Description

Technical Field

[0001] This utility model relates to a split-type infant voice monitoring device, belonging to the technical field of infant monitoring devices. Background Technology

[0002] Infants and toddlers typically lack the ability to accurately express their needs through language, often relying on crying to indicate hunger, discomfort, or other needs. To help parents or caregivers monitor the infant's condition at all times, infant voice monitoring devices can be used to pick up and identify cries, assisting caregivers in making judgments and providing reference information based on different types of infant cries.

[0003] Most existing infant voice monitoring devices are plug-in integrated monitoring units, usually placed next to the crib. After collecting the baby's voice information, they are processed and corresponding reminders are issued to help caregivers understand the baby's needs. However, when the baby is away from the crib, the infant cannot carry the voice monitoring device with them, resulting in the device not being able to collect voice information in a timely manner. Caregivers cannot receive the prompts of the baby crying immediately, and the baby's needs cannot be detected in a timely manner.

[0004] Therefore, a split-type infant voice monitoring device was designed, which includes a separate microphone and a separate display, as well as a combined housing that provides storage space and charging position for the microphone and display. When the caregiver needs to leave the infant temporarily, the microphone can be left with the infant or taken out and worn by the infant. The caregiver can wear the display to conduct remote wireless voice monitoring. Summary of the Invention

[0034] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0035] like Figures 1-3 As shown, this split-type infant voice monitoring device includes a pickup unit 1, a display unit 2, and a combined housing 3.

[0036] The microphone pickup unit 1 includes a voice acquisition and processing module 101 for acquiring external voice and converting it into a digital audio signal, and a first wireless communication module 102 electrically connected to the voice acquisition and processing module 101. It also includes a first built-in battery 103 that powers the voice acquisition and processing module 101 and the first wireless communication module 102. The voice acquisition and processing module 101 includes a microphone unit for acquiring external voice and an analog-to-digital converter (ADC) for converting the analog audio signal acquired by the microphone unit into a digital audio signal. The digital audio signal is transmitted to the display unit 2 via the first wireless communication module 102 (using Bluetooth, Wi-Fi, global cellular network, or other communication modules). The microphone pickup unit 1 is powered by a built-in lithium battery. The microphone pickup unit 1 can optionally use a wireless microphone with a highly integrated wireless microphone chip (such as Nordic nRF52840, Qualcomm QCC series, etc.), which integrates audio acquisition, processing, and wireless transmission functions, simplifying the complexity and size of the microphone pickup unit 1. A clip 104 for wearing is provided on the microphone pickup unit 1.

[0037] Display unit 2 includes a processor module 201, a second wireless communication module 202 electrically connected to the processor module 201, a display module 203, and an alert module (buzzer 204, vibrator 205). It also includes a second built-in battery 206 that powers the processor module 201, the second wireless communication module 202, the display module 203, the buzzer 204, and the vibrator 205. The second wireless communication module 202 receives digital audio signals sent by the first wireless communication module 102. Display unit 2 uses a Qualcomm or MediaTek SoC with high integration, which not only includes the processor module 201 but also integrates the second wireless communication module 202 (Bluetooth, Wi-Fi, global cellular network, etc. communication modules). The display module 203 uses an AMOLED screen or an LCD screen; AMOLED screens offer vibrant colors and high contrast, while LCD screens have low power consumption and lower cost. After receiving the digital audio signal from the microphone unit 1, the second wireless communication module 202 processes it through the processor module 201 and, based on the processing result, sends corresponding reminders to the guardian via the display module 203, buzzer 204, and vibrator 205. The display unit 2 can be a commercially available smartwatch, which wirelessly pairs and communicates with the microphone unit 1.

[0038] like Figures 3-5 As shown, the combined housing 3 includes a base 301 and a cover 302 fixed on the base 301. The upper part of one side of the cover 302 has a display opening 303 and the lower part has a step portion 304 with a microphone hole 311. The display unit 2 is fixed and tightly attached to the inside of the display opening 303 after being fixed by the elastic telescopic charging bracket 6. The microphone unit 1 is fixed on the base 301 below the step portion 304 and is charged through the base 301.

