[0030] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0032] It should be noted that the terms "set," "install," and "connect" in the embodiments of the present invention should be interpreted broadly. Those skilled in the art can reasonably determine the specific meanings of these terms in the embodiments of the present invention based on the specific content of the technical solution. For example, the term "connect" can refer to mechanical connection, electrical connection, or communication; it can refer to direct connection or indirect connection through an intermediary.
[0033] It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0034] Currently, diversity reception technology is used to achieve better signal transmission. This involves installing multiple antennas on a receiver to receive radio wave signals from a single microphone. The antennas are then switched based on the quality of the received audio signal, ensuring the receiver outputs a higher quality audio signal. However, in actual use, it's difficult for users to understand the receiver's signal reception status while using the microphone, and even more difficult to make adjustments based on this information, such as changing the channel, adjusting the operating distance, or adjusting the receiver antenna angle.
[0035] Based on this, an embodiment of the present invention proposes a wireless audio receiving system, in which the wireless audio receiver and signal indicator in the wireless audio receiving system are separately arranged, and the signal indicator and the audio switching circuit of the wireless audio receiver are communicatively connected, which means that the signal indicator and the wireless audio receiver can be installed in different positions according to the actual needs of the user. At the same time, the signal indicator can remotely display in real time which signal receiving circuit the audio switching circuit is currently using to receive the audio signal, so that the user can intuitively understand the signal reception status of the wireless audio receiver, that is, which signal receiving circuit receives the audio signal with better signal quality, thereby helping the user to make timely adjustments during the use of the microphone to optimize the signal transmission effect.
[0036] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings.
[0037] Reference Figure 1 , Figure 1is a schematic diagram of the structure of a wireless audio receiving system provided by an embodiment of the present invention. It is understood that the wireless audio receiving system includes a detachable wireless audio receiver 100. Specifically, the wireless audio receiver 100 includes multiple signal receiving circuits, each of which corresponds to a receiving antenna 110. The signal receiving circuit can receive radio wave signals transmitted by a wireless microphone via the receiving antenna 110. The multiple receiving antennas 110 are disposed at different locations on the wireless audio receiver 100, thereby receiving audio signals transmitted by the same wireless microphone from different directions. In other words, the signal quality of the audio signals received by different signal receiving circuits varies. In particular, in complex environments (such as large-scale events or environments with multiple obstacles), the signal quality of the audio signals received by different signal receiving circuits can vary significantly. Consequently, an audio switching circuit can select an appropriate signal receiving circuit (i.e., receiving antenna 110) to receive the radio wave signals transmitted by the wireless microphone based on the signal quality of the audio signals received by each signal receiving circuit, thereby achieving diversity reception of the audio signal.
[0038] The signal indicator 200 is provided separately from the wireless audio receiver 100. This means that the wireless audio receiver 100 and the signal indicator 200 do not need to restrict each other's installation positions and can be installed in different locations according to actual needs, providing greater installation flexibility. For example, the signal indicator 200 can be placed in a position that is convenient for the user to observe according to actual usage requirements, such as the signal indicator 200 can be placed on the side of the stage, while the wireless audio receiver 100 is installed in the stage control room. In addition, the signal indicator 200 is connected to the audio switching circuit in the wireless audio receiver 100 by communication. The signal indicator 200 and the signal detection circuit can be connected by wired or wireless communication. Therefore, the signal reception status of which signal receiving circuit the audio switching circuit uses to receive the audio signal can be transmitted to the signal indicator 200 in real time. The signal indicator 200 can display the mark corresponding to the signal receiving circuit receiving the current audio signal in real time through a visual means (such as an LED light bar, light strip, digital display, etc.). Each signal receiving circuit has a one-to-one correspondence with its corresponding mark, that is, each different mark can represent a different signal receiving circuit. Therefore, through the mark displayed by the signal indicator, it can be understood which signal receiving circuit the current audio switching circuit uses to receive the audio signal, and it can also reflect which signal receiving circuit receives the audio signal with better signal quality, so that the user can intuitively understand the signal reception situation of the wireless receiver; and when the audio switching circuit switches to different signal receiving circuits to receive the audio signal, the signal indicator will also synchronously update the mark of the corresponding signal receiving circuit. The real-time feedback mechanism enables the user to quickly respond to changes in signal quality and then make corresponding adjustments to optimize the signal transmission effect, such as switching to change the use distance of the wireless microphone, changing the angle of the receiver antenna, and other measures.
