Abstract
Description
Technical Field
[0001] This utility model relates to the field of Bluetooth power amplifier controller technology, specifically to a Bluetooth power amplifier controller. Background Technology
[0002] A Bluetooth amplifier controller is a device that integrates Bluetooth technology and amplifier control functions.
[0003] The equipment in existing agricultural machinery is generally connected via cables, which increases the complexity of operation and may restrict the operator's freedom of movement and operational efficiency due to the constraints of the cables. Wired connections also limit the location of audio equipment, which may require the operator to place the audio equipment in a fixed position near the agricultural machinery, potentially affecting the operator's comfort and audio experience. Furthermore, remote control of the equipment is not possible, and existing controllers are generally installed and fixed directly with screws, leaving gaps on the sides of the mounting frame and resulting in poor sealing. Utility Model Content
