Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to an ear-hook earphone that prevents sound leakage. Background Art

[0002] When the current mainstream ear-hook headphones are worn on the ears, such as the ear-hook Bluetooth headphones with publication number CN217825280 U published on the Chinese patent website, the headphone body usually fits the face close to the tragus, and the sound in the main body is only close to the ear hole. This will result in the sound being unable to be directly transmitted toward the entrance of the external auditory canal after being transmitted from the sound outlet of the headphone body, and the sound output of the headphone body is difficult to focus and too divergent, resulting in serious sound leakage. Therefore, there is a need for an ear-hook headphone that can prevent sound leakage. Utility Model Content

[0003] Based on the technical problems of existing hanging earphones, the utility model provides an anti-sound leakage hanging earphone.

[0004] The utility model provides an anti-sound leakage earphone, comprising an anti-sound leakage earplug, wherein the anti-sound leakage earplug comprises a sound leakage prevention part arranged coaxially with the ear hole, and the inner wall of the sound leakage prevention part is fixedly installed with a coaxially distributed reinforcement part.

[0005] When the sound leakage preventing portion is inserted into the ear hole, the reinforcing portion applies elastic pressure to the sound leakage preventing portion to increase the elastic squeezing force when the sound leakage preventing portion contacts the inner wall of the ear hole.

[0006] Preferably, the sound leakage preventing portion is composed of an elastic shell having an arc-shaped outer surface, and the outer surface of the elastic shell is elastically adapted to the shape of the outer edge of the ear hole.

[0007] Through the above technical solution, the ear canal can be closely attached to the sound outlet, making the sound output of the earphone more focused, the distance of the sound direction closer and more accurately transmitted to the human ear, compressing the space and distance that the sound propagates in the air, and reducing sound leakage.

[0008] Preferably, the reinforcement portion is formed by an elastic ring made of the same material as the elastic shell, and the cross section of the elastic ring is distributed at right angles.

[0009] Through the above technical solution, the outer surface of the sound leakage prevention part can be tightly elastically squeezed to fit the inner wall of the ear hole, which not only prevents sound leakage, but also prevents the sound leakage prevention earplug from slipping.

[0010] The beneficial effects of the present invention are:

[0011] 1. By setting up the anti-sound leakage part, it can fit closely to the ear hole, so that the sound outlet can be closer to the external auditory canal, making the output of the earphone sound more focused, and the distance of the sound direction is closer and more accurately transmitted to the human ear. The space and distance of sound propagation in the air are compressed, which can reduce sound leakage and the loss of the sound energy field. The sound field is larger, the low frequency is stronger, the sound restoration is higher, and the user's listening experience is better.

[0012] 2. By providing a reinforcement part, the outer surface of the sound leakage prevention part can be tightly elastically squeezed to fit the inner wall of the ear hole, which not only prevents sound leakage, but also prevents the sound leakage prevention earplug from slipping.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figures 1-9 A sound leakage-proof earphone includes an earhook 1, one end of the earhook 1 is fixedly installed with a battery compartment 2, the other end of the earhook 1 is clamped with an earphone shell 3 through a buckle 6, the earphone shell 3 includes a first shell 4 and a second shell 5, a fixing column 7 is fixedly installed on the inner surface of the first shell 4, and a fixing sleeve 8 is fixedly installed on the surface of the second shell 5, and the arc surface of the fixing column 7 is movably clamped with the inner side wall of the fixing sleeve 8.

[0025] A fixing compartment 9 for fixing the earphone driving unit is also fixedly installed on the inner surface of the first shell 4, and a charging interface 10 is also fixed on one side surface of the first shell 4; the fixing compartment 9 for fixing the earphone driving unit is provided to fix the earphone driving unit to prevent it from moving due to vibration inside the earphone shell 3, and a charging interface 10 is provided to charge the earphone battery through the charging interface 10.

[0026] A sound outlet hole 11 is fixedly installed on one side of the earphone housing 3, and the sound outlet hole 11 is arranged on one side of the fixing compartment 9 for fixing the earphone driving unit; the sound outlet hole 11 is arranged so that the center line of the sound outlet hole 11 coincides with the center line of the fixing compartment 9 for fixing the earphone driving unit, so that the earphone driving unit converts the electrical signal into sound and releases it through the sound outlet hole 11.

