Description

Earplug and earphone device

Technical Field

The present disclosure relates to speaker devices and accessories thereof, and particularly to an earphone device and an earplug thereof.

Background

Many in-ear headphones are equipped with corresponding earplugs that are sleeved around the headphones to allow the user to wear the headphones more securely, however, in order to reduce the foreign body sensation generated when the user wears the headphones and earplugs, the earplugs are often made of soft materials or made of thinner earplugs, both of which reduce the air tightness and support when the headphones and earplugs are worn.

SUMMERY OF THE UTILITY MODEL

According to an embodiment of the present disclosure, an earphone device includes an earphone and an earplug. The earplug comprises an inner tube part and an outer edge part. The inner tube part is provided with a first end and a second end which are opposite to each other, and the first end is suitable for being connected with the earphone. The inner pipe part comprises an elastic zigzag structure. The outer edge portion is provided with a first side and a second side which are opposite to each other, the first side is connected to the second end of the inner tube portion, and the second side extends towards the first end, so that the outer edge portion surrounds the inner tube portion.

According to an embodiment of the present invention, the inner tubular portion has at least one necked-down portion.

According to an embodiment of the present invention, the elastically bending structure includes a first section and a second section, the first section and the second section are sequentially connected along an axial direction of the inner tube portion, and an outer diameter of the first section is smaller than an outer diameter of the second section.

According to an embodiment of the utility model, the wall thickness of the inner tube part in the first section is the same as the wall thickness of the inner tube part in the second section.

According to an embodiment of the utility model, the elastically yielding structure comprises a third section, the first section being connected between the second section and the third section in the axial direction of the inner tube portion, the first section having an outer diameter smaller than the outer diameter of the third section.

According to an embodiment of the utility model, the wall thickness of the inner tube part in the first section, the wall thickness of the inner tube part in the second section and the wall thickness of the inner tube part in the third section are the same.

According to an embodiment of the present invention, an extension length of the outer edge portion in an axial direction of the inner tube portion is larger than a length of the inner tube portion.

According to an embodiment of the utility model, the inner tube part comprises a socket section and is adapted to be connected to the earphone by the socket section, the resilient meander structure being connected between the socket section and the outer rim part.

According to an embodiment of the utility model, the method comprises the following steps: an earphone; and an earplug, comprising: an inner tube portion having opposing first and second ends, wherein the first end is adapted to be connected to the earphone, the inner tube portion comprising a flexible flexure structure; and an outer rim portion having a first side and a second side opposite to each other, the first side being connected to the second end of the inner tube portion, the second side extending in a direction toward the first end, so that the outer rim portion surrounds the inner tube portion.

In view of the above, in the earplug in the present disclosure, the inner tube portion includes the elastic bending structure, so as to have a better elastic deformation capability. Therefore, when a user inserts the earphone and the earplug connected with the earphone into the auditory canal, the elastic bending structure can adapt to various extending angles of the auditory canal and cling to the inner wall of the auditory canal by the elastic deformation of stretching, collapsing and/or turning and the like. And because the elastic bending structure in the auditory canal can generate the collapse amount due to the force application of the hand of the user, when the hand of the user releases the earphone and releases the earplug, the collapse amount is converted into the elastic restoring force to generate the outward proper displacement amount of the earplug in the auditory canal, so that the earplug is naturally adjusted to the most comfortable state without foreign body feeling, and meanwhile, the air tightness and the support performance are maintained.

Detailed Description

Reference will now be made in detail to the exemplary embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1 is a schematic diagram of an earphone device according to an embodiment of the present disclosure. Fig. 2 is a perspective view of the earplug of fig. 1. Fig. 3 is a cross-sectional view of the earplug of fig. 2, which corresponds to line I-I of fig. 2. Referring to fig. 1 to 3, the earphone device 100 of the present embodiment includes an earphone 110 and an earplug 120. Earplug 120 includes an inner tube portion 122 and an outer rim portion 124.

The inner tube 122 has a first end 122a and a second end 122b opposite to each other, the first end 122a is adapted to be connected to the earphone 110, the outer rim 124 has a first side 124a and a second side 124b opposite to each other, the first side 124a is connected to the second end 122b of the inner tube 122, and the second side 124b extends toward the first end 122a, so that the outer rim 124 surrounds the inner tube 122 b.

