Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a receiver in an audio-visual device in a hardware operating environment according to an embodiment of the present invention.

As shown in fig. 1, the receiver in the audio/video device may include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a bluetooth interface 1003, a radio frequency interface 1004, and a memory 1005. Wherein a communication bus 1002 is used to enable connections between these components. The bluetooth interface 1003 can be connected with an upper computer or a wireless microphone. The radio interface 1004 may alternatively be a Wireless radio interface (e.g., a Wireless-Fidelity (WI-FI) interface). The Memory 1005 may be a Random Access Memory (RAM) or a Non-volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001. The wireless microphone in the av device may include a radio frequency module and a bluetooth module, and the receiver may include a radio frequency module, a bluetooth module, and a main processor chip, which may be the processor 1001. In addition, audio-visual equipment can also set up the connection pilot lamp, when the receiver is accomplished with wireless microphone to frequently, can show current connection status through the pilot lamp.

Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the receiver in an audiovisual device, and may include more or fewer components than shown, or some components in combination, or a different arrangement of components.

As shown in fig. 1, memory 1005, identified as one type of computer storage medium, may include an operating system, a radio frequency communication module, a bluetooth interface module, and a microphone and receiver connection program.

Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a method for connecting a microphone and a receiver according to the present invention.

In a first embodiment, the microphone and receiver connection method includes the steps of:

step S10: the receiver sends a heartbeat broadcast.

It should be understood that in an embodiment, the K device includes a receiver and a number of wireless microphones. The receiver can be used for receiving the audio signals collected by the wireless microphone and the music signals output by the upper computer equipment. Wherein, all include bluetooth module and radio frequency module in receiver and the wireless microphone. The Bluetooth module can be used for transmitting the music signals in a Bluetooth mode. The upper computer can send the music signal to the radio frequency module through the bluetooth module, and then the radio frequency module can also send the music signal to the wireless microphone through the bluetooth module. The radio frequency module can be used for transmitting the audio signals of the human voice collected by the wireless microphone. For example, the wireless microphone may send the collected voice to the receiver through the radio frequency module, or may send the voice to other wireless microphones within the synchronous working frequency point. The respective wireless microphones may be connected by a receiver. When the double-microphone K sings, the two microphones can be arranged at the same working frequency point through the same receiver, and then the transmission of human sound signals and music signals is carried out to realize the double-microphone K sings. Of course, for example, the receiver sends the music signal to two wireless microphones at the same time, or the receiver sends the music signal to one microphone, which can send the music signal and the human voice signal to the other microphone at the same time through the radio frequency module.

It should be noted that the heartbeat broadcast is a flooding information transmission method, and information in the heartbeat broadcast can be transmitted to all wireless microphones.

In the process of connecting the wireless microphone and the receiver, the receiver can send the current state information in a certain range in a flooding mode, and all the wireless microphones in the range can receive heartbeat broadcasts sent by the receiver.

Step S20: and when the wireless microphone receives the heartbeat broadcast, feeding back an access request to the receiver.

In the device connection process, one of the devices is required to output an access request, and the other device is required to connect the two devices when receiving the access request. Wherein the access request is a request output by the wireless microphone for establishing a connection with the receiver. The access request may include wireless microphone device parameter information, such as Identification (ID) information of the wireless microphone, version number of software and hardware, device model, and the like.

When the wireless microphone and the receiver need to establish connection, the wireless microphone in the receiver heartbeat broadcast flooding range can extract the own device parameter information when receiving heartbeat broadcasts, then generates an access request according to the extracted device parameter information, and feeds the access request back to the receiver.

Step S30: and when the receiver receives the access request, selecting a synchronous working frequency point and sending the synchronous working frequency point to the wireless microphone.

