Логическая сборка динамика FAW: The 6 Ключевые компоненты для превосходной аудиосистемы в кабине

Welcome to this in-depth technical breakdown of the Логическая сборка динамика FAW. Это полный, 4-speaker component audio system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. Эта сборка является “голос” грузовика, responsible for translating electrical signals from the cab’s infotainment unit into clear, audible sound for the driver, covering everything from music and phone calls to critical system alerts.

The “Логическая сборка” designation is crucial. Это не одна часть, but a multi-component system based on an advanced acoustic “логика.” The Логическая сборка динамика FAW является а “компонент” система, meaning it separates audio frequencies across different, specialized speakers. This design is far superior to cheap “coaxial” ораторы, as it uses two dedicated full-range speakers for high/mid frequencies and two dedicated low-frequency speakers (woofers) for bass.

This component-based logic ensures maximum audio clarity and reduced distortion. This guide is essential for audio technicians and parts specialists. Мы разберем всю Логическая сборка динамика FAW в свой 6 ключевые типы компонентов, analyzing the two types of speakers and the specific fastening system that makes this assembly reliable in a high-vibration truck environment.

Основной 1: The Clarity Drivers – Full-Range Speakers (МГУ 1 & 2)

This section, а “дольше” module of our analysis, covers the most critical components for audio clarity in the Логическая сборка динамика FAW. These are the ‘Left full-range speaker assy’ (7901015-А01) and the ‘Right full-range speaker assy’ (7901020-А01).

Acoustic Logic (Mids & Highs): А “full-range” speaker is designed to produce the middle and high frequencies (mid-range and treble). This is where the human voice, string instruments, and cymbals “live” in a piece of music. В Логическая сборка динамика FAW, their “логика” заключается в предоставлении четкого, crisp sound stage for the driver.

Stereo Imaging and Placement: Having a separate ‘Left’ и «Правильно’ speaker is the foundation of stereo sound. These speakers are typically mounted high up in the cab, either in the A-pillars (the pillars beside the windshield) or in the upper corners of the dashboard, aimed at the driver. Этот “staging logic” намеренно. By placing these directional speakers at ear-level, а Логическая сборка динамика FAW создает “sound stage” that appears to be directly in front of the driver, rather than at their feet. This is essential for understanding navigation prompts and phone calls.

Строительство: These speakers are Minimum Serviceable Units (МГУ). Each assembly consists of several parts:

• The Cone: Usually made of a stiff, lightweight material like treated paper or polypropylene. This material must be durable enough to resist the extreme temperature swings and high humidity found inside a truck cab.
• The Surround: A flexible ring (often rubber or foam) that attaches the cone to the basket. It allows the cone to move back and forth, creating sound waves.
• The Voice Coil & Магнит: Это “мотор” of the speaker. The audio signal from the head unit flows into the voice coil, which becomes an electromagnet that moves within the permanent magnet’s field, pushing and pulling the cone.
• The Basket: A rigid frame (plastic or stamped metal) that holds all the parts together and provides the mounting points.

Удобство обслуживания (МГУ): These are high-wear items. The most common failure is a “blown” voice coil, caused by overpowering the speaker (turning the volume up too high with distortion). This results in no sound or a “scratchy” звук. The surround can also tear or decay, causing a “жужжащий” или “flapping” шум. As an MSU, a technician diagnoses the failed speaker and replaces the single unit (7901015-A01 or 7901020-A01), not the entire Логическая сборка динамика FAW.

Основной 2: The Bass Drivers – Low-Frequency Speakers (МГУ 3 & 4)

This is the second half of the acoustic “логика.” The ‘Left low-frequency speaker assy’ (7901025-А02) and ‘Right low-frequency speaker assy’ (7901030-А02) are the woofers.

Acoustic Logic (Lows): The “логика” of these speakers is to handle only the low-end frequencies (bass and mid-bass). Bass frequencies require moving large amounts of air, which is why these speakers (woofers) are physically larger, with more robust magnets and wider surrounds than their full-range counterparts.

Placement and Component Logic: These speakers are almost always mounted low in the truck doors. Bass is non-directional, so placement is less important for “staging.” The door panel itself acts as a large “enclosure” или “baffle,” which is necessary for the speaker to produce deep, rich bass tones.

Этот “компонент” separation is the most important feature of the Логическая сборка динамика FAW. The head unit’s amplifier has a “crossover” that sends *only* bass signals (НАПРИМЕР., below 200 Hz) to these woofers and *only* high signals (выше 200 Hz) to the full-range speakers. Этот “логика” prevents the small full-range speakers from trying to produce bass (which they can’t do well), resulting in dramatically cleaner, louder sound without distortion.

Удобство обслуживания (МГУ): Like the full-range speakers, these are primary MSUs. They are even more prone to failure from distortion, as bass notes carry the most power. А “треск” sound at high volume is a sign of the voice coil hitting its limit. А “жужжащий” sound is often a sign of a loose mounting screw or a separating surround.

Основной 3: The Fastening System Logic (МГУ 5 & 6)

A speaker is a vibration-creating device. Монтажное оборудование для Логическая сборка динамика FAW is therefore not just an afterthought—it is a critical system designed to manage that vibration. Список требует 16 screws and 16 washers.

1. ‘Саморезный винт с потайной головкой и крестообразным шлицем’ (CQ2714216): The parts list calls for sixteen (16) из этих. The “саморез” logic means they are designed to cut their own threads into the plastic of the door panel or dashboard. The quantity (16) confirms a robust 4-point mounting pattern for each of the four speakers.

2. «Шайба’ (Q40105): The list also calls for sixteen (16) washers. This is arguably the most important “логика” in the fastening system. A speaker’s frame is often made of plastic. A screw head creates a small, high-pressure point. The washer’s logic is twofold:

• Распределение нагрузки: It spreads the screw’s clamping force over a wider area of the speaker’s plastic mounting flange, предотвращая его растрескивание.
• Демпфирование вибрации: It acts as a buffer between the metal screw and the speaker frame, и (if it’s a spring washer) обеспечивает постоянное напряжение. This prevents the screw from vibrating loose—the #1 причина “грохот” ораторы.

These tiny, low-cost components are critical MSUs. Using the wrong screw or forgetting the washer will result in a failed installation, poor bass response (due to an air leak), and eventual rattling.
