[0061] With the development of wireless communication technology, wireless remote control is more and more widely used in daily work and life. For example, a wireless page turning pen can be used as a wireless remote control device for teaching or conference. The wireless page turning pen is connected with a PC page turning receiver to realize the page turning or zooming function of the PC.

[0062] However, the related art has the problem of less functions in implementation.

[0063] Therefore, the embodiments of the present application provide a wireless remote control device circuit and device. The wireless remote control device circuit and device can realize the functions of device page turning, MP3 storage and playing, sound amplification, recording, etc. by the following structure: the main control module 10 is connected with the page turning key module 70, the page turning communication module 20 is connected with the main control module 10 and connected with a page turning receiving device, the data input module 30 and the storage module 40 are respectively connected with the main control module 10, and the sound input module 50 and the sound communication module 60 are respectively connected with the main control module 10. Thus, the functions of the wireless remote control device circuit and device are enriched, the wireless remote control with multiple functions is realized, and the cost of the wireless remote control device is reduced.

[0064] In an exemplary embodiment, Figure 1 The structure diagram of the wireless remote control device circuit provided by the embodiments of the present application is shown in FIG. 1. Figure 1 As shown in FIG. 1, the wireless remote control device circuit includes a main control module 10, a page turning communication module 20, a data input module 30, a storage module 40, a sound input module 50, and a sound communication module 60. It should be noted that Figure 1 In the embodiments of the present application, the main control module 10 is connected with other modules through one port. However, in actual application, the main control module 10 can be connected with other modules through two or more ports according to actual needs, that is Figure 1 The connection relationship does not limit the present application.

[0065] Specifically, the main control module 10 is used to connect the page turning key module 70.

[0066] Specifically, the page turning communication module 20 is connected with the main control module 10 and is further used to connect a page turning receiving device. The page turning receiving device is used to execute the page turning function.

[0067] The main control module 10 can be an MCU (Microcontroller Unit) and can be used as the central control module of the wireless remote control device circuit. The page turning key module 70 can be the key module of the wireless remote control device. It can be understood that the wireless remote control device can include the wireless remote control device circuit and the page turning key module 70.

[0068] The page turning communication module 20 can be a module for communicating with a device requiring page turning, and can be used to receive a page turning signal sent by the master control module 10 and transmit the page turning signal to a page turning receiving device. The page turning receiving device can be a device requiring page turning, for example, a personal computer, and the page turning function of a PPT or the like can be implemented in the personal computer. The page turning receiving device can also be a receiver with a USB interface, which can be used to be plugged into a computer to drive the computer to turn pages.

[0069] The page turning key module 70 can include physical keys, for example, Figure 2 The physical structure of the wireless remote control device provided in the embodiments of the present application is shown in FIG. 1, which shows that the page turning keys 90 with triangular symbols can be used for page turning, wherein the up page turning key 901A can be used for up page turning, and the down page turning key 901B can be used for down page turning. Figure 2

[0070] Exemplarily, the page turning key module 70 can be connected with the keys of the master control module 10, that is, the execution instruction of the master control module 10 can be driven through the page turning key module 70. The master control module 10 can output a corresponding page turning signal to the page turning communication module 20, which is sent to the page turning receiving device through the page turning communication module 20, so as to enable the page turning receiving device to implement the page turning function. In this way, the execution instruction of the master control module 10 can be driven through the page turning key module 70, so that the master control module 10 outputs a page turning signal to the page turning receiving device through the page turning communication module 20 to control page turning. Through the above structure, the wireless remote control device can implement the page turning function.

[0071] It should be noted that the page turning function can be implemented through the technology of a related page turning device.

