Description

A New Type of Noise Reduction and Sound Isolation Headphones

technical field

The utility model relates to a novel noise-reducing and sound-insulating earphone, which belongs to the field of earphone devices.

Background technique

The current situation of our country's factories has a lot of unfavorable factors that noise affects workers' work, and for workers who are busy with work, they are more sensitive to the harmful factors that affect their work. Noise is more likely to affect their work and communication, reduce their work efficiency, affect their normal work, and may endanger their health. In order to reduce these impacts, workers began to wear simple earmuffs. This measure can indeed achieve some sound insulation effects, but there are also many defects. For example, simple earmuffs can only play the role of sound insulation. When other people talk to him, he can't hear him. The workers can't achieve a good conversation, which may cause production accidents or misunderstand each other's meaning. . In order to solve these problems, it is necessary to design a new sound-insulating and noise-canceling earphone.

Contents of the invention

The technical purpose of the utility model is to provide a new type of noise-reducing and sound-insulating earphone, so that people working in a noisy environment will not be disturbed by noise, and at the same time, it can enable workers to communicate well.

A new type of noise-reducing and sound-isolating earphones, including right earmuffs, left earmuffs, and connectors, wherein the right earmuffs and left earmuffs have the same structure, and the outer sides of the right earmuffs and left earmuffs are provided with fixing parts, and the two ends of the connectors are Connect the fixture; the feature is: the fixture is fixedly connected to the middle part of the outer surface of the vacuum cover; the longitudinal section of the vacuum cover is an inverted trapezoid, the cavity wall of the vacuum cover is hollow, and the internal configuration is installed in the vacuum cover shell; the internal configuration shell is a hollow shell, and a power supply and a wireless control center are installed inside the internal configuration shell; the side of the internal configuration shell close to the ear is provided with a sponge layer, and a protruding Earplugs, the earplugs are connected to the wireless control center through wires, and the noise-canceling microphone is connected to the right earmuff, and the noise-canceling microphone is connected to the wireless control center.

The earmuffs of the earphones are wrapped by a vacuum cover, which can effectively prevent the noise from being transmitted to the ears through the earmuffs. At the same time, with the function of earplugs, the sound entering the ears is further attenuated; the built-in wireless of the earphones The control center can realize the wireless transmission of sound signals, enabling people wearing the same headset to talk to each other, which is very suitable for people working in noisy environments.

Further, a ferrule is provided on the edge of the vacuum cover close to the ear, and the ferrule is made of sponge. After wearing the earphone, the ferrule can surround the ear, which can further prevent noise from entering the ear.

The beneficial effect of the utility model is that the earphone has the function of sound insulation and noise reduction, which can prevent people working in a noisy environment from being disturbed by noise. Bring convenience.

In the figure, right earmuff 1, left earmuff 2, connecting piece 3, vacuum cover 4, internal configuration shell 5, ferrule 6, earplug 7, fixing piece 8, noise reduction microphone 9, power supply 10, wireless control center 11.

detailed description

The following are preferred implementation modes of the present utility model, but the protection scope of the present utility model is not limited thereby.

As shown in the figure, a new type of noise-reducing and sound-isolating earphone includes a right earmuff 1, a left earmuff 2, and a connecting piece 3, wherein the right earmuff 1 and the left earmuff 2 have the same structure, and the right earmuff 1 and the left earmuff 2 The outer side is provided with a fixing part 8, and the two ends of the connecting part 3 are connected to the fixing part 8; it is characterized in that: the fixing part 8 is fixedly connected to the middle part of the outer side of the vacuum cover 4; the longitudinal section of the vacuum cover 4 is inverted trapezoidal, the cavity wall of the vacuum cover 4 is hollow, and an internal configuration shell 5 is installed in the vacuum cover 4; the internal configuration shell 5 is a hollow shell, and a power supply 10 and a wireless control center 11 are installed inside the internal configuration shell 5 , the wireless control center 11 can realize the transmission of sound signals; the side of the internal configuration shell 5 close to the ear is provided with a sponge layer, and an outwardly protruding earplug 7 is arranged on this surface, and the earplug 7 is connected to the wireless control center 11 through a wire, A noise reduction microphone 9 is connected to the right earmuff 1 , and the noise reduction microphone 9 is connected to a wireless control center 11 .

The earphone has the outer side of the earmuff passing through the vacuum cover 4 and is wrapped by the vacuum cover 4, which can effectively prevent the noise from being transmitted to the ear through the earmuff. At the same time, with the function of the earplug 7, the sound entering the ear is further attenuated; the earphone The built-in wireless control center 11 can realize wireless transmission of sound signals, and can enable people wearing the same headset to communicate with each other, which is very suitable for people working in noisy environments.