[0039] This assembly is easy to assemble and disassemble. Installation and charging process: First, separate the cover 302 and the base 301. Then, place the microphone unit 1 and the display unit 2 into their respective charging positions, and then replace the cover 302. At this point, to expose the display module 203 (display screen) of the display unit 2 and ensure a seamless connection between the display opening 303 and the display module 203, use the elastic telescopic charging bracket 6 to push the display unit 1 against the inside of the display opening 303, ensuring a tight fit. For disassembly, simply separate the cover 302 and the base 301, then remove the microphone unit 1 and the display unit 2 for separate use.

[0040] When the caregiver needs to leave the baby briefly, the microphone unit 1 and display unit 2 are activated and paired. The two communicate in real time via a low-power Bluetooth module. The microphone unit 1 can be left next to the baby or clipped to the baby's clothing near the baby's mouth using clip 104, for real-time collection of the baby's voice.

[0041] The guardian will remove the second display unit and wear it on their body. For example, the second display unit can be made into a watch shape (such as...). Figure 3 As shown), it can be worn on the wrist; the two parts can be made into pendants or necklaces and worn on the chest.

[0042] When the sound pickup unit 1 is working, it collects the baby's voice and converts it into a digital audio signal, which is then sent to the display unit 2 via the first wireless communication module 102 (e.g., Bluetooth 5.0 protocol). The processor module 201 of the display unit 2 processes the voice signal and determines whether to issue an alert. For example, the processor module 201 uses the volume and duration of the sound as its criteria. When the processor module 201 detects that the volume of the baby's cry is greater than a set value, or the duration of the cry exceeds a set duration, it issues an alarm alert through the built-in display module 203 (displaying reminder graphics), buzzer 204 (ringing alert), and vibrator 205 (vibrating alert when silent). This is especially suitable for caregivers who need to wear headphones while temporarily leaving the baby, and for caregivers in noisy environments where it is difficult to detect the baby's crying; in such cases, the wearable display unit 2 can provide an alert.

[0043] When the microphone unit 1 and the display unit 2 are placed inside the combined housing 3 for charging, the display module 203 can be exposed through the display opening 303. The display module 203 can display some graphic and textual information, such as time, wallpaper, weather, and the number of reminders issued today, serving as a desktop ornament that can display graphic and textual information.

[0044] The combined pickup unit 1 and display unit 2 can also serve as the hardware foundation for a voice recognition device. For example, when used with existing or future more accurate infant voice recognition software, it can translate different cries of an infant into the infant's current needs, and display the infant's current status (hunger, sleepiness, hiccups, discomfort, gas, etc.) on display unit 2 using graphics and text. The caregiver can then promptly obtain the infant's current status by observing the graphics and text on display unit 2.

[0045] like Figure 4 , Figure 6 As shown, in some embodiments, the elastic telescopic charging bracket 6 includes a hollow support rod 601 fixed to the base 301, an elastic telescopic rod 602 fixed to the top of the support rod 601 and coaxially arranged with the central axis of the display opening 303, and a second magnetic charging base 603 fixed to the telescopic end of the elastic telescopic rod 602 and used to fix the display unit 2. The second magnetic charging base 603 restricts the center of the display module 203 to the central axis of the display opening 303. A flexible dustproof gasket 305 is provided on the inner edge of the display opening 303, and the edge of the display unit 2 is tightly fitted to the display opening 303 by the flexible dustproof gasket 305.

[0046] The elastic telescopic rod 602 includes a sleeve 6021, a piston 6022, an inner rod 6023, a spring 6024, and a bottom cover 6025. The sleeve 6021 is fixed to the top of the support rod 601 and is coaxially arranged with the central axis of the display opening 303. One end of the sleeve 6021 has a telescopic end opening with the same outer diameter as the inner rod 6023, and the other end of the sleeve 6021 has a bottom opening with the same outer diameter as the piston 6022. The sleeve 6021 has a rib 6026 arranged along the axial direction inside. The piston 6022 has a groove 6027 on its edge that mates with the rib 6026. The groove 6027 and the rib 6026 cooperate to prevent the piston 6022 from rotating inside the sleeve 6021. One end of the inner rod 6023 extends out from the telescopic end opening of the sleeve 6021 and is fixed perpendicularly to the center of the second magnetic charging base 603. The other end of the inner rod 6023 is connected to the piston 6022, which is restricted to translational movement inside the sleeve 6021. A spring 6024 is set between the bottom of the piston 6022 and the bottom of the sleeve 6021. The spring 6024 is pressed into the sleeve 6021 by the bottom cover 6025. The bottom cover 6025 is screwed to the sleeve 6021.