[0072] In actual application, when the down page turning key as shown in FIG. 2 is pressed, the master control module 10 can detect the level change of the key connected with the down page turning key, transmit the page turning command to the page turning communication module 20 through the serial port, and the page turning communication module 20 can wirelessly transmit the command to the USB receiving module of the page turning receiving device to implement down page turning of a document. Figure 2 In actual application, when the down page turning key as shown in FIG. 2 is pressed, the master control module 10 can detect the level change of the key connected with the down page turning key, transmit the page turning command to the page turning communication module 20 through the serial port, and the page turning communication module 20 can wirelessly transmit the command to the USB receiving module of the page turning receiving device to implement down page turning of a document. Figure 2 In actual application, when the up page turning key as shown in FIG. 3 is pressed, the master control module 10 can detect the level change of the key connected with the up page turning key, transmit the up page turning command to the page turning communication module 20 through the serial port, and the page turning communication module 20 can wirelessly transmit the command to the USB receiving module of the page turning receiving device to implement up page turning of a document.

[0073] Specifically, the data input module 30 is used to receive an externally input sound file.

[0074] Specifically, the storage module 40 is connected with the data input module 30 through the master control module 10 and is used to store the sound file.​

[0075] The data input module 30 can be a module for receiving data input, for example, can be a USB interface, etc. The storage module 40 can be used to store the data input through the data input module 30.

[0076] The host module 10 is connected to the data input module 30 and the storage module 40, respectively. For example, the host module 10 can be connected to the data input module 30 through a serial port, and the host module 10 can be connected to the storage module 40 through an SPI bus.

[0077] Specifically, the host module 10 can be connected to the data input module 30 through the data input module 30, and the host module 10 can be connected to the storage module 40 through the data input module 30. The host module 10 can transmit the sound file to the host module 10, and the host module 10 can transmit the sound file to the storage module 40 after processing, so as to realize the storage of the sound file. For example, the host module 10 can process the sound file into a format that the storage module 40 can store, and then transmit the sound file to the storage module 40. It can be understood that the storage module 40 can not only store sound files, but also store other data files, so that the wireless remote control device can have the function of storing data, that is, it can realize the function of simulating a U disk.

[0078] The host module 10 can be connected to the data input module 30 through the data input module 30, and the host module 10 can be connected to the storage module 40 through the data input module 30. The host module 10 can transmit the sound file to the host module 10, and the host module 10 can transmit the sound file to the storage module 40 after processing, so as to realize the storage of the sound file. For example, the host module 10 can process the sound file into a format that the storage module 40 can store, and then transmit the sound file to the storage module 40. It can be understood that the storage module 40 can not only store sound files, but also store other data files, so that the wireless remote control device can have the function of storing data, that is, it can realize the function of simulating a U disk.

[0079] In practical application, the host module 10 can be connected to the data input module 30 (such as a USB serial port) for data exchange, and the host module 10 can be connected to the storage module 40 (such as a TF storage chip 401) for data exchange. When the USB data line is inserted into the TYPE_C interface, the TF storage chip 401 can be displayed in the form of a U disk on the host computer, and the audio file or other data file can be stored in the TF storage chip 401.

[0080] It should be noted that the transmission and processing of data between the data input module 30, the storage module 40 and the host module 10 can be realized through the U disk storage function, that is, the above data transmission and processing can be realized by the existing related technology.

[0081] Specifically, the sound input module 50 is used to receive external input sound signals.

[0082] Specifically, the sound communication module 60 is connected to the sound input module 50 and the storage module 40 through the host module 10, and is also used to connect the sound playing device 80. The sound playing device is used to play the sound corresponding to the sound file and / or the sound signal.

[0083] The audio input module 50 can be a module for receiving audio, such as a module containing microphone circuitry. The audio communication module 60 can be a module for transmitting audio signals between the main control module 10 and the audio playback device. The audio playback device can be a device for amplifying sound.

[0084] For example, the main control module 10 is connected to the sound input module 50 and the sound communication module 60 respectively. The sound input module 50 receives external sound signals (such as human voices). The main control module 10 can process the sound signals and transmit them to the sound playback device through the sound communication module 60. The sound playback device can play the sound signals, thus realizing the sound amplification function. In other words, the wireless remote control device can realize the function of a microphone.

