Technical Field

[0001] The present invention relates to the technical field of microphones, and in particular to a control method for a wireless microphone receiver. Background Art

[0002] Microphone, scientifically known as microphone, is also called microphone and micro-phone. Microphone is an energy conversion device that converts sound signals into electrical signals. Most microphones are electret condenser microphones, which work by using a polymer vibration membrane with permanent charge isolation to change its resistance through sound, thereby generating a current signal. With the development of microelectronics technology in recent years, wireless microphones have been widely used in fields such as live video broadcasting.

[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 allowing digital products to communicate with mobile phones while charging the mobile phones through the two Type-c ports. However, the existing wireless microphone receivers realize the method of charging and using at the same time by designing one Type-c port as a male port and the other Type-c port as a female port. This design has restricted the use of the device. 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 be inconvenient to use on some devices; the existing technology also has a display expansion screen, which is provided with two Type-c female ports, which supports data and charging to be inserted at will and can be adaptive, but this design also has disadvantages. It can only be used in scenarios where the mobile phone is used as the host. At the same time, this solution does not support the use of Type-c to USB-A. And with the popularity of Type-c adapters, this design does not have a protection mechanism for related misoperation; if both ports are plugged into power adapters, there will be a risk of damaging the device.

[0012] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0013] Embodiment 1

MOS-A controls the power conduction of Type-c female port-A, MOS-B controls the power conduction of Type-c female port-B, and MOS-C controls the power conduction of the PD protocol chip. The power conversion module is also powered by an external device through an external interface, which is a conventional technology in the prior art, so it is not elaborated in detail in this embodiment. The USB analog switch is used to control which Type-c female port the external interface communicates with. There is a switch inside the USB analog 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. 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; A control method for a wireless microphone receiver, such as Figure 1 As shown, it specifically includes the following steps: S1. Detect whether there is a device inserted into Type-c female port-A and Type-c female port-B. If it is detected that a first device is inserted into one of the Type-c female ports, control the power conversion module to turn on the power of the Type-c female port inserted with the first device (that is, if the Type-c female port-A is inserted with the first device, then control MOS-A in the power conversion module to turn on; if the Type-c female port-B is inserted with the first device, then control MOS-B in the power conversion module to turn on). At the same time, control the power conversion module to turn on the power of the PD protocol chip (that is, control MOS-C in the control power conversion module to turn on). At this time, turn on the first The device is used as a power source, the first device supplies power to the PD protocol chip, and the first device supplies power to the peripheral module at the same time; then the USB analog switch is controlled to turn to the Type-c female port inserted into the first device (that is, if the Type-c female port-A is inserted into the first device, the USB analog switch is controlled to turn to the A port, if the Type-c female port-B is inserted into the first device, the USB analog switch is controlled to turn to the B port), at this time, the first device is used as the host, and the first device communicates with the peripheral module; then it is determined whether the first device is a power device or a host device, if the first device is a power device, jump to step S2; if the first device is a host device, jump to step S5; S2, detect whether there is a second device inserted into another Type-c female port, 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 determined to be a power supply device, jump to step S3; if the second device is determined to be a host device, jump to step S4; S3, control the power conversion module to turn off the power of the Type-c female port inserted into the second device, while maintaining the power of the Type-c female port inserted into the first device and the power of the PD protocol chip turned on. At this time, the first device is still used as the power source, 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 the Type-c female port inserted into the first device, at this time, the first device is still used as the host, and the first device communicates with the peripheral module; S4, control the power conversion module to turn on the power of the Type-c female port inserted into the second device, and keep the power of the Type-c female port inserted into the first device turned on and the power of the PD protocol chip turned on. At this time, the first device is still used as the power source, the first device supplies power to the PD protocol chip, the first device supplies power to the peripheral module, and the first device supplies power to the second device at the same time; then control the PD protocol chip to communicate with the second device, if the communication does not time out, the second device supports the PD protocol, control the USB analog switch to turn to the Type-c female port inserted into the second device, at this time, the second device is used as the host, and the second device communicates with the peripheral module, if the communication times out, the second device does not support the PD protocol, control the power conversion module to turn off the power of the Type-c female port inserted into the first device, at this time, the second device is used as the power source, the second device supplies power to the PD protocol chip, and the second device supplies power to the peripheral module, and then control the USB analog switch to turn to the Type-c female port inserted into the second device, at this time, the second device is used as the host, and the second device communicates with the peripheral module; S5, detecting whether there is a second device inserted into the other Type-C female port, if not, returning to step S5 to continue detecting, if yes, jumping to step S6; S6, control the power conversion module to turn on the power of the Type-c female port inserted into the second device, and keep the power of the Type-c female port inserted into the first device and the power of the PD protocol chip turned on. At this time, the second device is used as the power source, 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 control the PD protocol chip to communicate with the first device. If the communication does not time out, the first device supports the PD protocol. At this time, maintain the USB analog switch to turn to the Type-c female port inserted into the first device. At this time, the first device acts as a host and communicates with the peripheral module; if the communication times out, the first device does not support the PD protocol, control the power conversion module to turn off the power of the Type-c female port inserted into the second device, and at this time, use the first device as the power source, the first device supplies power to the PD protocol chip, and at the same time, the first device supplies power to the peripheral module, and then maintain the USB analog switch to turn to the Type-c female port inserted into the first device. At this time, the first device acts as a host and communicates with the peripheral module.

[0015] The PD protocol chip is used to identify whether the power supply device or the host device is plugged into the Type-c female port, and whether the host device supports the PD protocol is also identified by the PD protocol chip. This is a function of the PD protocol chip itself, so it is not elaborated again; That is, when only one Type-c female port is plugged into a device, no matter what device it is, it is operated as a power source and a host. The power source refers to supplying power to the internal module and the peripheral module, and the host refers to communicating with the peripheral module. When a power device is first plugged into one Type-c female port, and then another Type-c female port is also plugged into a power device, the first plugged in power device acts as both a power source and a host; When a power supply device is first inserted into one Type-c female port, and then a host device is inserted into the other Type-c female port, it is necessary to determine whether the host device supports the PD protocol. If it supports the PD protocol, the power supply device acts as a power supply to supply power to the host device, and then the host device communicates with the peripheral module; if it does not support the PD protocol, the host device acts as both a power supply and a host; When one Type-c female port is first plugged into the host device, and then the other Type-c female port is plugged into the power supply device, it is necessary to determine whether the host device supports the PD protocol. If it supports the PD protocol, the power supply device acts as a power supply to the host device, and then the host device communicates with the peripheral module; if it does not support the PD protocol, the host device acts as both a power supply and a host; When a host device is first inserted into one of the Type-c female ports, and then another host device is also inserted into the other Type-c female port, it is necessary to determine whether the first inserted host supports the PD protocol. If it supports the PD protocol, the second inserted host device acts as a power source and the first inserted host device acts as a host; if it does not support the PD protocol, the first inserted host device acts as both a power source and a host.

[0016] Embodiment 2: The difference from Embodiment 1 is that in Embodiment 2, when one of the Type-c female ports is first plugged into a host device, and then the other Type-c female port is also plugged into a host device, it is necessary to first determine whether the first plugged in host supports the PD protocol. If it is determined that the first plugged in host device does not support the PD protocol, it is also necessary to determine whether the second plugged in host device supports the PD protocol. If the second plugged in host device supports the PD protocol, the second plugged in host device is used as the host and the first plugged in host device is used as the power supply. If the second plugged in host device does not support the PD protocol, the first plugged in host device is used as both the power supply and the host.

A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
