earbuds

The present invention relates to an earphone, and more particularly to an in-ear earphone.

Referring to Figure 5, a conventional in-ear earphone includes a bezel 10', a front cavity 20', a horn module 30', a rear cavity 40', and a handle 50'. The inner wall of the earmuff 10' protrudes inwardly to form a first abutting portion 11' having a hollow structure. The first abutting portion 11' is mated with the front cavity 20'; the front cavity 20' has a hollow structural connection end. 21', the front end of the connecting end 21' has a second abutting portion 211' protruding outwardly from the radial direction thereof, and the rear end thereof is outwardly expanded to form a receiving end 22'. The receiving end 22' has a hollow structure inside. The receiving cavity 221', the receiving cavity 221' penetrates the hollow structure of the connecting end 21'. When the front cavity 20' is coupled with the earmuff 10', the front cavity 20' extends into the interior of the earmuff 10', and the first abutting portion 11' and the second abutting portion 211' are in contact with each other, so that the two are mutually stuck. Connected. The horn module 30 ′ is disposed in the receiving cavity 221 ′ of the front cavity 20 ′, the rear cavity 40 ′ is engaged with the receiving cavity 221 ′, and the rear cavity 40 ′ is opened through the rear cavity 40 ′. The mounting hole 41' is mounted in the mounting hole 41'.

However, since the conventional in-ear type earphone mechanism has many components, the production cost is large and the assembly yield is low.

The purpose of the present invention is to provide an in-ear earphone that is light in weight, low in cost, high in assembly yield, and good in sound quality, in view of the deficiencies of the above-mentioned prior art.

In order to achieve the above object, the present invention provides an in-ear earphone, comprising an ear cover, a speaker module and a back cover, the ear cover has a semi-spherical and hollow structure, and a sound hole is arranged at the top of the sleeve. The sleeve extends radially from the periphery of the sound hole toward the inside of the sleeve to form a hollow structure. The free end of the abutting portion expands outward and then continues to extend in the radial direction to form a sleeve. The inside of the sleeve has a hollow structure to form a receiving space, and one end of the receiving space penetrates with the hollow structure of the abutting portion, and the other end forms an opening. The horn module is housed in a receiving space of the sleeve. The back cover covers the sleeve end of the earmuff.

As described above, the in-ear earphone of the present invention is composed of an earmuff, a speaker module and a back cover, and a hollow sleeve is disposed at a lower end of the earmuff, and the speaker module can be directly installed in the sleeve, so that the earphone member is reduced. The speaker module is closer to the ferrule, which in turn makes the inventive in-ear headphones lighter in weight, lower in cost, improved in assembly yield, and improved in sound quality.

To elaborate the technical content of the creation, the structural features, the achieved goals and effects, The following is an example and is explained in detail with the drawings.

Referring to the first, second and third figures, the in-ear earphone 100 comprises an ear cover 10, a speaker module 20 and a back cover 30.

The ear cover 10 has a semi-spherical and hollow structure, and a sound hole 111 is defined in the top of the sleeve 11 . The sleeve 11 extends radially from the periphery of the sound hole 111 to the inside of the sleeve 11 to form a hollow structure. Resist the part 12. The free end of the abutting portion 12 is expanded outwardly and further extends in the radial direction to form a sleeve 13 . The sleeve 13 has a hollow structure to form a receiving space 131 , and one end of the receiving space 131 penetrates with the hollow structure of the abutting portion 12 . The other end forms an opening 132.

Referring to the second, third and fourth figures, the upper end surface of the horn module 20 is provided with a sounding body 21 of a hollow circular cylindrical structure, and the horn module 20 is accommodated in the housing of the sleeve 13. In the space 131, the upper end surface of the horn module 20 abuts against the abutting portion 12 in the ear cover 10, and the sounding body 21 protrudes into the hollow structure of the abutting portion 12.

The speaker module 20 has a body 22 and a horn unit 23 mounted in the body 22. The upper end surface of the body 22 is provided with the sounding body 21, and the lower end surface of the body 22 is recessed upward to form a circular concave shape. Slot 24.

The rear cover 30 has a base 31 having a circular plate shape. The lower end surface of the base 31 defines an outlet hole 311. The upper end surface is convexly provided with a hollow annular cylindrical locking portion 32. The rear cover 30 is closed on the sleeve 13 end of the ear cover 10 , and the latching portion 32 is fastened to the lower end of the accommodating space 131 .

The upper end of the holding portion 32 is provided with a tapered portion 321 , and the tapered portion 321 is tapered. When the holding portion 32 is fastened to the lower end of the accommodating space 131, the tapered portion 321 abuts against the lower end surface of the horn module 20.

Please refer to the third and fourth figures. When the in-ear earphone 100 is assembled, the speaker module 20 is installed in the receiving space 131 of the sleeve 13 , and the upper end surface thereof abuts against the ear cover 10 . The sounding body 21 protrudes from the hollow structure of the abutting portion 12, so that the speaker module 20 is closer to the ferrule 11, thereby improving the sound quality of the earphone. The back cover 30 is closed on the sleeve 13 end of the ear cover 10, and the latching portion 32 is fastened to the lower end of the accommodating space 131, and the tapered portion 321 is abutted against the lower end surface of the horn module 20, and the horn module is 20 fixed effects.

In this embodiment, the ear cover 10 is made of a rubber material. Therefore, when the speaker module 20 is installed in the sleeve 13 and the rear cover 30 is covered by the sleeve 13 end of the ear cover 10, the speaker module 20 The holding portion 32 of the back cover 30 can be stably fixed in the sleeve 13 in a stable manner.

As described above, the in-ear earphone 100 is composed of the ear cover 10, the speaker module 20 and the rear cover 30, and a hollow sleeve 11 is disposed at the lower end of the ear cover 10. The speaker module 20 can be directly mounted on the sleeve 13. Therefore, the earphone member is reduced, and the speaker module 20 is closer to the ferrule 11, thereby making the inventive in-ear earphone 100 light in weight, low in cost, improved in assembly yield, and improved in sound quality.
