Round Plastic Housing with Integrated Buzzer Cavity
Designed for Next-Generation Smart Home Security Vibration Alarms
This precision-engineered round plastic housing is the cornerstone of modern, reliable security alarm systems. Specifically designed to accommodate a buzzer cavity, it ensures optimal sound projection for vibration-based intrusion detection in smart homes, offices, and IoT security ecosystems. Built for durability, aesthetic integration, and superior acoustic performance.
Core Product Features & Specifications
| Primary Material | High-impact ABS/PC blend plastic, UL94 V-0 rated for flame retardancy. |
|---|---|
| Housing Design | Round, ergonomic shape with internal baffles for sound optimization and external mounting lugs. |
| Buzzer Cavity | Integrated, acoustically tuned chamber designed for 25mm-30mm magnetic buzzers (85dB+ output). |
| Dimensions & Weight | Diameter: 95mm, Height: 35mm. Weight: approx. 65 grams (without electronics). |
| Protection Rating | IP54 rated - Dust protected and splash water resistant. |
| Color & Finish | Matte white or black standard (custom colors available), textured finish to resist fingerprints. |
Technical Design & Acoustic Engineering
At the heart of this housing is a meticulously engineered buzzer cavity. Unlike generic enclosures, this cavity is mathematically modeled to act as a Helmholtz resonator in certain frequency ranges, amplifying the buzzer's output by up to 15% while ensuring sound clarity. The round shape minimizes internal acoustic cancellation and allows for 360-degree sound dispersion, critical for alarms that need to be heard from any angle.
The internal structure features ribbing not only for structural rigidity but also to break up standing sound waves. The entrance port for the buzzer is flared to reduce turbulent air noise, ensuring the alarm tone is sharp and penetrating. Material thickness varies strategically: thicker at mounting points (2.5mm) for strength, thinner at the sound emission grille (1.2mm) to reduce attenuation.
Smart Home & IoT Integration
This housing is designed for seamless integration into the modern smart home. Its compact, round form factor is ideal for discrete placement on doors, windows, or glass panels. The design includes dedicated internal channels for routing wires from the vibration sensor PCB to the buzzer, eliminating clutter and potential interference.
Compatibility is a key focus. The housing's internal layout accommodates common microcontroller boards (ESP32, Arduino Nano derivatives) and lithium battery packs. Pre-modeled slots allow for easy snap-in of tamper switches and LED status indicators. The exterior features a concealed reset/pairing button port and a micro-USB cutout for charging, maintaining a clean aesthetic.
For OEMs, the design supports both standalone vibration alarm units and modules that can become part of a larger multi-sensor security device. The plastic blend is RF-friendly, ensuring minimal signal interference for Wi-Fi, Zigbee, or Z-Wave communication modules housed within.
Why Our Housing Outperforms Generic Enclosures
| Feature | Our Design | Standard Enclosure |
|---|---|---|
| Acoustic Output | 85-90dB at 1m, clear & directional | Muffled, often below 80dB |
| Installation | Integrated mounting lugs & alignment pins | Requires additional brackets |
| IP Rating | IP54 (Engineered seals) | Typically IP30 or unrated |
| Internal Organization | Dedicated slots for PCB, battery, buzzer | Empty box, requiring adhesives |
| Aesthetic | Modern, discreet, consumer-electronics grade | Industrial/utilitarian look |