In one embodiment, the inner tube portion 122 and the outer edge portion 124 are integrally connected, for example, by a material such as silicone or other elastic material. The inner tubular portion 122 includes an elastically deflectable structure 1221 to provide improved elastic deformability.

Fig. 4A-4D illustrate variations of the earplug of fig. 1. With the good elastic deformability provided by the elastically flexible structure 1221 of the inner tubular portion 122, the inner tubular portion 122 can be subjected to tensile deformation as shown in fig. 4A, compressive deformation as shown in fig. 4B, turn-down deformation as shown in fig. 4C, turn-up deformation as shown in fig. 4D, or turn-up deformation in other directions.

Fig. 5A to 5C are wearing flowcharts of the earphone device of fig. 1. When a user inserts the earphone 110 and the earplug 120 connected to the earphone 110 into the ear canal 50 as shown in fig. 5A-5B, the elastic bending structure 1221 (labeled in fig. 2 and 3) of the inner tube portion 122 can adapt to the extending angle of the ear canal 50 and abut against the inner wall of the ear canal 50 by means of elastic deformation such as stretching, collapsing and/or turning.

Since the elastic bending structure 1221 in the ear canal 50 generates a collapsing amount as shown in fig. 5B due to the force applied by the user's hand, when the user's hand releases the earphone 110 and releases the earplug 120, the collapsing amount is converted into an elastic restoring force, so that the earplug 120 generates an outward proper displacement in the ear canal 50 as shown in fig. 5C, and is naturally adjusted to a most comfortable state without a foreign body sensation.

Referring to fig. 3, in an embodiment, the elastically bending structure 1221 includes a first section 1221a, a second section 1221b, and a third section 1221 c. The third section 1221c, the first section 1221a, and the second section 1221b are sequentially connected in the axial direction a of the inner pipe portion 122. That is, the first section 1221a is connected between the second section 1221b and the third section 1221c in the axial direction a of the inner tube portion 122.

In one embodiment, the outer diameter d1 of the first section 1221a is smaller than the outer diameter d2 of the second section 1221b and smaller than the outer diameter d3 of the third section 1221c, such that the inner tubular portion 122 has a constriction N, thereby forming the elastically tortuous structure 1221. In other embodiments, the number of the necking portions N may be plural, and the elastically bending structure 1221 may have other suitable shapes, which is not limited herein.

As shown in fig. 3, in one embodiment, the wall thickness of the inner tube portion 122 in the first section 1221a, the wall thickness of the inner tube portion 122 in the second section 1221b, and the wall thickness of the inner tube portion 122 in the third section 1221c are the same. That is, the elastically deflectable structure 1221 has a uniform wall thickness, which provides good wear support with sufficient structural strength.

In one embodiment, the inner tube portion 122 includes a socket section 1222 at the first end 122a thereof, the socket section 1222 is connected to the earphone 110, and the flexible flexure structure 1221 is connected between the socket section 1222 and the outer rim portion 124. Furthermore, the method is simple. The outer edge 124 extends a length L1 greater than the length L2 of the inner tube 122 in the axial direction a of the inner tube 122, for example, so that the outer edge 124 has a sufficient area to contact the inner wall of the ear canal 50.

In summary, in the earplug of the present disclosure, the inner tube portion includes the elastic bending structure, so as to have a better elastic deformation capability. Therefore, when a user inserts the earphone and the earplug connected with the earphone into the auditory canal, the elastic bending structure can adapt to various extending angles of the auditory canal and cling to the inner wall of the auditory canal by the elastic deformation of stretching, collapsing and/or turning and the like. And because the elastic bending structure in the auditory canal can generate the collapse amount due to the force application of the hand of the user, when the hand of the user releases the earphone and releases the earplug, the collapse amount is converted into the elastic restoring force to generate the outward proper displacement amount of the earplug in the auditory canal, so that the earplug is naturally adjusted to the most comfortable state without foreign body feeling, and meanwhile, the air tightness and the support performance are maintained.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present disclosure, but not to limit the same; although the present disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
