[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] Reference Figures 1 to 4 The present application provides a multifunctional wireless microphone, which includes: a transmitter 320, a housing 102, a sound receiving module 400 and a control module. The housing 102 is used to accommodate the transmitter 320; the sound receiving module 400 is arranged in the housing 102; the control module is electrically connected to the sound receiving module 400; when the control module receives a signal instruction to continue receiving sound, the sound receiving module 400 is switched from a standby state to a working state, and the sound receiving module 400 receives sound alone; or when the control module receives a signal instruction to continue receiving sound, the sound receiving module 400 is switched from a standby state to a working state, and the sound receiving module 400 and the transmitter 320 receive sound together.

[0029] According to the above structure, in the multifunctional wireless microphone involved in the present application, when the transmitter 320 is exhausted or fails, etc., which is not suitable for using the transmitter 320 to receive sound, the sound receiving module 400 in the housing 102 can replace the transmitter 320 for receiving sound to ensure the continuity of the receiving work. Specifically, the wireless microphone involved in the present invention can also receive sound through the sound receiving module 400 in the housing 102 when the transmitter 320 is charging. Compared with traditional microphones, the transmitter 320 will heat up when receiving sound while charging, thereby affecting the quality of sound reception. The transmitter 320 of the present application does not need to perform the sound receiving action when charging, but continues to receive sound by setting the sound receiving module 400, which does not affect the sound receiving effect, and can ensure good sound receiving quality even when the transmitter 320 is charging. In addition, according to the scene requirements, the transmitter 320 and the sound receiving module 400 can receive sound together to realize multi-object directional sound reception of the wireless microphone and improve the practicality of the wireless microphone.

[0030] In some embodiments, a plurality of sound receiving modules 400 are provided, and in the containing shell 102, the plurality of sound receiving modules 400 are evenly distributed along the circumference of the containing shell 102. Thus, the distribution of the plurality of sound receiving modules 400 can achieve an omnidirectional sound receiving effect.

[0031] In some examples, the multifunctional wireless microphone may be provided with two sound receiving modules 400, the two sound receiving modules 400 are symmetrically arranged, and the sound receiving directions of the two sound receiving modules 400 are opposite to each other. In this way, the sound receiving area formed by the two sound receiving modules 400 can basically achieve 360-degree omnidirectional sound receiving. In other embodiments, in order to further improve the sound receiving effect, the multifunctional wireless microphone may also be provided with three, four or more sound receiving modules 400. Along the circumference of the containing shell 102, a plurality of sound receiving modules 400 are evenly distributed. Thus, the distribution structure of the plurality of sound receiving modules 400 can enhance the omnidirectional sound receiving effect of the multifunctional wireless microphone, and better adapt to the needs of the use scenarios such as conferences and desktop games that require omnidirectional recording. Specifically, the number of sound receiving modules 400 can be set according to the needs of customers to flexibly adapt to a variety of use scenarios.

[0032] Reference Figure 2 and Figure 3In some embodiments, the multifunctional wireless microphone further includes a battery 240, which is disposed in the housing 102; the sound receiving module 400 is disposed between the battery 240 and the housing 102, and a heat shield 430 is disposed between the sound receiving module 400 and the battery 240. Specifically, the battery 240 supplies power to the transmitter 320 and the sound receiving module 400, and during the charging process, the battery 240 generates a certain amount of heat. In order to reduce the potential interference of the heat generated by the battery 240 on the sound receiving module 400, the provision of the heat shield 430 can better isolate the heat, prevent the heat from being directly conducted to the sound receiving module 400, and ensure that the sound receiving module 400 can still maintain excellent sound receiving performance during the charging process.

[0033] In other embodiments, a spacing space may be provided between the radio module 400 and the battery 240 , and the spacing space may form a heat dissipation space to promote air circulation, thereby reducing the effect of heating of the battery 240 on the radio module 400 .

