Description

Technical Field

[0001] The utility model relates to the field of door locks, in particular to a speaker assembly structure of a door lock. Background Art

[0002] In order to improve user experience and safety, existing door lock systems often integrate sound prompts, such as door lock opening and closing prompts or low battery warnings. These sound prompts are mostly implemented through speakers, and the speaker installation method has a significant impact on the sound effect, cost control, and installation convenience. Currently, there are two main methods for door lock speaker installation on the market:

[0003] One method is to directly assemble it to the front plate and fix it with screws. In this way, the speaker is directly mounted on the front plate or casing of the door lock and fixed with screws and other fasteners. Although this method is simple to operate, it has several significant disadvantages. First, because the speaker is directly attached to the front plate, there is a lack of sufficient sound cavity space, resulting in limited sound propagation and poor sound quality, especially in the low-frequency band. Secondly, the front plate is often used as the appearance of the door lock. Its material and thickness may not be conducive to the effective conduction of sound, further affecting the sound effect. Finally, drilling holes directly on the front plate to install the speaker may damage the overall aesthetics of the door lock and increase the difficulty and cost of processing.

[0004] Another approach is to use a speaker bracket as a sound chamber and secure it to the front panel: To improve sound quality, another common practice is to first design a speaker bracket that not only holds the speaker but also serves as a sound chamber to optimize sound propagation and resonance. This integrated speaker and bracket assembly is then secured to the front panel of the door lock. While this approach improves sound quality, its drawbacks are also significant. First, the design and manufacture of the speaker bracket incurs additional material and processing costs. Second, the entire installation process becomes more complex, requiring the speaker to be mounted on the bracket and then precisely aligned and secured to the front panel, which undoubtedly increases the difficulty and time required for installation. Finally, the additional bracket component may also restrict the internal spatial layout of the door lock, affecting the compactness and aesthetics of the overall design. Utility Model Content

[0005] The purpose of the present utility model is to solve the above technical problems and provide a speaker assembly structure for a door lock. The present application is to provide a speaker assembly structure that is easy to assemble, thereby ensuring the speaker sound effect while reducing the cost of the product.
