Embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
See also Fig. 1, be the structural representation of the utility model specific embodiment double-tone chamber earphone.As described in Figure 1, two earphone bodies 1 and head hoop assembly 2 about this double-tone chamber earphone comprises, about two earphone bodies 1 be connected with head hoop assembly 2 twistings.The length of head hoop assembly 2 is adjustable and have certain elasticity, therefore can left and right sides earphone body 1 be adjusted to suitable position according to the size of different user head.
See also Fig. 2, be the sectional view of earphone body 1 in the earphone of the utility model specific embodiment double-tone chamber.As shown in Figure 2, this earphone body 1 comprises support arm 101, protecgulum 102, leather sheath 103, inner support 105, loudspeaker 106, inserted block (do not mark among Fig. 2, see also Fig. 4 and Fig. 5), printed circuit board (PCB) 110, noise reduction microphone 111 and leather packing 112.
Protecgulum 102 is provided with the groove of spiral outside protrusion together, is called tuning groove 108 (do not mark among Fig. 2, see also Fig. 3).The top of inner support 105 is provided with circular open, is called path 10 9.Tuning groove 108 communicates by path 10 9 and preceding sound chamber 107, has therefore increased the volume in preceding sound chamber 107, thereby has further strengthened the expressive force of earphone to high pitch middle pitch bass, especially supper bass.The shape of tuning groove 108 is not limited to spirality, also can be other shapes, for example linear pattern, broken line type or annular.The utility model specific embodiment is taked spirality tuning groove 108, the loss of gas in the sound chamber 107 before can effectively reducing, thereby it is effectively control gas flow in the tuning groove 108, can make the user experience the difference of high pitch middle pitch bass, and also more attractive in appearance.The shape of path 10 9 is not limited to circle, also can be other shapes, for example rectangle, triangle or irregularly shaped.The utility model specific embodiment is taked circular channel 109, helps passing through of gas.
Tuning groove 108 1 ends are called top at the center of spiral: the other end is called end on the border of spiral.The top of tuning groove 108 and path 10 9 alignment, the end of tuning groove 108 is provided with the opening of rectangle, thereby preceding sound chamber 107 can communicate by the opening and the outside air of tuning groove 108.Opening part also is provided with the dismountable solid inserted block suitable with opening shape, and when solid inserted block occlusion of openings, preceding sound chamber 107 outside air of just getting along well communicates.Of the present utility model another created the design that point just is opening and solid inserted block, can allow the user select supper bass effect or general effect: with solid inserted block occlusion of openings, preceding sound chamber 107 does not communicate with outside air, it is the sound chamber of a sealing, former and later two sound chambeies are arranged this moment, thereby the shock effect expressive force of supper bass is strengthened; Solid inserted block is extracted, and preceding sound chamber 107 communicates with outside air, and in fact have only 104 these sound chambeies, back sound chamber this moment, thereby can show common sound effect.In order to allow the user between supper bass effect and general effect, have the selection of more compromises, except designing above-mentioned solid inserted block, also design multiple hollow inserted block.Please, be respectively the front view and the vertical view of the utility model specific embodiment double-tone chamber earphone hollow core inserted block in conjunction with consulting Fig. 4 and Fig. 5.Hollow inserted block is provided with the manhole of at least one hollow, has designed a plurality of hollow inserted blocks in the present embodiment, and the aperture of through hole is 3.0mm to 4.0mm.The result of broadcast of earphone was best when wherein, the aperture of through hole was 3.6mm.The quantity of through hole is few more, and the aperture of through hole is more little, and the sealing in preceding sound chamber 107 is good more, the sound effect that earphone is play is more near the supper bass effect, otherwise the quantity of through hole is many more, the aperture of through hole is big more, and the sealing in preceding sound chamber 107 is poor more, and the sound effect that earphone is play is more near general effect.The user can be according to self needs, and the hollow inserted block of selecting solid inserted block or having the different apertures of a varying number through hole is regulated, to reach satisfied sound effect.The utility model specific embodiment is at the opening of tuning groove 108 terminal opened rounds, the shape of corresponding inserted block cross section also is circular, but the shape of opening and inserted block cross section is not limited to circle, also can be other shapes, for example rectangle, triangle or irregularly shaped.The utility model specific embodiment has manhole on inserted block, but the shape of through hole also is not limited to circle, also can be other shapes, for example rectangle, triangle or irregularly shaped.Actual conditions can be tested according to the demand to sound effect, thereby determine the shape of opening, inserted block and through hole.
Can also replace solid inserted block or hollow inserted block to be inserted in the opening of tuning groove 108 ends with the adjustable sound paper of different densities: the density of adjustable sound paper is big more, the sealing in preceding sound chamber 107 is good more, the sound effect that earphone is play is more near the supper bass effect, otherwise, the density of adjustable sound paper is more little, the sealing in preceding sound chamber 107 is poor more, and the sound effect that earphone is play is more near general effect.
Printed circuit board (PCB) 110 links to each other with noise reduction microphone 111, and printed circuit board (PCB) 110 is arranged between support arm 101 and the inner support 105, and noise reduction microphone 111 is arranged between support arm 101 and the leather sheath 103.Printed circuit board (PCB) 110 control noise reduction microphones 111 processing audio signal, effectively the filtering ambient noise improves signal to noise ratio, makes the user not hear the sound that earphone is play in the environment of ambient noise is arranged.Noise reduction microphone 111 is arranged on the centre position on the leather sheath 103 in the utility model specific embodiment, helps the equality strength ground filtering earphone ambient noise of all directions all around.The utility model is not limited to centre position on leather sheath 103 to the Position Design of noise reduction microphone 111, also can be arranged on other positions on the leather sheath 103, just design is on other positions, the filtration result of noise is stronger to external world can to cause some direction, some direction to external world noise filtration result a little less than, thereby with noise reduction microphone 111 centre positions of design on leather sheath 103, the effect optimum of filtering ambient noise.
The utility model also has one to create the volumetric ratio that point is to determine preceding sound chamber 107 and sound chamber, back 104, advanced to calculate and test,
See also Fig. 3, be the decomposition texture schematic diagram of earphone body 1 in the earphone of the utility model specific embodiment double-tone chamber.As shown in Figure 3, be followed successively by protecgulum 102, inner support 105, support arm 101 the first half, loudspeaker 106, support arm 101 the latter halfs, noise reduction microphone 111 and leather sheath 103 from top to bottom.As to the replenishing of Fig. 2, Fig. 3 can reflect clear and intuitively that the structure of the utility model specific embodiment double-tone chamber earphone forms, and just is not described in detail the structure of this earphone herein.
Though the utility model describes by specific embodiment, it will be appreciated by those skilled in the art that, under the situation that does not break away from the utility model scope, can also carry out various conversion and be equal to alternative the utility model.Therefore, the utility model is not limited to disclosed specific embodiment, and should comprise the whole execution modes that fall in the utility model claim scope.