[0039] In summary, in the wireless audio receiving system proposed in the embodiment of the present invention, by separating the signal indicator 200 from the wireless audio receiver 100, and the signal indicator 200 and the audio switching circuit in the wireless audio receiver 100 are communicatively connected, the signal indicator 200 and the wireless audio receiver 100 can be installed in different positions according to actual usage requirements, and the signal indicator 200 can remotely display the signal reception status of the wireless audio receiver 100 in real time through the signal indicator 200, which is convenient for the user to understand intuitively, thereby helping the user to make timely adjustments during the use of the wireless microphone to optimize the signal transmission effect.
[0040] In the related art, some wireless audio receivers 100 that employ diversity reception do not include a module that indicates the diversity operation status or signal quality. This prevents users from directly observing the signal reception status of the wireless audio receiver 100 and making timely adjustments. Alternatively, although some wireless audio receivers 100 include a display module for indicating signal quality, the display module is integrated into the wireless audio receiver 100. However, since the wireless microphone is used at a long distance (e.g., several meters or even tens of meters from the wireless audio receiver 100), it is difficult for users to directly observe the display module on the distant wireless audio receiver 100 while using the wireless microphone, making it difficult for users to make timely adjustments based on the signal reception status. Therefore, the wireless audio receiver 100 is typically placed relatively close to the wireless microphone, that is, within a range where the user can clearly observe the signal reception status of the wireless audio receiver 100 while using the wireless microphone. This limits the usable range of the wireless audio receiver 100 and the wireless microphone. The wireless audio receiving system provided in the embodiment of the present invention has high installation flexibility, avoids the wireless microphone, wireless audio receiver 100 and signal indicator 200 from mutually restricting the scope of use, and can be applied to different locations according to actual needs. At the same time, it can facilitate users to remotely understand the signal reception status of the receiver in real time, which helps users to make timely adjustments when using the microphone.
[0041] Reference Figure 2 , Figure 2 This is an optional schematic diagram of an application scenario of the wireless audio receiving system provided by an embodiment of the present invention. It should be noted that the wireless audio receiver 100 can also be integrated into an audio device, such as an integrated audio device, and the separate signal indicator 200 can also be used in conjunction with the integrated audio device integrated with the wireless audio receiver 100. Similarly, the signal indicator 200 is communicatively connected to the audio switching circuit of the wireless audio receiver 100 in the integrated audio device to display the signal reception status of the integrated audio device.
[0042] It is understood that the wireless audio receiver 100 also includes an audio switching switch and an audio processing circuit. The audio processing circuit is used to process the original audio signal received by the signal receiving circuit and then input it into the post-processing circuit in the wireless audio receiver 100 for playback. The audio processing circuit may include an audio amplifier circuit, a frequency discrimination circuit, and a filter circuit. The audio switching switch can be used to switch and select the signal receiving circuit, that is, to select the audio signal received by the corresponding signal receiving circuit to be input into the audio processing circuit for processing and playback. For example, the wireless audio receiver 100 is provided with three signal receiving circuits, namely, a first signal receiving circuit corresponding to antenna one, a second receiving circuit corresponding to antenna two, and a third signal receiving circuit corresponding to antenna three. Antenna one, antenna two, and antenna three can all receive radio wave signals emitted by the same wireless microphone and convert the radio wave signals into audio signals through the corresponding signal receiving circuits. The audio switching switch can switch and select among the signal receiving circuits corresponding to antenna one, antenna two, and antenna three. If the audio switching switch switches to antenna one, it means that the wireless audio receiver 100 selects antenna one. The audio signal collected by the first signal receiving circuit corresponding to line one is input into the audio processing circuit for processing and playback, while the audio signals collected by the signal receiving circuits corresponding to antenna two and antenna three may not be processed, or may be input into the audio processing circuit for processing and not played. Therefore, the signal indicator 200 can also be connected to the audio switching switch, so that the signal indicator 200 can display the mark corresponding to the signal receiving circuit currently selected by the wireless audio receiver 100 to receive the current audio signal. The mark reflects the currently operating signal receiving circuit, so that the user can more intuitively understand the diversity operation of the wireless audio receiver 100 and adjust the use of the wireless microphone in time. For example, when using the wireless microphone, move closer to antenna one or adjust the direction of antenna one.
