TECHNICAL FIELD

[0001] The present application relates to the technical field of microphones, in particular to a control method of a wireless microphone receiver. BACKGROUND

[0002] A microphone, also known as a microphone, is a device that converts sound signals into electrical signals. Most microphones are electret condenser microphones, which work by using a polymeric material with permanent charge isolation diaphragm, changing its resistance value through sound, and generating current signals. With the development of microelectronics technology in recent years, wireless microphones have been widely used in video live broadcast and other fields.

[0003] The wireless microphone receiver is an important part of the wireless microphone. The wireless microphone receiver generally includes two Type-c ports, which can realize the function of communicating with the mobile phone and charging the mobile phone through the two Type-c ports. However, the existing wireless microphone receiver uses a method to realize the edge charging function by designing one of the Type-c ports as a male head and the other as a female port. This design has limited the use of the device, and only devices with Type-c female ports can be used. At the same time, the direction of the data port and the charging port is fixed, which may cause inconvenience in use on some devices. The existing technology also has a display expansion screen with two Type-c female ports, which supports random insertion of data and charging and can be self-adaptive. However, this design also has drawbacks. It can only be used in scenarios where a mobile phone is used as a host, and it does not support Type-c to USB-A use. Moreover, with the popularity of Type-c adapters, this design does not have a protection mechanism for related misoperations. If both ports are plugged into a power adapter, there is a risk of damaging the device. SUMMARY

BRIEF DESCRIPTION OF DRAWINGS

[0018] Figure 1This is a flowchart illustrating a control method for a wireless microphone receiver.

[0019] Figure 2 This is a block diagram of a wireless microphone receiver. Detailed Implementation

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] Example 1

[0022] A wireless microphone receiver, such as Figure 2 As shown, it includes a Type-C female port-A, a Type-C female port-B, a USB analog switch, a power conversion module, and a PD protocol chip. The wireless microphone receiver is also connected to a peripheral module, but the peripheral module is not part of the wireless microphone receiver. Specifically:

[0023] The power conversion module internally includes MOS-A, MOS-B, and MOS-C, which are respectively connected to Type-C female port-A, Type-C female port-B, and the PD protocol chip. MOS-A controls the power supply to Type-C female port-A, MOS-B controls the power supply to Type-C female port-B, and MOS-C controls the power supply to the PD protocol chip. The power conversion module also supplies power to external devices through an external interface, which is a conventional technology in the prior art, so it is not elaborated in detail in this embodiment.

[0024] The USB analog switch is used to control which Type-C female port the external interface communicates with. It has an internal switch. When the switch is switched to port A, the external interface communicates with Type-C female port A. When the switch is switched to port B, the external interface communicates with Type-C female port B. This is a conventional technology in the prior art, so it is not elaborated in detail in this embodiment.

[0025] The PD protocol chip is used to identify whether the device plugged into the Type-C female port is a power supply device or a host device, and can also identify whether the host device supports the PD protocol. It is a conventional chip in the prior art, so it is not described in detail in this embodiment.

[0026] A control method for a wireless microphone receiver, such as Figure 1 As shown, it specifically includes the following steps:

[0027] S1, detect whether Type-c female port-A and Type-c female port-B have a device inserted, if one of the Type-c female ports has a first device inserted, control the power conversion module to make the Type-c female port where the first device is inserted power on (i.e. if Type-c female port-A has a first device inserted, control MOS-A in the power conversion module to open, if Type-c female port-B has a first device inserted, control MOS-B in the power conversion module to open), at the same time control the power conversion module to make the PD protocol chip power on (i.e. control MOS-C in the power conversion module to open), at this time the first device is used as a power supply, the first device supplies power to the PD protocol chip, and the first device supplies power to the peripheral module; then control the USB analog switch to turn to the Type-c female port where the first device is inserted (i.e. if Type-c female port-A has a first device inserted, control the USB analog switch to turn to A port, if Type-c female port-B has a first device inserted, control the USB analog switch to turn to B port), at this time the first device is used as a host, and the first device communicates with the peripheral module; then determine whether the first device is a power supply device or a host device, if the first device is a power supply device, jump to step S2; if the first device is a host device, jump to step S5;

[0028] S2, detect whether the other Type-c female port has a second device inserted, if not, return to step S2 to continue detection, if yes, determine whether the second device is a power supply device or a host device, if the second device is a power supply device, jump to step S3; if the second device is a host device, jump to step S4;

[0029] S3, control the power conversion module to make the Type-c female port where the second device is inserted power off, at the same time maintain the Type-c female port where the first device is inserted power on and the PD protocol chip power on, at this time the first device is still used as a power supply, the first device supplies power to the PD protocol chip, and the first device supplies power to the peripheral module; then continue to maintain the USB analog switch to turn to the Type-c female port where the first device is inserted, at this time the first device is still used as a host, and the first device communicates with the peripheral module;

