Painful pressed and stivy feel can not be generated by wearing and using the utility model for a long time, and the utility model is the headband type earphone which is comfortable to wear, protects ears, has favorable listening effect and is convenient and durable.

Description

A kind of headphone with breathing ear cushion

Technical field

The utility model relates to a kind of electric equipment products, and particularly a kind of headphone with breathing ear cushion belongs to the electro-acoustic product technical field.

Background technology

Along with the progress in epoch, what electroacoustic techniques was used popularizes, and the use of earphone is more and more general, and the sound machine of existing single auditory function also has the earphone of can audibility singing of subsidiary microphone.Present popular on the market common headphones, generally all constitute with rigid plastics or elastomeric material, owing to be hard material, ear was uncomfortable when people wore, wear for a long time the ear distending pain and influenced hearing, for improving the uncomfortable sensation of " firmly " like this, someone wraps a layer foam cover on earphone, this is improved the performance of earphone, and tentatively improved and worn uncomfortable sensation, but because foam material itself is airtight, be not durable and poor sealing, tonequality is leaked easily, influence audibility, and earphone has been worn of long duration still to feel ill.

Summary of the invention

For overcoming above-mentioned technological deficiency; the purpose of this utility model is to provide a kind of headphone with breathing ear cushion, this earphone configuration breathing ear cushion, novel structure; wear comfortable, nice and cool durable environmentally-friendly sanitary again, protection hearing, thereby reach good audibility.

The utility model is achieved through the following technical solutions:

A kind of headphone with breathing ear cushion, comprise housing, loudspeaker, loudspeaker base plate, headband, connection handle, loudspeaker are fixed on the loudspeaker base plate, the loudspeaker base plate is fixed in the housing, and miaow arm and miaow head are set on the earphone-housing of the left and right sides, and the connection handle on the housing couples together the right and left earphone by headband, configuration ring-type ear pad on its base plate, be provided with groove and chimb on base plate, groove and chimb form the screens of snapping, and ear pad snaps onto in the groove screens on the base plate by trim ring.Described ear pad is a ring-type hollow flexible glue circle, and its one side of pressing close to ear has little round mouth, and the diameter of round mouth is corresponding with the diameter of loudspeaker cone, and its bottom surface that snaps onto base plate has big round mouth, and the diameter of big round mouth is corresponding with base plate upper groove diameter.Trim ring is the hard circle, and its diameter is corresponding with base plate upper groove diameter; The opening diameter of a circle that trim ring internal diameter and ear pad are big is identical, and the trim ring that is enclosed within like this in the cushion rubber just can snap onto ear pad in the groove of base plate exactly.

Described ear pad is with not having the silica gel material of toxicity or thermoplastic elastomer (TPE) TPR material to make.Described ear pad is except that being that also useful thermoplastic elastic material is made solid ring-type ear pad the ring-type flexible glue circle of hollow, and promptly whole ring-type ear pad is a thermoplastic elastomer (TPE) TPR material.Thermoplastic elastomer (TPE) TPR is a kind of plasticity composite material, has soft sense of touch and stable rerum natura, and is harmless to the human body contact.

The effect that the utility model is useful: compare with headphone in the past, the utlity model has following advantage:

1, ventilative, nice and cool.Ear pad adopts soft silica gel or thermoplastic elastic material to make, and this class material non-toxic, good stability do not have injury to human body; and has close skin sense; earphone can not produce the tenderness sense yet when wearing for a long time, also have ventilative, feel cool, and the effect of protection ear is arranged.

2, environmental protection, health, durable.This earphone ear pad adopts harmless material to make, and service time, length can not play chemical change yet, and anti ageing property is good, has prolonged the useful life of earphone,

3, improve earphone tonequality.Owing to adopt novel ear pad structure, good airproof performance is worn comfortablely, can promote tonequality, improves audibility.

Embodiment

The contrast accompanying drawing describes in detail

As Fig. 1-shown in Figure 6, a kind of headphone with breathing ear cushion, comprise earphone case 1, connection handle 2, loudspeaker 3, loudspeaker base plate 5, headband 4, loudspeaker 3 are fixed on the seat board 5, the seat board 5 that loudspeaker 3 are housed is fixed in the earphone case 1, and the connection handle 2 on the housing 1 couples together the right and left earphone by headband 4.Ring-type ear pad 8 is set on earphone base plate 5, is provided with groove 6 and chimb 7 on base plate 5, groove 6 and chimb 7 forms the screens of snappings, and ear pad 8 snaps onto in groove 6 screens on the base plate 5 by trim ring 10.Ear pad 8 is a ring-type hollow flexible glue circle, and its one side of pressing close to ear has little round mouth, and the diameter of round mouth is corresponding with the diameter of loudspeaker 3 cones, and its bottom surface that snaps onto base plate 5 has bigger round mouth, the sizableness of the diameter of round mouth and base plate upper groove 6.Ear pad 8 just, two round mouth planes of bottom surface not on same horizontal plane, promptly ear pad only has a round edge to be connected with base plate, another round edge is unsettled, makes the certain space length of maintenance between ear pad cushion rubber main part and base plate, and is ventilative when being convenient to earphone and wearing.Ear pad 8 usefulness do not have the silica gel material of toxicity or are made by thermoplastic elastomer (TPE) TPR material.This earphone ear pad is except that being the ring-type cushion rubber of hollow, and also useful thermoplastic elastic material is made solid ring-type ear pad.

This earphone is placed in the base plate 5 that is fixed with loudspeaker 3 in the earphone case 1 when mounted, and with screw base plate 5 is tightened in the housing 1, puts into the trim ring 10 of rigid plastics then and the screens of aiming on the base plate is pressed in ear pad 8.Because the size and the trim ring diameter of groove match, like this trim ring together with ear pad just securely fastening on the base plate of earphone, adopt that human body is had the nontoxic durable material silica gel of close skin sense or ventilative nice and cool ear pad that thermoplastic elastomer (TPE) TPR makes is important improvement to the earphone hommization.
