[0018] The embodiments will be described in detail below with reference to the drawings.

[0019] The present embodiment provides a solar voice guide, which is applied to the tour guide side. The tour guide side can use this device to provide voice guide services for tourists.

[0020] Figure 1 FIG. shows the structural diagram of the solar voice guide. As Figure 1As shown, the solar voice guide includes a main control circuit board and a Bluetooth chip 101, which is arranged on the main control circuit board; a control unit is arranged on the main control circuit board, and the control unit is electrically connected to the Bluetooth chip 101 for controlling the Bluetooth chip to turn on the Bluetooth connection mode and the Bluetooth broadcast networking mode; a battery 102 is arranged on the main control circuit board and is electrically connected thereto; a charging interface 103 is electrically connected to the main control circuit board, and a solar charging panel 104 is electrically connected to the main control circuit board for converting solar energy into electrical energy; wherein, a power management unit 105 is further included, the power management unit is arranged on the main control circuit board, the charging interface 103 and the solar charging panel 104 are both electrically connected to the power management unit 105, and the power management unit 105 is electrically connected to the battery 102 and the Bluetooth chip 101 by wires.

[0021] Among them, the battery may include a plurality of batteries connected in parallel.

[0022] In the solar voice guide of this embodiment, in the Bluetooth broadcast networking mode, it can send broadcasts so that tourists can listen to the voice guide content. In the ordinary Bluetooth connection mode, it can also be Bluetooth-connected to its own Bluetooth devices such as mobile phones, so as to control the devices through the solar voice guide, play music or answer calls, etc., making the solar voice guide more practical. Moreover, a battery and a solar charging panel are arranged on the solar voice guide. When in large outdoor tourist attractions, it can convert solar energy into electrical energy to charge the device battery itself, saving energy and reducing costs. Combined with the equipped battery, it enables the guide in both modes to provide a longer battery life.

[0023] Specifically, the power management unit includes a first charging circuit, a second charging circuit, a discharging circuit, a first power supply circuit and a second power supply circuit. The charging interface is connected to the battery via the first charging circuit and is connected to the Bluetooth chip via the discharging circuit. The solar charging panel is connected to the battery via the second charging circuit and is connected to the Bluetooth chip via the discharging circuit. The charging interface is connected to the Bluetooth chip via the first power supply circuit, and the solar charging panel is connected to the Bluetooth chip via the second power supply circuit.

[0024] When charging through the charging interface or the solar charging panel at high power, it is possible to supply power to the Bluetooth chip while charging the battery, with priority given to charging the battery. Additionally, the battery can also supply power to the Bluetooth chip through the discharge circuit. In this embodiment, the solar voice guide includes charging paths for two charging modes, namely the charging interface and the solar charging panel, which can increase the battery life. The power management unit controls the input and output of power. In the solar charging mode, the power converted by the solar charging panel is transmitted to the battery for charging through the second power input terminal, passing through the second charging circuit and the battery charging terminal, and is directly supplied to the Bluetooth chip through the second power supply circuit and the power supply output terminal. In this way, during use, the solar power not only supplies power to the Bluetooth chip but also continuously charges the battery, ensuring the battery's power and improving the battery life. Similarly, in the charging interface charging mode, the power connected through the charging interface is transmitted to the battery for charging through the first power input terminal, passing through the first charging circuit and the battery charging terminal, and is supplied to the Bluetooth chip through the first power supply circuit and the power supply output terminal, also charging the battery and supplying power to the Bluetooth chip; the battery's power is transmitted to the Bluetooth chip through the battery discharge terminal, the discharge circuit, and the power supply output terminal.

[0025] Moreover, the power management chip also controls the power to give priority to charging the battery, that is, the power first fully charges the battery. When the battery is fully charged, it preferentially uses the power input from the solar energy or the charging interface to supply power to the Bluetooth chip; it is also possible to set a battery power threshold. For example, when the power management unit determines that the battery power is lower than 70%, it preferentially charges the battery to ensure that the battery power is not lower than 70%, so as to ensure the battery life when subsequently connecting to a mobile phone or when there is no sun.

[0026] The charging interface includes a charging control terminal, and the charging control terminal is connected to the power management unit. When the charging control terminal receives a control signal, the power management unit controls the second charging circuit to close according to the control signal. When the charging control terminal controls the charging interface to access power, the solar charging function is disconnected to ensure active charging, fast charging, and safety, and to avoid overheating during simultaneous charging.

