Embodiment 1

[0037] like figure 1 As shown, a head-mounted noise reduction earmuff includes an elastic headband 6, and the two ends of the elastic headband 6 are provided with an earmuff main body. The elastic headband 6 provides pressure to make the earmuff bodies at both ends close to each other.

[0038] The main body of the earmuffs connected at both ends is as figure 2 As shown, it includes a first shell 1, a second shell 2, a soundproof body 3, and a connecting wire 4, and the soundproof body 3 is arranged between the first shell 1 and the second shell 2;

[0039] like image 3 As shown, the first housing 1 is provided with a sound receiving device, a sound wave signal conversion module, and a volume control module, and the second housing 2 is provided with an electrical signal conversion module and a sound output module;

[0040] The sound receiving device is used for collecting environmental sound wave signals;

[0041] The sound wave signal conversion signal module is connect...

Embodiment 2

[0058] This embodiment provides an in-ear earplug, the specific structure is as follows: Figure 6 As shown, it includes a first shell 1, a second shell 2, a sound-insulating body 3, and a connecting wire 4. The sound-insulating body 3 is arranged between the first shell 1 and the second shell 2; the sound-insulating body 3 It is an in-ear earplug made of slow-rebound sound-insulating material, the second shell 2 is embedded in one end of the sound-insulating body 3 , and the first shell 1 is connected to the other end of the sound-insulating body 3 .

[0059] Such as image 3 As shown, the first housing 1 is provided with a sound receiving device, a sound wave signal conversion module, and a volume control module, and the second housing 2 is provided with an electrical signal conversion module and a sound output module;

[0060] The sound receiving device is used for collecting environmental sound wave signals;

[0061] The sound wave signal conversion signal module is conn...

Embodiment 3

[0070] In this embodiment, a storage module is added in the first housing 1 in Embodiment 1 or Embodiment 2, and a current signal carrying an audio signal in a dangerous environment is stored;

[0071] The processor is connected with the storage module, the sound wave signal conversion module, and the sound output module, and the current signal carrying the environmental audio signal output by the sound wave signal conversion module and the current signal carrying the dangerous environment audio signal in the storage module For comparison, it is judged that the current signal carrying the environmental audio signal output by the sound wave signal conversion module is a dangerous signal, and then the current signal with the warning audio signal is output to the sound output module.

[0072] The processor here refers to a microprocessor with calculation, analysis and judgment functions, such as an ARM microprocessor.

[0073] In embodiment 1, the judgment of danger depends on th...

Abstract

The invention relates to an adjustable decibel noise reduction device, which also includes a first shell, a second shell, a sound-insulating body, and connecting wires, and the sound-insulating body is arranged between the first shell and the second shell; the sound receiving device , the sound wave signal conversion signal module, the volume control module are arranged in the first casing, the sound output module is arranged in the second casing, and the current signal carrying the environmental audio signal output by the volume control module is sent to the In the sound output module; the sound insulation body is provided with a first through hole for connecting wires to pass through. Realize sound insulation and noise reduction through the sound insulation main body, through the sound receiving device in the first casing, the sound wave signal conversion signal module volume control module, the volume of the environmental audio signal can be input into the second casing with a selectable size and output through the sound output module, use The user can adjust the volume of the received ambient sound according to their own situation, that is, it will not affect themselves, and they can maintain proper vigilance to the environment.

Description

technical field [0001] The invention relates to an adjustable decibel noise reduction device. Background technique [0002] In areas such as production workshops and construction sites, there are usually a lot of noisy and high-decibel ambient sounds. People who work in such an environment with a lot of noisy and high-decibel ambient sounds are likely to cause psychological and even physical damage. At present, there are sound insulation devices with excellent noise prevention effect on the market, such as sound insulation earmuffs, sound insulation earplugs, etc., which can be used for noise reduction and sound insulation. Then it is precisely because the noise reduction effect is too good, it is easy for personnel to miss some dangerous signals that can be judged by sound, so that when an accident occurs, personnel cannot detect and escape in time. Contents of the invention [0003] The purpose of the present invention is to provide an adjustable decibel noise reduction...
