There is no need to attach other components to the book to fix it. Compared with the method of fixing the book by magnetic attraction, the cost of the book can be reduced. At the same time, the clamping structure clamps the book more stably without causing large deviations, thereby avoiding accidental touches and ensuring the accurate correspondence between the audio output content and the touch operation.

[0050] In a preferred embodiment of the present application, Figure 3 , 4As shown, the clamping assembly 40 at least includes a first clamping device 41, and the first clamping device 41 includes:

After one side of the first clamping cover 413 is connected thereto, it can be rotated or folded inward to clamp and fix the lower edge of the bottom page of the book on the first clamping base 411 / first base cover 412.

[0055] In this embodiment, the first clamping cover 413 is a movable part, and its movable end can be combined with the first clamping base through a quick release structure to fix the book. When the book needs to be replaced, the quick release structure can be released. Regarding the first clamping cover 413, on the one hand, it can achieve relative rotation with the base 10 or the first clamping base 411 through a hinge mechanism or a rotating shaft mechanism; on the other hand, the first clamping cover 413 can also be connected to the first clamping base 411 through a flexible material, and then achieve relative folding through the flexibility of the flexible material (such as plastic) itself. Specifically, the first clamping base 411 and the first clamping cover 413 can be integrally formed with a flexible material, or only the connection between the two can be set to a flexible material.

After the book is placed, it can automatically rebound to clamp the book.

[0058] In a preferred embodiment of the present application, Figure 1 , 5 As shown, the clamping assembly 40 further includes a second clamping device 42. The first clamping device 41 and the second clamping device 42 are arranged at two ends of the base 10 opposite to each other to clamp the book. The second clamping device 42 includes:

[0059] A second clamping base is arranged on the base, and a second base cover and a second clamping cover are arranged in sequence above the second clamping base; wherein one side of the second clamping cover is connected to the outer side of the second clamping base through a rotating structure or through a flexible material that can realize a folding action; the second clamping cover and the second base cover are connected through a quick-release structure to realize the clamping or replacement of books.

[0060] In this embodiment, the second clamping device 42 is disposed on the edge of the other end of the base 10 opposite to the first clamping device 41. The second clamping base 421 is fixedly connected to the base 10, and extends to both sides along the upper edge of the base 10 to adapt to the width of the upper edge of the book bottom page.

[0061] In this embodiment, with the center of the base 10 being the inner side, the outer side of the second clamping base 421 refers to the side away from the center of the base 10. After one side of the second clamping cover 423 is connected thereto, it can be rotated or folded inward to clamp and fix the upper edge of the bottom page of the book on the second clamping base 421 / second base cover 422.

[0062] In this embodiment, the second clamping cover 423 is a movable part, and its movable end can be combined with the second clamping base 421 through a quick release structure to fix the book. When the book needs to be replaced, the quick release structure and the quick release structure in the first clamping device 41 can be unlocked.

[0063] Regarding the second clamping cover 423, on the one hand, it can achieve relative rotation with the base 10 or the second clamping base 421 through a hinge mechanism or a rotating shaft mechanism; on the other hand, the second clamping cover 423 can also be connected to the second clamping base 421 through a flexible material, and then achieve relative folding through the flexibility of the flexible material (such as plastic) itself. Specifically, the second clamping base 421 and the second clamping cover 423 can be integrally formed with a flexible material, or only the connecting portion between the two can be set to a flexible material.

[0064] In this embodiment, the quick release structure between the second clamping cover 423 and the second clamping base 421 may be a snap-fit ​​structure, a magnetic structure, or other structures that can achieve quick release, such as Velcro.

[0065] In one embodiment of the present application, Figures 3 to 8 As shown, a plurality of first positioning protrusions 414 are provided on the upper side of the first base cover 412, and the first clamping cover 413 is provided with first positioning holes 415 matched with the first positioning protrusions 414;

[0066] A plurality of second positioning protrusions 424 are disposed on the upper side of the second base cover 422 , and a second positioning hole 425 matching with the second positioning protrusions 424 is disposed on the second clamping cover 423 .

[0067] In this embodiment, the first positioning protrusion 414 and the second positioning protrusion 424 can be set to be cylindrical, but are not limited thereto; the first positioning hole 415 and the second positioning hole 425 can be set to be through holes or blind holes, without specific limitation.

