Abstract

The utility model relates to a mobile phone earphone, which comprises a loudspeaker connected with a mobile phone circuit. The loudspeaker is mechanically connected with the interior of a mobile phone through a telescoping mechanism, so that the loudspeaker can extend out of a mobile phone panel or shrink back to the mobile phone panel. The front end tangent plane of an earphone part which extends out of the mobile phone panel is greater than the rear end tangent plane, which presents a capped-nail shape. Therefore, a mobile phone can be hung on the ear during conversation, and both hands are released, which brings great convenience for a user. When the conversation is finished, the earphone can shrink back to the panel without influencing the beautiful appearance.

Description

The mobile phone receiver

The utility model relates to a kind of mobile phone receiver

Need grasp telephone set when the mobile phone that uses is conversed now, need work, during as driving, by situations such as things, use the telephone set conversation just very inconvenient when running into both hands.External earphone is because wiring is longer, and knotting easily needs both hands to work in coordination with and unties during use.When work or driving, when both hands can't be thrown off, use external earphone also very inconvenient.

The purpose of this utility model is to provide a kind of improved mobile phone receiver, mobile phone can be hung on the ear by this receiver, and both hands are freed.

For achieving the above object, mobile phone receiver of the present utility model comprises a loud speaker that is connected with mobile telephone circuit, this loud speaker is connected with the mobile phone internal mechanical by a telescoping mechanism so that loud speaker stretches out the mobile phone panel or is withdrawn on the mobile phone panel, the preceding end grain of part that stretches out the mobile phone panel at receiver is formed with the spike of cap greater than the back end grain.

Above-mentioned telescoping mechanism is made of circuitous shape guide rail, U-shaped hook, spring, circuitous shape guide rail is positioned at away from loud speaker one end, be divided into four sliding ripples that join successively, the join junction of two sliding ripples forms the low ladder of sliding ripple after the advancing slip wave height, one V-arrangement hanging groove is arranged on the guide rail top, described U-shaped is linked up with an end and is arranged in guide rail, the other end is positioned at the trepanning of the protective frame below of loud speaker, described spring is between the protective frame and guide rail of loud speaker, when loud speaker was withdrawn on the mobile phone panel, described U-shaped hook had been hung on the V-arrangement hanging groove under the spring tension effect.

The utility model has been realized a kind of new mobile phone occupation mode, make mobile phone when conversation, can hang on the ear, both hands are freed, under work, life or driving situation, bring great convenience to the user, behind the end of conversation, receiver is retractable on the panel, the same with common mobile phone, do not affect the appearance, do not take up space.

Below in conjunction with accompanying drawing utility model is described further:

Fig. 1 is the utility model mobile phone receiver schematic diagram;

Fig. 2 is the utility model mobile phone receiver A-A cutaway view.

As shown in Figure 1; mobile phone receiver of the present utility model comprises a loud speaker 1 that is connected with mobile phone 17 circuit; the outer fender bracket 2 that is with of loud speaker 1; there is a pipe box 3 below of fender bracket 2; at a end one circuitous shape guide rail 4 is arranged away from loud speaker 1; this guide rail 4 is by sliding ripple 5; sliding ripple 6; sliding ripple 7; sliding ripple 8 joins successively and forms; form the ladder 9 that sliding ripple 5 is higher than sliding ripple 6 in sliding ripple 5 and the joint of sliding ripple 6; form the ladder 10 that sliding ripple 6 is higher than sliding ripple 7 in sliding ripple 6 and the joint of sliding ripple 7; form the ladder 11 that sliding ripple 7 is higher than sliding ripple 8 in sliding ripple 7 and the joint of sliding ripple 8; form the ladder 12 that sliding ripple 8 is higher than sliding ripple 5 in sliding ripple 8 and the joint of sliding ripple 5, a V-arrangement hanging groove 13 is arranged on the top of guide rail 4.U-shaped is linked up with 14 1 ends and is arranged in guide rail 4, and the other end is arranged in the trepanning 15 of the fender bracket 2 parts below of pipe box 3.One spring 16 is arranged in sleeve pipe 3, and these spring 16 two ends withstand on the below of the wall and the fender bracket 2 of guide rail 4 respectively.Above-mentioned U-shaped hook passes the inner chamber of spring 16, and contact with spring 16 so that form an inside pressure and make U-shaped link up with 14 end to be close to guide rail 4.The utility model is realize receiver like this flexible after being installed on mobile phone: when receiver is depressed receiver under elongation state, after the end of U-shaped hook 14 slides into front end along the sliding ripple 5 in the guide rail 4, fall into sliding ripple 6, after hanging up, the receiver front portion is rebounded by the tension force of spring 16, the end of U-shaped hook 14 slides in the sliding ripple 7 and drops on the V-arrangement hanging groove 13, and the loud speaker of receiver is just withdrawn on the mobile phone panel; When depressing receiver once more, the end of V-arrangement hook 14 slides into sliding ripple 8 from sliding ripple 7, and behind the relieving receiver, spring 16 is upheld, and U-shaped is linked up with 14 ends and is slipped in the sliding ripple 5 along sliding ripple 8.The ladder of the joint between the sliding ripple prevents that U-shaped from linking up with that 14 ends are reverse slides.Mobile phone receiver of the present utility model stretch out the mobile phone faceplate part make the band cap spike, the outer end is that the cross section of speaker portion is greater than interior end section, be complementary with the recess of human body ear below, can hang on the ear after receiver is stretched out, like this, just can slip out of the hand during conversation hangs on mobile phone on the ear, and both hands are freed.
