, and the projector 20 is driven to rotate 180 ° as shown in fig. 5, so that the projection direction is switched to be projected upwards, and a projection picture is formed on the vertical wall surface, thereby realizing flexible switching of two projection surfaces (horizontal surface and vertical surface). When the user performs the shutdown operation, the controller controls the second linkage switch K2 to be turned on, and the first linkage switch K1 and the third linkage switch K3 are kept in an off state, at this time, the second motor 40 is reversed, and the driving rack 42 retracts the projector 20 into the speaker box body 10, as shown in fig. 3, so as to reduce the overall volume of the projection speaker box.
The intelligent projection loudspeaker box of the embodiment has the advantages of small volume, simple structure and convenient use, can realize flexible switching of projection angles, can ensure the quality of projection pictures, and can provide better use experience for users.