[0030] S4, the power conversion module is controlled to make the Type-c female port inserted into the second device power on, while maintaining the Type-c female port inserted into the first device power on and the PD protocol chip power on, at this time the first device is still used as a power supply, the first device supplies power to the PD protocol chip, the first device supplies power to the peripheral module, and at the same time the first device supplies power to the second device; then the PD protocol chip is controlled to communicate with the second device, if the communication does not time out, the second device supports the PD protocol, the USB analog switch is controlled to switch to the Type-c female port inserted into the second device, at this time the second device is used as a host, the second device communicates with the peripheral module, if the communication times out, the second device does not support the PD protocol, the power conversion module is controlled to make the Type-c female port inserted into the first device power off, at this time the second device is used as a power supply, the second device supplies power to the PD protocol chip, and at the same time the second device supplies power to the peripheral module, then the USB analog switch is controlled to switch to the Type-c female port inserted into the second device, at this time the second device is used as a host, the second device communicates with the peripheral module;

[0031] S5, whether another Type-c female port has a second device inserted is detected, if not, returning to step S5 to continue detection, if yes, jumping to step S6;

[0032] S6, the power conversion module is controlled to make the Type-c female port inserted into the second device power on, while maintaining the Type-c female port inserted into the first device power on and the PD protocol chip power on, at this time the second device is used as a power supply, the second device supplies power to the PD protocol chip, the second device supplies power to the peripheral module, and at the same time the second device supplies power to the first device; then the PD protocol chip is controlled to communicate with the first device, if the communication does not time out, the first device supports the PD protocol, at this time the USB analog switch is maintained to switch to the Type-c female port inserted into the first device, at this time the first device is used as a host, the first device communicates with the peripheral module; if the communication times out, the first device does not support the PD protocol, the power conversion module is controlled to make the Type-c female port inserted into the second device power off, at this time the first device is used as a power supply, the first device supplies power to the PD protocol chip, and at the same time the first device supplies power to the peripheral module, then the USB analog switch is maintained to switch to the Type-c female port inserted into the first device, at this time the first device is used as a host, the first device communicates with the peripheral module.

[0033] Whether the Type-c female port inserted is a power supply device or a host device is identified by the PD protocol chip, and whether the host device supports the PD protocol is also identified by the PD protocol chip, which is a function of the PD protocol chip itself, so it is not expanded again in detail;

[0034] That is, when only one Type-c female port is inserted into the device, regardless of the device, it is operated as a power supply and a host to the device. The power supply refers to power supply to the internal module and the peripheral module, and the host refers to communication with the peripheral module.

[0035] When one of the Type-c female ports is first inserted into a power supply device, and the other Type-c female port is also inserted into a power supply device, the first inserted power supply device is used as a power supply and a host at this time.

[0036] When one of the Type-c female ports is first inserted into a power supply device, and the other Type-c female port is inserted into a host device, it is necessary to determine whether the host device supports the PD protocol at this time. If the PD protocol is supported, the power supply device is used as a power supply to supply power to the host device, and then the host device communicates with the peripheral module. If the PD protocol is not supported, the host device is used as a power supply and a host.

[0037] When one of the Type-c female ports is first inserted into a host device, and the other Type-c female port is inserted into a power supply device, it is necessary to determine whether the host device supports the PD protocol at this time. If the PD protocol is supported, the power supply device is used as a power supply to supply power to the host device, and then the host device communicates with the peripheral module. If the PD protocol is not supported, the host device is used as a power supply and a host.

[0038] When one of the Type-c female ports is first inserted into a host device, and the other Type-c female port is also inserted into a host device, it is necessary to determine whether the first inserted host supports the PD protocol at this time. If the PD protocol is supported, the second inserted host device is used as a power supply, and the first inserted host device is used as a host. If the PD protocol is not supported, the first inserted host device is used as a power supply and a host.

[0039] Embodiment Two:

[0040] The difference between Embodiment One and Embodiment Two is that in Embodiment Two, when one of the Type-c female ports is first inserted into a host device, and the other Type-c female port is also inserted into a host device, it is necessary to first determine whether the first inserted host supports the PD protocol. If it is determined that the first inserted host device does not support the PD protocol, it is also necessary to determine whether the second inserted host device supports the PD protocol. If the second inserted host device supports the PD protocol, the second inserted host device is used as a host, and the first inserted host device is used as a power supply. If the second inserted host device does not support the PD protocol, the first inserted host device is used as a power supply and a host.

[0041] Although the embodiments of the present application have been shown and described above, it is understood that the above-described embodiments are exemplary and are not to be construed as limiting the present application, and that changes, modifications, substitutions and variations can be made by those skilled in the art without departing from the scope of the present application.

[0042] Various changes and modifications will no doubt occur to those skilled in the art once they have read the foregoing description. It is intended to embrace all such changes and modifications in the scope of the appended claims. Any and all equivalents are intended to be encompassed by the following claims.
