Description
Technical field
The present invention relates to headphone, relate in particular to a kind of be worn on head can be by adjusting earmuff distance to adapt to the headphone that user's head size changes.
Background technology
The version that earphone is commonly used has two kinds, a kind of for directly filling in the earphone that hangs in the external auditory meatus, though the earphone of this kind version is small and exquisite, but because its weight is born by external auditory meatus fully, so long-term use can make external auditory meatus that sense of discomfort is arranged and come off from ear easily, for head it off, designed and worn overhead headphone, this kind earphone comprises headband and is built-in with the earmuff formation of loud speaker and respective audio circuit, headband is suspended on the head during use, earmuff covers on the ear, makes the duct sense of not bearing a heavy burden, and improves the comfortableness when using.But because user's head size is variant, in order to improve the versatility of headphone, even the different user of head size can use the earphone of same dimensions, this just requires the relative position of earmuff and headband adjustable.Be 2008101702909 at the Chinese patent publication number, name is called in the patent documentation of " earphone " and discloses a kind of headphone, this earphone comprises earmuff, is fixed on fixed mount and the headband of earmuff outside, headband is connected with fixed mount by slider, is provided with the elasticity ear pad in the side towards ear of earmuff.The purpose of design flexibility ear pad is in order to alleviate earmuff to the compressing of ear, to improve the comfortableness when using.Slide construction is the tubular structure that more piece is nested together, and the change of relative position is to realize by the insertion length that changes between each adapter between earmuff and the headband.Earphone in this patent has following deficiency: complex structure, because the tubular structure that slider is nested together for the more piece layer, so cross section is thicker, it is clumsy that integral body seems, increase material usage and taken volume, slider thick in the use can cause extruding to head, aesthetic property and comfortableness when influence is worn, when being worn over the position of the last adjustment of head earmuff, hair might snap in the slide construction and be torn off, poor stability, and the elasticity ear pad takes to cover the form on earmuff surface, influence audibility, poor with the soundproof effect in the external world.
Summary of the invention
The invention provides that a kind of outward appearance is succinct, fail safe and comfortableness is good, soundproof effect is good, tonequality the is good adjustable headphone of earmuff distance, the mechanism that has solved the problem of existing headphone lower tone, soundproof effect difference and will regulate the earmuff distance is arranged on outward appearance clumsiness, the poor stability that the earmuff outside causes, the problem that influences comfort.
Above technical problem solves by following technical proposal: the adjustable headphone of a kind of earmuff distance, comprise headband, be arranged on a pair of earmuff at two ends, the headband left and right sides, be arranged on the audio board of earmuff inside, be arranged on the loud speaker of earmuff inside and the lead that the electronic component in a pair of earmuff is electrically connected, described headband is the rubber-like clip, intert in described a pair of earmuff at the two ends, the left and right sides of described headband telescopically respectively, be provided with if this buckling groove in the left and right sides of described headband side faces at both ends, described buckling groove distributes along the bearing of trend of described headband, in described earmuff, be provided with the clamping block that matches with described buckling groove, described clamping block is connected with described earmuff elasticity, is provided with the chute for described headband slip usefulness in described earmuff.The method of regulating the distance of earmuff is, realize by the degree of depth that changes headband two ends insertion earmuff, fixing being stuck in the buckling groove by clamping block between headband and the earmuff realized, owing to be connected for elasticity between clamping block and the earmuff, when making headband do Plug Action with respect to earmuff, can slide relatively between snap groove and the clamping block, but clamping block is attached on the buckling groove all the time, the mode of flexible clamping in use, can keep good clamping dynamics always, headband is designed to rubber-like and can binds round, can be clamped in user's head automatically, the design chute cooperates slide block to slide, and convenience and headband are difficult for rocking during slip.
As preferably, described clamping block is provided with elasticity and connects neck, described clamping block connects neck by described elasticity and is connected with described earmuff phase elasticity, and described elasticity connects neck and described clamping block is structure as a whole, and described elasticity connects neck and is fixed on the described earmuff by screw.Directly design is connected neck and realizes that clamping block is connected with elasticity between the earmuff with elasticity that clamping block is structure as a whole, and simple in structure, parts are few, elasticity connects neck and is connected by screw with earmuff, when clamping block or the damage of elasticity connection neck, can change separately, maintenance cost is low.
Preferred as another, be provided with spacing hole in the described earmuff, be provided with the spring that clamping block is connected with earmuff elasticity between described spacing hole and the described clamping block, described spring one end is welded on the described clamping block, and the other end of described spring wears and is connected in the described spacing hole.Realize that by spring clamping block is connected with elasticity between the earmuff, good springiness, the elastic force controlled amount is good, and spring is welded on the clamping block, and connected mode is simply used, it is little to take up room, design spacing hole between spring and the earmuff and fix spring by this spacing hole, the spring difficult drop-off is convenient to clamping block is taken off in earmuff simultaneously, convenient for installation and maintenance, maintenance cost is low.
As preferably, described earmuff is provided with the jack that passes for described headband, be matched in clearance between described jack and the described headband, the distance of the outer face of the described jack of described clamping block distance is greater than the distance between two buckling grooves of head and the tail in described several buckling grooves.Be designed to matched in clearance between the jack on headband and the earmuff, laborsaving during adjustment, when using, children and women's user can not feel effort yet, hommization degree height, the distance of the outer face of the described jack of clamping block distance is greater than the distance between two buckling grooves of head and the tail in described several buckling grooves, in the use, earmuff is during apart from maximum, clamping block is connected in that buckling groove of least significant end, make the snap groove on the headband be positioned at earmuff inside all the time, hold headband when earmuff plugs, the bad snap groove that touches of hand, comfortableness and fail safe are good.