[0027] The main control circuit board also includes an output control terminal. When the output control terminal receives a first control signal, the control unit controls the Bluetooth chip to turn on the Bluetooth connection mode according to the first control signal and wirelessly communicate with an external Bluetooth device, so that the Bluetooth chip and the external Bluetooth device can perform audio signal interaction; when the output control terminal receives a second control signal, the control unit controls the Bluetooth chip to turn on the Bluetooth networking mode according to the second control signal, so that the tour guide terminal can send audio signals through the Bluetooth chip, and the tourist terminal can receive audio signals through the Bluetooth chip.

[0028] Specifically, the output control terminals include a networking key, a power key, a volume up key, and a volume down key. The power key correspondingly triggers a first control signal, and the networking key correspondingly triggers a second control signal. For example, in the shutdown state, long-pressing the power key for 3 seconds turns on the Bluetooth connection mode, and long-pressing the networking key for 3 seconds turns on the Bluetooth networking mode. In the Bluetooth networking mode, short-pressing the volume up key increases the volume of the audio signal, and short-pressing the volume down key decreases the volume of the audio signal. In the Bluetooth connection mode, the volume up key or the volume down key can also control song switching, call connection or disconnection, etc. Figure 2 shows a specific structural diagram of the solar voice guide as a tour guide terminal. As Figure 2 shown, the solar voice guide further includes an audio input unit, an audio processing unit 106, and an audio output unit; the audio input unit includes a first built-in microphone and a second built-in microphone, namely built-in microphone 1 and built-in microphone 2 respectively. The first built-in microphone is disposed on the main control circuit board through the microphone input terminal 1 and is used to receive voice audio signals, and the second built-in microphone is disposed on the main control circuit board through the microphone input terminal 2 and is used to receive ambient audio signals; the audio processing unit 106 is connected to the Bluetooth chip 101, the audio input unit, and the audio output unit. The audio processing unit 106 performs noise reduction processing according to the ambient audio signal. The audio output unit of the tour guide terminal plays the audio signal connected to the external Bluetooth device, and the audio output unit of the tourist terminal plays the audio signal connected to the external Bluetooth device or the audio signal from the tour guide terminal.

[0029] The audio processing module can collect audio signals through the first built-in microphone and the second built-in microphone, so as to perform noise reduction processing on the two audio signals and optimize the audio signals.

[0030] The audio processing unit 106 includes a first audio input circuit, a second audio input circuit, an audio processor, an audio input and output circuit, and an audio output circuit; the first built-in microphone is connected to the audio processor via the first audio input circuit and is connected to the Bluetooth chip via the audio input and output circuit, and the second built-in microphone is connected to the audio processor via the second audio input circuit; the Bluetooth chip is connected to the audio processor via the audio input and output circuit and is connected to the audio output unit via the audio output circuit.

[0031] When the solar voice guide is applied to the tour guide side, the solar voice guide further includes a microphone interface, the audio processing unit further includes a third audio input circuit, the microphone interface includes an audio input control terminal, and the audio input control terminal is connected to the audio processing unit. When the audio input control terminal receives a control signal, the audio processing unit controls the first audio input circuit and the second audio input circuit to be turned off according to the control signal, and an external microphone 3 connected to the microphone interface is connected to the audio processor via the third audio input circuit and then connected to the Bluetooth chip via the audio input / output circuit.

[0032] On the tour guide side, an external microphone device can be connected through the microphone interface to collect audio signals, providing a more flexible audio input method for users and better meeting the needs of users.

[0033] When applied to the tour guide side, the solar voice guide further includes a radio frequency amplifier and a voltage regulator chip, and the radio frequency amplifier is electrically connected to the Bluetooth chip and the voltage regulator chip. The signal strength is enhanced through the radio frequency amplifier and the voltage regulator chip to make the Bluetooth broadcast more stable.

[0034] The audio output unit includes a first speaker and a second speaker. The solar voice guide includes a hat body and a brim. The main control circuit board, the charging interface, the microphone interface, the networking key, the power key, the volume up key, the volume down key, the first built-in microphone, the second built-in microphone, the first speaker and the second speaker are all arranged on the hat body, and the solar charging panel is arranged on the brim.

[0035] By designing the language guide in the shape of a hat, the solar voice guide is convenient to wear, which can not only provide a sunshade function for users during the process of visiting scenic spots, but also meet the guide requirements.

[0036] The solar voice guide further includes an antenna base, a signal line and an external antenna. The antenna base is arranged on the main control circuit board and is electrically connected to the Bluetooth chip. The external antenna is arranged at the far end of the brim, and one end of the signal line is electrically connected to the antenna base and the other end extends along the brim to the far end and is electrically connected to the antenna.

