Description

Technical Field

[0001] This utility model belongs to the field of entertainment equipment technology, specifically, it relates to a front frame of a jukebox. Background Technology

[0002] With the development of the entertainment industry, karaoke machines have become essential equipment in entertainment venues such as KTVs and bars. The front frame of the karaoke machine, as a crucial component, not only affects its appearance but also the user experience and the machine's practicality.

[0003] Utility model CN209374048U discloses a front frame of a karaoke machine, including a front frame body and side frames. The front frame body has an inner mounting groove, and a circuit mounting plate is installed inside the mounting groove. A side frame is installed outside the circuit mounting plate. A mobile phone placement slot is located on one side of the upper end of the side frame, and a water cup slot is located on the upper side of the side frame next to the mobile phone placement slot. A raised rib is installed on the outer side of the front frame body. Multiple heat dissipation holes are evenly spaced in the middle of the outer perimeter of the front frame body. Compression springs are installed inside both ends of the mobile phone placement slot, and a compression block is installed at the other end of each compression spring. A rubber pad is installed on the outer side of the compression block. This utility model, with its side frames installed on the outer side of the front frame body, facilitates the placement of mobile phones and water cups, improving the convenience of song selection. Furthermore, the raised ribs on the outer side of the front frame body enhance its impact resistance.

[0004] However, the aforementioned patents still have the following problems: especially for elderly users, although the front frame design provides ample functional areas, song selection still relies on a touchscreen or physical buttons. While the front frame design has taken impact resistance into account, the physical buttons exposed to the outside of the device are still susceptible to damage from impacts or external forces. After prolonged and frequent use, the button surface may wear down due to friction, affecting aesthetics and tactile feel; the internal mechanical structure may also fail due to fatigue, leading to button malfunction. Physical buttons are usually directly exposed to the outside of the device, making them vulnerable to accidental impacts or external forces, further shortening their lifespan.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content
