[0029] Throughout the specification, reference to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. Therefore, the phrases "in one embodiment", "in some embodiments", or "in some embodiments" appearing in various places throughout the specification are not all referring to the same embodiment. Furthermore, particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0030] As shown in Figure 1 The present application provides a module with offline voice and radio frequency remote control. The module with offline voice and radio frequency remote control provided by the present application is suitable for air conditioners.

[0031] The embodiment provides an offline voice and radio frequency remote control module, which comprises a control circuit 10, a communication circuit 11, a module circuit 12, a microphone circuit 13 and a speaker power amplifier circuit 14.

[0032] In some embodiments, one end of the communication circuit 11 is electrically connected with the control circuit 10, and the other end of the communication circuit 11 is electrically connected with the module circuit 12. The control circuit 10 receives instructions from the module circuit 12 through the communication circuit 11. The instructions of the module circuit 12 include offline voice instructions and radio frequency remote control instructions. For the received instructions, the control circuit 10 needs to be decoded and processed. The communication circuit 11 is responsible for transmitting the instructions processed by the module circuit 12 to the control circuit 10; after the control circuit 10 performs an operation, the state information of the system is fed back to the module circuit 12 through the communication circuit 11.

[0033] As an example, when a voice instruction is received, the control circuit 10 analyzes the specific operation command, such as adjusting the temperature, switching the mode and the like; when a radio frequency remote control instruction is received, the corresponding operation is also identified. When a user issues an instruction of 'turning on the air conditioner' through offline voice, the module circuit 12 identifies the instruction, and then transmits the instruction of 'turning on the air conditioner' to the control circuit 10 through the communication circuit 11, and the control circuit 10 performs the operation of turning on the air conditioner. After the air conditioner receives the instruction of 'adjusting the temperature to 26 DEG C' and performs the operation, the control circuit 10 can feed back the state information that the current temperature has been adjusted to 26 DEG C to the module circuit 12 through the communication circuit 11, and the module circuit 12 can further inform the user of the state information through the speaker power amplifier circuit 14.

[0034] In some embodiments, the input end of the module circuit 12 is electrically connected with the output end of the microphone circuit 13. The microphone circuit 13 is responsible for collecting the voice signals issued by the user, and when the user speaks towards the microphone, the microphone converts the mechanical wave of the sound into an electrical signal. The microphone circuit 13 transmits the collected electrical signal to the module circuit 12, and the input end of the module circuit 12 is electrically connected with the output end of the microphone circuit 13, so that the voice signal can be smoothly transmitted from the microphone circuit 13 to the module circuit 12. After receiving the voice signal from the microphone circuit 13, the module circuit 12 processes the signal, including amplifying and filtering the signal, so as to improve the quality of the signal; the module circuit 12 identifies the processed voice signal, and the module circuit 12 identifies the instruction content contained in the voice signal through the built-in algorithm and technology.

[0035] As an example, when the user says "turn on the air conditioner", the microphone circuit 13 converts the mechanical wave corresponding to this sound into an electrical signal. The module circuit 12 identifies the instruction "turn on the air conditioner" and then converts it into a corresponding electrical signal instruction, which is transmitted to the control circuit 10 through the communication circuit 11, and finally realizes the operation of turning on the air conditioner.

[0036] In some embodiments, the output end of the module circuit 12 is electrically connected to the input end of the speaker power amplifier circuit 14. The module circuit 12 is used to provide system prompts. The main function of the speaker power amplifier circuit 14 is to perform power amplification on the input audio signal. The voice signal output by the module circuit 12 is usually small in power and insufficient to drive the speaker to emit loud enough sound. By electrically connecting the output end of the module circuit 12 to the input end of the speaker power amplifier circuit 14, the audio signal is transmitted from the module circuit 12 to the speaker power amplifier circuit 14, which amplifies the signal so that the audio signal has sufficient power, thereby enabling the user to clearly hear the voice information of the system feedback, such as operation completion prompts, error information or other system-related notifications, etc.

[0037] As an example, when the system starts or encounters some special situations (such as connection abnormalities, signal errors, etc.), the module circuit 12 can generate corresponding voice prompt information, which is amplified by the connected speaker power amplifier circuit 14 and output from the speaker, providing real-time feedback of the system state to the user and enhancing the interactivity between the user and the system.

[0038] In some embodiments, the control circuit 10 includes a control chip (not shown in the figure), which is provided with a plurality of digital communication interfaces and a plurality of analog interfaces.

The No. 1 pin of the connector J4 is connected to the VDD_5V power supply end to provide working voltage for the connector J4. The No. 2 pin, No. 5 pin and No. 6 pin of the connector J4 are grounded. The communication circuit 11 sends the voice instructions or radio frequency remote control instructions issued by the module circuit 12 to the control circuit 10, which decodes the instructions after receiving them and converts them into control instructions, realizing voice control and radio frequency remote control of the air conditioner.

The No. 2 pin of the module chip U1 is connected with the VDD_5V power supply end through a series fixed resistor R1 to provide working voltage for the module chip U1.

Among them, the capacitor C8 is used for filtering and coupling. The No. 2 pin of the radio frequency antenna ANT1 is used for grounding. The module circuit 12 receives the radio frequency signal sent by the radio frequency remote controller through the radio frequency antenna ANT1, demodulates the radio frequency signal, identifies the remote controller instruction, and then sends it to the control circuit 10 through the communication circuit 11.

[0043] As an example, when the module chip U1 receives the radio frequency signal from the outside, the radio frequency signal may be relatively weak, and through the amplification of the operational amplifier Y1, the signal can be amplified to an amplitude suitable for subsequent circuit processing. When the module chip U1 needs to send data, the operational amplifier Y1 can amplify the signal to be sent so that it can be effectively sent out.

[0044] In some embodiments, as shown in Figure 4 The microphone circuit 13 includes a microphone J1 for receiving voice instructions sent by the user. The 2nd pin of the microphone J1 is connected to the 14th pin of the module chip U1 through a fixed resistor R3 and a capacitor C9 connected in series, to transmit the M IC P L signal; then the sound signal is converted into an electrical signal, and the converted electrical signal is processed by the resistor and the capacitor to remove noise and make necessary signal adjustment, and then transmitted to the module circuit 12 for processing. The 1st pin, the 3rd pin and the 4th pin of the microphone J1 are grounded.