[0068] In this embodiment, the upper end of the touch circuit board 31 is covered on the second base cover 422, and the lower end thereof is covered on the first base cover 412; the touch circuit board 31 is provided with a touch circuit board positioning hole matching the first positioning protrusion 414 and the second positioning protrusion 424;

[0069] A supporting layer 50 is provided between the touch circuit board 31 and the base body 10;

[0070] An inner cover layer 60 is provided above the circuit board for covering the structure below and combining with the base 10. The inner cover layer 60 is provided with holes corresponding to the first positioning protrusion 414 and the second positioning protrusion 424, as well as a plurality of functional holes. The upper part of the inner cover layer 60 is used for placing the book 20, and the bottom cover of the book 20 is provided with book positioning holes corresponding to the first positioning protrusion 414 and the second positioning protrusion 424.

[0071] In this embodiment, two ends of the touch circuit board 31 are respectively arranged on the first base cover 412 and the second base cover 422 , and there is a gap between them and the base 10 . Therefore, the supporting layer 50 can support the touch circuit board 31 .

[0072] In this embodiment, the inner cover layer 60 is mainly used to cover the structure below, such as the touch circuit board, the first clamping base, the second clamping base, the supporting layer, etc. On the one hand, the structure below can be covered to improve the aesthetics of the product, and on the other hand, the material of the inner cover layer 60 is generally a flexible material, and its periphery can also be adhered to the base 10, that is, combined with the base, to play a role in fixing the structure below. In addition, the inner cover layer 60 is also provided with holes corresponding to the first positioning protrusion 414 and the second positioning protrusion 424 for their passage, and a number of functional holes are also provided, such as holes corresponding to USB holes, detection through holes, switch holes, etc.

[0073] In this embodiment, the first positioning protrusion 414 and the second positioning protrusion 424 cooperate with the positioning hole of the touch circuit board, the corresponding hole position of the inner cover layer 60, and the book positioning hole on the lower cover page of the book from bottom to top, that is, the positioning of the touch circuit board, the inner cover layer, and the book can be achieved simultaneously through a set of positioning devices, and the positioning method is very clever. In addition, the bottom cover page of the book 20 is the last cover page, and the book is positioned through the book positioning hole on the bottom cover page. Compared with the sound book fixed by magnetic suction, etc., in the sound book device of the present application, the book and the touch circuit board share a set of positioning protrusion structures, and it is not easy to cause displacement between the book and the sound book device, which can achieve a higher precision book positioning effect.

[0074] In one embodiment of the present application, Figure 8 , 9 As shown, a book recognition module 33 is disposed on the main circuit board 32 , and a plurality of detection through holes 416 opposite to the book recognition module 33 are disposed on the first base cover 412 , so that the book recognition module 33 can detect the book code on the book through the detection through holes 416 .

[0075] In this embodiment, a book code is set on the back of the bottom cover of the book, and the book code is used to uniquely identify the book. The book identification module 33 can identify the book code, and then confirm the identity of the target book through the processor on the main circuit board 32, so as to match the corresponding information processing logic and audio data for the target book, and realize the corresponding audio output. Therefore, the high-precision positioning method provided in the above embodiment can better ensure that the book code can be aligned with the detection through hole 416 and the book identification module 33.

[0076] As an example, the book recognition module 33 can be a photoelectric / image recognition module, and the corresponding book code can be text, symbols, images or any other information that can be recognized by the photoelectric / image recognition module; the book recognition module 33 can also be a radio frequency identification module, and the corresponding book code can be implemented using an electronic tag or a radio frequency card, etc.; the above is only an example, and other methods that can realize book code recognition can be used in this embodiment.

[0077] In one embodiment of the present application, Figure 7 As shown, the touch circuit board 31 is located on one side of the first clamping base 411 and has a first extension portion 311 extending into the accommodation space, and the first extension portion 311 is connected to the main circuit board 32 in the accommodation space. The structure of the first extension portion 311 extending to the accommodation space is first bent downward and then extended into the accommodation space.

