Description

Technical Field

[0001] This utility model belongs to the technical field of noise detection equipment, and in particular, a portable noise detection device. Background Technology

[0002] Noise detection refers to the process of measuring and analyzing parameters such as the intensity (decibels), frequency distribution, and duration of sound in the environment using specialized equipment or techniques. Its core purpose is to assess the potential impact of noise on human health, the living environment, or industrial production, and to provide a scientific basis for noise control, regulatory enforcement, or equipment optimization. Noise detection quantifies the degree of noise pollution, providing data support for developing noise reduction measures (such as sound barriers and equipment upgrades).

[0003] In recent years, with the increasing demand for environmental monitoring, noise detection equipment has gradually developed towards miniaturization and portability. In the existing technology, most portable noise detection devices on the market have achieved lightweight design (generally weighing less than 300g) by simplifying the structure and integrating sensors and microcircuits. They can be held in the hand or put in a pocket and are suitable for rapid detection in outdoor mobile scenarios.

[0004] However, such devices still have significant drawbacks in practical use: high risk of accidental activation. To maximize ease of operation, function buttons (such as power on / off and mode switching buttons) are typically located on the side or top of the device. When users place the device in confined spaces like pockets or backpacks, these buttons are easily triggered accidentally due to body movement or external pressure. Therefore, effectively addressing the issue of accidental button activation while maintaining device miniaturization has become a critical technical challenge for portable noise detection devices.

[0005] The purpose of this invention is to provide a portable noise detection device to solve the problems mentioned in the background art. Utility Model Content
