Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.

It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.

FIG. 1 is a schematic diagram illustrating an assembled state of a detachable projection apparatus according to an exemplary embodiment; fig. 2 is a schematic structural diagram of a detachable projection apparatus according to an exemplary embodiment in a detached state. As shown in fig. 1-2, the detachable projection apparatus 10 may include a projection host 11 and a sound pickup 12, where the projection host 11 is used to implement a projection function during use, such as displaying a projection picture through a lens 110, and the sound pickup 12 is used to implement a sound pickup function during use, such as picking up a voice of a user near a location through a sound pickup hole 120 to transmit to users at other locations, so that users at different locations can communicate with each other remotely.

In an embodiment, the projection host 11 is provided with a groove, so that the sound pickup 12 can be placed in the groove, and the projection host 11 and the sound pickup 12 are matched to assemble the projection apparatus 10. Pickup 12 may be fitted into a recess of projection unit 11, such that when pickup 12 is assembled into the recess, the top surface of pickup 12 is flush with the top surface of projection unit 11, thereby enhancing the integrity of projection apparatus 10. The sound pickup 12 may be separated from the projection host 11 by an electric, mechanical, push-to-eject, manual operation by a user, and the like, which is not limited in this specification. Although the sound pickup 12 can be freely placed in the groove on the projection host 11, in order to improve the bonding strength between the sound pickup 12 and the projection host 11 and avoid accidents such as falling off of the sound pickup 12 when moving, transporting and the like occur, the sound pickup 12 and the projection host 11 can be assembled by means of clamping, magnetic attraction and the like, and this specification does not limit this matter of course.

In some scenarios, sound pickup 12 may be taken out of a groove on projection host 11, and projection host 11 may perform projection operation independently, and sound pickup 12 may perform audio capture operation independently. The projection host 11 may be electrically supported by connecting to an external power source, or the projection host 11 may be built-in with a battery. The sound pickup 12 is supported by the built-in battery under the condition of being separated from the projection host 11; when the pickup 12 is assembled to the projection host 11, the projection host 11 can supply power to the pickup 12.

When the projection host 11 supplies power to the sound pickup 12, there may be various forms. For example, projection host 11 may charge the internal battery of sound pickup 12, while sound pickup 12 is still powered from the internal battery; for another example, the projection host 11 may directly power the sound pickup 12, that is, the sound pickup 12 obtains power support from the projection host 11, and does not obtain power support from the built-in battery; for another example, the projector main body 11 may simultaneously charge the battery built in the sound pickup 12 and directly supply power to the sound pickup 12.

The projection host 11 may supply power to the sound pickup 12 in a wired manner. For example, the projection host 11 may have a built-in charging module, which forms a charging interface on the surface of the projection host 11, and the pickup 12 is provided with a power receiving interface, so that when the pickup 12 is assembled to the projection host 11, the power receiving interface can be docked to the charging interface, so that the charging module can supply power to the pickup 12. For example, the charging interface may be located on the bottom surface or the side wall of the groove on the projection host 11 shown in fig. 2, and the power receiving interface is located on the bottom surface or the side surface of the sound pickup 12, so that when the sound pickup 12 is assembled to the groove on the projection host 11, the power receiving interface and the charging interface are just in butt joint to realize the charging operation.

The projection host 11 may wirelessly supply power to the sound pickup 12. The projection host 11 may have a built-in wireless charging module, and the sound pickup 12 may have a built-in wireless power receiving module, which may be adapted to the wireless charging module for wireless charging. For example, when a charging scheme of electromagnetic induction is adopted, the wireless charging module forms a primary coil, the wireless power receiving module forms a secondary coil, and after the primary coil generates alternating current with a certain frequency, corresponding induced current is generated in the secondary coil through electromagnetic induction, so that wireless charging is realized. For another example, when a magnetic field resonance charging scheme is adopted, the wireless charging module and the wireless power receiving module resonate by adjusting to the same specific frequency, so that the wireless charging module can transmit electric energy to the wireless power receiving module, and wireless charging is realized. In fact, the wireless charging scheme in the related art can be applied to the description for the projection host 11 to wirelessly charge the sound pickup 12.

As can be seen from the above description, the present specification provides the projection apparatus 10 with a separable structure, so that the projection host 11 and the sound pick-up 12 can be separated from each other to achieve related functions, respectively, without affecting each other, and can be assembled into a whole to facilitate storage, transportation, and the like, and especially, the sound pick-up 12 with a small volume is prevented from being lost. Meanwhile, the pickup 12 is charged by the projection host 11, so that the projection host 11 and the pickup 12 can share one set of charging components, and compared with the adoption of a separate projector and pickup equipment, the charging components can be saved.

