Description

Technical Field

[0001] This utility model relates to the field of loudspeakers, and in particular to a miniature loudspeaker with a teardrop-shaped appearance. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals, and its performance greatly affects sound quality. The loudspeaker is the weakest component in an audio system, yet it is also one of the most important components for achieving optimal sound effects. There are many types of loudspeakers, and their prices vary greatly. Audio electrical energy, through electromagnetic, piezoelectric, or electrostatic effects, causes the paper cone or diaphragm to vibrate and resonate with the surrounding air, thus producing sound.

[0003] For smart glasses, speaker integration is one of the key design considerations. Existing smart glasses speakers, such as Chinese Patent 202222176020.7, use detachable brackets to facilitate speaker installation and positioning. However, in actual products, the arms of smart glasses are generally not of uniform width, which wastes a lot of space and affects the sound quality of the speaker.

[0004] Especially for the arms of smart glasses, which are relatively narrow, ensuring the stable operation of the miniature speaker within a small volume is a key design consideration. Utility Model Content

[0005] The main purpose of this invention is to propose a miniature speaker with a water droplet shape, which aims to improve the existing speaker structure of smart glasses. It can ensure the stability of the structure and facilitate its installation and fixation. At the same time, a balance cavity is set in a small volume, thereby ensuring the internal pressure stability of the miniature speaker and ensuring stability.

[0006] To achieve the above objectives, this utility model proposes a miniature speaker with a teardrop shape, comprising:

[0007] The bracket, whose width gradually decreases from the inside to the outside, is divided into an expanding section and a contracting section;

[0008] The positioning cavity is located in the expanded diameter section and extends through the bracket. The bottom wall of the positioning cavity has an inwardly extending limiting portion for placing a speaker.

[0009] The side wall of the positioning cavity is provided with a sound outlet;

[0010] The balancing cavity is located in the reduced diameter section, and the balancing cavity and the positioning cavity are spaced apart and connected.

[0011] In practical design, after the speaker is mounted on the bracket, it can be directly installed inside the eyeglass arm. The bracket is preferably positioned at the ear hook, which allows the speaker's sound to be accurately transmitted to the ear, thereby reducing the amount of sound that needs to be emitted.

[0012] Of course, bone conduction speakers can also be used to effectively ensure accurate sound transmission;

[0013] The through-hole positioning cavity in the bracket effectively reduces the transmission of speaker resonance to the housing. Furthermore, the two-section bracket design ensures maximum speaker volume within a limited space, thus preventing the speaker from being too small and compromising sound quality.

[0014] The addition of a balance cavity can reduce the negative pressure that occurs after the bracket is installed inside the housing, which affects the sound quality. The balance cavity and the positioning cavity are closed structures after installation in the housing.

[0015] The placement of a sound hole within the positioning cavity effectively ensures precise sound transmission.

[0016] This application mainly concerns the speaker bracket, so the design of its magnetic circuit components and vibration components can be adjusted according to actual needs. Of course, the bracket can also be understood as a modular design. Attached Figure Description

[0028] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0029] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0031] like Figures 1 to 5 As shown, a miniature speaker with a teardrop shape includes:

[0032] The bracket 1 has a gradually decreasing width from the inside to the outside and is divided into an expanding section 11 and a reducing section 12.

[0033] The positioning cavity 2 is located in the expanded diameter section 11 and extends through the bracket 1. The bottom wall of the positioning cavity 2 has an inwardly extending limiting part 20 for placing the speaker.

[0034] The side wall of the positioning cavity 2 is provided with a sound outlet 21;

[0035] The balancing cavity 3 is located in the reduced diameter section 12. The balancing cavity 3 and the positioning cavity 2 are spaced apart and connected.

[0036] In practical design, after the speaker is installed in bracket 1, it can be directly installed inside the eyeglass arm. The bracket 1 is preferably positioned where the housing is located at the ear hook (i.e., at or adjacent to the ear), which allows the speaker's sound to be accurately transmitted to the auricle, thereby reducing sound dispersion.

[0037] Of course, bone conduction speakers can also be used to effectively ensure accurate sound transmission;

[0038] The bracket 1 has a through-hole positioning cavity 2, which can effectively reduce the resonance of the speaker transmitted to the housing. In addition, the two-section bracket 1 can ensure the maximum speaker volume in a limited space, thereby avoiding the impact of the speaker's sound quality on the size being too small. In terms of relative size, the larger the speaker size, the better the sound quality of its sound unit.

[0039] Meanwhile, the balanced cavity 3 can reduce the negative pressure that occurs after the bracket 1 is installed in the housing, which affects the sound quality. The balanced cavity 3 and the positioning cavity 2 form a closed structure after being installed in the housing.

[0040] The sound outlet 21 set in the positioning cavity 2 can also effectively ensure the accurate transmission of sound, and the side sound outlet method is adopted.

[0041] In this embodiment of the utility model, the side of the bracket 1 is teardrop-shaped and its outer peripheral wall has an arc transition, which can ensure a large space utilization rate. At the same time, the modular design of the bracket 1 makes it convenient to install and use.

[0042] Specifically, the sound outlet 21 is elongated and has a support 22 in the middle. In the actual structure, its overall size is small. Therefore, the small and thin sound outlet 21 is easily affected by vibration and resonant deformation, which in turn affects the user experience.

[0043] In this embodiment of the utility model, there are three limiting parts 20, one on the inner end of the expansion section 11, and two on the outer end of the expansion section 11 arranged symmetrically, which facilitates the installation of the speaker. Of course, the speaker can also be embedded or modular.

[0044] Specifically, the limiting part 20 is provided with an upwardly extending positioning post 23, which facilitates the installation and fixation of the speaker module.

[0045] In this embodiment of the utility model, the width of the positioning cavity 2 gradually decreases from the inside to the outside, and the two ends of the positioning cavity 2 are arc-shaped, thereby satisfying the installation of the speaker while increasing the outer diameter of the speaker.

[0046] Specifically, the balancing cavity 3 includes two spaced-apart first cavities 31 and second cavities 32. The first cavity 31 and the second cavity 32 are respectively provided with a first fluid channel 311 and a second fluid channel 312 that connect to the positioning cavity 2. The dual-cavity structure can effectively avoid the generation of negative pressure in the positioning cavity 2, thereby improving the sound quality of the speaker and changing the existing problem of needing to use a sound leakage hole to achieve the balancing of the positioning cavity 2.

[0047] In this embodiment of the utility model, the first cavity 31 and the second cavity 32 are configured with a reduced diameter from the inside to the outside.

[0048] Specifically, the first fluid channel 311 and the second fluid channel extend into the side wall and horizontal plane of the positioning cavity 2, respectively, thereby achieving internal pressure balance from different positions.

[0049] The first fluid channel and the second fluid channel are arranged in a bent shape.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
