Description

Technical Field

[0001] This application relates to the field of smart glasses technology, and in particular to a sound cavity cover, temples, and smart glasses. Background Technology

[0002] With the development of technology, smart glasses are becoming increasingly feature-rich. Smart glasses can be equipped with electronic units such as speakers, batteries, and processing devices to transmit information such as audio and virtual images to users and interact with them.

[0003] There are two ways to transmit audio information. One is bone conduction, which is suitable for scenarios where environmental awareness is needed, such as during exercise or driving, but may have issues with weak low-frequency sound quality and ear bone discomfort. The other method uses a speaker. In this method, the speaker is installed on the temple near the ear, and the outer shell of the temple has a sound hole to allow the sound emitted by the speaker to travel to the ear. However, because smart glasses need to be easy to wear, the outer shell of the temple is made of plastic, which results in poor sound quality due to the material properties. Also, because the outer shell of the temple is relatively thin, the sound hole can only be a simple perforation, resulting in poor dust and water resistance.

[0004] Therefore, in order to solve the problems in the prior art, this utility model provides a sound cavity cover, temple, and smart glasses. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a sound cavity cover, temple, and smart glasses to solve the problems in the prior art where the sound cavity cover on smart glasses is mostly made of plastic, resulting in poor sound quality and poor dust and water resistance of the sound hole.

The sound receiving part is connected to the side of the cover plate facing the speaker. The sound transmitting part is provided with an inlet. The sound releasing part is connected to the non-closing surface of the cover plate. A sound path block is inserted into the sound transmitting part from the inlet and the inlet is closed, so that a sound transmission channel is formed between the sound path block and the sound transmitting part. The sound path block is provided with a sound guiding surface, which is used to make the sound propagate in a non-linear manner in the sound transmission channel.

[0008] Furthermore, in a preferred embodiment, the cover plate is provided with a positioning hole on the side facing the speaker, and at least two positioning holes are provided, one of which is for inserting an external positioning stud.

[0009] Furthermore, in a preferred embodiment, the cover plate is provided with a receiving groove on the side facing the speaker, the receiving groove is for housing the speaker, and the bottom of the receiving groove is connected to the sound receiving part.

[0010] Furthermore, in a preferred embodiment, the receiving part and the transmitting part are groove structures with the slot located on the side of the cover plate facing the speaker, the side wall of the transmitting part is connected to the side wall of the receiving part, and the slot of the transmitting part serves as the inlet; the sound path block and the bottom of the slot of the transmitting part are spaced to form the sound transmission channel.

[0011] Furthermore, in a preferred embodiment, one of each of the sound transmission part and the sound path block is provided; the sound playback part is located on the adjacent closed side of the cover plate, the sound playback part has a hole structure, and two sound playback parts are provided, one of which is located on the lower rear side of the cover plate, and the other of which is located on the lower rear side of the cover plate.

[0013] Furthermore, in a preferred embodiment, a pad is provided at the bottom of the sound transmission section, and the pad abuts against the surface of the sound path block near the bottom of the sound transmission section, so that a gap is formed between the sound path block and the bottom of the sound transmission section.

[0014] Furthermore, in a preferred embodiment, two pads are provided, and the two pads are respectively located at the bottom edges of the two slots in the sound transmission section that communicate with the sound receiving section.

[0016] This utility model embodiment also provides a smart glasses, including the aforementioned acoustic cavity cover.

[0017] Compared with the prior art, the acoustic cavity cover, temple, and smart glasses provided by this utility model embodiment have the following advantages: By using a cover plate and acoustic block made of metal, and with a sound receiving part, a sound transmitting part, and a sound releasing part provided on the cover plate, it can be ensured that the sound emitted by the speaker can be concentrated and output in the sound releasing part, and the output sound quality is good and the sound is stereo.

[0024] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0026] This utility model embodiment provides a sound cavity cover.

[0027] ReferenceFigures 1-2 The sound cavity cover is made of metal and is installed on the outer shell of the temple 3. Since the sound cavity cover is also part of the outer shell of the temple 3, for ease of description, in this embodiment, the outer shell of the temple 3 mentioned does not include the part with the sound cavity cover.

[0028] Reference Figures 3-5 Specifically, the acoustic cavity cover includes a cover plate 1 and an acoustic path block 2. The cover plate 1 is connected to the outer shell of the temple 3. The cover plate 1 is used to cover the speaker 4 so that the speaker 4 will not be exposed to the outside and cause damage. At the same time, the cover plate 1 is provided with a sound receiving part 11, a sound transmitting part 12 and a sound playing part 13 connected in sequence. The sound receiving part 11 is connected to the side of the cover plate 1 facing the speaker 4, the sound transmitting part 12 is provided with an inlet, and the sound playing part 13 is connected to the non-covered surface of the cover plate 1.