It should be understood that the receiver can simultaneously receive the human voice signals collected by the plurality of wireless microphones. For different voice signals, the receiver can receive different voice signals collected by different microphones through different working frequency points connected with the microphones. And for the wireless microphones with the same working frequency point, the voice signals can be simultaneously sent to the receiver, so that the voice signals simultaneously acquired by the multiple microphones can be received. The synchronous working frequency point refers to a frequency point used for data transmission between the receiver and the wireless microphone. A receiver can comprise a plurality of working frequency points, and each frequency point can be connected with one or more wireless microphones.

In specific implementation, when receiving an access request fed back by a wireless microphone, a receiver can identify the wireless microphone according to the access request, then select a frequency point from the spare frequency points as a synchronous working frequency point of the wireless microphone and the receiver, and feed back an address of the access request to the wireless receiver to generate the synchronous working frequency point, so as to send the synchronous working frequency point to the wireless microphone.

Step S40: and the wireless microphone adjusts the working frequency point to the synchronous working frequency point.

It should be understood that, when the wireless microphone receives the synchronous working frequency point fed back by the receiver, it can be shown that the wireless microphone can be accessed to the receiver, and the wireless microphone can adjust the working frequency point to the synchronous working frequency point output by the receiver, so as to establish connection with the receiver.

Step S50: and the receiver adjusts the current working frequency point to the synchronous working frequency point to establish connection with the wireless microphone.

It should be noted that, after determining the synchronous working frequency point, the receiver needs to send the synchronous working frequency point to the wireless microphone, and also needs to adjust its current working frequency point to the synchronous working frequency point. The receiver can adjust the working frequency point and the sending process of the synchronous working frequency point in sequence in part of time. The receiver can firstly send the synchronous working frequency point to the wireless microphone, and then adjust the current working frequency point of the receiver to the synchronous frequency point; or the current working frequency point of the microphone can be adjusted to the synchronous working frequency point, and then the synchronous working frequency point is sent to the wireless microphone. Under the condition of considering the connection time, the receiver can firstly send the synchronous working frequency points to the wireless microphone, and then the receiver and the wireless microphone simultaneously adjust the respective working frequency points to the corresponding synchronous working frequency points, so that the efficiency of establishing connection is improved.

It should be noted that the wireless microphone can be connected to the receiver only at one working frequency point, and generally, the wireless receiver only works at one working frequency point. The receiver may need to be connected to multiple wireless microphones and therefore the receiver may operate at multiple operating frequencies. The current working frequency point refers to a working frequency point corresponding to the receiver at the current time point.

In a first embodiment, there is provided a microphone and receiver connection method for transmitting a heartbeat broadcast by the receiver; when the wireless microphone receives the heartbeat broadcast, feeding back an access request to the receiver; when the receiver receives the access request, a synchronous working frequency point is selected and sent to the wireless microphone; the wireless microphone adjusts the working frequency point to the synchronous working frequency point; and the receiver adjusts the current working frequency point to the synchronous working frequency point to establish connection with the wireless microphone. In this embodiment, when receiving an access request, the receiver selects a synchronous working frequency point, and then the receiver and the wireless microphone both adjust the working frequency point to the synchronous working frequency point to establish connection, thereby avoiding manual frequency alignment and realizing more convenient connection of the wireless microphone and the receiver.

Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a method for connecting a microphone and a receiver according to the present invention, and the second embodiment of the method for connecting a microphone and a receiver according to the present invention is proposed based on the first embodiment shown in fig. 2.

In the second embodiment, the step S10 includes:

step S101: the receiver detects microphone access status information.

It should be understood that the receiver output heartbeat broadcast should include the current microphone access status information of the receiver to avoid receiving the access request fed back by the wireless microphone in case the receiver cannot continue to connect the microphone. For example, one receiver may be connected with eight wireless microphones, and at this time, the receiver has already connected with eight wireless microphones, and when sending a heartbeat broadcast, the receiver may send a current state of accessing the eight microphones, and the wireless microphone may determine whether to feed back an access request according to current microphone access state information in the heartbeat broadcast.