[0034] In some embodiments, the transmitter 320 includes a first microphone core, and the sound receiving module 400 includes a second microphone core 420; the sensitivity of the second microphone core 420 is greater than that of the first microphone core. Among them, the second microphone core 420 has a higher sensitivity, which can also be understood as a larger capacitance value. Specifically, the second microphone core 420 can have a larger diaphragm area, or a smaller density of conductive material. As a result, the second microphone core 420 with a higher sensitivity can have a more stable signal and a lower noise level, so that the sound receiving module 400 can capture clearer and more delicate sound details and provide better sound receiving quality. It is understandable that some transmitters 320 are usually small in size in order to meet their portability and concealment, so the volume of the first microphone core is also small, which also limits the capacitance of the first microphone core. The sound receiving module 400 is arranged in the housing 102, which can fully utilize the space inside the housing 102 and use a second microphone core 420 with a larger capacitance. In the multifunctional wireless microphone provided in this embodiment, the second microphone core 420 of the sound receiving module 400 can meet the high-quality recording requirements, and cooperate with the first microphone core of the transmitter 320 to achieve recording operations with more sound qualities. For example, when a high-quality recording function is required, the user can directly use the sound receiving module 400 to receive sound.

[0035] In some embodiments, the sound receiving module 400 includes a shell, the second microphone core 420 is accommodated in the shell, and the shell is provided with a sound receiving hole. Specifically, on the containing shell 102, the area corresponding to the sound receiving hole can also be provided with a spray-proof net 410, which can reduce the spray-microphone noise, protect the sound receiving module 400, and also improve the sound quality.

[0036] Reference Figure 3In some examples, the transmitter 320 is provided with a first magnet 321, and the housing 102 is provided with a second magnet. When the transmitter 320 is placed in the housing 102, the first magnet 321 is magnetically connected with the second magnet. Thus, the magnetic connection allows the user to easily fix the transmitter in an appropriate position, and the magnetic effect can also play a certain role in guiding the placement.

[0037] In some embodiments, the multifunctional wireless microphone further includes a sensing module 500, which is disposed in the housing 102; the sensing module 500 is used to sense whether the transmitter 320 is located in the housing 102, and send a sensing signal to the control module. Specifically, after receiving the signal that the transmitter 320 is located in the housing 102, the control module can shut down the transmitter 320, and the transmitter 320 will not continue to receive sound.

[0038] Reference Figure 3 In some examples, the sensing module 500 may be a Hall sensor, which is arranged on the transmitter 320. When the transmitter 320 is in the sound receiving state, the first magnet 321 in the transmitter 320 has a preset value or no effect on the magnetic field generated by the Hall sensor, and the preset value is a magnetic field that will not significantly affect the Hall sensor. When the transmitter 320 is placed in the housing 102, the first magnet 321 and the second magnet are magnetically attracted. At this time, the magnetic field of the second magnet in the housing 102 will affect the Hall sensor. In addition, a magnetic rod 322 may also be provided in the housing 102. The magnetic rod 322 is used to extend the effect of the magnetic field. The effect of the magnetic field will cause the Hall sensor to generate an electric potential difference. After the control system of the transmitter 320 receives the electric potential difference signal, the transmitter 320 is shut down, and the transmitter 320 stops receiving sound. In other examples, the sensing module 500 may also be a pressure sensor, a switch circuit, a grating sensor, etc. Regarding the setting of the pressure sensor, the switch circuit, and the grating sensor, the setting may refer to the structure in the related art.