[0047] With the continuous updates and iterations of the display unit 2 product, the thickness of the display unit 2 designed at different times may vary, resulting in gaps at the contact point between the display module 203 and the display opening 303, causing the combined housing 3 to no longer fit. To improve compatibility, an elastic telescopic rod 602 is used to fix the second magnetic charging base 603. The elastic telescopic rod 602 is coaxially set with the central axis of the display opening 303, allowing the display unit 2 to rest against the display opening 303. A flexible dustproof gasket 305 provides cushioning, sealing, and anti-slip properties. The elastic telescopic rod 602 can only move along the central axis of the display opening 303. Regardless of the thickness, the center of the display module 203 is always located on the central axis of the display opening 303, aligning the center of the display module 203 with the center of the display opening 303, thus ensuring compatibility with display units 2 of various thicknesses.

[0048] In some embodiments, the second magnetic charging base 603 and the display unit 2 are respectively provided with second magnetic blocks 4 that are attracted and fixed to each other at corresponding positions. The second magnetic charging base 603 and the display unit 2 are charged through charging contacts or a wireless charging module.

[0049] When charging is performed using charging contacts, the charging contacts of the second built-in battery 206 charging circuit are located outside the display unit 2 under the action of magnetic attraction. At the corresponding position, the charging contacts contact the elastic charging contacts provided on the second magnetic charging base 603, connecting the first built-in battery 103 into the charging circuit for charging.

[0050] When using a wireless charging module, the device is also attracted and fixed by magnetic attraction. At this time, the wireless charging receiver module built into the display unit 2 is coupled with the wireless charging transmitter module built into the second magnetic charging base 603 to achieve wireless charging.

[0051] The display unit 2 is fixed to the second magnetic charging base 603 by magnetic attraction, which is convenient and quick to assemble and disassemble, and facilitates quick switching between separate use, combined use, and charging.

[0052] In some embodiments, a first magnetic charging base 310 for fixing the microphone assembly 1 is provided on the base 301, and first magnetic blocks 5 are respectively provided at corresponding positions inside the first magnetic charging base 310 and the microphone assembly 1 to attract and fix each other. The first magnetic charging base 310 and the microphone assembly 1 are charged through charging contacts or a wireless charging module.

[0053] Similarly, the charging method of the first built-in battery 103 is similar to that of the second built-in battery 206.

[0054] During wired charging, the charging contacts are located on the outside of the microphone unit 1 and contact the elastic charging contacts on the first magnetic charging base 310 to perform wired charging.

[0055] During wireless charging, the wireless charging receiver module built into the microphone unit 1 is coupled with the wireless charging transmitter module built into the first magnetic charging base 310 to achieve wireless charging.

[0056] The microphone unit 1 is fixed to the first magnetic charging base 310 by magnetic attraction, which is convenient for quick assembly and disassembly and facilitates rapid switching between separate use, combined use, and charging.

[0057] like Figure 2 , Figure 5 As shown, in some embodiments, quick-release magnetic blocks 306 that attract each other are fixed on the contact surfaces of the base 301 and the cover 302, respectively. A boss 307 is provided in the middle of the base 301, and a positioning block 308 is provided on the base 301 outside the boss 307. A positioning groove 309 that mates with the positioning block 308 is provided at a corresponding position on the cover 302. The bottom opening of the cover 302 mates with the outer edge of the boss 307. The boss 307 has a through-hole for wiring.

[0058] The base 301 and the cover 302 are fixed by magnetic attraction, which allows for quick switching of usage modes. At the same time, the positioning block 308 cooperates with the positioning groove 309, and the boss 307 cooperates with the bottom opening of the cover 302, which can quickly complete the positioning of the base 301 and the cover 302, so that the display unit 2 can be accurately exposed from the display opening after assembly, and the sound pickup unit 1 can be accurately aligned with the position of the sound pickup hole 311.

[0059] The voice acquisition modules are concentrated in the microphone unit 1, and the processor, display and other modules are concentrated in the display unit 2. The two can be worn separately and communicate wirelessly, which can promptly and conveniently understand whether the baby is crying. In addition, when the microphone unit 1 and the display unit 2 are out of power, they can be put back into the combined shell 3 for charging. At this time, the microphone unit 1 and the display unit 2, when combined, can serve as the hardware foundation of a real-time voice recognition device.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
