[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 the two ends of the ear hook 1.

[0034] The main body of the three-layer composite sleeping earphones in this embodiment is wrapped by a soft rubber shell, and a layer of noise-reducing and sound-isolating cotton 6 of moderate thickness is embedded inside the shell. A preset channel is provided inside the noise-reducing and sound-isolating 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 portion 3 includes a connecting portion 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 portion 4, the noise reduction and sound insulation cotton 6 is arranged inside the ear cap 5, and the moving iron sound generator 8 is arranged inside the front end of the connecting portion 4. The ear cap 5 is provided with a sound outlet hole, and 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 sounder 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 balanced armature sound generator 8 is positioned at the front end of the connecting portion 4 rather than within the ear cap 5. This eliminates the feeling of a hard object when worn, effectively improving wearing comfort. The sound guide tube 7 directs the sound from the balanced armature sound generator 8 to or within the ear canal, minimizing sound leakage and transmission losses, thereby increasing the volume heard by the human ear. The noise-reducing and sound-insulating cotton 6 effectively isolates the earphones from ambient noise, enhancing their sound quality.

[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-reducing and sound-isolating cotton 6) uses a hypoallergenic, highly sound-absorbing open-cell sponge. This not only absorbs and isolates external noise, creating a tranquil listening environment, but also ensures air circulation, reduces ear dampness, and increases wearing comfort. Furthermore, the physical isolation properties of the middle sponge layer and the overall fit of the earphones minimize external noise interference, 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, and avoiding sound leakage so as not to affect others.

[0042] The sound guide tube 7 is made of high-conductivity material. One end is connected to the micro driver unit of the earphone, and the other end is 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 you turn over, effectively avoiding discomfort during sleep.

[0045] Silicone has good biocompatibility, is non-irritating, non-toxic, and has no allergic reaction to human tissue, and rarely causes body rejection reaction. 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 bend of the connecting portion 4 is a transition arc. The arc-shaped connecting portion 4 can ensure that the sound outlet is facing the user's ear canal when worn.

[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.

[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 provided inside the ear hook 1. The metal is steel, aluminum, copper, iron or titanium.

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

[0051] The beneficial effects of the three-layer composite sleeping earphones of the utility model are:

[0052] 1. This new model adopts a combination design of three layers of materials to perfectly fit the contour of the human ear, reducing the pressure on the ear canal, and can adapt to various sleeping positions, ensuring worry-free wearing during sleep.

[0053] 2. The sponge layer used in this utility model can effectively isolate environmental noise, create a quiet sleeping environment for users, and help them fall asleep quickly.

[0054] 3. This utility model adopts a sound guide tube design to ensure that the audio signal is transmitted directly and efficiently to the ear canal, with clear sound quality and no distortion. It can also effectively prevent sound leakage, ensuring the original presentation of music, white noise and other sleep-aiding audio.
