This invention belongs to the field of headphone technology, and specifically relates to a quick-release structure for a headphone battery with elastic contact. It includes: a sound-generating unit with a mounting groove containing a receiver, and at least two inductive elements; and a battery unit with a conductive plate located inside the battery unit. By placing the conductive plate inside the battery unit, leakage caused by contact between the battery electrodes and the external environment is prevented. When the battery unit needs to be placed on the sound-generating unit, the receiver contacts the conductive plate, thereby establishing circuit continuity. This allows for easy assembly and disassembly of the battery unit and the headphone's sound-generating unit. During assembly, simply placing the battery unit on the sound-generating unit allows for automatic alignment and circuit connection through physical contact, eliminating the need for soldering, ribbon cables, or connectors, significantly reducing the difficulty and cost of automated assembly.

This invention discloses a cashew nut shell bisphenol and its preparation method and application. The preparation method of the bisphenol is as follows: First, cashew nut shell phenol, formaldehyde, and an alkaline catalyst are mixed and stirred evenly, and reacted at a certain temperature to obtain hydroxymethylated product A; product A is washed with water several times until the pH is neutral, and then centrifuged to remove water to obtain product B; product B is mixed with phenol and an acidic catalyst and stirred evenly, and reacted at a certain temperature to obtain product C after the phenol-alcohol reaction; product C is washed with water until neutral, and then distilled under reduced pressure to obtain the cashew nut shell bisphenol product.
