Description

Technical Field

[0001] This utility model relates to the field of microphones, and in particular to an adapter for a wireless microphone receiver and a wireless microphone system. Background Technology

[0002] A typical wireless microphone system consists of a transmitter (TX) and a receiver (RX). The transmitter is responsible for collecting and sending audio signals, while the receiver connects to a terminal device such as a mobile phone or camera to receive and output audio signals. Currently, there are two main types of receivers on the market, one specifically for mobile phones and the other for cameras, each adapting to different interface standards and physical connection methods.

[0003] In related technologies, wireless microphone receivers for smartphones typically use a USB-C interface (Android system) or a Lightning interface (iOS system) to connect directly to the phone, enabling the transmission of digital audio signals. These mobile phone receivers are compact, plug-and-play, and meet the convenience requirements of mobile shooting. Meanwhile, for professional imaging equipment such as digital cameras and SLR cameras, dedicated camera receivers are available on the market. These receivers are usually equipped with a 3.5mm TRS / TRRS analog audio interface and feature dedicated mechanical connection structures such as cold shoe or hot shoe mounts for secure mounting on the camera body.

[0004] However, the relevant technical solutions have obvious shortcomings. The mobile phone receiver and the camera receiver differ fundamentally in their interface types. The mobile phone version uses a USB-C or Lightning digital interface, while the camera primarily uses a 3.5mm analog audio interface. These two are completely incompatible in terms of electrical standards and physical dimensions, making it impossible to use the mobile phone receiver for camera shooting scenarios. When users create content using both a mobile phone and a camera simultaneously, they need to purchase two separate wireless microphone systems, increasing equipment procurement costs.

[0005] The main purpose of this invention is to provide an adapter for a wireless microphone receiver, which aims to solve the problem that mobile phone receivers cannot be used in photographic equipment.

[0006] To achieve the above objectives, this utility model proposes a wireless microphone receiver adapter for use in photographic equipment. The wireless microphone receiver adapter includes an adapter base with a bearing surface for supporting the receiver. A protrusion is formed on the bearing surface, located on one side edge of the adapter base. The side wall of the protrusion is provided with a transmission interface for the receiver to be inserted. The side of the adapter base facing away from the bearing surface is provided with a connection part for connecting to the photographic equipment.

[0007] In some embodiments, the protrusion extends along the edge of the adapter.

[0008] In some embodiments, the photographic device includes a hot shoe groove with a first contact point disposed therein; the connection portion includes a hot shoe plate adapted to the hot shoe groove, the hot shoe plate having a second contact point for contacting the first contact point.

[0011] In some embodiments, the outer surface of the adapter is provided with a charging interface that is electrically connected to the main control board.

[0012] In some embodiments, the outer surface of the adapter is further provided with an audio interface that is electrically connected to the main control board, and the audio interface is spaced apart from the charging interface.

[0013] In some embodiments, the side of the connecting portion facing away from the adapter is provided with a locking member, and the outer surface of the adapter is also provided with an unlocking button that is linked to the locking member.

[0014] In some embodiments, the outer surface of the adapter is further provided with function buttons for user operation, and the function buttons are spaced apart from the charging interface.

[0015] This utility model further proposes a wireless microphone system, including a receiver. The receiver includes a connector that is plugged into the output interface of an adapter for the wireless microphone receiver. The adapter for the wireless microphone receiver is the same as the adapter for the wireless microphone receiver in the aforementioned embodiment.

[0016] The beneficial effects of this utility model are as follows: By setting up an adapter with a bearing surface and a raised structure, wherein the raised sidewall is equipped with a transmission interface for plugging in a mobile phone receiver, and the back of the adapter is provided with a connecting part for connecting to photographic equipment, compatibility and adaptation are achieved between existing USB-C or Lightning interface mobile phone receivers and cameras and other photographic equipment.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0024] The adapter in this embodiment is mainly used to make existing USB-C or Lightning interface mobile phone receivers compatible with cameras and other photographic equipment. This allows receivers that were originally only compatible with smartphones to be used with professional photographic equipment, solving the problem that mobile phone receivers cannot be used with photographic equipment. See details... Figure 1 and Figure 2 This utility model provides an adapter for a wireless microphone receiver. The adapter includes an adapter base with a bearing surface for supporting the receiver. A protrusion is formed on the bearing surface, located on one side edge of the adapter base. The side wall of the protrusion is provided with a transmission interface for the receiver to be inserted. The side of the adapter base facing away from the bearing surface is provided with a connection part for connecting to a photographic device.