[0078] In a preferred embodiment of the present application, Figure 7 , 8 As shown, the touch circuit board 31 is located on one side of the first clamping base 411 and also has a second extension portion 312, and the second extension portion 312 extends to the top of the detection through hole 416 to cover it; the touch circuit board as a whole is a transparent or translucent flexible circuit board, or, at least the second extension portion is set to be a transparent or translucent flexible circuit board. It can be understood that the detection through hole is very easy to get dusty. By setting a second extension portion on the touch circuit board to block the detection through hole, dust can be prevented from entering the detection through hole and causing contamination of the book recognition module 33. Furthermore, the book recognition module 33 generally adopts a photoelectric / image recognition module, and at least setting the second extension portion to a transparent or translucent flexible circuit board can avoid affecting the book recognition module's recognition of the book code. Generally speaking.

[0079] In a preferred embodiment of the present application, Figure 4 , 7 As shown in , 8 and 9, a switch hole 417 is provided on the first base cover 412, and a start switch 34 of the book recognition module 33 is provided in the switch hole 417;

[0080] The first clamping cover 413 is provided with a trigger structure 418 that matches the switch hole 417 . When the first clamping cover 413 is combined with the first clamping base 411 , the trigger structure 418 is just placed in the switch hole 417 and triggers the start switch 34 .

[0081] In this embodiment, the start switch 34 can be in the form of a button, and the trigger structure 418 can be a protruding structure, for example, a columnar structure. When the first clamping cover 413 and the first clamping base 411 are covered, the columnar structure can press the button in the switch hole 417, that is, trigger the start switch 34. In the above manner, the book recognition module 33 can only be triggered when the first clamping cover 413 is covered, which can reduce the occurrence of some false triggering situations. At the same time, starting the book recognition module 33 in this way can also simplify the operation of the voice book, that is, there is no need to start multiple switches.

[0082] In one embodiment of the present application, the circuit device further includes a storage circuit, a sound circuit, a power supply circuit, and a communication circuit which are arranged on the main circuit board 32 or connected to the main circuit board 32 .

[0083] Specifically, the storage circuit is used to store audio data, touch control logic, and recorded audio corresponding to the book. The sound circuit is used to output preset voice content that matches the user's touch operation; it can be understood that the sound circuit can also be an external device, and the sound book device only needs to provide a corresponding interface. The power supply circuit is used to power the circuit on the sound book; specifically, the power supply circuit can include a battery circuit, and can further include a circuit for charging the battery; optionally, the power supply circuit can also be powered in real time by an external power supply. The communication circuit is used for wireless communication with an external device. For example, it can be connected to an external display device to provide video content or video interactive information for the sound book device. In addition, the circuit device also includes a power switch and other related function buttons and a data / signal interface, which are set according to actual needs.

[0084] The embodiments of the present application described above provide a sound book device, which includes a base, a circuit device arranged on the base, and a clamping assembly. The clamping assembly can be rotated or folded relative to the base, and can be combined with the base through a quick-release structure to fix the book on the base. In this way, the sound book device can match different books and be reused. There is no need to attach other components to the book to achieve fixation. Compared with the method of fixing the book by magnetic attraction, the cost of the book can be reduced. At the same time, the clamping structure clamps the book more stably and will not produce large deviations, thereby avoiding false touches caused by this, and ensuring the accurate correspondence between the audio output content and the touch operation.

[0085] As an embodiment of the present application, a sound book system is also provided, the sound book system comprising:

[0086] The audio book device as described in any one of the above embodiments; and

[0087] A book detachably arranged on the talking book device.

[0088] Referring to the above embodiment, the book is set on the base of the talking book device and fixed by a clamping assembly. When replacing, just unfasten the clamping assembly.

[0089] In this embodiment, when the device is used, the power of the audio book device is turned on first. At this time, the audio book device plays voice prompt information. If it is equipped with a display screen or an external / plug-in display screen, it can display the boot screen. When the user fixes the book to be replaced to the audio book device, the book recognition module of the audio book device can identify the book code. The main circuit board (equipped with a processor / MCU) obtains the corresponding audio data from the storage circuit according to the book code and plays it through the generating circuit. If there is video data, it is sent to the display screen for playback. The user interacts with the keys according to the audio and video prompts, and the key array circuit on the touch circuit board feeds back the information to the main circuit board. The main circuit board further feeds back data and controls the audio and video playback accordingly.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