[0029] The sound receiving section 11 refers to the sound receiving section on the cover plate 1. After the cover plate 1 covers the speaker 4, the inner wall of the cover plate 1 will not directly adhere to the speaker 4. There will be a certain sealed space between the cover plate 1 and the speaker 4. This sealed space is used to store the sound emitted by the speaker 4. This is the sound receiving section 11 on the cover plate 1. In order to transmit these sounds, the sound receiving section 11 on the cover plate 1 should be connected to the outside of the cover plate 1. The hole that connects to the outside of the sound receiving section 11 is the sound transmitting section 13. The purpose is to transmit the sound stored in the sound receiving section 11 so that the user can hear it. The place through which the sound of the sound receiving section 11 passes is the sound transmitting section 12.

[0030] Reference Figures 3-4 The sound path block 2 is inserted into the sound transmission part 12 from the inlet and the inlet is closed, so that a sound transmission channel is formed between the sound path block 2 and the sound transmission part 12. This sound transmission channel will also connect the receiver part 11 and the output part 13. In addition, the sound path block 2 is provided with a sound guide surface 21, which is used to make the sound propagate in the sound transmission channel in a non-linear manner.

[0031] The purpose of setting up the acoustic path block 2 is that, due to the complexity of the sound transmission channel structure, the thin-walled metal cavity cover cannot be made into the aforementioned sound transmission channel by integral molding. Therefore, the cover plate 1 and the acoustic path block 2 are each formed into part of the inner wall of the sound transmission channel through simple processing and molding, and then assembled to form a complex sound transmission channel.

[0032] In summary, given that the acoustic chamber cover is made of metal, the material's inherent properties can be leveraged to improve sound quality. Furthermore, while maintaining a relatively thin acoustic chamber cover and keeping the smart glasses lightweight, it's still possible to more easily and precisely fabricate a complex sound transmission channel. This channel not only improves sound quality but also provides dust and water resistance. Additionally, the metal acoustic chamber cover also protects the speaker 4.

[0033] Reference Figure 2 andFigure 5 As mentioned above, the cover plate 1 is connected to the outer shell of the temple 3. During assembly, in order to facilitate the installation of the cover plate 1, the core purpose of this "facilitation" is to allow the sound receiver 11 on the cover plate 1 to be aligned with the position of the speaker 4 more quickly. Based on this, the cover plate 1 has a positioning hole 14 on the side facing the speaker 4. At least two positioning holes 14 are provided. One positioning hole 14 is for the insertion of an external positioning stud 5. This positioning stud 5 is threaded onto the outer shell of the temple 3. Considering the simplicity of the structure of the cover plate 1, only two positioning holes 14 are provided. The two positioning holes 14 are symmetrically arranged with respect to the center line of the cover plate 1, that is, the two positioning holes 14 are symmetrically arranged with respect to the speaker 4.

[0034] In addition, during actual installation, the positioning hole 14 will be filled with glue to achieve the connection between the cover plate 1 and the outer shell of the temple 3.

[0035] Reference Figure 2 and Figure 5 As mentioned above, the cover plate 1 will cover the speaker 4. In order to receive the sound emitted by the speaker 4 more fully, the cover plate 1 has a receiving groove 15 on the side facing the speaker 4. The speaker 4 will be placed in the receiving groove 15, which serves to limit the speaker 4. The bottom of the receiving groove 15 is connected to the sound receiving part 11. In this way, after the sound emitted by the speaker 4 enters the receiving groove 15, the sound is less likely to move away from the sound receiving part 11. Therefore, the emitted sound can be more fully transmitted to the sound receiving part 11, thereby reducing sound loss.

[0036] Reference Figure 5 Given that the cover plate 1 has a receiving groove 15, and considering the molding method of the sound receiving part 11 and the sound transmitting part 12, the following configuration is provided for simpler molding: the structure of the sound receiving part 11 and the sound transmitting part 12 is a groove structure. The groove openings of the sound receiving part 11 and the sound transmitting part 12 are located on the side of the cover plate 1 facing the speaker 4. The side wall of the sound transmitting part 12 is connected to the side wall of the sound receiving part 11, so that the sound received by the sound receiving part 11 can smoothly enter the sound transmitting part 12. The groove opening of the sound transmitting part 12 serves as an inlet for easy insertion of the sound path block 2. Moreover, there is a gap between the sound path block 2 and the bottom of the groove of the sound transmitting part 12, and this gap forms a sound transmission channel.