It should be noted that the microphone accessing state information may include information on the number of currently accessed microphones and information on the number of currently accessible microphones. Of course, the microphone access status information may also include only the information of the number of currently accessible microphones or include the information of the total port number and the information of the number of currently accessed microphones, which can reflect whether the receiver can currently access the wireless microphone.

In a specific implementation, the receiver may detect microphone access state information, such as information about the number of microphones that the receiver has accessed and information about the number of accessible microphones. For example, the receiver may output a heartbeat signal to each node for connecting the wireless microphone, and determine the current microphone access state information according to the feedback condition of each node. Certainly, in the detection process, the current time point can be detected independently, and the number information of the wireless microphones can be accessed; it is also possible to separately detect information on the number of wireless microphones that have been accessed at the current point in time and then determine information on the number of connectable wireless microphones based on device parameters of the receiver.

Step S102: and the receiver generates heartbeat broadcast according to the microphone access state information.

It should be understood that the heartbeat broadcast has a certain data transmission protocol, and the data packets within the heartbeat broadcast also need a certain format. For example, the format of the data packet in the heartbeat broadcast may be a format including a packet header, a heartbeat count, the number of accessible microphones, the number of accessed microphones, an ID of the accessed microphones, a packet end check, and the like.

In the generation process of the heartbeat broadcast, the receiver can select the transmission format of the data packet, and then the receiver combines the detected microphone access state information according to the transmission format of the data packet to generate the corresponding heartbeat broadcast; of course, the format template corresponding to the transmission format may also be extracted, and then the microphone access status information is sequentially filled into the format template to obtain the heartbeat broadcast.

Step S103: and the receiver sends the heartbeat broadcast according to a set frequency.

It should be noted that, during the process of sending the heartbeat broadcast, the receiver may have a process of switching on or off the wireless microphone, and at this time, information of a data packet in the heartbeat broadcast of the receiver needs to be adjusted, or microphone access information needs to be detected again. The frequency of the heartbeat broadcast transmitted by the receiver is a frequency corresponding to an interval time of adjacent heartbeat broadcast transmission. The receiver may complete the adjustment or regeneration of the heartbeat broadcast during this time period. Under the condition of overlarge sending frequency of heartbeat broadcasting, the wireless microphone can be accessed timely, so that the time consumption of the access process of the wireless microphone is long, and the connection efficiency is low. In this embodiment, the receiver may first select a transmission frequency of the heartbeat broadcast, for example, a frequency of transmitting the heartbeat broadcast once in two seconds, and then transmit the heartbeat broadcast according to the selected frequency.

The step S20 includes:

step S201: the wireless microphone determines whether the receiver is in a connectable state according to the microphone access state information.

It should be understood that the current state of the receiver may include a connectable state and a non-connectable state. Each port in the receiver is connected with a wireless microphone, and no idle port exists, so that the receiver can be determined to be in a non-connectable state; and a receiver can be considered to be in a connectable state when a free port exists in the receiver. When the wireless microphone receives the heartbeat broadcast, whether the receiver is in a connectable state can be determined according to the microphone access state information in the heartbeat broadcast.

In a specific implementation, when the wireless microphone receives the heartbeat broadcast, the wireless microphone may parse a data packet in the heartbeat broadcast, determine the number information of the accessible microphones in the data packet, and when the number information of the accessible microphones is not zero, may determine that the receiver is in a connectable state.

Step S202: the wireless microphone feeds back an access request to the receiver when the receiver is in a connectable state.

It should be understood that the connectable state is a state defining a receiver, and the receiver includes a connectable state and a non-connectable state. When the receiver is determined to be in a connectable state, the wireless microphone can generate a corresponding access request according to the device parameter information such as the ID, the hardware version, the software version and the product model of the wireless microphone, and then the access request is fed back to the receiver according to the address of the heartbeat broadcast sent by the receiver. The data packet in the feedback request should be fed back according to a certain data format, including, for example, a header, a trailer check, and intermediate device parameter information.

