[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model incorporates a sound-conducting earpiece body fitted onto the speaker of the temple of the glasses. When the speaker of the temple of the glasses emits sound, the sound enters the sound-conducting channel of the sound-conducting earpiece body. Since the sound outlet of the sound-conducting earpiece body forms a relatively closed cavity with the ear, the interference from external noise is greatly reduced when the sound propagates in this cavity. At the same time, the helix of the ear is located in the helix relief groove, which allows the sound outlet of the sound-conducting earpiece body to fit better with the ear, effectively reducing sound leakage. This makes it difficult for others to hear the sound emitted by the smart glasses from a certain distance, thus improving the user's privacy.

[0017] 2. When installing this utility model, press the left end of the operating rod and rotate it around the pin. Then, put the sliding hole of the sound guide earpiece body onto the temple of the glasses. After installation, release the operating rod. At this time, the restoring force of the spring can drive the limiting block to move downward and lock into the limiting groove on the temple of the glasses. This avoids the loosening of the sliding hole of the elastic material due to reduced friction and material fatigue during strenuous exercise or long-term wear, and better fixes the sound guide earpiece body to the temple of the glasses.

[0027] Example 1

[0028] This specific embodiment is a sound-guiding ear sleeve structure, the structural schematic diagram of which is shown in Figures 1-5. The structure includes a sound-guiding ear sleeve body 1, which is an integrally formed structure. One end of the sound-guiding ear sleeve body 1 is provided with a sliding hole 2, and the other end of the sound-guiding ear sleeve body 1 is provided with a sound outlet hole 3. The inner wall of the sliding hole 2 is provided with a sound guiding channel 4 that communicates with the sound outlet hole 3. The outer surface of the sound-guiding ear sleeve body 1 and located between the sound outlet hole 3 and the sound guiding channel 4 are provided with an ear helix clearance groove 5.

[0029] It also includes the temple of the glasses 6 and the speaker 7 mounted on the temple of the glasses 6. The sliding hole 2 is fitted on the outer surface of the temple of the glasses 6, and the speaker 7 is connected to the sound guide channel 4. The temple of the glasses 6 is equipped with a smart chip and a battery. The sound guide ear cover body 1 is fitted on the temple of the glasses 6, and the sound transmitted by the speaker 7 is guided into the ear through the sound guide ear cover body 1, which effectively reduces sound dispersion and protects privacy.

[0030] In this embodiment, the sound-conducting earpiece body 1 is made of elastic material; thus, the sliding hole 2 of the sound-conducting earpiece body 1 can be directly fitted onto the surface of the eyeglass temple 6, so that the sound outlet 3 fits against the ear and is fixed to the eyeglass temple 6 by the elasticity of the elastic material. Since the sound-conducting earpiece body 1 is detachable, it can be removed when you do not want to use it, which is very convenient.

[0031] As shown in Figure 5: In this embodiment, the ear helix relief groove 5 is opened on one side edge near the temple 6 and the sound outlet 3. When the temple 6 of the glasses is worn, the sound outlet 3 of the sound-conducting ear cover body 1 fits against the user's ear canal. Due to the presence of the ear helix relief groove 5, the ear helix of the ear is located in the ear helix relief groove 5, so that the sound outlet 3 of the sound-conducting ear cover body 1 fits better against the ear.

[0032] Working principle: By fitting a sound-guiding earpiece body 1 onto the speaker 7 of the temple 6, when the speaker 7 of the temple 6 emits sound, the sound is first transmitted through the speaker 7 on the temple 6. At this time, because the sliding hole 2 of the sound-guiding earpiece body 1 wraps around the speaker 7, the sound will enter the sound-guiding channel 4 of the sound-guiding earpiece body 1. Since the sound outlet 3 of the sound-guiding earpiece body 1 forms a relatively closed cavity with the ear, the interference from external noise will be greatly reduced when the sound propagates in this cavity. At the same time, due to the presence of the auricle relief groove 5 on the sound-guiding earpiece body 1, the auricle of the ear is located in the auricle relief groove 5, so that the sound outlet 3 of the sound-guiding earpiece body 1 fits better with the ear, effectively reducing sound leakage. This makes it difficult for others to hear the sound emitted by the smart glasses from a certain distance, thus improving the user's privacy.

[0033] Example 2

[0034] As shown in Figures 6 and 7: This specific embodiment is a sound-conducting earpiece fixing structure. The sound-conducting earpiece body 1 is usually connected to the temple 6 of the glasses through an elastic material. During strenuous exercise or long-term wear, it may loosen due to reduced friction, material fatigue, or other reasons. In this embodiment, an elastic limiting component 8 is provided on the outer surface of the sound-conducting earpiece body 1, and a limiting groove 9 corresponding to the elastic limiting component 8 is provided on the outer surface of the temple 6. In this way, the elastic limiting component 8 can fix the sound-conducting earpiece body 1 in the limiting groove 9 of the temple 6, making it more stable and preventing it from easily falling off during daily use.

[0035] As shown in Figures 6-8: In this embodiment, the elastic limiting component 8 includes a fixed base 801 fixedly connected to the upper surface of the sound guide earpiece body 1. A cavity 802 is formed inside the fixed base 801. An operating rod 804 is rotatably connected between the front and rear inner walls of the cavity 802 via a pin 803. One end of the operating rod 804 is located outside the fixed base 801, and the other end of the operating rod 804 is equipped with a limiting block 805 corresponding to the limiting groove 9. An elongated hole 806 is formed on the upper surface of the fixed base 801. The rod 804 is located inside the elongated hole 806. The limiting block 805 is slidably inserted into the lower right surface of the fixed base 801. The limiting block 805 can slide up and down. The bottom end of the limiting block 805 is an arc structure. The top end of the limiting block 805 is located inside the cavity 802 and is fixedly connected to a spring 807. The other end of the spring 807 is fixedly connected to the inner top wall of the cavity 802. A through hole 808 is provided on the limiting block 805. One end of the operating rod 804 is fixedly connected to a ball 809 and is located inside the through hole 808.

[0036] During installation, press the left end of the operating lever 804 and rotate it around the pin 803. During the rotation, the operating lever 804 drives the limiting block 805 to move upward through the ball 809 and compress the spring 807. Then, the sliding hole 2 of the sound guide earpiece body 1 is fitted onto the temple 6 of the glasses. After installation, release the operating lever 804. At this time, the restoring force of the spring 807 can drive the limiting block 805 to move downward and lock into the limiting groove 9 on the temple 6 of the glasses. This prevents the sliding hole 2 of the elastic material from loosening due to reduced friction or material fatigue during strenuous exercise or long-term wear, and better fixes the sound guide earpiece body 1 to the temple 6 of the glasses.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