[0025] The adapter 100 in this embodiment is a connection and adaptation structure between a wireless microphone receiver 200 and a photographic device. The adapter 100 can be L-shaped, T-shaped, or a rectangular plate, etc., without particular limitation. Its material can be engineering plastic, lightweight materials such as aluminum alloy or magnesium alloy, ensuring structural strength without excessive burden on the photographic device. The adapter 100 has a bearing surface 101 for supporting the receiver 200. The bearing surface 101 can be provided with anti-slip textures or silicone anti-slip pads to increase friction and prevent the receiver 200 from slipping. It can also be provided with a limiting structure for positioning the receiver 200, such as positioning protrusions, positioning grooves, or snap-fit ​​structures, facilitating quick installation and ensuring the receiver 200's stable position.

[0026] A protrusion 102 is constructed on the bearing surface 101. The protrusion 102 is located on one side edge of the adapter 100. The side wall of the protrusion 102 is provided with a transmission interface 102a for the receiver 200 to be plugged in. The transmission interface 102a can be any one of USB Type-C interface, Lightning interface, or Micro USB interface. Of course, in other embodiments, the interface can be made into a replaceable module, and different types of interfaces can be replaced by magnetic, snap or threaded connection to be compatible with receivers 200 with different interface types, thereby improving the versatility of the adapter 100.

[0027] The adapter 100 can also integrate a main control board, which includes an interface conversion chip, signal processing circuits, etc., to realize signal conversion and processing, such as converting digital audio signals into analog audio signals, or realizing functions such as signal gain adjustment and noise reduction.

[0028] The adapter 100 has a connection part 103 for connecting to a photographic device on the side opposite to the bearing surface 101. The connection part 103 is mainly used to connect the adapter 100 to the photographic device. The connection part 103 can be a hot shoe with electrical contacts, a cold shoe for connecting only, or a threaded hole structure for connecting to the photographic device through a standard thread.

[0029] To enable communication and power supply between the receiver 200 and the camera, a hot shoe interface is preferred, allowing direct power intake from the camera and transmission of audio signals. Additionally, the adapter 100 can house a main control board for signal processing, format conversion, volume adjustment, and other functions, and can support more features through firmware upgrades. Furthermore, the adapter 100 can be equipped with indicator lights to display operating status, pairing status, and other information; and an audio monitoring interface for real-time monitoring of recording quality.

[0030] When applied to photographic equipment (such as cameras or camcorders), the connecting part 103 of the adapter 100 is connected to the hot shoe or cold shoe of the camera to achieve relative fixation. If necessary, the locking knob on the hot shoe can be tightened to enhance stability.

[0031] Next, place the receiver 200 of the wireless microphone on the bearing surface 101 of the adapter 100. Simultaneously, plug the receiver 200 into the transmission interface 102a on the protrusion 102, gently pressing it to ensure full insertion and a good connection. If the adapter 100 has a limiting structure, the receiver 200 will automatically position itself correctly. At this point, the installation of the camera / video equipment is complete; the entire installation process is simple and quick.

[0032] The transmitter of the wireless microphone is worn on the user's collar or belt. After powering on, the receiver 200 and the transmitter are paired. Once paired successfully, the indicator light will show the corresponding status.

[0033] After pairing is complete, during actual transmission, the transmitter picks up the sound and converts it into a radio frequency signal for transmission. The receiver 200 receives the signal transmitted by the transmitter and converts it into an audio signal for output. If the connection unit 103 uses a hot shoe interface, the audio signal can be directly transmitted to the camera's audio input channel through the hot shoe for recording with the camera, without the need for an additional audio cable. Users can view the audio level in real time in the camera's audio monitoring function to ensure recording quality.

[0034] If the connector 103 uses a cold shoe interface, the user can adjust the volume, switch channels, and check battery levels using the buttons on the receiver 200 while operating the camera, offering flexible operation. Simultaneously, the user can connect headphones via the audio monitoring interface on the receiver 200 for real-time monitoring, allowing for timely identification and resolution of recording problems. Furthermore, the audio signal from the receiver 200 can be connected via an audio cable to the camera's external microphone interface, or to other devices such as mobile phones and computers, enabling multi-device recording.

