Description

Technical Field

[0001] This utility model belongs to the field of radio communication technology improvement, and in particular relates to a separate radio based on a radio receiver and a control listening end. Background Technology

[0002] A radio is a traditional wireless receiver used for listening to news, radio broadcasts, and for disaster relief and other purposes. Its simple operation makes it popular with middle-aged and elderly users. Traditional radios integrate radio reception, audio control, and sound output into a single unit. This design has a significant drawback in certain situations, such as indoors or in environments with severe radio signal jamming. In these conditions, the number of radio stations received will drastically decrease, or stations may be unavailable. For example, shortwave reception will be virtually impossible indoors, medium wave reception will be significantly impaired under a home air conditioner, and FM broadcasts will also be drastically reduced.

[0003] In indoor or electromagnetically shielded / interference environments, building obstruction and interference significantly reduce the reception capability of medium wave and short wave signals. For example, the indoor reception effect of short wave signals is only 0-50% of that outdoors. In the case of traditional radios where the antenna and receiver are integrated, it is not possible to flexibly change the antenna receiving position to improve the quality of broadcast signals.

[0006] The radio receiver is used to receive radio signals transmitted by the wireless broadcasting station and to digitally process the received radio signals to generate digital audio / frequency / field strength / signal-to-noise ratio signals for short-distance transmission.

[0007] The control receiver is used to receive high-frequency digital signals produced by the radio receiver, and demodulate the high-frequency digital signals to restore them into digital audio / frequency / field strength / signal-to-noise ratio signals for the receiver to use and broadcast.

[0014] A further technical solution of this utility model is that both the power supply unit and the power supply module use rechargeable lithium batteries.

[0015] The beneficial effects of this utility model are as follows: By using a separate short-range communication design for the receiving end and the listening end, the problems of weak broadcast signals and inflexible equipment movement in shielded environments are eliminated. The receiving end is placed in an unshielded environment, and the received signal is transmitted to the listening end for playback using short-range high-frequency signal communication, allowing users to select and listen.

[0032] like Figure 1-13 As shown, the present invention provides a separate radio based on a radio receiver and a control receiver, which includes a radio receiver and a control receiver. The radio receiver is connected to the control receiver via data communication.

[0038] The tuning module is used to tune, filter, and amplify the received signal to ensure the quality of the received signal.

[0039] The demodulation module is used to restore the received analog signal to its original digital information. During communication, the modulator at the transmitting end converts the digital signal into an analog signal for transmission over an analog channel. The demodulation module at the receiving end is responsible for restoring these analog signals to their original digital form.

[0040] A microprocessor is used to calculate and process received data, execute instructions one by one according to the program instruction set, control the collaborative work between various modules, communicate with various input and output devices, change the execution order of the program according to conditions and program logic, and implement loop and branch structures through jump, call and return instructions, thereby executing complex logic.

This reduces the need for physical cables and connections, lowering the cost of device installation, layout, and maintenance.

[0042] Power supply modules / units provide operating energy to various devices, including voltage conversion, regulation and stabilization, filtering and noise suppression, protection mechanisms, input / output isolation, thermal management, and packaging and compatibility. Through these functions, power supply modules ensure stable operation of electronic equipment under various operating conditions.

[0043] The control receiver includes a control unit, a display unit, an audio processing unit, a communication unit, a voice unit, and a power supply unit.

[0045] A control unit is used to retrieve instructions from memory, analyze instructions, and execute instructions. A control unit is a control component that implements one or more control laws.

[0046] An Audio Processing Unit (APU) is an electronic device or software used to analyze, modify, enhance, and convert audio signals to improve their quality or meet specific needs. Its internal structure typically includes input and output sections and offers various processing functions such as parametric equalization, crossover, delay, and mixing.

[0047] The display unit is used to display information, provide an interactive interface, and perform data acquisition and communication functions. Through a combination of LEDs and driver circuits, it presents digital, text, and image information to the user in a visual manner. It receives data through different input methods and provides multi-level connection expansion, such as serial input, parallel input, and RS485 communication input.

[0050] The communication module / unit employs a wireless communication module, which uses one or more of the following communication protocols: Bluetooth, Wi-Fi, and Zigbee. Bluetooth, Zigbee, and Wi-Fi are radio technologies that support short-range communication between devices.

[0051] A solar panel can be added to the antenna receiver to charge the battery, and it can also directly power the device during the day and charge the battery so that the device can be powered by the battery at night.

[0052] The receiving device can be a smartphone with a radio app installed, a radio, or a media player and audio equipment with radio functionality.

[0053] In this application, the circuit principle structure of each module / unit in the radio receiver and the control listening end all adopt mature circuit structure. The main inventive point of this application is to separate the receiving antenna from the listening end, so that the antenna and the listening end can be connected through short-range communication, breaking the traditional integrated structure of the radio.

[0054] The radio antenna is assembled separately into an independent main radio receiver. In use, the radio receiver and radio control unit can be used together or separately. The radio receiver communicates with the control unit via short-range communication, which can be achieved through one or more of the following protocols: Bluetooth, Wi-Fi, or Zigbee. During communication, one radio receiver can connect to multiple control units simultaneously. The radio receiver is placed in a location with low shielding / interference, such as outdoors, to increase the number of radio stations it can receive. The radio receiver converts the received radio signals into short-range transmission signals and transmits them via a sharing mechanism. Any device with a listening function within the transmission range can connect to the radio receiver. The receiving unit then reconstructs the received signal into a radio broadcast signal and broadcasts and displays the listening frequency accordingly. This avoids the problem of limited radio station reception due to weak indoor signals.
