Description

Hearing loss prevention headset {THE PROTECTION HEADSET OF DIFFICULTY IN HEARING}

The present invention is a hearing loss prevention headset that can manage the machine by listening to the sound of the surrounding machinery while protecting the hearing loss in a high noise workplace, wearing a hearing loss prevention headset ear plugs attached to one side of the bone conduction speaker 150 ( Insert the 110 into the ear to block the ear hole, the bone conduction speaker 150 is located next to the ear, the ambient sound or mechanical sound detected by the microphone 210 of the main body 200 MCU (350) and automatic volume control unit 330 and the power amplifier 340 to amplify the sound of the appropriate size to hear through the bone conduction speaker 150, because the ear is closed no matter how loud noise, ear plug 110 is blocking the eardrum It is prevented, and even if the ear is closed, the bone vibration of the bone conduction speaker 150 allows the user to hear the surrounding sounds or the sound of the mechanical equipment. It relates to the prevention of hearing loss headset capable.

The registered hearing aid No. 10-0742979 includes the main body 1 and a speaker 2 connected to the main body 1. The main body 1 includes a microphone 3, an electric wire switch 4, and a volume adjusting unit 5. The speaker cable connection terminal 6 is provided in the side surface of the main body 1, Preferably, the audio cable connection terminal 7 is provided.

The speaker 2 includes an electrostatic speaker 8, a ridge 9 protruding from one side thereof, and a cable 10, and the connector 11 of the cable 10 is connected to the main body 1. It plugs into the speaker cable connection terminal 6 and connects to the main body part 1. The other end of the audio cable connected to the audio cable connection terminal 7 is configured to be connected to the audio output terminal of the sound output device.

By the way, the hearing aid used in the present invention uses a bone conduction speaker, but by simply amplifying the surrounding sound and listening to the bone conduction speaker attached to the headset, if the ambient sound is too loud, the sound of the bone conduction speaker is heard.

Because of this, when a loud noise occurs in the surroundings, too loud sounds are heard by the bone conduction speaker, which is a problem that is amazed. Hearing aids are simply devices that amplify less sound and make it louder.

The problem to be solved by the present invention is that in the workplace with a loud noise or intermittent large impact noise, the workers to the ear plug 110 to protect the hearing loss.

Hear the operation sound of the machine equipment to manage while maintaining the machine, and prevent the hearing loss due to the impact noise while listening to the voice of the person next to the ear while blocking the ear, loud noise, machine equipment sound or impact noise occurs Even if the sound is reduced by converting it into a sound of appropriate size so that it can be heard through the bone conduction speaker 150, workers can safely listen to and prevent hearing loss, listen to mechanical equipment sounds, and have a conversation even in the poor environment. The main purpose is to provide a hearing loss prevention headset that can be.

The present invention was made in view of the above problems to prevent hearing loss by attaching an earplug 110 to one side of the bone conduction speaker 150 attached to the hearing loss prevention headset to prevent hearing loss, The microphone 210 built into the main body 200 detects a surrounding voice or a mechanical equipment sound, amplifies the microphone detection signal by the microphone amplifier 310, and detects the amplified signal by the signal detector 320. The size of the signal is selected by the MCU 350 and the automatic volume control unit 330 is controlled according to the size of the selected signal to control a signal having an appropriate size to be input to the power amplifier 340, and the power amplifier 340. Amplified to a size that the bone conduction speaker 150 can vibrate to vibrate the bone conduction speaker 150 so that the user can always hear the proper sound regardless of the size of the surrounding sound to prevent hearing loss and other mechanical sound It is to be able to hear human voices.

That is, when the ambient noise is large, the signal detected by the signal detector 320 is detected by the MCU 350 to control the automatic volume controller 330 to appropriately reduce the signal size, and when the ambient sound is small, the signal detector 320 is reduced. ) By detecting the signal detected by the MCU 350 to control the automatic volume control unit 330 to increase the signal size so that the sound heard by the bone conduction speaker 150 is always appropriate.

Regardless of the amount of ambient noise or the sound of mechanical equipment, the earplugs 110 cover the ears to prevent hearing loss, and the bone conduction speaker 150 is always at a constant sound level by automatic control of the MCU 350 and the automatic volume control unit 330. It is to provide a hearing loss prevention headset that can be heard through.

The present invention can ensure the prevention of hearing loss by blocking the ear hole with the ear plug 110 in the workplace with a lot of noise or intermittent loud noise, and always sound the machine sound with a constant sound regardless of the magnitude of the ambient noise Hearing loss prevention headset for machine management while listening to wearing helmets and hats, wearing masks, and preventing hearing loss and mechanical equipment for workers working in airfields or in noisy ironworks, printing shops, thermal power plants, and nuclear power plants It is a very useful invention that can manage the machinery while directly listening to the sound of.