[0035] The beneficial effects of this utility model are as follows: By setting up an adapter 100 with a bearing surface 101 and a protrusion 102, wherein the side wall of the protrusion 102 is equipped with a transmission interface 102a for plugging in a mobile phone receiver 200, and the back of the adapter 100 is provided with a connecting part 103 for connecting to photographic equipment, the adapter achieves compatibility and adaptation between existing USB-C or Lightning interface mobile phone receivers 200 and cameras and other photographic equipment. This allows receivers 200, which were originally only applicable to smartphones, to be used with professional photographic equipment, solving the problem that mobile phone receivers 200 cannot be used with photographic equipment. In addition, this solution eliminates the need for users to repeatedly purchase a dedicated wireless microphone system for camera shooting, reducing equipment upgrade costs and avoiding redundant investment in functions. One set of mobile phone wireless microphones can serve both mobile phone shooting and professional camera shooting. At the same time, this adapter has good universal compatibility and can adapt to mobile phone receivers 200 of different brands with the same interface standard. Through the design of replaceable interface modules, it can support multiple interface types. In addition, the adapter 100 is compact, portable, and easy to install without the need for professional tools, which improves ease of use and shooting efficiency.

[0036] Continue reading Figure 1 and Figure 2 In a preferred embodiment, the protrusion 102 extends along the edge of the adapter 100. This extension of the protrusion 102 along the edge of the adapter 100 serves to limit the receiver 200, preventing lateral movement or deflection of the receiver 200 on the bearing surface 101 and ensuring a stable connection between the receiver 200 and the transmission interface 102a. The extension length of the protrusion 102 can be adapted to the width of the receiver 200, allowing the sides of the receiver 200 to fit against the protrusion 102, forming lateral support. In other embodiments, limiting baffles can be provided at both ends of the protrusion 102. These limiting baffles are perpendicular to the bearing surface 101, forming limiting constraints on the front and rear ends of the receiver 200. After the receiver 200 is installed, this further ensures stable limiting, preventing the receiver 200 from loosening or falling off due to vibration or movement during shooting, thus improving the overall stability and reliability of the structure.

[0037] In a preferred embodiment, a direct-insertion connection can also be used. For example, a insertion groove is recessed in the bearing surface 101, and a transmission interface 102a is provided at the bottom of the groove. The depth and width of the insertion groove match the external dimensions of the receiver 200. In this way, the receiver 200 can be directly placed in the insertion groove and simultaneously inserted into the transmission interface 102a at the bottom of the groove. The groove walls provide lateral restraint for the receiver 200, resulting in a more stable installation and more precise positioning. This direct-insertion structure not only simplifies the installation process—users only need to vertically insert the receiver 200 into the insertion groove to complete the installation—but the insertion groove also protects the receiver 200, reducing the risk of impact or collision. Furthermore, the design of the insertion groove can be customized to fit the shape of receivers 200 from different brands, providing better compatibility and versatility.

[0038] See Figure 3 In a preferred embodiment, the photographic device includes a hot shoe (not shown), with a first contact disposed within the hot shoe. The connecting portion 103 includes a hot shoe plate 104 adapted to the hot shoe, and the hot shoe plate 104 has a second contact 104a for contacting the first contact. Thus, by employing a hot shoe connection, data transmission between the adapter 100 and the photographic device can be achieved. When the hot shoe plate 104 is inserted into the hot shoe, the second contact 104a on the hot shoe plate 104 contacts the first contact within the hot shoe, forming an electrical connection path. The audio signal received by the receiver 200 can be transmitted through the internal circuitry of the adapter 100 to the second contact 104a, and then transmitted to the audio input channel of the photographic device via the contact between the second contact 104a and the first contact, enabling synchronous audio and video recording without the need for additional audio cables, simplifying wiring operations and improving ease of use and system integration. The structure of the hot shoe plate 104 conforms to the standard hot shoe interface specification, ensuring good compatibility and stable connection with the hot shoe slots of mainstream camera brands on the market.

[0039] In a preferred embodiment, power supply can also be achieved via hot shoe contacts. The camera device supplies power to the second contact 104a of the adapter 100 through the first contact within the hot shoe slot. The main control board and receiver 200 inside the adapter 100 can directly obtain operating power from the camera device. This eliminates the need for the receiver 200 to rely on its own built-in battery, or allows it to automatically switch to external power when the built-in battery is low, improving the receiver 200's battery life. This is suitable for long-duration shooting scenarios and prevents recording interruptions due to the receiver 200 running out of power. Furthermore, hot shoe power supply reduces the charging frequency of the receiver 200.

