[0019] This utility model discloses an advertising player for wireless audio download, such as... Figures 1-4As shown, the advertising player includes a transmitter 1 and a receiver 2. The transmitter 1 transmits data wirelessly to the wireless receiver 21 in the receiver 2 via radio frequency pairing or Bluetooth connection through a wireless transmitter 11. The transmitter 1 includes a first signal processing module 12 and a first audio player 13. The first signal processing module 12 is connected to both the wireless transmitter 11 and the first audio player 13. The receiver 2 includes a second signal processing module 211 and a second audio player 22. The signal input terminal of the second signal processing module 211 is connected to the wireless receiver 21. The second signal processing module 211 is also connected to both the second audio player 22 and the playback control module 23. The first signal processing module 12 and the wireless transmitter 11 are both connected to a power module 14, and the second signal processing module 211 and the playback control module 23 are both connected to a power module 24.
[0020] It should be noted that: the transmitter 1 of the first type of advertising player is a remote control. The wireless transmitter 11 and the wireless receiver 21 achieve wireless data transmission through radio frequency pairing. When transmitting audio data to the receiver 2, the audio data is first downloaded to the remote control. The audio data enters the first signal processing module 12 through the signal input terminal of the first signal processing module 12. The remote control plays the audio content on the first audio player 13 at the same time as sending the audio content, thus serving as a monitoring function. After the audio content is finished playing, the power of the remote control can be turned off through the power module 14 to end the transmission. After the wireless transmitter 11 and the wireless receiver 21 form a wireless connection, the transmitter 1 starts the audio playback function. The receiver 2 receives the audio data and automatically downloads and stores it in the second signal processing module 211. The playback of the audio content of the receiver 2 is controlled by the playback control module 23. The playback action command is subject to human body sensing, light control, magnetic control, sound control and manual control, realizing free switching between automatic and manual control, which can meet the advertising, welcoming, display, reminder and warning function requirements of various occasions. When the transmitter 1 is turned off, the transmitter 1 and the receiver 2 will automatically disconnect, and the entire audio signal transmission process is completed.
[0021] When the mobile phone acts as transmitter 1, it needs to connect to receiver 2 via Bluetooth before sending audio content. After the mobile phone's Bluetooth and receiver 2's Bluetooth are connected, the mobile phone plays the audio content, which is automatically downloaded to receiver 2. Once playback is finished, the Bluetooth connection is disconnected to complete the sending and receiving process.
[0022] This advertising player uses radio signals to transmit audio data, eliminating the need for a wired connection to the internet. Users can simply download the audio data to a remote control or mobile phone to wirelessly change the audio content. This convenient operation eliminates the need for a USB cable to connect to a computer or insert a card when changing audio content, avoiding obstruction caused by the player's waterproof sealing or installation at a high location.
[0023] It needs to be further explained that, such as Figure 3 and Figure 4 As shown, the first signal processing module 12 includes a first CPU 121 and a flash memory 122. The signal output terminal of the first CPU 121 is connected to the wireless transmitter 11, the flash memory 122 and the first audio player 13 respectively. The second signal processing module 211 includes a second CPU 212 and a memory 213. The signal input terminal of the second CPU 212 is connected to the wireless receiver 21 respectively. The signal output terminal of the second CPU 212 is connected to the playback control module 23, the memory 213 and the second audio player 22.
[0024] The audio data enters the first signal processing module 12 through its signal input terminal and is transmitted to the first CPU 121. The first CPU 121 transmits the audio data to the flash memory FLASH 122 for storage. Then, the first CPU 121 reads the audio data from the flash memory FLASH 122 and transmits it to the first audio player 13 and the wireless transmitter 11 respectively. After receiving the audio data, the first audio player 13 plays the audio according to its content. Simultaneously, after digital-to-analog conversion, the audio data is wirelessly transmitted to the wireless receiver 21 via the wireless transmitter 11. The wireless receiver 21 receives the audio signal, performs analog-to-digital conversion, and transmits it to the second CPU 212. The second CPU 212 transmits the audio data to the memory 213 for storage for future retrieval. Then, the second CPU 212 transmits the audio data to the second audio player 22. After the playback control module 23 generates a control command and transmits it to the second audio player 22, the second audio player 22 starts playing the audio data. The entire audio data transmission process is achieved wirelessly, and the steps are simple.
[0025] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, the signal transmission line of the first CPU 121 is connected to a pairing module 17, and the signal transmission line of the second CPU 212 is connected to a pairing module 27. The pairing module 17 includes a pairing switch 171 and an indicator light 172. The pairing switch 171, the indicator light 172, and the first CPU 121 transmit control signals through the same signal transmission line. The pairing module 27 includes a pairing switch 271 and an indicator light 272. The pairing switch 271, the indicator light 272, and the second CPU 212 transmit control signals through the same signal transmission line.