[0039] In some embodiments, the multifunctional wireless microphone further includes a receiver 310, a battery 240, a charging module control circuit board 210, and a sound receiving module 400 control circuit board 230; the housing 102 is provided with an opening for taking and placing the transmitter 320; along the direction of the opening toward the inside of the housing 102, the receiver 310, the charging module control circuit board 210, the battery 240, and the sound receiving module 400 control circuit board 230 are arranged in sequence; along the circumference of the housing 102, the transmitter 320 is arranged on one side of the receiver 310, and the sound receiving module 400 is arranged on one side of the sound receiving module 400 control circuit board 230. As a result, the multifunctional wireless microphone has a compact structure, and the design of the sound receiving module 400 fully utilizes the space inside the housing 102, so that the multifunctional wireless microphone can still be small and portable. The opening of the transmitter 320 is located near the opening of the housing 102, and the user can easily put in or take out the transmitter 320, which improves the convenience of use. In addition, along the circumference of the containing shell 102, the sound receiving module 400 is arranged on one side of the sound receiving module 400 control circuit board 230, which can also be understood as the sound receiving module 400 is located in the outermost edge area. This layout makes the internal structure more reasonable, and the sound receiving module 400 transmits more efficiently when receiving external audio signals, reducing signal interference.

[0040] In some embodiments, the multifunctional wireless microphone further includes a bracket, which is connected to the housing 102, and the bracket is used to support an external bearing surface. Thus, through the bracket, the multifunctional wireless microphone can be stably supported on the external bearing surface. Specifically, the external bearing surface can be a conference table such as a round table or a square table, so that the multifunctional wireless microphone can be suitable for use in some conference scenarios. Of course, the multifunctional wireless microphone can also be supported on a bearing surface such as the ground outdoors.

[0041] In some embodiments, the multifunctional wireless microphone further includes an upper cover 101, the housing shell 102 includes an opening for taking and placing the transmitter 320, the upper cover 101 is movably connected to the housing shell 102, and the upper cover 101 is used to cover the opening. Thus, the upper cover 101 can cover the housing shell 102, thereby effectively preventing dust, impurities and other external particles from entering the housing shell 102, thereby protecting the internal electronic devices from damage. Especially in outdoor workplaces, the life of the multifunctional wireless microphone can be significantly extended.

[0042] In some examples, the upper cover 101 can be rotatably connected to the housing 102 via a shaft 110 or a hinge. At one end of the upper cover 101 away from the shaft 110 or the hinge, the upper cover 101 can be snap-fitted to the housing 102. In other embodiments, the upper cover 101 and the housing box can also be magnetically connected.

[0043] In some examples, the upper cover 101 is provided with a first limiting step, and the area of ​​the containing shell 102 near the opening is provided with a second limiting step, and the outer contour of the first limiting step matches the outer contour of the second limiting step. When the upper cover 101 covers the containing shell 102, the first limiting step and the second limiting step are engaged and limited to limit the displacement of the upper cover 101 and the containing shell 102 in the circumferential direction.

[0044] Reference Figure 4 The present application also provides a control method for a multifunctional wireless microphone, which is applied to the multifunctional wireless microphone as above. The multifunctional microphone includes a transmitter 320 and a sound receiving module 400.

[0045] The control method of the multifunctional wireless microphone provided in the present application includes:

[0046] Receiving a signal command to continue receiving sound, switching the sound receiving module 400 from the standby state to the working state, and the sound receiving module 400 receives sound alone;

[0047] Alternatively, a signal instruction to continue receiving sound is received, and the sound receiving module 400 is switched from the standby state to the working state, and the sound receiving module 400 and the transmitter 320 receive sound together.

[0048] Specifically, refer to Figure 5 , the user can control which sound receiving mode to enter through the terminal device connected to the multifunctional wireless microphone. After the transmitter 320 is taken out of the housing 102, the user can select the sound receiving mode on the terminal device, wherein the sound receiving mode can include the transmitter 320 receiving sound alone, the sound receiving module 400 receiving sound alone, and the transmitter 320 and the sound receiving module 400 receiving sound together. When the user selects the transmitter 320 to receive sound alone on the terminal device, only the transmitter 320 switches to the working state at this time, and the transmitter 320 receives sound alone; when the user selects the sound receiving module 400 to receive sound alone on the terminal device, only the sound receiving module 400 switches to the working state at this time, and the sound receiving module 400 receives sound alone; when the user selects the transmitter 320 and the sound receiving module 400 to receive sound together on the terminal device, the transmitter 320 and the sound receiving module 400 switch to the working state synchronously and perform the sound receiving action synchronously.