The user sometimes needs to make adjustment control over the microphone 12; in a teleconference scene, the audio data collected by the sound pickup 12 needs to be transmitted to other meeting places for playing, which relates to network transmission of the audio data. Since the projection host 11 and the sound pickup 12 in this specification together form the projection apparatus 10, the sound pickup 12 does not need to additionally configure functional components for audio processing and network transmission, and only the functional components built in the projection host 11 are directly used, which can avoid waste of hardware resources and computational resources.

For example, in the embodiment shown in fig. 3, projection host 11 may establish a connection with user device 30 via network 20. The projection host 11 and the user device 30 may respectively run a client with a certain application, and the user device 30 may bind its own logged account with the projection device 10 in advance, so that the user device 30 may send a control instruction to the projection host 11 through the network 20. Meanwhile, the projection host 11 may have a built-in first communication module 111, and the sound pickup 12 may have a built-in second communication module 121, where the second communication module 121 is configured to establish a communication connection with the first communication module 111, so that the projection host 11 may send a control instruction to the sound pickup 12 based on the communication connection, thereby controlling the sound pickup 12. Wherein, through adopting first communication module 111 and second communication module 121 that support relevant communication protocol, the communication connection of establishing between first communication module 111 and the second communication module 121 can be for the near field communication connection of any type in the correlation technique, for example bluetooth connection, infrared connection, NFC connection, ZigBee connection, WIFI connection, LoRa connection etc. this description does not restrict this. Keys may also be provided on sound pickup 12, for example, the keys may be touch keys, physical keys or virtual keys on a display screen, so as to implement functions such as power switch, volume adjustment, mute, etc.

In a teleconference scene, the sound pickup 12 may also transmit the acquired audio data to the projection host 11 based on the communication connection established with the projection host 11, and the projection host 11 may perform network transmission with a projection host 40 of another projection device through the network 20 (the hardware structure may be the same as the projection host 11; of course, a different structure may also be adopted), so as to transmit the audio data to the projection host 40, and the projection host 40 performs playing through a built-in speaker or an external speaker.

Take the teleconferencing scenario shown in fig. 4 as an example. When the projection apparatus 10 of the present specification is used, when the participants, user a, user B and user C, sit at the right side of the conference room, the projection host 11 projects the sound onto the curtain 50 at the left side of the conference room, the sound pickup 12 is separated from the projection host 11, and the sound pickup 12 is placed at the right side of the conference room where the users a, B and C are located, so that although the projection host 11 is far away from the participants in order to keep a reasonable distance from the curtain 50, the sound pickup 12 can be taken down to be close to the participants, thereby clearly collecting the conference voices of the participants.

Meanwhile, the projection host 11 needs to dissipate heat through the cooling fan in the operation process, so that the pickup 12 is far away from the projection host 11 by separating the pickup 12 from the projection host 11, the influence of noise and vibration generated by the cooling fan during operation on the audio data acquisition of the pickup 12 can be avoided, and the acquired conference voice is clear and free of noise. Compared with the scheme of integrating the sound pickup 12 into the remote controller, the independent sound pickup 12 is not limited by the internal space of the remote controller, and can provide a relatively larger assembly space, for example, a sound pickup array including a plurality of sound pickup units can be adopted to achieve a better sound pickup effect.

The present description is not intended to be limited to the particular configuration of projection device 10. For example, the projection host 11 may have a rectangular parallelepiped structure such as shown in fig. 5-6, in addition to the cylindrical structure shown in fig. 1-2; for another example, the sound pickup 12 may have a rectangular parallelepiped structure such as that shown in fig. 6, in addition to the discoid structure shown in fig. 1 to 2 and 5.

For the projection apparatus 10 of this specification, in addition to the projection host 11 and the sound pickup 12, the projection host 11 may be matched with other types of data collectors, the projection host 11 may be detachably assembled with any type of data collector, and in an assembled state, the data collector is charged to realize multiplexing of charging components, and a network function and a computing power of the projection host 11 may be multiplexed to realize control of the data collector and transmission of data collected by the data collector.

Taking the projection apparatus 10 shown in fig. 7-8 as an example, the projection apparatus 10 includes a projection host 11 and a camera module 13. As shown in fig. 7, when the camera module 13 is assembled to the host projection unit 11, in an embodiment, the camera module 13 may include a built-in battery, so that the host projection unit 11 can charge the camera module 13, and the charging process may refer to the description of the host projection unit 11 in the above embodiment for charging the sound pickup 12, which is not described herein again. In another embodiment, the camera module 13 may not include a built-in battery, and the camera module 13 may be powered by the projection host 11 regardless of whether the camera module 13 and the projection host 11 are in an assembled state or a separated state, and the power supply form may include a wired form or a wireless form, which is not limited in this specification.

