Abstract

The utility model discloses a sharing earplug, which comprises a plug which is inserted with an audio-visual apparatus, a mother earplug and a son earplug which are provided with loudspeakers and connected with the plug after connected in parallel. The utility model is characterized in that the position of connected in parallel of the mother earplug and the son earplug is provided with a matcher which comprises a plurality of jacks and adjusting knobs, wherein, the adjusting knobs comprise volume adjustment and tone quality adjustment, and likewise, a conducting wire of the son earplug is also provided with an adjustor for volume adjustment and tone quality adjustment; the inner parts of the mother earplug and the son earplug which are provided with the loudspeakers are provided with noise monitors. The utility model can realize volume adjustment and tone quality adjustment, and can also ensure load matching. The sharing earplug can achieve optimal listening effect. The noise monitors can cause the noise received by the sharing earplug to follow the principle of no damage to hearing. When the noise is exceeded, loudspeaker circuits can be cut automatically by circuit feedback, and the hearing can be protected.

Description

Can shared earplug

Technical field

The utility model relates to a kind of walkman earplug, especially can be simultaneously for two people or listen the earplug of an audio-visual apparatus more than two people altogether.

Background technology

The walkman earplug is to watch the electronic components of usefulness such as TV, music appreciating, online when supplying people for amusement, common earplug has only an auricular appendage plug, only use for a people, it can avoid the interference of sound to others, particularly child does one's assignment in the family, for not being subjected to father and mother to see TV, the influence of listening to the music, just more need earplug.But common earplug has only a secondary chock plug, only uses for a people, if two people think to listen to simultaneously, then can only respectively use wherein one, just is without access to the effect of three-dimensional dual track." Earphone for two-persons " of Chinese patent CN2337733y for people provide can the shared earplug of two people, its divides main plug and secondary plug two parts, secondary plug inserts the jack of main plug, is connected main chock plug and secondary chock plug respectively by main plug line and secondary plug line, supplies double shared.But the load of electrical equipment such as recorder generally will be mated, when the group earplug inserts, because the resistance decreasing of load, therefore do not match and do not reach best audibility, the hearing impairment that also exists the danger of noise to hearing impairment, particularly teenager to cause when noise is big can't recover.

Summary of the invention

Technical problem to be solved in the utility model be to avoid the defective of prior art and provide a kind of audibility good, that do not have hearing impairment, can many people listen to can shared earplug.

Technical problem of the present utility model realizes by following technical proposal: can shared earplug, it comprises the plug that plugs with audio-visual apparatus, the mutual parallel connection that links to each other with plug also has the female earplug and the sub-earplug of loud speaker, it is characterized in that described female earplug, sub-earplug place in parallel are provided with the adaptation that contains a plurality of jacks and adjusting knob.

Described adaptation adjusting knob comprises volume adjustment knob and tonequality adjusting knob.

The connection line of described sub-earplug and adaptation is provided with the adjuster of band volume adjustment knob and tonequality adjusting knob.

Also be provided with noise monitor in described female earplug that has a loud speaker and the sub-earplug.

Compared with prior art, the utility model one or more sub-earplugs of can pegging graft all can be enjoyed the effect of three-dimensional dual track; The band volume is regulated, the adaptation of tonequality adjusting knob owing to be provided with on connection line, can also guarantee load matched, reaches best audibility; Have in female earplug of loud speaker, the sub-earplug and be provided with noise monitor; when the earplug noise excessive; when reaching 90 decibels of hearing to the people and causing the damage that can not repair, noise monitor can cut off speaker circuit automatically by the circuit feedback, thereby reaches the purpose of protection hearing.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

In conjunction with above-mentioned accompanying drawing embodiment the utility model is further specified again:

Can comprise the plug 1 that plugs with audio-visual apparatus (as videocorder, broadcast receiver, television set, CD, multimedia computer or the like) by shared earplug (referring to Fig. 1), this plug links to each other with female earplug 7 by lead, on both connection leads, be provided with adaptation 2, reaching load matched, thereby obtain better audibility.A plurality of jacks 8 are arranged on the adaptation, and a plurality of sub-earplugs 6 of can pegging graft form the structure of sharing an audio-visual apparatus that female earplug and sub-earplug are in parallel.Except jack, also be provided with volume adjustment knob 4 and tonequality adjusting knob 5 on the adaptation, these knobs can be regulated volume, tonequality quality respectively, to reach best audibility.

Sub-earplug 6 is pegged graft by the jack on the adaptation 28, is provided with the adjuster 3 of band volume adjustment knob 4 and tonequality adjusting knob 5 on connection line equally.

Simultaneously in having female earplug 7 of loud speaker, sub-earplug 6, the noise monitor (not shown) is set; noise from audio-visual apparatus is monitored; when its noise reaches 90 decibels; because of extremely unfavorable to people's ear hearing; might cause the damage that to repair; noise monitor will cut off speaker circuit automatically by the circuit feedback, and people's ear hearing is protected.
