Detailed Implementation

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] This utility model embodiment provides a recording device with a wireless charging power bank, such as... Figures 1 to 7 As shown, it includes: a housing 10 and a power module 20, a recording module 30 and a wireless charging module 40 disposed within the housing 10; the recording module 30 includes a recording circuit board 310 and an integrated chip 320, an antenna assembly and a recording microphone 340 disposed on the recording circuit board 310, the integrated chip 320 includes a recording module and a communication transmission module, the recording module obtains audio information through the recording microphone, and the communication transmission module realizes communication through the antenna assembly; the wireless charging module is used to charge external mobile devices.

[0021] The recording device of this embodiment integrates the communication transmission module into the integrated chip 320 of the recording module 30, avoiding the need to set up separate components to realize the communication function. This effectively controls the overall size of the device, enabling the device to have communication function without increasing the overall size of the recording device, while still maintaining the original size structure. This solves the problem of increased device size in the prior art, making it convenient for users to carry and use.

[0022] The recording module 30 is a key component for audio acquisition and communication interaction. It includes a recording circuit board 310, an integrated chip 320, an antenna assembly, and a recording microphone 340 integrated on the circuit board. The integrated chip 320 integrates both a recording module and a communication transmission module. The antenna assembly and the recording microphone 340 are electrically connected to the integrated chip 320. The recording module is specifically responsible for acquiring audio information. It establishes a connection with the recording microphone 340, which captures sound signals from the surrounding environment and converts them into processable audio information. The communication transmission module is used for communication functions. It relies on the antenna assembly to interact with the outside world, enabling bidirectional transmission of audio signals and meeting the real-time communication needs of scenarios such as remote conferencing. The wireless charging module 40 is mainly used to charge external mobile devices. When external mobile devices (such as mobile phones, tablets, etc.) need to be recharged, the wireless charging module 40 can provide power through wireless induction, ensuring the reliability of the recording equipment during use.

[0023] As a preferred embodiment, refer to Figure 1 , Figure 3 and Figure 4 The antenna assembly includes a first antenna 331 and a second antenna 332, which are distributed on opposite sides of the recording circuit board 310, and the orthographic projections of the first antenna 331 and the second antenna 332 on the recording circuit board 310 are offset. The communication transmission module includes a Bluetooth module and a WIFI module. The Bluetooth module is electrically connected to the first antenna 331, and the WIFI module is electrically connected to the second antenna 332.

[0024] In this embodiment, the first antenna 331 and the second antenna 332 are distributed on opposite sides of the recording circuit board 310 with their orthographic projections offset. This layout fully utilizes the free space of the recording circuit board 310, achieving efficient use of its space and helping to further control the overall size of the recording device, meeting the design requirements for portability. At the same time, it maximizes the physical distance between the two antennas, reducing their electromagnetic coupling and thus significantly reducing the mutual interference between Bluetooth and Wi-Fi signals.

[0025] Meanwhile, the one-to-one connection between the Bluetooth module and the first antenna 331, and the WIFI module and the second antenna 332, enables each communication module to transmit signals through its dedicated antenna, further ensuring the stability of signal transmission and thus improving the communication quality of the recording device. This ensures that the bidirectional transmission of audio signals is clear and smooth in scenarios such as remote conferencing, avoiding problems such as sound stuttering and distortion caused by signal interference.

[0026] As a preferred embodiment, refer to Figure 4 There are two recording microphones 340, which are distributed along the width direction at opposite ends of the recording circuit board 310. The second antenna 332 is located between the two recording microphones 340.

[0027] The recording microphone 340 has two microphones that can capture sound signals from different angles, forming a wider sound pickup coverage area. The two recording microphones 340 are distributed along the width direction at opposite ends of the recording circuit board 310. This width-direction distribution maximizes the distance between the two recording microphones within the limited size of the recording circuit board 310, thus avoiding mutual interference between them to some extent. The second antenna 332 is located between the two recording microphones 340. This layout cleverly places the second antenna 332 in the space between the two recording microphones, making the distribution of each component on the recording circuit board 310 more compact and orderly, avoiding wasted space, further maintaining the size of the recording module 30, and thus ensuring the portability of the device.

