[0038] Reference Figure 7 , an embodiment of the present invention provides a microphone host control method, including steps S100 to S400.
[0039] Step S100: storing at least two sets of microphone data.
[0040] Specifically, the processor can store multiple groups of microphone data, which can be two groups, four groups, etc. Different microphone data correspond to different microphones. When it is necessary to switch to a different microphone, it is only necessary to switch to a different microphone data.
[0041] Step S200: receiving a key signal.
[0042] In some specific embodiments of the present invention, receiving a key signal includes triggering a key and receiving a signal generated when the key is triggered. Specifically, a single key may generate an electrical signal when triggered. For example, when the processor is outputting a first set of microphone data, i.e., the first microphone is being used, triggering the key is interpreted as a signal to switch to outputting a second set of microphone data, i.e., to switch to using the second microphone.
[0043] Step S300: Determine the key signal type.
[0044] In some specific embodiments of the present invention, determining the key signal type includes determining whether the key signal is a microphone data switching signal, and if so, searching for corresponding microphone data. A microphone host typically has multiple function keys. Therefore, when a key signal is received, the processor needs to determine whether the current key signal is a microphone data switching signal. If so, enter a search mode to search for microphone data corresponding to the signal.
[0045] Step S400: outputting corresponding microphone data according to the key signal type determination result.
[0046] In some specific embodiments of the present invention, the corresponding microphone data is output based on the key signal type judgment result, including: storing the first microphone data and the second microphone data; if the first microphone data is currently in use, stopping the output of the first microphone data and outputting the second microphone data. By receiving the signal of the microphone data switching key, the first microphone can be turned off and the second microphone can be enabled at the same time. Specifically, the microphone data includes frequency data and volume data. The frequency data and volume data of the microphone are stored in the processor. When switching to a different microphone for use, they can be used without re-adjustment, thereby improving the efficiency of microphone switching.
[0047] By receiving and judging the signal type of the button, the corresponding data output is selected from multiple pre-stored sets of microphone data. Therefore, there is no need to re-bind when switching microphones. The user data can be switched and output directly through button operation, effectively improving the switching efficiency of the microphone.
[0048] An embodiment of the present invention further provides a microphone host control circuit, comprising:
[0049] At least one set of data switching button modules, used for inputting microphone data switching signals;
[0050] The first processor U1 is configured to receive an input signal from the data switching button module and output corresponding microphone data.
[0051] The output end of the data switching button module is connected to the input end of the first processor U1.
[0052] By connecting the data switching button module to the first processor U1, upon receiving a signal from the data switching button module, the first processor U1 directly outputs the pre-stored corresponding microphone data, thereby switching between microphones and improving microphone switching efficiency. Specifically, a programming interface J3 is included, the output of which is connected to the input of the first processor U1. Data within the first processor U1 can be updated through programming interface J3.
[0053] In some specific embodiments of the present invention, an infrared frequency binding button module is further included. The infrared frequency binding button module includes a first button SW1 and a first resistor R1. One end of the first button SW1 is grounded, and the other end is connected to one end of the first resistor R1. The other end of the first resistor R1 is connected to a power supply via a second resistor R2 and is connected to the first button input terminal of the first processor U1.
[0054] The data switching button module includes a second button SW2 and a third resistor R3. One end of the second button SW2 is grounded, and the other end is connected to one end of the third resistor R3. The second button SW2 is connected to one end of the first button SW1 through the fourth resistor R4 and the first resistor R1. The other end of the third resistor R3 is grounded.
[0055] By connecting the infrared frequency binding key module and the data switching key module in series, the infrared frequency binding key module and the data switching key module can share a power supply, thereby reducing the use of circuit components and effectively saving costs.
[0056] In some specific embodiments of the present invention, at least one group of encoding modules is further included, and the encoding module includes an encoder. One end of the switch on the encoder is connected to the power supply through the second resistor R2, and the other end is grounded. The A port of the encoder is connected to the input port of the first processor U1 through the sixth resistor R6, and is connected to the power supply through the resistor R8; the B port of the encoder is connected to the input port of the first processor U1 through the seventh resistor R7, and is connected to the power supply through the ninth resistor R9.
[0057] Connecting the encoding module, infrared frequency binding key module and data switching key module in series allows one end of the encoding module to share the same power supply with the infrared frequency binding key module and the data switching key module, reducing the use of components and saving costs.
[0058] In some specific embodiments of the present invention, a second processor U2 is further included, configured to output an indicator light signal, and at least one set of indicator light modules, each comprising a light-emitting diode D1D1. One end of the light-emitting diode D1D1 is connected to a power source via a fifth resistor R5, and the other end is connected to an output terminal of the second processor U2. For example, multiple sets of indicator light modules may be provided so that when the data switching button module switches between different microphone data outputs, the corresponding indicator light illuminates, while the indicator light corresponding to the deactivated microphone data turns off, making it easy to identify which microphone is in use.
[0059] Some specific embodiments of the present invention further include an infrared emission module comprising a transistor Q1. The collector of the transistor Q1 is connected to a power supply via a series-connected light-emitting diode D2 and a thirteenth resistor R13. The emitter of the transistor Q1 is connected to ground. The base of the transistor Q1 is connected to the first processor U1 via a twelfth resistor R12. Functional signals of the microphone host are output via the infrared emission module.
[0060] In some specific embodiments of the present invention, a first connector J1 and a second connector J2 are further included. The corresponding interfaces of the first connector J1 are respectively connected to the infrared frequency binding key module, the data switching key module, the encoding module, and the second processor U2. The interfaces of the second connector J2 are respectively connected to the corresponding interfaces of the first processor U1. The first connector J1 and the second connector J2 are connected. By using the first connector J1 and the second connector J2 to connect the various functional modules, circuit wiring can be simplified and the overall integration of the circuit can be improved.
[0061] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