[0043] It is understood that the audio switching switch in the audio switching circuit selects a signal receiving circuit based on the signal quality of the audio signals received by each signal receiving circuit to ensure the signal quality of the audio signal output by the subsequent stage. In other words, the audio switching circuit can detect the signal quality of the audio signal received by the signal receiving circuit. Specifically, the audio switching circuit can include a signal detection circuit that can measure the signal quality of the input audio signal. The output terminals of all signal receiving circuits are connected to the input terminal of the signal detection circuit, so that the signal detection circuit can measure the signal quality of the audio signal received by each signal receiving circuit. At the same time, the output terminal of the signal detection circuit is also connected to the audio switching switch and the signal indicator, respectively. Furthermore, the audio switching switch can switch and select the signal receiving circuit to receive the audio signal based on the signal quality of the audio signal received by each signal receiving circuit output by the signal detection circuit. The signal indicator can also display the mark corresponding to the signal receiving circuit currently receiving the audio signal and the signal quality of the current audio signal. In addition, the signal indicator can also simultaneously display the signal quality of the audio signals received by all signal receiving circuits.
[0044] It should be noted that when the wireless audio receiver 100 adopts a diversity receiving mode to receive the audio signal of the wireless microphone, a high-amplitude diversity receiving mode and a medium-amplitude diversity receiving mode can be adopted. Figure 3 , Figure 3 This is an optional circuit structure diagram of the wireless audio receiver 100 provided in the embodiment of the present utility model. Figure 3In the high-frequency diversity reception mode, which can be referred to as an antenna diversity reception mode, the wireless audio receiver 100 is provided with multiple signal receiving circuits, each of which corresponds to a receiving antenna 110 and receives signals from a wireless microphone. The wireless audio receiver 100 also includes a signal detection circuit, an audio processing circuit, and an audio switching switch connected to each signal receiving circuit. The signal detection circuit detects the signal quality of the audio signal received by each signal receiving circuit. When the signal quality does not meet the required audio signal quality, another receiving antenna 110, i.e., another signal receiving circuit, is switched to receive the audio signal, in the hope that the audio signal received by the other signal receiving circuit has sufficient signal quality, thereby reducing the frequency drop and sound interruption caused by insufficient signal quality. That is to say, all signal receiving circuits are connected to the same audio processing circuit through the audio switching switch, and all signal receiving circuits are connected to the signal detection circuit. The signal detection circuit can detect the signal quality of the audio signals received by all signal receiving antenna circuits. The signal detection circuit can be connected to the audio switching switch, so that the audio switching switch can switch to select the signal receiving circuit with the highest signal quality of the audio signal, and the signal receiving circuit is connected to the audio processing circuit, that is, the signal receiving circuit is switched and selected through the audio switching switch, so that the audio processing circuit performs audio processing on the audio signal with the highest signal quality.
[0045] It should be noted that the signal detection circuit and the audio switching switch can be connected to the control chip, and the control chip adjusts the audio switching switch to select the signal receiving circuit with the highest signal quality based on the signal quality of each receiving antenna 110 detected by the signal detection circuit. It is worth noting that the operating principle of the control chip, that is, the operating principle of the audio switching switch to select the signal receiving circuit based on the signal quality of the audio signal received by each signal receiving circuit is the same as the operating principle of the audio receiver using diversity reception in the related art, which will not be elaborated here. The present utility model does not involve improvements to the logical principle of the switching signal input of the audio switching switch in the audio receiver. The present utility model only improves the circuit connection relationship of the audio switching switch.