[0085] Optionally, the audio files in the storage module 40 can also be processed by the main control module 10 and transmitted to the audio playback device through the audio communication module 60, so that the audio playback device can play the audio files in the storage module 40. In this way, a function similar to MP3 can be achieved through the wireless remote control device circuit, further enriching the function of the wireless remote control device.

[0086] In some examples, the audio signal input through the audio input module 50 can be processed by the main control module 10 and stored in the storage module 40 to realize the recording function of the wireless remote control device.

[0087] It is understood that the above data processing can be implemented based on relevant technologies in the prior art, and data processing is not considered an improvement of this application.

[0088] In practical applications, when playing MP3 files (audio files), after dragging the audio file (audio file) into the TF storage chip 401 via the USB interface, press... Figure 2 The OK button shown in the middle leads to the built-in storage playback menu. By clicking the menu and selecting the open command, the main control module 10 can decode and play the MP3 file in the TF storage chip 401. At the same time, the audio file can be transmitted to the sound communication module 60 for modulation via the I2S standard interface and then sent to the sound playback device to realize the MP3 playback function.

[0089] In this embodiment, the wireless remote control device circuit with the above-described structure can integrate multiple functions such as device page turning, MP3 storage and playback, and sound amplification into the wireless remote control device, thereby making the wireless remote control device multifunctional.

[0090] In some specific embodiments, the wireless remote control device circuit can be applied to a wireless page turning pen in a teaching scenario, which can be connected with a PPT page turning receiver to realize PPT page turning or zooming function of a computer, and when connected with a wireless computer end voice receiving device (sound playing device), the microphone voice amplification function can be realized at the same time. Meanwhile, the wireless page turning pen can realize MP3 playing function and recording function, and the teaching audio can be played through the wireless page turning pen. Thus, the use of various teaching tools can be reduced, the cost can be reduced, and the convenience of teaching can be improved.

[0091] Meanwhile, the wireless remote control device circuit can be applied to a microphone device of a KTV, which can realize wireless voice amplification function, and through the page turning function, the function of remotely selecting a song can be realized. And through the microphone device with the wireless remote control device circuit, the singing recording function can be realized, so that the use of recording tools and song page turning tools can be reduced, and the application is more convenient.

[0092] In an exemplary embodiment, Figure 3 The structural schematic diagram of the sound communication module 60 provided in the embodiment of the present application is shown in Figure 3 Based on Figure 1 , the sound communication module 60 is described in detail, specifically, the sound communication module 60 can include: a sound communication chip 601 and a sound communication antenna 602, it should be noted that Figure 3 The pins in the sound communication chip 601 related to the units provided in the embodiment of the present application are shown in the figure, the pins and peripheral circuits not shown in the sound communication chip 601 can be set according to actual conditions, Figure 3 The examples shown in the figure are not intended to limit the present application.

[0095] Among them, the sound communication chip 601 can be a chip for processing and transmitting sound signal. The sound communication antenna 602 can be an antenna for transmitting audio signal.

[0096] Exemplarily, the audio port of the sound communication chip 601 can be connected with the audio interface of the master module 10. For example, the sound communication chip 601 and the master module 10 can be connected through the I2S standard interface MCLK, LRCK, BCLK, DO, and DIN. Among them, MCLK is the I2S master clock, LRCK is the I2S left and right channel clock, BCLK is the I2S serial audio clock, DO is the I2S audio data output, and DIN is the I2S audio data input.

[0097] Referring to Figure 3 , the sound communication chip 601 can be connected with the RF antenna through the RF_N and RF_P ports, and the RF antenna can serve as the sound communication antenna 602. An oscillation circuit including an inductor and a capacitor can be arranged between the sound communication chip 601 and the RF antenna.

[0098] In the embodiment, through the structure of the wireless remote control device circuit, the sound amplification of the human voice and the function of playing the MP3 file of the wireless remote control device can be effectively realized, so that the function of the wireless remote control device can be enriched.

[0102] Among them, the first crystal oscillator 603 can be a crystal oscillator arranged at the periphery of the sound communication chip 601.

