The emitter is connected with the signal source, and a front stage or an earphone amplifier can be connected in front of the emitter to improve the tone quality and adjust the tone color. In order to enhance the sound quality and sound effect of the earphone, the headset with the multiple speakers has the problem of easy sound leakage due to the fact that the number of the speakers is more than two, and the headset needs to be sound-proof and anti-slip to the outside of the headset.
Disclosure of Invention
The technical problem to be solved by the utility model is as follows: the provided headset avoids the problem of sound leakage and can meet the using effect of people in all ages.
In order to solve the technical problems, the utility model is realized by the following technical scheme: the utility model provides a headset of making an uproar falls in many speakers head, includes earphone bracket, earphone main part, protection casing, sleeve pipe, screw rod and snap ring, protection casing fixed mounting is at earphone bracket bottom both ends, sleeve pipe fixed mounting is on the protection casing, the fixed cover of snap ring connects and installs in earphone main part, snap ring slidable mounting is on the sleeve pipe, sleeve fixed mounting is on the protection casing, the screw rod outer end is rotated through ball bearing and is installed in the sleeve, the inner and snap ring screw thread transmission of screw rod is connected, the sleeve outer end has the opening, the screw rod outer end extends to sleeve outer end opening part.
Preferably, the inner end of the sleeve is fixedly connected with the inner wall of the protective cover through a support rod.
Preferably, the inner wall of the protective cover is fixedly attached with a sound-absorbing plate.
Preferably, the inside of the protective cover is provided with a hollow structure, and the electric wire of the earphone body is arranged inside the protective cover.
Compared with the prior art, the utility model has the advantages that: the problem of sound leakage can be avoided appearing in the earphone main part outside through setting up the protection casing, to the user of different age groups, interval between two adjustable earphone main parts of this earphone, rotate the intraductal screw rod of cover through instruments such as screwdrivers, drive the snap ring, the relative sleeve pipe of earphone main part removes, and then adjust the interval between two earphone main parts, for the tight mode of traditional arc support clamp, this earphone of making an uproar can not be because of the too big ear ache that leads to of clamping-force, can obtain better use experience effect.
Description of the drawings:
the utility model is further described below with reference to the accompanying drawings.
Fig. 1 is a schematic view of the internal structure of the present invention.
Fig. 2 is an enlarged schematic view of the structure at M in fig. 1.
The specific implementation mode is as follows:
the present invention will be described in detail with reference to specific embodiments below:
as shown in fig. 1 and 2, the multi-speaker headset with noise reduction function comprises a headset support 1, a headset main body 2, a protective cover 3, a sleeve 4, a sleeve 5, a screw rod 6 and a snap ring 9, wherein the protective cover 3 is fixedly arranged at two ends of the bottom of the headset support 1, the sleeve 4 is fixedly arranged on the protective cover 3, the snap ring 9 is fixedly sleeved on the headset main body 2, the snap ring 9 is slidably arranged on the sleeve 4, the sleeve 5 is fixedly arranged on the protective cover 3, the outer end of the screw rod 6 is rotatably arranged in the sleeve 5 through a ball bearing, the inner end of the screw rod 6 is in threaded transmission connection with the snap ring 9, the outer end of the sleeve 5 is provided with an opening, and the outer end of the screw rod 6 extends to the opening of the outer end of the sleeve 5.
In practical use, in order to increase the stability of the installation structure of the sleeve 5, the inner end of the sleeve 5 is fixedly connected with the inner wall of the protective cover 3 through a support rod 7.
Because this earphone is provided with a plurality of speakers, in order to further reduce earphone main body 2 sound leakage problem, fixed attached on the inner wall of protection casing 3 is provided with noise reduction board 31.
The inside hollow structure that sets up of protection casing 3, the electric wire of earphone main part 2 is arranged in inside protection casing 3, promotes the clean and tidy degree of circuit part.
Can avoid the 2 outsides of earphone main part to appear leaking the sound problem through setting up protection casing 3, to the user of different age groups, interval between two adjustable earphone main parts 2 of this earphone, rotate screw rod 6 in the sleeve pipe 5 through instruments such as screwdrivers, drive snap ring 9, the relative sleeve pipe 4 of earphone main part 2 removes, and then adjust the interval between two earphone main parts 2, for the tight mode of traditional arc support clamp, this earphone of making an uproar can not lead to the ear ache because of the clamping-force is too big, can obtain better use experience effect.
It is to be emphasized that: it will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
