Description

Technical Field

[0001] This utility model relates to the field of speaker grille technology, and in particular to a hinged structure for a speaker grille and a speaker. Background Technology

[0002] A speaker is a device that converts audio signals into sound. Simply put, it refers to a speaker enclosure or subwoofer enclosure with a built-in power amplifier that amplifies the audio signal before it is played back by the speaker itself, making the sound louder. Currently, many speakers on the market typically have a grille on the outside of the speaker body to decorate its appearance.

[0003] In related technologies, speaker grilles are typically constructed from two disassembled components joined together to form a barrel-shaped structure; the assembly of these two components usually takes two forms: The first type is the snap-fit ​​assembly scheme. When injection molding two parts, a male snap-fit ​​is installed on one part and a female snap-fit ​​is installed on the other part. The two parts are fixedly connected by their own male and female snap-fits. However, the defect of the snap-fit ​​assembly scheme is that when the two hard plastic male and female snap-fits are snapped together, they are not completely fixed. There is a certain assembly gap between the male and female snap-fits. When the speaker plays music, these assembly gaps will generate vibration, which will cause noise when the user uses it, resulting in a decrease in the overall sound quality of the speaker and a poor user experience.

[0004] The second method involves connecting two components using a hot-stamping process. The hinge is typically made of metal or plastic. One end of the hinge is welded to one component, and the other end is welded to the other component, thus securing the two components together. However, this method requires initially fixing the two components to the hinge before using a welding tool to heat a hot-melt column to completely bond the plastic of the hot-melt column to the hinge. Since the hot-stamping process is very time-consuming, its production efficiency is significantly lower compared to the first snap-fit ​​assembly method.

[0005] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content