[0103] Exemplarily, the two ends of the first crystal oscillator 603 are respectively connected with the X0 port and the X1 port of the sound communication chip 601. Among them, the X0 port can be the input end of the oscillation circuit, and the X1 port can be the output end of the oscillation circuit. The two ends of the first crystal oscillator 603 are further respectively connected with one end of a capacitor, and the other end of the capacitor is used for grounding. For example, one end of the first crystal oscillator 603 is connected with one end of the capacitor CTA1, the other end of the first crystal oscillator 603 is connected with one end of the capacitor CTB1, and the other end of the capacitor CTA1 and the other end of the capacitor CTB1 are both used for grounding.

[0104] In this way, through the above structure, the sound communication chip 601 can be provided with stable frequency through the crystal oscillator, so that the sound chip can work stably, thereby ensuring the realization of the sound amplification of the human voice and the function of playing the MP3 file, and further ensuring the multifunctionality of the wireless remote control device.

[0105] In an exemplary embodiment, Figure 4This is a schematic diagram of the structure of the page-turning communication module 20 provided in the embodiments of this application, as shown below. Figure 4 As shown, in Figure 1 Based on this, the page-turning communication module 20 will be described in detail. Specifically, the page-turning communication module 20 may include: a page-turning communication chip 201 and a page-turning communication antenna 202. It should be noted that... Figure 4 The diagram shows pins related to the unit provided in the embodiment of this application in the page-turning communication chip 201. The pins and peripheral circuits of the page-turning communication chip 201, which are not shown, can be configured according to actual conditions. Figure 4 The examples shown are not intended to limit this application. Wherein:

[0106] The page-turning communication chip 201 has its receiving port and transmitting port connected to the main control module 10, respectively.

[0107] The page-turning communication antenna 202 is connected to the output end of the page-turning communication core and is also used to connect to the page-turning receiving device.

[0108] The page-turning communication chip 201 can be used as a chip for wireless mouse communication, that is, it can be used as a communication chip for page-turning control. The page-turning communication antenna 202 can be used as an antenna for wireless communication.

[0109] For example, the receiving port of the page-turning communication chip 201 can be connected to the transmitting port of the main control module 10, and the transmitting port of the page-turning communication chip 201 can be connected to the receiving port of the main control module 10. For instance, the RXD port of the page-turning communication chip 201 can be connected to the TXD port of the main control module 10, and the TXD port of the page-turning communication chip 201 can be connected to the RXD port of the main control module 10. The page-turning communication antenna 202 is connected to the antenna output port of the page-turning communication chip 201, and the page-turning signal of the page-turning communication chip 201 can be transmitted to the page-turning receiving device through the page-turning communication antenna 202.

[0110] In practical applications, refer to Figure 4 The page-turning communication chip 201 can communicate with the main control module 10 through the USBDP pin and the USBDN pin.

[0114] The two ends of the second crystal oscillator 203 are further respectively connected to ground through capacitors.

[0115] The second crystal oscillator 203 can be a crystal oscillator arranged at the periphery of the page-turning communication chip 201.

[0116] For example, one end of the first crystal oscillator 603 is connected to one end of a capacitor C14, the other end of the first crystal oscillator 603 is connected to one end of a capacitor C15, and the other end of the capacitor C14 and the other end of the capacitor C15 are both connected to ground.

[0117] Thus, through the above structure, the page-turning communication module 20 can be provided with stable frequency by the crystal oscillator, and the stable operation of the page-turning communication module 20 can be ensured, so that the stable wireless remote control page-turning function can be ensured, and the multi-function stability of the wireless remote control device can be ensured.

[0118] Optionally, the page-turning communication antenna 202 is a spiral antenna.

[0119] In actual application, the sound communication antenna 602 is usually a 2.4G wireless voice antenna, and if the page-turning communication antenna 202 is a PCB antenna, resonance can be easily formed with the sound communication antenna 602, audio interference can be generated, and the circuit board is not easy to arrange.