[0028] Figure 5 In the diagram, the X direction represents the length, the Y direction represents the width, and the Z direction represents the vertical direction.

[0029] As a preferred embodiment, the distance between the first antenna 331 and the second antenna 332 is greater than 30mm, and the distance between the two recording microphones 340 is greater than 45mm.

[0030] The spacing between the first antenna 331 and the second antenna 332 is greater than 30mm, which further enhances the anti-interference effect and ensures that the recording device can maintain a stable communication connection and achieve smooth audio signal transmission in scenarios with high communication quality requirements, such as remote conferencing. Simultaneously, the spacing between the two recording microphones is greater than 45mm. On the one hand, this allows the two microphones to capture sound signals from different angles, forming a wider sound pickup coverage area; on the other hand, it reduces the signal interference intensity between the two microphones, making the independent sound signals captured by each microphone stronger, further improving the clarity of the recorded sound quality and providing users with a high-quality recording experience.

[0031] As a preferred embodiment, both the first antenna 331 and the second antenna 332 are ceramic antennas.

[0032] Ceramic antennas are characterized by their small size; under the same communication performance requirements, their dimensions are much smaller than those of traditional metal antennas. Applying ceramic antennas to the recording device of this embodiment significantly reduces the space occupied by the antenna assembly on the recording circuit board 310, freeing up more space for other components and further optimizing the layout of the recording circuit board 310. This effectively controls the overall size of the recording device, making it more compact and portable, thus ensuring its portability.

[0033] As a preferred embodiment, refer to Figure 1 , Figures 3 to 5 The recording circuit board 310 is also provided with a sound guide 350. The number of sound guides 350 matches the number of recording microphones 340 and is set one-to-one with each recording microphone 340. The recording circuit board 310 has a first sound guide hole 301 for connecting the sound guides 350 and the recording microphones 340. The sound guides 350 and the first antenna 331 are located on the same side of the recording circuit board 310. The first antenna 331 and the integrated chip 320 are located between the two sound guides 350.

[0034] The sound guide 350 guides sound to the recording microphone 340 more effectively. To achieve smooth sound transmission, a first sound guide hole 301 is formed on the recording circuit board 310. The first sound guide hole 301 is specifically used to connect the sound guide 350 and the recording microphone 340, so that external sound can enter the first sound guide hole 301 through the sound guide 350 and be accurately transmitted to the recording microphone 340. This reduces sound loss and interference during transmission, enabling the recording microphone 340 to capture the target sound signal more accurately and clearly, improving the sensitivity and clarity of recording, enhancing recording quality, and meeting the demand for high-quality recording in remote conferencing.

[0035] By placing the sound guide 350 and the first antenna 331 on the same side of the recording circuit board 310, and placing the first antenna 331 and the integrated chip 320 between the two sound guides 350, this layout makes full use of the space of the recording circuit board 310. The space between the two sound guides 350 is effectively utilized to accommodate the first antenna 331 and the integrated chip 320, making the components on the entire recording circuit board 310 more compact and orderly, avoiding the scattered arrangement of the components. More functional components are integrated within the limited area of ​​the recording circuit board 310, providing strong support for controlling the size of the entire recording device and ensuring the portability of the device.

[0036] The sound guide 350 in this embodiment is typically made of a material with excellent acoustic properties (such as silicone, ABS resin, etc.), and no specific limitation is made here.

[0037] As a preferred embodiment, refer to Figure 1 The recording circuit board 310 is also provided with a storage chip 360. The storage chip 360 and the sound guide 350 are located on the same side of the recording circuit board 310, and the storage chip 360 is located between the first antenna 331 and one of the sound guides 350. The storage chip 360 is used to store audio information.

[0038] The storage chip 360 enables the recording device in this embodiment to have the function of local audio information storage. It is electrically connected to the integrated chip 320, so users can save the recording content without relying on external storage devices (such as USB flash drives, mobile hard drives, etc.), which improves the ease of use of the recording device.

[0039] The storage chip 360 is positioned between the first antenna 331 and one of the sound guides 350, making full use of the unused space between them. This avoids occupying other areas of the recording circuit board 310 for the installation of the storage chip 360, and also eliminates the need to increase the overall size of the recording circuit board 310, further ensuring that the entire recording device remains compact and portable.

