[0033] Please refer to Figures 1 to 7The present invention proposes a three-layer composite sleeping earphone. The preferred embodiment of the present invention includes an ear hook 1, a power supply part 2 and a sound cavity part 3. The power supply part 2 and the sound cavity part 3 are respectively arranged at two ends of the ear hook 1.

[0034] The main body of the three-layer composite sleeping earphone in this embodiment is wrapped by a soft rubber shell, and a layer of noise reduction and sound insulation cotton 6 of moderate thickness is embedded inside the shell. A preset channel is provided inside the noise reduction and sound insulation cotton 6, and a slender sound guide tube 7 is embedded in the channel. One end of the sound guide tube 7 is connected to the earphone driving unit, and the other end is opened to face the ear canal, forming a direct sound transmission path.

[0035] The sound cavity part 3 includes a connecting part 4, an ear cap 5, noise reduction and sound insulation cotton 6, a sound guide tube 7 and a moving iron sound generator 8. The ear cap 5 is arranged at the front end of the connecting part 4, the noise reduction and sound insulation cotton 6 is arranged in the ear cap 5, and the moving iron sound generator 8 is arranged inside the front end of the connecting part 4. The ear cap 5 is provided with a sound outlet hole, the sound guide tube 7 is embedded in the noise reduction and sound insulation cotton 6, one end of the sound guide tube 7 is connected to the moving iron sound generator 8, and the other end is connected to the sound outlet hole.

[0036] The assembly structure of the sound guide tube 7 and the moving iron sound generator 8 is as follows: Figure 7 As shown, a sound mouthpiece 13 is provided at one end of the moving iron sound generator 8 . During assembly, one end of the sound guide tube 7 is inserted into the sound mouthpiece 13 of the moving iron sound generator 8 .

[0037] In this embodiment, the moving iron sound generator 8 is arranged at the front end of the connecting part 4, rather than in the ear cap 5, so that the user will not feel a hard object when wearing it, thereby effectively improving the wearing comfort. The sound transmission of the moving iron sound generator 8 is guided to the vicinity of or into the ear canal of the user through the sound guide tube 7, which can reduce sound leakage, reduce the loss during sound transmission, and increase the volume of the sound heard by the human ear. The noise reduction and sound insulation cotton 6 can effectively isolate the noise of the external environment and improve the sound quality of the earphone.

[0038] The sound cavity part 3 in this embodiment, that is, the ear cap 5 is composed of an outer soft rubber layer, a middle sponge layer (noise reduction and sound insulation cotton 6) and an internal sound guide tube 7, which can create a soundproof and comfortable sleeping listening experience for the user.

[0039] The middle sponge layer (noise reduction and sound insulation cotton 6) uses an open cell structure with low allergy and high sound absorption. It can absorb and isolate external noise to create a quiet listening environment, and ensure air circulation, reduce the dampness of the ears, and increase the comfort when wearing. In addition, this embodiment can minimize external noise interference through the physical isolation characteristics of the middle sponge layer and the overall fitting design of the earphone, providing users with an immersive sleep-aiding audio experience.

[0040] In other embodiments, the noise reduction and sound insulation cotton 6 can also be made of glass wool, rock wool, rubber wool, rubber-plastic sponge, recycled sponge, silicone sponge, sound insulation sponge, rebound PU foam sponge, air cushion sponge, water-absorbing sponge, high-density sponge, PU shaping sponge, PPC hydrophilic sponge, self-skinning polyurethane foam, foam, resistance sponge, etc.

[0041] The precisely designed sound guide tube 7 is placed in the middle sponge layer (noise reduction and sound insulation cotton 6) and is connected to the outside through a hole, so that the audio signal can be accurately and losslessly transmitted to the ear canal, reducing sound attenuation, ensuring clear sound quality while avoiding sound leakage and not affecting others.

[0042] The sound guide tube 7 is made of high-conductivity material, with one end connected to the micro driver unit of the earphone and the other end opening precisely positioned at the entrance of the ear canal, ensuring that the audio signal reaches the eardrum directly with the shortest path and lowest loss, achieving pure and clear sound quality output.

[0043] Furthermore, in this embodiment, a dustproof net 12 is provided between the noise reduction and sound insulation cotton 6 and the ear cap 5. The dustproof net 12 is honeycomb-shaped, which can effectively prevent dust and other impurities from entering the earphone and improve its service life.

[0044] In this embodiment, the ear cap 5 is made of soft rubber material, specifically highly elastic, skin-friendly medical silicone material, which can ensure biocompatibility and safety for long-term use, ensure that there is no pressure when wearing it for a long time, and there will be no foreign body sensation even if turning over, effectively avoiding discomfort during sleep.

[0045] Silicone has good biocompatibility, is non-irritating, non-toxic, and non-allergic to human tissues, and has very few body rejection reactions. Using silicone to make the ear cap 5 can improve user safety and wearing comfort.

[0046] In other embodiments, the soft rubber material page can be made of TPU, PVC, rubber, TPE, TPR, TPV, etc., with a hardness range of 0 to 100 degrees.

[0047] Furthermore, in this embodiment, the connecting portion 4 is L-shaped, and the bending part of the connecting portion 4 is a transition arc. The arc-shaped connecting portion 4 can ensure that the sound outlet is facing the ear canal of the user when wearing.

[0048] Furthermore, in this embodiment, the ear hook 1 is arc-shaped. When worn, one side of the ear hook 1 fits against the user's ear, and the sound outlet faces the ear canal of the ear.

[0049] In this embodiment, the ear hook 1 is made of soft rubber, and a memory metal 9 that can be bent at will is arranged inside the ear hook 1. The metal is steel, aluminum, copper, iron or titanium.

[0050] In this embodiment, a charging contact 10 is disposed on one side of the battery unit, and a microphone pickup hole 11 is disposed on the other side.

[0051] The beneficial effects of the three-layer composite sleeping earphone of the present invention are:

[0052] 1. The present invention adopts a three-layer material combination design that perfectly fits the contour of the human ear, reduces the pressure on the ear canal, can adapt to various sleeping positions, and ensures worry-free wearing during sleep.

[0053] 2. The present invention adopts a sponge layer to effectively isolate environmental noise, create a quiet sleeping environment for users, and help them fall asleep quickly.

[0054] 3. The present invention adopts a sound guide tube design to ensure that the audio signal is directly and efficiently transmitted to the ear canal, the sound quality is clear and undistorted, and it can also effectively prevent sound leakage, ensuring the original presentation of sleep-aiding audio such as music and white noise.

[0055] 4. The present invention can better assist users to enter a deep sleep state, promote healthy sleep, be beneficial to physical and mental health, quickly enter a deep sleep state, and play a positive role in improving sleep quality.

[0056] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