[0026] In the first type of advertising player, a transmitter 1 and a receiver 2 are combined as a product set. Each set is equipped with a corresponding password, and transmitter 1 and receiver 2 must be paired with the required password information before installation to avoid signal transmission errors by transmitter 1 or reception errors by receiver 2. When the transmitter 11 pairs with the wireless receiver 21 using the password, the first CPU 121 sends a matching signal to the wireless transmitter 11 via pairing switch 171 and pairing switch 271 respectively. The wireless transmitter 11 then transmits a pairing signal to the receiver 2. After the receiver 2 receives a signal from transmitter 1 with the same password, both indicator lights 172 and 272 will light up. After being turned on, transmitter 1 plays audio through the first audio player 13, while wireless transmitter 11 transmits audio data to receiver 2 wirelessly. Wireless receiver 21 in receiver 2 receives the audio data and automatically downloads and stores the audio content through the second CPU 212. In addition, wireless transmitter 11 and wireless receiver 21 achieve wireless data transmission through radio frequency pairing. The operating frequency band for wireless connection between wireless transmitter 11 and wireless receiver 21 through radio frequency pairing is 315MHz or 433MHz. Providing two operating frequency bands for radio frequency pairing allows connection to the other operating frequency band to achieve wireless connection between wireless transmitter 11 and wireless receiver 21 when signal interference occurs during radio frequency pairing, reducing the impact of signal interference on radio frequency pairing operation.
[0027] It needs to be further explained that, such as Figure 2 and Figure 5 As shown, the wireless transmitter 11 and the wireless receiver 21 are connected via Bluetooth to achieve wireless data transmission. The wireless transmitter 11 is a Bluetooth transmitter 18, and the wireless receiver 21 is a Bluetooth receiver 28.
[0028] In the second type of advertising player, the first signal processing module 12 controls the Bluetooth transmitter 18 to send a connection request signal to the Bluetooth receiver 28. After the Bluetooth receiver 28 grants the connection request, the Bluetooth transmitter 18 and the Bluetooth receiver 28 form a Bluetooth connection, thereby enabling a smart device, such as a mobile phone, to function as a transmitter of audio data in the advertising player. A product consists of one transmitter 1 and one receiver 2, each equipped with a corresponding password. Before installation, transmitter 1 and receiver 2 must be paired with the required password information to prevent signal transmission errors by transmitter 1 or reception errors by receiver 2. The transmitter uses the wireless transmitter 11 and... When the Bluetooth receiver 28 of the receiver is paired with a password, the first CPU 121 sends a pairing signal to the Bluetooth transmitter 18 via pairing switch 171 and pairing switch 271 respectively. The wireless transmitter 11 transmits a pairing signal to the receiver 2. After the receiver 2 receives a signal from the transmitter 1 with the same password, both indicator lights 172 and 272 will light up. After both indicator lights 172 and 272 are lit, the transmitter 1 plays audio through the first audio player 13. At the same time, the wireless transmitter 11 sends audio data to the receiver 2 wirelessly. The Bluetooth receiver 28 in the receiver 2 receives the audio data and automatically downloads and stores the audio content through the second CPU 212.
[0029] It needs to be further explained that, such as Figure 3 and Figure 4 As shown, the power module 14 includes a first power supply 15 and a power switch 16. The output of the first power supply 15 is connected to the power switch 16 via a line. The power switch 16 is connected to the first signal processing module 12 and the wireless transmitter 11 via power transmission lines. The power module 24 includes a second power supply 25 and a power switch 26. The output of the second power supply 25 is connected to the power switch 26 via a line. The power switch 26 is connected to the second signal processing module 211 and the playback control module 23 via power transmission lines.
[0030] Specifically, power switch 16 can control the power transmission line between the first power supply 15 and the first signal processing module 12 and the wireless transmitter 11, thereby controlling the operation of the first signal processing module 12, the first audio player 13 and the wireless transmitter 11, and thus controlling the operation of the entire transmitter 1; while power switch 26 can control the power transmission line between the second power supply 25 and the second signal processing module 211 and the wireless transmitter 11, thereby controlling the operation of the second signal processing module 211, the wireless receiver 21 and the second audio player 22, and thus controlling the operation of the entire receiver 2.
[0031] It needs to be further explained that, such as Figure 4 As shown, the playback control module 23 consists of a sensing end 231 that is controlled by human body sensing, light control, magnetic control, sound control and manual control, and a control chip 232. The sensing end 231 is connected to the control chip 232 to transmit command signals, and the sensing end 231 is connected to the second CPU 212 to transmit command signals.
[0032] Among them, the sensing terminal 231, which is subject to human body sensing, light control, magnetic control, sound control and manual control, can generate control commands in a variety of ways and then transmit them to the control chip 232. The control chip 232 controls the second audio player 22 to play audio data, making the operation of the second audio player 22 more diversified.
[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