The step S30 includes:

step S301: and when receiving an access request fed back by a wireless microphone according to the heartbeat broadcast, the receiver analyzes the access request and acquires the equipment parameter information of the wireless microphone.

It is understood that there may be abnormal situations such as mismatch, incompatibility between the receiver and the wireless microphone, in which case audio data transmission may not be possible between the receiver and the wireless microphone, and there is no meaning in connecting an incompatible wireless receiver to the receiver.

Therefore, when the receiver receives the access request sent by the wireless microphone, the receiver can also analyze the access request, and extract the device parameter information such as the device ID, the hardware version, the software version, the product model and the like of the wireless microphone in the data packet in the access request.

Step S302: and the receiver judges whether the wireless microphone is in an accessible state according to the equipment parameter information.

In this embodiment, the receiver may determine the compatibility and matching degree between the wireless microphone and the receiver according to the device parameter information provided by the wireless microphone. In specific implementation, the receiver may compare the product model of the wireless microphone sending the access request with a product signal set of a wireless microphone that can be normally connected to the receiver, and when the product model of the wireless microphone sending the access request is in the product signal set of the wireless microphone that can be normally connected to the receiver, the receiver determines that the wireless microphone can be matched with the receiver. Of course, the software version of the wireless microphone may be matched with the software version that can be supported by the receiver, and if the matching is successful, the wireless microphone and the receiver may be determined to be connected for data transmission.

Step S303: and the receiver detects the signal quality of the vacant frequency point when the wireless microphone is in an accessible state.

It should be understood that the accessible state is a state that defines the wireless microphone. The spare frequency point refers to a frequency point which is not connected with other wireless microphones in the receiver at the current time point. There may be multiple spare frequency points in the receiver, and the signal quality of the transmitted signals in each spare frequency point is different. Signal quality refers to the accuracy of the transmitted signal during transmission of the signal. The better the signal quality, the more accurate the transmitted signal symbols, the more accurate the information obtained. When the receiver determines that the wireless microphone sending the access request can be connected, the receiver can also detect the signal quality of the rest of the vacant frequency points, for example, signals of a certain number of code elements are transmitted through all the vacant frequency points, and the signal quality is determined according to the accuracy of the received code elements.

Step S304: and the receiver selects the spare frequency point with the best signal quality as a synchronous working frequency point and sends the synchronous working frequency point to the wireless microphone.

In this embodiment, in the process of selecting the synchronous working frequency point, selecting the vacant frequency point with general signal quality as the synchronous working frequency point may result in that the accuracy of the audio signal transmitted by using the synchronous working frequency point is reduced, and the vacant frequency point with the best idle signal quality is not effectively utilized. Therefore, in the implementation, the receiver can select the spare frequency point with the best signal quality as the synchronous working frequency point, so that the accuracy of the audio signal is improved.

In the second embodiment, the invalid connection can be effectively avoided through mutual confirmation between the wireless microphone and the receiver, so that the efficiency of establishing the connection between the microphone and the receiver is further improved. In addition, the receiver selects the spare frequency points through selection, and the spare frequency points with the best signal quality are used as synchronous working frequency points, so that the accuracy of audio signals can be improved.

Referring to fig. 4, fig. 4 is a flowchart illustrating a method for connecting a microphone and a receiver according to a third embodiment of the present invention, and the third embodiment of the method for connecting a microphone and a receiver according to the present invention is proposed based on the first embodiment or the second embodiment.

In the third embodiment, after the step S50, the method further includes:

step S51: and the receiver receives the upper layer interactive message output by the upper computer.

It should be understood that in audio-visual equipment, the receiver is also connected to equipment associated with the host computer. The upper computer can be a computer, a server and other equipment. The upper computer can provide a song requesting platform for a user, output song audio and the like. The upper computer can establish connection with each wireless microphone through the receiver and control the wireless microphones. For example, the display unit on the wireless microphone is controlled to display the interactive information, the status information and the like. In this embodiment, the wireless microphone may include a display unit for displaying information to be displayed, such as currently used frequency point, power, microphone ID, name of song currently played, and next song. Wherein, the display unit may be an oled display screen.

