Description

Technical Field

[0001] This utility model relates to the field of smart glasses technology, and in particular to a sound transmission earpiece for smart glasses and smart glasses. Background Technology

[0002] Currently, smart glasses typically use an open-back design for audio output. This means the speaker unit is located inside the temple near the ear, with a sound hole at that position. The audio signal is transmitted through the air to the ear. Because this open-back design lacks a directional system, ambient noise mixes with the audio, interfering with the smart glasses' audio playback and affecting sound quality.

[0003] Therefore, existing technologies need to be improved. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a sound transmission earrest for smart glasses and smart glasses, which aims to directionally transmit the audio emitted by the sound-generating unit on the temple of the smart glasses to the human ear canal, thereby avoiding or reducing the interference of environmental noise and improving sound quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, this utility model proposes a sound-transmitting earcup for smart glasses, comprising:

[0007] The fixing part has a receiving cavity inside, and the front and rear ends of the fixing part have openings that communicate with the receiving cavity;

[0008] The sound transmission part is a tubular structure with a hollow interior forming a sound guiding cavity. One end of the sound transmission part is connected to the fixing part, and the other end is provided with a sound outlet. The sound outlet is used to align with the ear canal opening of the human ear. One end of the sound guiding cavity is connected to the receiving cavity, and the other end is connected to the sound outlet.

[0009] In some embodiments, the sound transmission part includes a sound transmission tube, a connecting end disposed at the front end of the sound transmission tube, and an ear-mounted end disposed at the rear end of the sound transmission tube. The connecting end is connected to the fixing part, and the sound outlet is formed on the inner sidewall of the ear-mounted end.

[0010] In some embodiments, the sound transmission tube is an arc-shaped bend, and the line connecting the connecting end and the earpiece end forms an angle with the transverse axis of the fixing part in the front-back direction.

[0011] In some embodiments, the included angle ranges from 10 to 50 degrees.

[0012] In some embodiments, the ear-mounted end of the sound transmission part is provided in the shape of a disc, and the inner side of the disc-shaped ear-mounted end is provided with a contact plane.

[0013] In some embodiments, the inner wall of the sound-conducting cavity of the sound transmission part is provided with a bending shaping piece.

[0014] In some embodiments, the bending and shaping sheet is a copper sheet.

[0015] In some embodiments, the bending and shaping sheet is tubular, and the inner wall surface of the tubular bending and shaping sheet is provided with a flocking layer.

[0016] Secondly, this utility model also proposes a smart glasses, which includes the aforementioned sound-transmitting ear rest for smart glasses.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a quick-release connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0035] refer to Figures 1 to 3 This utility model provides a sound-transmitting earpiece 100 for smart glasses, including a fixing part 1. The fixing part 1 has a receiving cavity 10. Openings communicating with the receiving cavity 10 are provided at both the front and rear ends of the fixing part 1. In this embodiment, the openings include a front opening 11 and a rear opening 12. The receiving cavity 10 is used to accommodate the temple portion of the smart glasses equipped with a sound-generating unit, enclosing this portion. The fixing part 1 has a top wall 13 at the top of the receiving cavity 10, which has a covering function. The front opening 11 and the rear opening 12 are used for the insertion of the temple of the smart glasses. The shape and size of the two openings of the fixing part 1, namely the front opening 11 and the rear opening 12, can be adaptively designed according to the shape and size of the temple. For example, in this embodiment, the front opening 11 is larger than the rear opening 12 to accommodate the installation and fixation of the temple with the sound-generating unit. The lower end of the fixing part 1, i.e. the lower part of the accommodating cavity 10, is used to transmit audio. When the temple is installed in the fixing part 1, the upper part of the temple is covered and blocked by the top wall 13. Because the front and rear sides of the temple are tightly fitted with the front opening 11 and the rear opening 12 of the fixing part 1, the sound emitted by the sound unit on the temple will not be transmitted from the front opening 11 and the rear opening 12. The sound emitted by the sound unit on the temple can only be transmitted from the lower part of the accommodating cavity 10.

[0036] It also includes the sound transmission section 2, such as Figure 3 As shown, the sound transmitting part 2 is a tubular structure with a hollow interior forming a sound guiding cavity 20. One end of the sound transmitting part 2 is connected to the fixing part 1, and the other end is provided with a sound outlet 3. The sound outlet 3 is used to align with the ear canal opening of the human ear. One end of the sound guiding cavity 20 is connected to the receiving cavity 10, and the other end is connected to the sound outlet 3. In this embodiment, as... Figure 1 As shown, the fixing part 1 and the sound transmission part 2 are integrally formed. The upper end of the sound transmission part 2 is connected to the lower end of the fixing part 1, and the lower end of the sound transmission part 2 is provided with a sound outlet 3. In this way, after the sound emitted by the temple sound unit is transmitted from the bottom of the housing cavity 10, it can only be transmitted in the sound transmission part 2 along the sound guide cavity 20 to the sound outlet 3 that is aligned with the human ear canal. In this way, the audio emitted by the temple is only transmitted inside the sound transmission part 2 and is not exposed to the external environment, which greatly reduces the interference of external noise and greatly improves the sound quality transmitted to the human ear.

[0037] The fixing part 1 and the sound transmission part 2 in this embodiment can be made of soft, deformable plastic or other materials.