[0037] In summary, the sound receiving part 11 and the sound transmitting part 12 are both simply formed by groove structures, and the sound transmission channel can be formed simply by the distance between the sound path block 2 and the sound transmitting part 12. In this way, the production of the cover plate 1 is relatively simple, and the assembly between the cover plate 1 and the sound path block 2 is also very simple.

[0038] Reference Figure 5The sound output section 13 is the final outlet of the sound, so the position of the sound output section 13 on the cover plate 1 will affect the direction of sound emission. Considering that the sound is mainly transmitted to the ear, the sound output section 13 will be located on the side adjacent to the cover plate 1, and it is also provided on the lower and rear sides of the cover plate 1. Here, "lower" refers to the area below the temple 3 when the smart glasses are worn by the user, and "rear" refers to the direction of the temple 3 away from the frame.

[0039] Reference Figure 5 Based on the requirements of the sound emission direction, in order to keep the structure of the sound cavity cover simple, from the perspective of the structural form of the sound emission section 13, it is preferable that the sound emission section 13 is a hole structure. From the perspective of the number of sound emission sections 13, there are two sound emission sections 13. From the perspective of the layout of the sound emission sections 13, one sound emission section 13 is located at the lower rear side of the cover plate 1, and the other sound emission section 13 is located at the lower rear side of the cover plate 1. In this way, the two sound emission sections 13 are concentrated at one corner of the cover plate 1. At this time, only one sound transmission section 12 and one sound path block 2 need to be set. That is, one sound transmission channel will connect the two sound emission sections 13.

[0040] As mentioned above, the receiver 11 and the transmitter 12 are connected by a side wall. There are two types of connection: first, the receiver 11 and the transmitter 12 are connected by one of their respective side walls; second, the receiver 11 and the transmitter 12 are connected at the junction of their respective two side walls. In other words, the connection between the transmitter 12 and the receiver 11 is located at one corner of the groove structure. Considering the compactness of the acoustic cavity cover, the second type is preferred.

[0041] Reference Figure 5 As mentioned above, a gap is needed between the sound path block 2 and the bottom of the sound transmission section 12 to form a sound transmission channel. To more easily create this gap, a pad 121 is provided at the bottom of the sound transmission section 12. The pad 121 abuts against the surface of the sound path block 2 near the bottom of the sound transmission section 12, creating a gap between the sound path block 2 and the bottom of the sound transmission section 12. In this way, the sound path block 2 will not fall directly into the bottom of the sound transmission section 12, and the sound transmission channel is formed by the support of the pad 121 on the sound path block 2. At the same time, since the sound transmission section 12 is a groove structure, after the cover plate 1 is connected to the outer shell of the temple 3, the sound path block 2 is not fixed to the inner wall of the sound transmission section 12, and the sound path block 2 will not fall off the cover plate 1.

[0042] In other embodiments, if it is not convenient to form a pad 121, the acoustic path block 2 is fixed with glue at a position that is spaced from the bottom of the groove of the sound transmission part 12.

[0043] Reference Figure 5Based on the structure of the pad 121 formed in the sound transmission part 12, considering the difficulty of forming the cover plate 1, it is easiest to place the pad 121 at the edge of the bottom of the groove of the sound transmission part 12. However, if it is located at the edge, one pad 121 is not enough to stably support the sound path block 2. At this time, at least two pads 121 need to be provided. In the case of two pads 121, the two pads 121 are respectively located at the two bottom edges of the groove where the sound transmission part 12 and the sound receiving part 11 are connected, that is, the two bottom edges of the groove closest to the position where the sound transmission part 12 and the sound receiving part 11 are connected.

[0044] In summary, this application uses a cover plate 1 and an acoustic block 2 made of metal materials to form a non-linear sound transmission channel, so as to make the output sound quality better and more three-dimensional, while also providing waterproof and dustproof functions without obstructing the sound output.

[0045] This application also discloses a temple, which includes the acoustic chamber cover and the main body shell mentioned in the previous embodiments. The main body shell is made of plastic, and the acoustic chamber cover is made of metal. This material combination achieves lightweighting and wearing stability of the temple.

[0046] This application also discloses a smart glasses, which includes the acoustic cavity cover mentioned in the foregoing embodiments.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