It should be noted that the upper layer interactive message is output by the upper computer, and is used for controlling the wireless microphone and the message for interacting, such as the interactive message showing the name of the accompaniment, the song, the score of the karaoke song, and the like.

Step S52: and the receiver generates an interaction instruction by using a preset interaction protocol according to the upper layer interaction message and outputs the interaction instruction to the wireless microphone.

It should be noted that the interaction instruction is an instruction generated by the controller to control the wireless microphone to interact with the user information. The preset interactive protocol is a protocol preset for transmitting interactive messages. The predetermined interactive protocol may be a protocol including a header, interactive information, and a trailer verification, such as a protocol including a header, an accompaniment name, a melody, a karaoke score, and a trailer verification format.

In specific implementation, when the receiver receives an upper layer interactive message output by an upper computer, the receiver can adjust the upper layer interactive message according to a preset interactive protocol to generate an interactive instruction, and then the interactive instruction is sent to the wireless microphone.

Step S53: and the wireless microphone displays the upper layer interactive message through a display unit.

It can be understood that, when the wireless microphone receives the interaction instruction, the wireless microphone may analyze or demodulate the interaction instruction to extract the upper layer interaction message in the interaction instruction, and then display the upper layer interaction message through the display unit. For example, the host computer needs the wireless microphone to show that current K song is scored and the user is interactive, and the host computer can output specific K song to the receiver. The receiver adjusts the score of the K song according to a preset interaction protocol to obtain an interaction instruction for displaying the score of the K song, the interaction instruction is sent to the corresponding wireless microphone, when the wireless microphone receives the interaction instruction, the interaction instruction is analyzed by using the preset interaction protocol to obtain the current score of the K song, and then the specific score of the K song is displayed through the display unit. The wireless microphone can display score values and color interaction on the oled screen according to the score of the k songs transmitted by the receiver, the wireless microphone can display the scores and the color interaction on the oled screen according to the accompaniment names transmitted by the receiver, and the wireless microphone can synchronously display colors and names on the oled screen according to the songs transmitted by the receiver.

Step S54: the receiver outputs a detection instruction to the wireless microphone.

In addition, in this embodiment, the receiver may further output a detection instruction to the wireless microphone. The detection instruction is an instruction for controlling the wireless microphone to detect the state of the wireless microphone. The detection instruction may be to detect device parameters such as the remaining power of the wireless microphone and the brightness of the display unit, or may be to detect the current operating state of the wireless microphone, for example, to acquire a human voice state, and to perform an interaction state with another wireless microphone.

Step S55: and when the wireless microphone receives the detection instruction or reaches the preset self-detection time, self-detecting the current state information and feeding back the current state information to the receiver.

In this embodiment, the receiver may directly output the detection instruction to the wireless microphone, and the wireless microphone may perform the self-detection at a certain preset self-detection time interval. The preset self-checking time is the interval time preset for the wireless microphone to detect the self state. The preset self-checking time can be 2 to 5 seconds, and certainly, when a detection instruction is received, self-checking should be started immediately and current state information should be fed back.

In specific implementation, the wireless microphone may start the self-test once every a preset self-test time, respectively detect the remaining power of the wireless microphone, the brightness of the display unit, the current working state, and the like to obtain current state information, and then feed the current state information back to the receiver.

Referring to fig. 5, fig. 5 is a flowchart illustrating a method for connecting a microphone and a receiver according to a fourth embodiment of the invention. Based on any one of the first to third embodiments, a fourth embodiment of the method for connecting a microphone and a receiver according to the present invention is provided.

In this embodiment, the wireless microphone may further detect a connection state between the wireless microphone and the receiver, so as to avoid disconnection between the wireless microphone and the receiver and incapability of data transmission. After step S50, the step of detecting the connection state by the wireless microphone specifically includes:

step S501: the wireless microphone continues to receive heartbeat broadcasts output by the receiver after establishing a connection with the receiver.