[0038] Specifically, such as Figure 2 and Figure 3 As shown, the sound transmission part 2 includes a sound transmission tube 21, a connecting end 22 disposed at the front end of the sound transmission tube 21, and an ear-mounted end 23 disposed at the rear end of the sound transmission tube 21. The connecting end 22 is connected to the fixing part 1, and the sound outlet hole 3 is formed on the inner side wall of the ear-mounted end 23. In this embodiment, the sound guiding cavity 20 is formed by the internal cavity of the sound transmission tube 21. In this embodiment, the connecting end 22 of the sound transmission part 2 is disposed at the upper front end of the sound transmission tube 21 and connected to the lower end of the fixing part 1, thereby enclosing the lower end of the accommodating cavity 10 of the fixing part 1, thereby guiding the sound emitted by the temple sound-emitting unit downward into the sound transmission tube 21. In this embodiment, the connecting end 22 of the sound transmission part 2 receives the audio from the temple, then conducts it in the sound transmission tube 21, and then transmits it out from the sound outlet hole 3 of the ear-mounted end 23, forming a closed path for audio transmission and reducing interference from the external environment. Meanwhile, in this embodiment, the ear-mounted end 23 is located at the lower rear end of the sound transmission tube 21, so when using the sound transmission ear support 100 of this embodiment, the fixing part 1 is located in front of the ear, which makes it easy to wear.

[0039] In this embodiment, as Figure 4 As shown, the sound transmission tube 21 is an arc-shaped bend. The arc-shaped bend makes the transition between the conductive part 2 and the fixing part 1 more natural and aesthetically pleasing. The line connecting the connecting end 22 and the ear-mounted end 23 forms an angle α with the horizontal axis of the fixing part 1 in the front-back direction. The angle α is set to accommodate the assembly of the fixing part 1 with the temple and to conduct audio to the ear canal. Preferably, the angle α ranges from 10 to 50 degrees. Different angles α result in different lateral distances from the fixing part 1 to the ear, thus meeting different styling and wearing requirements.

[0040] Preferably, such as Figure 4 As shown, the ear-mounted end 23 of the sound transmission part 2 is shaped like a disc. A contact surface 231 is provided on the inner side of the disc-shaped ear-mounted end 23, and a sound outlet 3 is located in the center of this contact surface 231. The disc-shaped ear-mounted end 23 flattens the end of the sound transmission tube 21, facilitating the placement of the contact surface 231. The placement of the contact surface 231 allows the ear-mounted end 23 to fit tightly against the ear canal opening, thereby reducing interference from external noise to the sound outlet 3 and the ear canal opening.

[0041] Preferably, such as Figure 3 and Figure 5 As shown, the inner wall of the sound-conducting cavity 20 of the sound transmission section 2 in this embodiment is provided with a bending shaping piece 4. The bending shaping piece 4 bends and deforms after being subjected to force, and maintains the bent state without springing back. In this way, the user can adjust the relative bending angle between the inner and outer sides of the sound transmission tube 21, that is, adjust the contact angle between the ear-contact end 23 and the ear, so that the contact angle between the ear-contact end 23 and the ear is more comfortable.

[0042] As one embodiment, the bending and shaping sheet 4 is a copper sheet, which is durable and not easy to rust. Alternatively, in other embodiments, the bending and shaping sheet 4 can also be made of materials that can be bent and shaped, such as alloys.

[0043] In this embodiment, the bending shaping sheet 4 and the sound transmission part 1 can be combined using an injection molding process.

[0044] Furthermore, such as Figures 5 to 7 The bending and shaping piece 4 shown is tubular, and the inner wall surface of the tubular bending and shaping piece 4 is provided with a flocked layer 5. The tubular bending and shaping piece 4 can fit the inner wall of the conducting tube 21. Thus, when the inner wall surface of the tubular bending and shaping piece 4 is provided with a flocked layer 5, it is equivalent to the inner wall surface of the sound guiding cavity 20 being wrapped with a layer of flocked material. The flocked material on the flocked layer can absorb and filter noise, making the sound quality of the audio transmitted from the sound outlet 2 more beautiful.

[0045] The flocking layer uses synthetic fibers such as nylon, viscose, and polyester as the flocking material, and polyester fiber, nylon fiber, or cotton base fabric as the base material.

[0046] like Figure 5 and Figure 6 As shown, the bending shaping piece 4 in this embodiment is a half-tube shape, including a larger opening head end 41 and a smaller opening tail end 42 adapted to the shape of the sound transmission tube 21, as well as a tube wall 43. In other embodiments, the bending shaping piece 4 can be a complete tube shape, which can completely cover the inner wall of the sound transmission tube 21. This is equivalent to the entire cavity wall surface of the sound guiding cavity 20 being wrapped with a flocked layer 5, greatly increasing the area of ​​the flocked layer 5, which can better absorb noise.

[0047] This utility model also proposes a smart glasses, including the aforementioned sound-transmitting earpiece 100 for smart glasses. Since the smart glasses have the aforementioned sound-transmitting earpiece 100, the smart glasses have the aforementioned sound transmission effect, which will not be elaborated further here.

[0048] The above description is merely an example to clearly illustrate the present utility model and is not intended to limit the patent scope of the present utility model. It is impossible to exhaustively list all the embodiments here. All equivalent structural transformations made using the content of the technical solution of the present utility model under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