[0027] The ear hook 1 and the earphone housing 3 have a certain inclination angle A, and the angle range of the inclination angle A is 15°-20°; when the ear hook 1 is hung on the auricle, the earphone housing 3 can better fit the external auditory canal due to the inclination angle A.

[0028] The earphone shell 3 has a certain inclination angle B, which makes the earphone shell 3 have an obtuse angle shape, and the angle range of the inclination angle B is 42°-47°; the inclination angle B is set so that the sound outlet 11 can be closer to the external auditory canal, making the output of the earphone sound more focused, and the distance of the sound direction is closer and more accurately transmitted to the human ear, compressing the space and distance of sound propagation in the air, reducing the loss of the sound energy field, the sound field is larger, the low frequency is stronger, the sound restoration is higher, and the user's listening experience is better.

[0029] like Figure 4 、 Figure 7-Figure 9 As shown, the outer surface of the sound outlet hole 11 is movably connected to the sound leakage prevention earplug 12. The specific connection is as follows: the sound outlet hole 11 is movably connected to the connecting groove 123 on the sound leakage prevention earplug 12, so that the sound leakage prevention earplug 12 can be rotated according to the actual wearing posture.

[0030] The sound leakage prevention earplug 12 includes a sound leakage prevention part 121 arranged coaxially with the ear hole. The sound leakage prevention part 121 is composed of an elastic shell with an arc-shaped outer surface. The outer surface of the elastic shell is elastically adapted to the shape of the outer edge of the ear hole. The material of the sound leakage prevention earplug 12 can be set to memory sponge; memory sponge is usually made of polyurethane foam material, which has good elasticity and softness, which enables the sound leakage prevention earplug 12 to better fit the ear canal and effectively reduce noise, especially in the low-frequency range.

[0031] A coaxially distributed reinforcement portion 122 is fixedly mounted on the inner wall of the sound leakage prevention portion 121 . The reinforcement portion 122 is composed of an elastic ring made of the same material as the elastic shell, and the cross section of the elastic ring is distributed at right angles.

[0032] When the sound leakage preventing portion 121 is inserted into the ear hole, the reinforcing portion 122 applies elastic pressure to the sound leakage preventing portion 121 to increase the elastic squeezing force when the sound leakage preventing portion 121 contacts the inner wall of the ear hole.

[0033] Compared with the existing technology, this design is superior to the traditional earplug-style earphones. It is a way of completely plugging into the ear canal to transmit sound. The wearing shape of the arc-shaped elastic shell is to lightly press on the opening of the external auditory canal of the auricle. The advantage is that it does not squeeze the ear canal while ensuring no sound leakage during long-term wear, and it will not hurt after long-term wearing. The sound waves are transmitted from the opening of the external auditory canal to the eardrum of the internal auditory canal, and at the same time it has a certain protective effect on the human ear's hearing.

[0034] Working principle: When the present invention is worn, the ear hook 1 is hung on the ear. Since the ear hook 1 is provided with an inclination angle A, the earphone shell 3 can better fit the tragus. At the same time, the earphone shell 3 is provided with an inclination angle B, so that one end of the earphone shell 3 extends over the tragus to the external auditory canal, so that the sound outlet 11 is facing the external auditory canal and is closer to the external auditory canal, so that the output of the earphone sound is more focused, the distance in the direction of the sound is closer and more accurately transmitted to the human ear, and the space and distance for the sound to propagate in the air are compressed, which can reduce sound leakage of the earphone and reduce the loss of the sound energy field.

[0035] When wearing, the sound leakage prevention part 121 of the sound leakage prevention earplug 12 is inserted into the ear canal, and the sound directly passes through the sound leakage prevention part 121 and enters the ear canal. At this time, the reinforcement part 122 elastically squeezes the outer surface of the sound leakage prevention part 121 tightly to fit the inner wall of the ear canal, which not only prevents sound leakage, but also prevents the sound leakage prevention earplug 12 from slipping.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
