Internal Components of HTC NE11 Wireless Earphones

Overview

This document presents detailed internal photographs of the HTC NE11 wireless earphones, essential for FCC certification. The images reveal the disassembled device, focusing on the main printed circuit board (PCB) and the internal battery.

Main Circuit Board Details

The primary circuit board is clearly visible, marked with model information "LDN-869-V1.0" and a date code "25-01-16". A prominent integrated circuit (IC) is labeled with a frequency of "24.000 MHZ", indicating its radio frequency capabilities, likely for Bluetooth. Connection terminals for power and signals are labeled, including "+BAT" (battery positive), "V+", "V-" (voltage terminals), "S-", and "S+" (signal terminals). The board also displays the FCC ID: NE11 and a part number "BP20424-7304". The abbreviation "BLE" confirms the use of Bluetooth Low Energy technology.

The reverse side of the circuit board is also documented, showing solder points and component layout.

Battery Specifications

A compact, cylindrical battery is featured, identified by model numbers "301012" and "212503 J". It has a stated capacity of "240mAh" and is connected via thin wires, one pink and one green. The battery casing has a distinctive metallic gold finish.

Device Assembly and Identification

The photographs illustrate how the internal components are housed within the earphone structure. The circuit board is integrated into the earphone's design, connecting to the battery and other internal elements. The presence of "L:" and "R:" in the original document might refer to left and right earphone components, though this is not explicitly shown in the provided images.