[0040] In another preferred embodiment, the photographic equipment includes a cold shoe mount, and the connecting part 103 includes a cold shoe plate 105 adapted to the cold shoe mount. Thus, the cold shoe connection method primarily achieves a mechanical fixed connection between the adapter 100 and the photographic equipment. The cold shoe plate 105 is inserted into the cold shoe mount through a standard dovetail groove structure, forming a stable physical connection and ensuring that the adapter 100 will not fall off due to vibration or movement during shooting. The cold shoe plate 105 has a simple structure and does not have electrical contacts, therefore it does not have data transmission and power supply functions. However, this design gives the adapter 100 wider compatibility, enabling it to adapt to any photographic equipment with a standard cold shoe mount, including some cameras, camcorders, stabilizers, monitors, and other devices that do not support hot shoe communication. In this embodiment, the audio signal output of the receiver 200 needs to be transmitted through the receiver 200's own audio output interface, such as a 3.5mm audio jack, via an audio cable to the external microphone input interface of the photographic equipment. The adapter 100, which uses a cold shoe connection, has a lower cost and a simpler structure. It also allows users to flexibly adjust the parameters of the receiver 200, such as volume, channel, and monitoring, while operating the camera equipment, making operation more independent and free.

[0041] In a preferred embodiment, a main control board and a battery are spaced apart within the adapter 100, with the main control board electrically connected to the transmission interface 102a and the battery, respectively. By integrating the main control board and battery within the adapter 100, the adapter 100 can be independently powered and operated without relying on the power supply of the camera equipment or receiver 200. The main control board can integrate core circuit modules such as a signal processing chip, an interface conversion chip, and a power management chip, enabling it to perform data format conversion, signal gain adjustment, and noise reduction on the audio signal output from the receiver 200, ensuring that the audio signal is transmitted to the camera equipment with optimal quality.

[0042] The battery provides a stable power supply to the main control board and receiver 200, improving the overall system's endurance and making it suitable for outdoor shooting, long-term recording, and other scenarios, preventing work interruptions due to insufficient power. The battery can be a lithium battery or a lithium polymer battery, and its capacity can be configured according to actual usage needs. The adapter 100 can also be equipped with a charging interface 111, such as a USB Type-C charging port, for convenient battery charging. The main control board and battery can adopt a modular design, fixed in different areas inside the adapter 100 and spaced apart, which facilitates heat dissipation and maintenance, as well as future upgrades or replacements. For example, when the battery ages or its capacity degrades, the battery module can be replaced individually without replacing the entire adapter 100, reducing maintenance costs, extending product lifespan, and improving system flexibility and maintainability.

[0043] See Figures 1 to 3In a preferred embodiment, the outer surface of the adapter 100 is further provided with an audio interface 112 for electrical connection to the main control board, with the audio interface 112 spaced apart from the charging interface 111. Thus, by providing the audio interface 112 on the outer surface of the adapter 100, real-time audio signal output and monitoring functions can be achieved. The audio interface 112 can be a 3.5mm standard audio jack or a 6.35mm professional audio jack. Users can connect wired headphones or monitoring equipment through this audio interface 112 to monitor the recording effect in real time, promptly identify and adjust recording problems, and ensure audio quality.

[0044] The audio interface 112 and the charging interface 111 are spaced apart at different locations on the adapter 100 to avoid cable interference when used simultaneously, thus improving ease of use. In a preferred embodiment, multiple audio interfaces 112 can be provided, such as two or three audio output interfaces. This allows the photographer to monitor through one audio interface 112 while other audio interfaces 112 transmit audio signals to monitoring devices for simultaneous monitoring by the director, sound engineer, or other staff, enabling collaborative monitoring and audio quality control. Multiple audio interfaces 112 can be connected in parallel to output the same audio signal, or they can be independently controlled by the main control board to output audio signals with different gains or different channels, meeting the needs of different usage scenarios. In addition, the audio interface 112 can also serve as an audio output channel to transmit audio signals to external recording equipment, mixing consoles, or amplification systems, realizing multi-channel distribution and application expansion of audio signals, enhancing the functionality and professionalism of the adapter 100.

[0045] See Figure 3 In a preferred embodiment, the side of the connecting part 103 facing away from the adapter 100 is provided with a locking member 107. The outer surface of the adapter 100 is also provided with an unlocking key 108 that is linked to the locking member 107. The locking member 107 is a locking structure that is compatible with both hot and cold shoes. When the connecting part 103 of the adapter 100 is inserted into the hot shoe or cold shoe of the photographic equipment, the locking member 107 automatically engages in the locking position and cooperates with the slot or limiting structure in the hot shoe or cold shoe to form a reliable mechanical lock, preventing the adapter 100 from accidentally falling off during use due to vibration, movement or external force.

