AI Technical Summary

⚠Technical Problem

Existing miniature receivers lack acoustic path control, making them prone to standing wave coupling at specific frequencies. This can lead to air column resonance and high-frequency howling, affecting sound quality and interference resistance.

⚗Method used

It adopts noise reduction components and S-shaped sound guide channel design. The noise reduction cotton cover physically blocks and absorbs external noise, and the S-shaped sound guide channel disperses the sound wave path. Combined with the design of the guide frame and sound guide block, it weakens standing wave coupling, reduces air column resonance, and improves sound clarity and sound quality stability.

🎯Benefits of technology

It effectively suppresses high-frequency howling, improves radio clarity and sound quality stability, enhances anti-interference capabilities, and ensures the accuracy of signal output and the stability of the diaphragm.

Abstract

This utility model relates to the field of receiver technology, specifically a noise reduction and optimized packaging structure for a miniature receiver. It includes a packaging shell with an electronic board fixedly mounted on one side; and a noise-reducing radio mechanism for improving the receiver's reception performance. The noise-reducing radio mechanism includes a noise-reducing cotton sleeve fixedly mounted on one side of the packaging shell. A noise-reducing component is disposed on one side of the packaging shell, and a radio receiving component is disposed inside the packaging shell. The noise-reducing component guides external sound waves into the radio receiving component, while the noise-reducing cotton sleeve physically blocks and absorbs external environmental noise. The noise-reducing component employs an S-shaped sound guide channel, which effectively disperses the sound wave propagation path, weakens standing wave coupling, and reduces the risk of air column resonance, thereby suppressing high-frequency howling and improving reception clarity and sound quality stability.