[0040] The integrated chip 320 and the memory chip 360 in this embodiment both use existing devices, which will not be described in detail here.

[0041] As a preferred embodiment, refer to Figure 2 , Figures 5 to 7The housing 10 includes a cover plate 110 and a bottom shell 120 that interlock with each other. The cover plate 110 and the bottom shell 120 enclose a receiving space. The power module 20, the recording module 30 and the wireless charging module 40 are all located in the receiving space. A second sound guide hole 1201 is formed on the bottom shell 120. The sound guide 350 is located on the side close to the second sound guide hole 1201. The power module 20 includes a battery 210 and a main control circuit board 210. The main control circuit board 210 and the recording circuit board 310 are distributed along the length direction on opposite sides of the battery 210. The main control circuit board 210 is electrically connected to the battery 210 and the recording circuit board 310 respectively. The recording circuit board 310 is located vertically inside the housing 10.

[0042] When the cover plate 110 and the bottom shell 120 are fastened together, they form a relatively enclosed space, which protects the internal components from dust and impacts, and allows for positioning and installation through a reasonable structural design (such as slots and screw holes). This split structure facilitates the installation and maintenance of internal components. The second sound guide hole 1201 is located on the bottom shell 120, corresponding to the position of the sound guide 350 of the recording module 30, which shortens the transmission path of sound from the outside to the recording microphone, reduces signal attenuation during transmission, and further ensures recording quality.

[0043] The power module 20 includes a battery 210 and a main control circuit board 210. The main control circuit board 210 serves as the control core of the power module 20, establishing electrical connections with both the battery 210 and the recording circuit board 310. On one hand, the main control circuit board 210 obtains power from the battery 210, processes and distributes the power, providing stable power to the recording circuit board 310. On the other hand, the main control circuit board 210 can also monitor and control the charging and discharging state of the battery 210, ensuring its safe use. Simultaneously, the main control circuit board 210 and the recording circuit board 310 are distributed along the length of the battery 210 on opposite sides of the battery 210. This layout fully utilizes the space along the length of the battery 210, avoiding stacking or crowding of modules within the housing 10. The recording circuit board 310 is vertically positioned within the housing 10, further optimizing the space utilization within the housing 10.

[0044] As a preferred embodiment, refer to Figures 5 to 7 The wireless charging module 40 is located on the side of the battery 210 near the cover plate 110, and includes a coil 410 and a magnetic attractor 420 located on the outer periphery of the coil 410. The coil 410 is electrically connected to the main control circuit board 210.

[0045] The wireless charging module 40 allows external devices that support wireless charging to be directly attached to the cover 110 via the magnetic attachment 420, eliminating the need for an additional charging cable and further simplifying the user experience. Users can record audio while charging, preventing recording from being interrupted by low battery power, significantly enhancing the device's versatility and ease of use. The wireless charging module 40 is located on the side of the battery 210 closest to the cover 110. This placement maximizes the use of internal space in the recording device, preventing the wireless charging module 40 from encroaching on the installation area of ​​the recording module 30 or the power module 20, ensuring a compact overall structure and maintaining portability.

[0046] As a preferred embodiment, refer to Figure 5 and Figure 6 The main control circuit board 210 includes a first circuit board 211 and a second circuit board 212 that are electrically connected. The coil 410 is electrically connected to the first circuit board 211. The battery 210 and the recording circuit board 310 are connected to the second circuit board 212. The first circuit board 211 and the second circuit board 212 are parallel to each other and horizontally arranged in the accommodating space.

[0047] The main control circuit board 210 is divided into a first circuit board 211 (wireless charging control) and a second circuit board 212 (battery management and recording control), reducing electromagnetic interference between different functional modules. For example, the electromagnetic signal generated by the wireless charging coil 410 control circuit of the first circuit board 211 will not directly affect the recording signal processing circuit of the second circuit board 212, ensuring that the recording module 30 can stably output high-quality recording signals and the wireless charging module 40 can work stably, greatly improving the working stability of each functional module and thus providing users with a high-quality recording experience. The first circuit board 211 and the second circuit board 212 are arranged horizontally, saving space within the housing 10 and providing installation space for the connecting lines (such as wires) between the two circuit boards.