As shown in fig. 8, when the camera module 13 is separated from the projection host 11, the camera module 13 can independently perform an image data collecting operation, which is independent of the projection host 11. The camera module 13 may be separated from the projection host 11 in an electric, mechanical, push-to-pop, manual mode, or the like, which is not limited in this specification. Wherein, the camera module 13 can include the camera 131 and the cloud platform 132, so that the camera 131 can be used for implementing image acquisition, and the cloud platform 132 can stabilize the camera 131 and control the shooting direction of the camera 131.

Similar to the embodiment shown in fig. 3-4, the projection host 11 may establish a connection with the user equipment 30 through the network 20, and control the camera module 13 according to a control instruction sent by the user equipment 30, such as controlling the pan/tilt head 132 to change the shooting direction of the camera 131. Meanwhile, the communication connection is established between the projection host 1 and the camera module 13, so that the projection host 1 can receive image data collected by the camera module 13, send the image data to the projection host 40 through the network 20, and perform projection display through the projection host 40. The camera module 13 may further include a key, for example, the key may be a touch key, a physical key, or a virtual key on a display screen, so as to implement functions such as a power switch, zooming, and infrared light supplement.

Simultaneously, projection host computer 11 need dispel the heat through radiator fan at the operation in-process, through with the module 13 and the 11 separation of projection host computer of making a video recording for module 13 keeps away from projection host computer 11, can avoid radiator fan to cause the influence to the video data collection of the module 13 of making a video recording with vibrations at the noise that the during operation produced, ensures that the meeting video picture of gathering is stable.

Projection device 10 of the present description may contain multiple data collectors at the same time. For example, as shown in fig. 9, the projection device 10 may include both the sound pickup 12 and the camera module 13, so that the projection device 10 may be applied to a teleconference scene supporting audio and video. Wherein, in the meeting process, projection host computer 11 is used for realizing the projection show (like the image data of the personnel of meeting who gathers respectively in each place), and adapter 12 is used for gathering the audio data of personnel of meeting, makes a video recording module 13 and is used for gathering the image data of personnel of meeting, then plays and demonstrates by projection host computer 11 with audio data and image data transmission to other places.

In one embodiment, when the number of the data collectors is multiple, the multiple data collectors may be assembled into a data collection assembly, and the data collection assembly may be detachably assembled to the projection host 11. For example, as shown in fig. 9-10, the pickup 12 and the camera module 13 may be assembled, such as stacking the camera module 13 on top of the pickup 12 to form the data collection assembly 14, and the data collection assembly 14 may be adapted to fit into a recess on the projection host 11, or the pickup 12 and the camera module 13 may each independently perform the relevant data collection operation.

In one embodiment, a plurality of data collectors may be detachably mounted to the projection host 11. For example, the corresponding mounting positions of the sound pickup 12 and the camera module 13 may be set on the projection host 11, respectively, so that the sound pickup 12 and the camera module 13 may be separately and freely detachably mounted with the projection host 11.

Regardless of how it is assembled with the projection host 11, i.e., for both embodiments described above, the following applies: in one arrangement, each data collector may have a separate internal battery. For example, the sound pickup 12 and the camera module 13 may be respectively provided with a built-in battery, so that the two can be separated from each other in the embodiment shown in fig. 10, so as to respectively and independently realize the relevant data acquisition operation. In another scheme, for a plurality of data collectors, a part of the data collectors may not have a built-in battery, and after the part of the data collectors are assembled into a data collecting component, the part of the data collectors are powered by built-in batteries of other data collectors, for example, the sound pickup 12 may have a built-in battery, and the camera module 13 does not have a built-in battery, so that the sound pickup 12 may supply power to the camera module 13, but at this time, the sound pickup 12 may work independently, and the camera module 13 cannot work independently, and the camera module 13 and the sound pickup 12 need to be combined into a data collecting component, which may work independently of the projection host 11.

In the embodiment shown in fig. 11, the projection host 11 may have a rectangular parallelepiped structure, not limited to the cylindrical structure shown in fig. 7-10, similar to the embodiment shown in fig. 5-6. While the sound pickup 12 and the camera module 13 are assembled as the data acquisition assembly 14 in the embodiment shown in fig. 11, a further integration is achieved compared to the above-described embodiment: the pan-tilt 132 of the camera module 13 is located in the housing at the bottom and the top, and includes the sound pickup 12 and the camera 131 of the camera module 13, and the top of the housing is provided with the sound pickup hole 120 of the sound pickup 12. The built-in battery and power assembly of the data acquisition assembly 14 are shared between the pickup 12 and the camera module 13, and the projection host 11 can uniformly supply power to the data acquisition assembly 14. Then, during the use process, the data acquisition assembly 14 can be integrally separated from the projection host 11, and the data acquisition assembly 14 comprehensively implements the operations of audio acquisition and image acquisition.
