Abstract
The utility model relates to a semi-conductive health-care earplug used for radio-receiver recorders, and miniature record players. The utility model comprises a loudspeaker 1, a conducting wire 2, a plug 3, and an ear support 4 arranged on the back side of the earplug loudspeaker. When using, the ear support is inserted into the ear, the loudspeaker is faced outside, and thus acoustic waves are avoided directly transmitting into a middle ear and an inner ear through an external auditory canal and are avoided stimulating an auditory organ pipe to generate a feeling of indisposition. Compared with ordinary earplugs, the hearing fatigue generated by the health-care earplug can be ignored, and thus, the health-care earplug has the effect of health care.
Description
The utility model relates to a kind of health-care earphone that is used for radio-cassette player, miniature walkman and transistor radio.
When at present popular on the market common earplug uses earplug is inserted in the ear, support by auricle, because loud speaker is just facing in the ear, when listening to, sound wave stimulates big to sense of hearing organ pipe, the sense of hearing is uncomfortable, very easily produces hearing fatigue, long-term use is influential to hearing ability, and existing China Patent No. is CN2094840
, CN2090136 μ, CN2094166 μ patent, make the loud speaker front of common earplug outside ear, carry out some improvement, but structure more complicated is all carried inconvenience.
The purpose of this utility model is to provide a kind of health-care earphone, uses when long that the sense of hearing is comfortable, hearing is without prejudice.
The utility model adopts such technical scheme to realize its purpose: the back side at the loud speaker of earplug is stained with an ear holder with adhesive, this ear holder is made by circular piece outsourcing one deck foam or flannelette, the circular piece radius R is 3mm--10mm, thickness H is 4mm--8mm, during use the ear holder is inserted in the auricle, loud speaker just faces outside the ear.
When the utility model is used for audition, because earplug loudspeaker direction (and not towards earhole) has outwardly avoided sound wave directly to import middle ear, inner ear into through external auditory meatus, sound wave obtain auricle collection, adjust after, little to acoustic stimuli, be difficult for producing auditory fatigue, thereby have health-care effect.
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail:
Fig. 1 is common earplug
Fig. 2 is the utility model " health-care earphone "
Health-care earphone shown in Figure 2 is a kind of embodiment of the present utility model, and it is made of loud speaker 1, lead 2, connector 3, ear holder 4.The ear holder is made by the thin foam of plastics disk outsourcing one deck, and plastics wafer radius R=6mm, thick H=6mm are bonded in the loud speaker back side with the epoxy resin adhesive with the ear holder and form.