[0046] In addition, refer to Figure 4 , Figure 4 This is an optional circuit structure diagram of the wireless audio receiver 100 provided in the embodiment of the present utility model. Figure 4In the context of amplified diversity reception, which can be referred to as true diversity reception, the wireless audio receiver 100 is provided with multiple signal receiving circuits for receiving signals from a single wireless microphone. The wireless audio receiver 100 is provided with a signal detection circuit, multiple audio processing circuits, and a corresponding audio switching switch. The number of audio processing circuits corresponds to the number of signal receiving circuits, and each signal receiving circuit is connected to each audio processing circuit in a one-to-one correspondence. After receiving an audio signal from the same wireless microphone, each signal receiving circuit inputs the signal to the corresponding audio processing circuit for processing. Each audio processing circuit is connected to both the signal detection circuit and the audio switching switch. The signal detection circuit detects the signal quality of each processed audio signal. By comparing the signal quality of the processed audio signals, the audio switching switch selects the audio processing circuit with the higher signal quality. In other words, the audio signal with the higher signal quality is used for subsequent processing. The audio processing circuits can be the same or different. For example, different audio circuits can process different specific frequency bands of the audio signal. Therefore, while the audio switching switch selects the signal receiving circuit currently receiving the audio signal, the audio processing circuit can also be switched. Thus, the signal indicator can simultaneously display the mark corresponding to the audio processing circuit currently processing the audio signal, prompting the user to the currently operating audio processing circuit, facilitating the user to adjust the currently operating audio processing circuit and signal receiving circuit. Furthermore, because the audio switching circuit also includes a signal detection circuit, the signal indicator can be communicatively connected to the signal detection circuit, allowing the signal indicator to display the signal quality of the current audio signal after audio processing, as well as the signal quality of audio signals processed by all audio processing circuits.
[0047] It should be noted that the signal quality of the audio signal may include at least one parameter of signal strength, signal-to-noise ratio, dynamic range, and bandwidth.
[0048] Reference Figure 5 , Figure 5 2 is an optional schematic diagram of the signal indicator 200 provided by the embodiment of the present invention. It is understood that the signal indicator 200 may include a display screen 210, which may be in communication with the signal detection circuit, so that the signal quality of the audio signal received by each receiving antenna 110 detected by the signal detection circuit may be displayed on the display screen 210, for example, Figure 5 In the example, the display screen 210 may use numbers to represent the signal quality of the audio signal. A larger number indicates a higher signal quality of the audio signal. Figure 3It can be seen that the wireless audio receiver 100 is provided with antenna 1, antenna 2, and antenna 3. The display screen 210 can display the corresponding mark of each signal receiving antenna: antenna 1, antenna 2, and antenna 3, as well as the corresponding signal quality. Among them, the signal quality of the audio signal received by the signal receiving circuit corresponding to antenna 1 is the highest. The display screen 210 can also be connected to the audio switching switch in communication, and the switching selection status of the audio switching switch can be displayed on the display screen 210, that is, which receiving antenna 110 is selected and which receiving antenna 110's corresponding signal receiving circuit receives the audio signal for subsequent audio processing and playback, so that the user can intuitively understand, for example Figure 3 As shown, the display screen 210 shows that the antenna 1 is selected, that is, the current audio switching switch is in a state of connecting the signal receiving circuit corresponding to the antenna 1 with the audio processing circuit.
[0049] Reference Figure 6 , Figure 6 2 is an optional schematic diagram of the signal indicator 200 provided by the embodiment of the present invention. It is understood that the signal indicator 200 may include a plurality of indicator light components, which may be in communication with the signal detection circuit, so that the signal quality of the audio signal received by each signal receiving circuit detected by the signal detection circuit can be displayed through the indicator light components. For example, Figure 6 In the indicator light assembly, a plurality of signal quality indicator lights 220 are provided. Each signal quality indicator light 220 corresponds to each signal receiving circuit. Different light colors of the signal quality indicator lights 220 can represent different signal qualities. Figure 6 It can be seen that there are three signal quality indicators 220, which correspond to the signal receiving circuits corresponding to antenna 1, antenna 2 and antenna 3 provided in the wireless audio receiver 100. The indicator light component can also be connected to the audio switch, so that the current switching status of the audio switch can be displayed by the indicator light component. For example, Figure 6 As shown, antenna 2 in the receiving antenna 110 is selected, that is, the signal receiving circuit corresponding to antenna 2 is selected, then the signal quality indicator light 220 corresponding to antenna 2 is lit, and the other signal quality indicators 220 are off.
