Abstract
The utility model relates to an audio-video device, especially an earphone capable of displaying a db value. The utility model aims to provide an earphone capable of knowing whether the volume of the earphone is within a safe scope or not at any time. The earphone capable of displaying db value comprises a receiver, the inner portion of the receiver is provided with a sound sensor, the outer surface is provided with a display screen and a volume adjuster, and the sound sensor is connected to the display screen through a lead. The induction scope of the sound sensor is 0 to 120 dbs. The sound sensor converts a sound into an electric signal, the electric signal is transmitted to the display screen, and a control unit arranged in the display screen converts the electric signal into a digital signal for display. The earphone has the advantages of simple structure, practicality, convenience and being capable of effectively avoiding invisible damage caused by overlarge volume.
Description
Technical field
The utility model relates to a kind of audio-visual equipment, particularly a kind of earphone that shows decibel numerical value.
Background technology
Investigation shows, long-time with the volume that surpasses certain decibel, can cause certain infringement to people's ear, severe patient can cause hearing progressively to descend, and our used earphone all is to regulate volume with transmitting gear at present, though convenient, many times the user if things go on like this will give the healthy very big hidden danger of bringing in order to pursue too high not the knowing of audio effect with the volume accent.Noise pollution not only can influence people's hearing, and can cause hypertension, heart disease, be losing one's memory, absent minded and other psychosyndromes.Studies show that, the highest volume that can accept 30 decibels of people's sense of hearing, when lasting noise surpassed 30 decibels, people's ortho will be interfered, and continued to live in the noisy environment more than 70 decibels people's hearing and healthy will being affected.Up-to-date scientific research confirms, the eyes that noise also can harm people cause that asthenopia and eyesight weaken.When noise intensity during, there is half people pupil can occur approximately and amplifies blurred vision at 90 decibels; When noise reached or surpass 110 decibels, almost all people's eyeball all had weakening in various degree to the adaptation of brightness.Excessive for fear of earpiece volume to hearing and healthy harm, need a kind of earphone that can learn the earpiece volume safe range at any time.
The utility model content
The utility model is intended to propose a kind of earpiece volume of can learning at any time whether at the earphone of safe range.
The technical solution of the utility model is: a kind of earphone that shows decibel numerical value, comprise receiver, and described receiver inside is provided with sound transducer, and outer surface is provided with display screen and volume adjuster, and described sound transducer links to each other with display screen by lead.
The induction range of described sound transducer is 0-120 decibels.
Described sound transducer is converted to the signal of telecommunication with voice signal, is delivered to display screen by lead, and the built-in control unit of display screen is that digital signal shows with electrical signal conversion.
The division rank of sound decibel number: 0-20 decibels: very quiet, almost imperceptible; 20-40 decibels: quiet, just as endless chatter softly; 40-60 decibels: general room is talked; 60-70 decibels: make a lot of noise, diminish nerve; 70-90 decibels: very noisy, nerve cell is damaged; 90-100 decibels: make a lot of noise aggravation, impaired hearing; 100-120 decibels: be difficult to stand, stay and promptly temporarily caused deaf in one minute.
The beneficial effects of the utility model are: simple in structure, practical and convenient, can avoid the excessive stealth injury that brings of earpiece volume effectively.

Fig. 2 is the cutaway view of receiver in the utility model.
Wherein, 1, receiver, 2, volume adjuster, 3, display screen, 4, sound transducer, 5, lead.
Embodiment
Below in conjunction with accompanying drawing is to specify the utility model.
Participate in Fig. 1 and Fig. 2, the utility model comprises receiver 1, and described receiver 1 inside is provided with sound transducer 4, and outer surface is provided with display screen 3 and volume adjuster 2, and described sound transducer 4 links to each other with display screen 3 by lead 5.The induction range of described sound transducer 4 is 0-120 decibels.
During use, sound transducer 4 is converted to the signal of telecommunication with the voice signal of sensing, and is delivered to display screen 3 by lead 5, and display screen 3 built-in control units are that digital signal shows with electrical signal conversion.Division rank according to sound decibel number: 0-20 decibels: very quiet, almost imperceptible; 20-40 decibels: quiet, just as endless chatter softly; 40-60 decibels: general room is talked; 60-70 decibels: make a lot of noise, diminish nerve; 70-90 decibels: very noisy, nerve cell is damaged; 90-100 decibels: make a lot of noise aggravation, impaired hearing; 100-120 decibels: be difficult to stand, stay and promptly temporarily caused deafly in one minute, suitably select volumes by volume adjuster 2.