[0049] In some embodiments, the control method of the multifunctional wireless microphone further includes:

[0050] Detecting the status of the transmitter 320;

[0051] When the transmitter 320 is in a non-operating state and is located in the housing 102 , the power level of the transmitter 320 is detected;

[0052] If the power level of the transmitter 320 is less than or equal to the preset value, the transmitter 320 is charged.

[0053] Specifically, the transmitter 320 may be provided with an electrical contact 220, and the charging module control circuit board 210 may be provided with a charging contact for being electrically connected to the electrical contact 220, and an identification module electrically connected to the charging contact. When the transmitter 320 is placed in the housing 102, when the electrical contact 220 of the transmitter 320 contacts the charging contact, the identification module in the transmitter 320 can send a power request instruction to the controller of the transmitter 320, and the controller of the transmitter 320 feeds back the power parameter to the identification module. The identification module compares the current power with the preset value. If the current power is lower than the preset value, the charging module performs a charging operation on the transmitter 320; if the current power is higher than or equal to the preset value, the charging module stops charging.

[0054] In some examples, the preset value may be 95%, that is, charging does not stop until the transmitter 320 is fully charged. Setting the preset value of 95% can help to increase the service life of the battery 240 in the transmitter 320.

[0055] In some examples, the electrical contact and the electrical terminal may adopt a charging pogo pin structure. Specifically, when the transmitter 320 is in a non-working state, the user can control whether to continue receiving sound through a terminal device connected to the multifunctional wireless microphone. In some examples, the housing 102 may also be provided with a control button, and the user can choose whether to continue receiving sound through the control case.

[0056] The sound receiving module 400 is in a non-working state by default. If the terminal device does not issue an instruction to continue receiving sound, the sound receiving module 400 remains in a non-working state and does not receive sound; if the terminal device issues an instruction to continue receiving sound, the sound receiving module 400 switches from a non-working state to a working state and continues receiving sound.

[0057] In some embodiments, the number of the sound receiving modules 400 is at least two.

[0058] Continue receiving instructions include:

[0059] Multi-directional sound reception command, all sound reception modules 400 are switched to working state;

[0060] One-way sound reception instruction, the sound reception module 400 in the preset direction is switched to the working state.

[0061] Thus, the user can select the sound receiving mode of the sound receiving module 400 on the terminal device according to the needs. When the use scenario of the multifunctional wireless microphone requires all-round sound receiving, such as all-round sound receiving is required in a meeting, the user can select multi-directional sound receiving, and the control module issues a multi-directional sound receiving instruction, and all the sound receiving modules 400 are switched to the working state. When only a certain direction is required for sound receiving, the user can select unidirectional sound receiving, and the control module issues a unidirectional sound receiving instruction, and only the sound receiving module 400 with the preset direction can be switched to the working state. The user can control one or more sound receiving modules 400 with the corresponding direction to receive sound according to the distribution of speakers on site.

[0062] In summary, the multifunctional wireless microphone involved in the present invention can receive sound through the sound receiving module 400 in the housing 102 when the transmitter 320 is charging. Compared with traditional microphones, the transmitter 320 will generate heat when receiving sound while charging, thereby affecting the quality of sound reception. The transmitter 320 of the present application does not need to perform the sound reception action when charging, but continues to receive sound by setting the sound receiving module 400, which does not affect the sound reception effect, and can ensure good sound reception quality even when the transmitter 320 is charging. In addition, according to the scene requirements, the transmitter and the sound receiving module can receive sound together to realize multi-object directional sound reception of the wireless microphone, thereby improving the practicality of the wireless microphone.
