Description

Three-dimensional earphone of pleasant formula

Technical Field

The utility model relates to an in-ear earphone technical field, concretely relates to three-dimensional earphone of in-ear.

Background

At present, the earphone is closely related to the daily life and work of people. According to the wearing form of the earphone, the earphone can be divided into different types such as a suspension type earphone, an in-ear type earphone and a head-wearing type earphone, wherein the in-ear type earphone is small in size, convenient to carry and quite popular with consumers.

In-ear earphones in the market now, the earphone sleeve is usually directly installed on the leading sound pipe of the earphone front shell through interference, although the installation mode of this kind of earphone sleeve can satisfy the wearing demand, the earphone sleeve installation back is not firm, and when the people was in the motion state, the earphone sleeve appeared droing easily, had reduced user's use and had experienced.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing an earmuff installation is firm, avoid the earmuff to appear coming off, improve the three-dimensional earphone of in-ear formula that the user used and experienced.

In order to solve the technical problem, the technical scheme of the utility model is that: an in-ear type stereo earphone comprises an earphone body, a sound guide tube arranged at one end of the earphone body, and an earmuff sleeved on the outer wall of the sound guide tube; the outer surface of the sound guide pipe is inwards recessed to form an annular groove, and the bottom surface of the annular groove is provided with a plurality of positioning bulges; the earmuffs are provided with through holes for the sound guide tubes to pass through, the inner surfaces of the through holes extend inwards to form positioning rings, and the positioning rings are provided with a plurality of positioning grooves correspondingly embedded with the positioning protrusions.

Preferably, more than two positioning bulges are arranged; the number of the positioning grooves is consistent with that of the positioning protrusions.

Preferably, the height of the positioning projection is smaller than the depth of the annular groove.

Preferably, the width of the annular groove is larger than that of the positioning ring; the depth of the annular groove is greater than the height of the positioning ring; the width and the high relation between injecing annular groove and the holding ring can make in the holding ring can imbed the annular groove, and the location arch on the annular groove can imbed in the positioning groove on the holding ring simultaneously, and this can improve the installation fastness between earmuff and the leading note pipe, avoids the earmuff to drop from the leading note pipe.

Preferably, a filter screen is fixedly arranged in the sound guide pipe; can avoid external dust to get into earphone body 1's inside through leading the sound pipe through the design filter screen.

Preferably, the earmuff is a silicone rubber earmuff.

The utility model discloses technical effect mainly embodies: the annular groove of leading the sound pipe is put into through the holding ring to the earmuff, inlays the positioning groove on the holding ring to the location arch in the annular groove again, can be the firm installation on leading the sound pipe of earmuff to can avoid the earmuff to appear droing, improve user's use and experience.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.

An in-ear type stereo earphone is shown in figure 1 and comprises an earphone body 1, a sound guide tube 2 arranged at one end of the earphone body 1, and an earmuff 3 sleeved on the outer wall of the sound guide tube 2.

As shown in fig. 2 to 5, an annular groove 21 is recessed inward on the outer surface of the sound guide tube 2, a plurality of positioning protrusions 22 are disposed on the bottom surface of the annular groove 21, and a filter screen 23 is fixedly mounted inside the sound guide tube 2. By designing the filter screen 23, external dust can be prevented from entering the inside of the earphone body 1 through the sound guide tube 2. The ear muff 3 is provided with a through hole 31 for the sound guide tube 2 to pass through, the inner surface of the through hole 31 extends inwards to be provided with a positioning ring 32, and the positioning ring 32 is provided with a plurality of positioning grooves 33 which are correspondingly embedded with the positioning protrusions 22.

In the present embodiment, two or more positioning protrusions 22 are provided. The number of the positioning grooves 33 is the same as that of the positioning protrusions 22.

In the present embodiment, the height of the positioning projection 22 is smaller than the depth of the annular groove 21.

In this embodiment, the width of the annular groove 21 is greater than the width of the retaining ring 32; the depth of the annular groove 21 is greater than the height of the retaining ring 32. The width and height relationship between the annular groove 21 and the positioning ring 32 are defined, so that the positioning ring 32 can be embedded into the annular groove 21, and the positioning protrusion 22 on the annular groove 21 can be embedded into the positioning groove 33 on the positioning ring 32, which can improve the installation firmness between the ear muff 3 and the sound guide tube 2 and prevent the ear muff 3 from falling off from the sound guide tube 2.

In the present embodiment, the ear cap 3 is a silicone rubber earplug.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