[0046] The locking element 107 can take the form of a spring clip, a spring-loaded locking structure, or a sliding locking pin, achieving locking and unlocking functions through elastic deformation or mechanical sliding. When the user needs to disassemble the adapter 100, simply press or move the unlock button 108 on the outer surface of the adapter 100. The unlock button 108, through an internal linkage mechanism, causes the locking element 107 to disengage from the slot or release the locking force, allowing the adapter 100 to be easily removed from the hot or cold shoe. The unlock button 108 is located in an easily accessible area on the outer surface of the adapter 100, such as the side or top, allowing the user to complete the unlocking operation with one hand, making it simple and quick. This design enhances the stability and reliability of the connection between the adapter 100 and the photographic equipment while ensuring ease of disassembly, avoiding the cumbersome operation of repeated rotation required by traditional knob locking methods.

[0047] See Figure 3 In a preferred embodiment, the outer surface of the adapter 100 is also provided with function buttons 113 for user operation, with the function buttons 113 spaced apart from the charging interface 111. Thus, by providing function buttons 113 on the outer surface of the adapter 100, users can easily and quickly adjust and control various functions of the adapter 100 during use without disassembling or interrupting shooting. The function buttons 113 and the charging interface 111 are spaced apart at different positions on the adapter 100 to avoid accidental button presses during charging or interference with the charging cable connection when operating the buttons, improving operational convenience and safety.

[0048] Specifically, the adapter 100 has a 3.5mm audio interface 112 on its outer surface. This audio interface 112 can be connected to the 3.5mm audio input interface on the camera via a double-ended 3.5mm adapter cable to transmit audio signals. This is suitable for scenarios using a cold shoe connection or cameras that do not support hot shoe audio transmission. The recording mode switching button 113 is a toggle switch. Users can toggle this switch left and right to switch between stereo and mono recording modes, flexibly selecting the audio format according to different recording needs. Stereo mode is suitable for ambient sound acquisition and music recording, while mono mode is suitable for human dialogue and interview recording. The power button is used to control the power on and off of the adapter 100. Users can press and hold the power button to turn the adapter 100 on or off. When the adapter 100 is on, the main control board and related circuits start working; when it is off, it saves power and extends standby time.

[0049] The adapter 100 also features a USB-C charging port. Since the adapter 100 has a built-in battery, the charging port provides an external power input function. Users can connect a charger or power bank via a USB-C charging cable to charge the battery, and it supports charging while using, providing longer battery life in long shooting scenarios and avoiding interruption of recording due to insufficient power.

[0050] The connector 103 can adopt a hybrid design of SONY-Mi interface and cold shoe interface. The SONY-Mi intelligent multi-functional hot shoe interface integrates data communication, digital audio signal transmission, power supply and control functions, enabling complete functional docking with the hot shoe of Sony cameras. This interface has a built-in locking structure for securely fixing it to the hot shoe of the camera body, ensuring reliable connection. When the cold shoe plate 105 or hot shoe plate 104 is fixed to the camera, the built-in locking structure will automatically lock with the camera body to prevent the adapter 100 from falling off. The outer surface of the adapter 100 is also provided with an unlock button 108. When the user needs to remove the adapter, pressing the unlock button 108 will release the locking structure, allowing the adapter 100 to be easily removed from the camera's hot shoe or cold shoe. The operation is simple and quick, requiring no tools or complicated procedures.

[0051] See Figure 4 This utility model further proposes a wireless microphone system, including a receiver 200. The receiver 200 includes a connector 201, which is plugged into the output interface of an adapter for the wireless microphone receiver 200. The adapter for the wireless microphone receiver 200 is the same as the adapter for the wireless microphone receiver 200 described in the previous embodiment. The specific structure of the adapter for the main wireless microphone receiver 200 is as described in the above embodiment. Since this wireless microphone system adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0052] Specifically, the wireless microphone system of this embodiment includes a transmitter and a receiver 200. The transmitter is used to pick up sound and convert it into a radio frequency signal for transmission, while the receiver 200 is used to receive the radio frequency signal and convert it back into an audio signal for output. The connector 201 of the receiver 200 can be a standard interface such as a USB Type-C plug, a Lightning plug, or a Micro USB plug, which matches the transmission interface 102a on the side wall of the adapter device. In use, the connector 201 of the receiver 200 is inserted into the transmission interface 102a of the adapter device to achieve electrical connection and mechanical fixation between the receiver 200 and the adapter device. The audio signal output by the receiver 200 is transmitted through the transmission interface 102a to the main control board inside the adapter device or directly to the camera equipment.

[0053] This wireless microphone system achieves compatibility between the receiver 200, which was originally only applicable to smartphones, and professional photography equipment through an adapter, expanding the application scenarios of the wireless microphone system and improving equipment utilization and usage flexibility.

[0054] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