It should be understood that information on the number of currently accessed microphones and corresponding ID information may be included in the heartbeat broadcast transmitted by the receiver. After the wireless microphone establishes connection with the receiver, the wireless microphone can also continuously receive heartbeat broadcast output by the receiver, and then the ID information of the accessed microphone in the heartbeat broadcast is acquired. In a specific implementation, the bluetooth module of the wireless microphone may continue to receive the heartbeat broadcast output by the receiver after establishing a connection with the receiver.

Step S502: and the wireless microphone judges whether the wireless microphone is in an off-line state according to the accessed microphone information in the heartbeat broadcast.

It should be noted that the connection state of the wireless microphone includes an online state and an offline state. The online state refers to a state in which the wireless microphone and the receiver are currently connected, and the offline state refers to a state in which the wireless microphone and the receiver are currently disconnected.

In this embodiment, the wireless microphone may determine whether the accessed microphone information in the received heartbeat broadcast includes unique identification information of the wireless microphone, for example, whether the accessed microphone ID includes an ID of the wireless microphone, and determine whether the current microphone itself is in an offline transition state. The unique identification information refers to identification information that the wireless microphone has distinction from other wireless microphones. The unique identification information corresponding to different wireless microphones is different. The unique identification information may be a hardware serial number, ID, etc. of the device. When the current accessed microphone information does not include the unique identification information of the current accessed microphone information, the current wireless microphone can be determined to be in an offline state.

Step S503: and when the wireless microphone is in an offline state, the wireless microphone retransmits the access request to the receiver.

When the wireless microphone is confirmed to be in an off-line state, the wireless microphone can resend the access request to the receiver, and when the receiver receives the corresponding access request again, the synchronous working frequency point can be chosen again and fed back, so that the wireless microphone and the receiver are connected again.

In the third embodiment, the receiver can enable the wireless microphone to display the upper layer interactive message and interact with the user, so that the user experience is further improved. In addition, the method can also continuously receive heartbeat broadcasting, judge the connection state of the wireless microphone, and establish connection with the receiver again when the wireless microphone is in an off-line state.

In this embodiment, after step S50, the method further includes:

It should be understood that different wireless microphones may be connected through a receiver, and then two wireless microphones operating at a synchronous operating frequency implement a dual-microphone karaoke. In the process of singing with the double microphones, the two wireless microphones are required to transmit audio data through respective internal radio frequency modules. In the audio data transmission process, the electric quantity consumption of the wireless microphone can be increased, so that in the double-microphone K song process, when one wireless microphone is disconnected, the other wireless microphone can actively close the radio frequency module, and the electric quantity consumption caused by the radio frequency module is reduced. The wireless microphone is connected with the receiver through the internal Bluetooth module.

It should be noted that the first wireless microphone and the second wireless microphone are only used for distinguishing the wireless microphones of the two dual-microphone karaoke, and the wireless microphones are not limited otherwise. The preset heartbeat time is a preset heartbeat time. The preset heartbeat time can be the maximum time of generating heartbeat by a normal heartbeat mechanism, and other times can be selected, so that the preset heartbeat time is longer than the maximum time of generating heartbeat by the normal heartbeat mechanism.

In specific implementation, because a heartbeat detection mechanism exists between the wireless microphones at the synchronous working frequency point, the first wireless microphone can continuously monitor the heartbeat information of the second wireless microphone, when the time of not detecting the heartbeat information is greater than the preset heartbeat time, the connection between the second wireless microphone and the first wireless microphone can be determined to be disconnected, and the first wireless microphone can close the radio frequency module in the first wireless microphone, so that the electric quantity consumption of the wireless microphones is reduced.

Furthermore, an embodiment of the present invention further provides a storage medium, where a microphone and receiver connection program is stored, and the microphone and receiver connection program, when executed by a processor, implements the steps of the microphone and receiver connection method as described above.
