Description

Technical Field

[0001] This utility model relates to the field of eyewear technology, and in particular to an AI smart glasses and method with good sound output. Background Technology

[0002] AI glasses are wearable devices that integrate functions such as AI voice assistant, Bluetooth headset, translation, navigation, sunglasses, travel, translation, and chat services. AI glasses embed an AI system within the glasses, combining image recognition and natural language processing technologies. They capture visual information through a camera and transmit voice prompts via a speaker, describing surrounding people and objects to the user. In existing technologies, the structure of AI glasses can be found in Chinese patent documents CN214676284U, CN216748327U, CN215526233U, CN211857113U, CN214669871U, etc. Because the temples of AI glasses need to be worn over the ear, at a certain distance from the ear canal, and the temples are typically long and flat, when the speaker is installed inside the temples, the speaker's sound output direction is difficult to directly face the ear, resulting in relatively poor sound quality.

[0003] See Chinese patent document CN211857113U, which discloses a pair of glasses with headphone function. The glasses have a cavity inside the temples that houses the speaker and PCBA. The part of the cavity near the ear is isolated into a separate sound cavity. The temples are provided with sound cavity holes for sound output, so that the sound output part of the glasses is closer to the ear. This design allows the sound to be transmitted to the ear better and improves the acoustic performance of the glasses with headphone function. However, this patent also has the following technical problems: First, since the sound outlet cavity is isolated by the accommodating cavity of the temple, multiple components such as PCBA and cover plate need to be installed inside the temple. In particular, gaps are easily formed at the connection between the cover plate and the sound outlet cavity, making it difficult for the sound outlet cavity to form a complete sealed chamber, which adversely affects the sound effect transmitted by the speaker through the sound outlet cavity. Second, the cavity of the sound outlet cavity, apart from the speaker, is composed of two components: the temple and the cover plate. The overall integrity is poor, which affects the sound output effect. Third, during the speaker's sound output process, especially when emitting low-frequency sounds, airflow disturbances on both sides of the speaker are easily encountered inside the sound outlet cavity, affecting the sound output effect. Utility Model Content

[0004] The technical problem this invention aims to solve is to address the shortcomings of the prior art by providing an AI smart glasses with excellent sound output. This AI smart glasses features a speaker cavity housing inside the temples, where a speaker assembly is installed. The speaker cavity housing is then installed within a second receiving cavity in the temples. This results in a speaker cavity structure, excluding the speaker assembly, consisting of a single speaker cavity housing, providing good integrity, minimizing gaps, and enhancing sound output. Furthermore, the inner wall of the speaker cavity housing can be designed with a curved shape matching the speaker, further improving sound quality. The AI ​​smart glasses also include an outer cavity outside the speaker, with tuning holes on the temple shell connecting to the outer cavity.

[0025] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-8 As shown, this utility model is an AI smart glasses with good sound output, including temples 100 and a frame 200. The temples 100 include a temple body 101, and a temple tail 102 for hanging above the ear is connected to the rear end of the temple body 101. The temples 100 include a temple shell 103, and a temple inner cover 104 is connected to the inner side of the temple shell 103. The front end of the temple shell 103 is pivotally connected to the frame 200. The temple shell 103 has a first receiving cavity 1 and a second receiving cavity 2 at a position corresponding to the temple body 101. The second receiving cavity 2 is located at the rear end of the first receiving cavity 1. A speaker housing 3 is installed inside the speaker housing 3, and a speaker assembly 4 is installed inside the speaker housing 3. The speaker assembly 4 and the inner wall of the speaker housing 3 form a sound cavity 5, and the sound output direction of the speaker assembly 4 faces the sound cavity 5. The temple housing 103 and the speaker housing 3 are respectively provided with sound outlet holes 6 for communicating with the sound cavity 5, and the sound output direction of the sound outlet holes 6 faces the lower part of the temple end 102. The speaker assembly 4 and the inner wall of the second receiving cavity 2 form an outer cavity 7. The temple housing 103 is provided with a tuning hole 8 for communicating with the outer cavity 7, and the speaker assembly 4 is provided with a pressure relief hole 9 for communicating with the sound cavity 5 and the outer cavity 7. Preferably, a sound outlet mesh plate 24 is attached to the outside of the sound outlet hole 6 of the temple housing 103, and a sound outlet mesh cloth 25 is attached between the sound outlet hole 6 of the temple housing 103 and the sound outlet hole 6 of the speaker cavity housing 3; a tuning mesh plate 26 is attached to the outside of the tuning hole 8 of the temple housing 103, and a tuning mesh cloth 27 is attached to the inside of the tuning hole 8 of the temple housing 103.

[0027] The speaker cavity 5 structure of this utility model, apart from the speaker assembly 4, is composed of a single speaker cavity shell 3, which has good integrity, is not prone to connection gaps, and has good sound output effect. The inner wall of the speaker cavity shell 3 can also be designed into a curved surface shape that matches the speaker assembly 4 to further improve the sound output effect. In this embodiment, the speaker 42 is elliptical in shape, and the inner wall of the speaker cavity shell 3 is an elliptical curved surface, and the two shapes correspond and match. In this invention, the temple shell 103 and the speaker cavity shell 3 are respectively provided with sound outlet holes 6 for connecting the sound cavity 5. The sound outlet holes 6 are oriented towards the lower part of the temple tail 102. Therefore, when the temple 100 of the AI ​​smart glasses is worn on the ear, the sound outlet holes 6 are oriented towards the ear canal, allowing for optimal listening to the sound emitted by the speaker.

The temple shell 103 is provided with a tuning hole 8 for connecting the outer cavity 7, and the speaker assembly 4 is provided with a pressure relief hole 9 for connecting the sound cavity 5 and the outer cavity 7. Therefore, when the speaker plays sound, especially low-frequency sound, a pressure difference is formed between the sound cavity 5 and the outer cavity 7. Through the action of the pressure relief hole 9 and the tuning hole 8, pressure can be released and the sound can be adjusted in time, thereby effectively solving the problem of airflow disturbance on the inner and outer sides of the speaker and further improving the sound output effect.

The side wall of the second receiving cavity 2 is provided with several snap-fit ​​mechanisms 210. The extension plate 32 snaps into the snap-fit ​​mechanisms 210 and seals the opening of the second receiving cavity 2. The extension plate 32 on the speaker housing 3 allows for a tight fit with the second receiving cavity 2 and also seals the second receiving cavity 2, resulting in good sealing of the outer cavity 7 formed between the speaker assembly 4 and the inner wall of the second receiving cavity 2, thereby improving the tuning effect of the tuning port 8.

[0030] like Figure 1-4 and Figure 9As shown, there are two temples 100, namely a left temple 100 and a right temple 100 (note: both the left and right temples are labeled 100).

There are two speaker assemblies 4, namely a left speaker assembly 4 and a right speaker assembly 4 (note: both the left and right speaker assemblies are labeled 4). The two speaker assemblies 4 can realize stereo sound output of the left and right channels. The first receiving cavity 1 of the left temple 100 is equipped with a main control PCBA circuit board 10, and the first receiving cavity 1 of the right temple 100 is equipped with a...