[0050] It is understood that the signal indicator 200 may be provided with a magnetic structure 230, and the wireless microphone and / or the wireless audio receiver 100 may be provided with a magnetic member 231 that matches the magnetic structure 230. Therefore, the signal indicator 200 may be fixed to the wireless microphone or the wireless audio receiver 100 through the magnetic attraction between the magnetic structure 230 and the magnetic member 231. For example, referring to Figure 7 , Figure 7 This is an optional schematic diagram of the installation of the signal indicator 200 provided in the embodiment of the present utility model. Figure 7 In the embodiment of the present invention, a plurality of magnetic members 231 can be provided on the outside of the housing of the wireless microphone, and the signal indicator 200 is provided with a groove matching the shape of the housing of the wireless microphone, and a magnetic attraction structure 230 is provided in the groove, so that the signal indicator 200 can be snapped onto the outside of the housing of the wireless microphone through the groove, and the signal indicator 200 is fixed to the wireless microphone through the magnetic attraction between the magnetic member 231 on the outside of the housing of the wireless microphone and the magnetic attraction structure 230 in the groove. Furthermore, when using the wireless microphone, the current signal reception status of the wireless audio receiver 100 can be remotely and intuitively understood through the signal indicator 200, which facilitates the user to make timely adjustments. Fixing the signal indicator 200 on the wireless audio receiver 100 can facilitate the storage and placement of the signal indicator 200, thereby preventing the signal indicator 200 from being lost. At the same time, when the wireless microphone is used within a close range of the wireless audio receiver 100, it can be directly fixed to the wireless audio receiver 100 without having to fix it to the wireless microphone to increase the weight of the wireless microphone, thus adapting to different usage scenarios.
[0051] It is understood that the signal indicator 200 may also be provided with a threaded structure 240, and the wireless microphone and / or the wireless audio receiver 100 may be provided with a threaded connector 241 that matches the threaded structure 240. Therefore, the signal indicator 200 may be fixed to the wireless microphone or the wireless audio receiver 100 by the threaded connection between the threaded structure 240 and the threaded connector 241. For example, referring to Figure 8 , Figure 8 This is an optional schematic diagram of the installation of the signal indicator 200 provided in the embodiment of the present utility model. Figure 8 In the embodiment, a threaded connector 241 extending outward may be provided at the bottom of the wireless microphone, and a threaded structure 240 recessed inward may be provided on one side of the signal indicator 200. The threaded connector 241 cooperates with the threaded structure 240 to fix the signal indicator 200 to the bottom of the wireless microphone. Thus, during the use of the wireless microphone, the current signal reception status of the wireless audio receiver 100 can be remotely understood in real time through the signal indicator 200, which facilitates the user to adjust the wireless microphone.
[0052] It should be noted that the signal indicator 200 can be installed and fixed on any device that can cooperate with the magnetic structure 230 or the threaded structure 240 through the magnetic structure 230 or the threaded structure 240, and is not limited to being installed and fixed on the wireless microphone and the wireless audio receiver 100.
[0053] It is understandable that the audio switching circuit in the wireless audio receiver 100 and the signal indicator 200 can be connected to each other by wired or wireless communication. Figure 9 , Figure 9 This is an optional schematic diagram of the communication connection between the signal indicator 200 and the wireless audio receiver 100 provided in the embodiment of the present invention. Figure 9 In the embodiment, both the wireless audio receiver 100 and the signal indicator 200 can be provided with a communication interface 250 for data transmission, so that the communication interfaces 250 of the wireless audio receiver 100 and the signal indicator 200 can be connected respectively through a data transmission line, thereby realizing a wired communication connection between the audio switching circuit and the signal indicator 200.
[0054] In addition, refer to Figure 10 , Figure 10 This is an optional schematic diagram of the communication connection between the signal indicator 200 and the wireless audio receiver 100 provided in the embodiment of the present invention.