[0037] Exemplarily, the solar voice guide may further include a software storage chip, and the software storage chip is connected to the interface on the Bluetooth chip to provide a software program for the Bluetooth chip.

[0038] Exemplarily, the solar voice guide may further include other modules, such as a type-c charging port, an overvoltage protection chip, a charging path management (for controlling the switching between solar charging and charging port charging), a filter, etc. The present embodiment is not limited thereto.

[0039] The solar voice guide in the above embodiments can be applied to the guide side and the tourist side to provide voice guide services for tourists. When the solar voice guide is used as the tourist side, its specific structure can refer to the solar voice guide as the guide side above, which will not be elaborated here.

[0040] Based on the above solar voice guide, this embodiment also provides a voice guide method, which can control the solar voice guide, and based on solar energy, provide a guide method with both Bluetooth broadcast and Bluetooth pairing functions for users, which can enhance the functions of the guide device and improve the practicality and usage efficiency of the voice guide.

[0041] Exemplarily, this voice guide method can be applied to the solar voice guide on the guide side, or to the solar voice guide on the tourist side, or for the interaction between the guide side and the tourist side.

[0042] On the guide side, this voice guide method may include the following steps: Step 10: Start the Bluetooth connection mode of the Bluetooth chip in the solar voice guide or start the Bluetooth broadcast mode of the Bluetooth chip according to the user's control operation on the function button in the solar voice guide.

[0043] The user can control the function button to be turned on or off, and the control operation is the operation of controlling the function button to be turned on or off. Whether to enable the Bluetooth connection mode or the Bluetooth broadcast mode can be determined according to the user's control operation on the function button.

[0044] Step 20: In the Bluetooth connection mode, connect to the Bluetooth client through the Bluetooth chip, receive the audio transmitted by the Bluetooth client, and play it.

[0045] The Bluetooth client can include various clients with Bluetooth functions, such as mobile phones, smart watches, bracelets, etc., and this embodiment is not limited thereto. When the solar voice guide on the guide side is connected to the user's Bluetooth client, the solar voice guide can replace the Bluetooth client to play music, answer calls, and realize various Bluetooth control functions.

[0046] Step 30: In the Bluetooth broadcast mode, transmit a Bluetooth broadcast signal with a fixed frequency.

[0047] The fixed frequency can be preset and provided to the user for easy connection. The client with Bluetooth function can receive the Bluetooth broadcast signal to listen to the guide voice on the guide side.

[0048] In an exemplary embodiment, when the tourist device receives the Bluetooth broadcast signal of the fixed frequency, it sends the tour guide device number to the tourist device, and the tour guide device number corresponds to the solar voice guide. Different tour guide devices may have different tour guide device numbers. When the tourist device answers the Bluetooth broadcast signal of the tour guide device, it can send the tour guide device number to the tourist device, which is convenient for the tourist to verify whether it corresponds to the content they want to listen to.

[0049] Furthermore, this embodiment also provides a voice guide method, which is applied to the solar voice guide as the tourist device.

[0050] At the tourist device, the method includes: Step 40: Start the Bluetooth connection mode of the Bluetooth chip in the solar voice guide or start the Bluetooth broadcast mode of the Bluetooth chip according to the user's control operation on the function keys in the solar voice guide.

[0051] Step 50: In the Bluetooth connection mode, connect to the Bluetooth client through the Bluetooth chip, receive the audio transmitted by the Bluetooth client, and play it.

[0052] Step 60: In the Bluetooth broadcast mode, receive the Bluetooth broadcast signal of the fixed frequency.

[0053] When receiving the Bluetooth broadcast signal of the fixed frequency, receive the tour guide device number; verify the tour guide device number. When the tour guide number is incorrect, restart the Bluetooth broadcast mode and receive the tour guide device number again.

[0054] The tour guide can tell the tourist the tour guide device number corresponding to the explanation content and the fixed frequency of the tour guide device. When the tourist connects to this fixed frequency, they can receive the broadcast tour guide device number. The tourist can verify whether the tour guide device number is consistent with the tour guide device number corresponding to the required explanation content. In the case of inconsistency, turn off the Bluetooth broadcast mode of the tourist device, and then restart the Bluetooth broadcast mode after changing the position, reconnect to the Bluetooth signal, and listen to the Bluetooth broadcast. This process can be repeated until the tourist device connects to the correct tour guide device.
