**课程名称：** 声学101：扬声器设计基础与箱体设计 **课程概述：** 本课程旨在教授学员如何为扬声器设计合适的箱体。课程强调，不存在“最佳”的箱体设计，最终选择应取决于您的应用场景和个人偏好。您需要明确自己对音质的需求，例如：追求响度、偏好深沉低音而非响度，还是希望声音平滑线性？这些都需要在设计前明确。最终的箱体设计将是声学特性和个人喜好的权衡。您将是决定哪些音质更重要的“调音师”。 **课程内容：** 1. **声学基础：** * 课程从基础声学知识讲起，介绍声波的产生、传播及其特性。 * 随后深入探讨扬声器的设计原理及其他相关声学知识。 * 内容适合初学者，也能为有一定基础的学习者提供更清晰的理解。 2. **箱体类型：** * 介绍多种常见箱体类型，阐述其工作原理、优缺点。 * 重点深入讲解密闭式箱体（Sealed Enclosure）和倒相式箱体（Bass Reflex Enclosure）。 * 详细介绍这两种箱体的设计方法，包括标准对齐方式和自定义响应曲线。 3. **建模软件：** * 教授两种方法来模拟箱体的响应曲线和计算箱体尺寸： * **Excel电子表格：** 提供一个易于使用的电子表格工具，包含设计密闭式或倒相式箱体所需的一切，并能显示频率响应图，是初学者的完整解决方案。 * **专业软件：** 推荐付费软件“Subwoofer Design Toolbox”，因为其价格合理、界面简洁、易于理解且功能齐全，适合初学者循序渐进地学习。 **更新记录：** * 2017年11月：新增2路扬声器制作示例及基础2路分频器设计。 * 2018年1月：提供英文字幕。 * 2020年7月：部分课程增加了更多动画效果。
Design an enclosure to match your preferencesThe main purpose of this course is to teach you how to properly design an enclosure for your speaker. There is no such thing as "This enclosure is the best choice for this particular speaker". You have to take into consideration your application and your personal preferences. Do you want it to sound loud? Do you want it to sound deep and don't care about loudness? You want it to be as smooth and linear as possible? These are all just a few examples of questions that needs answering before you get to work. The final result will always be a compromise between the acoustical qualities of an enclosure. Only you can decide which sound qualities are more important to you and you should be the one who "moves the sliders".Acoustics basicsThis course assumes that you have minimal knowledge about acoustics, and therefore starts slowly with some basic information about sound waves, how they are created and what are their characteristics. Then moves on to how the speaker is designed and some other relevant information about acoustics. This is obviously needed for a beginner, but it's also good for an intermediate student, as I'm sure he will also find new information to make matters even more clear.Enclosure typesMost of the common enclosure types are listed, explaining their working principle, pro's and cons for each one. But, we will focus our attention for the sealed and bass reflex enclosures. These are covered with extensive details regarding their characteristics and how to design them according to the standard alignments, or to complete custom response curves.Modeling softwareTo model the response curve of the enclosure and to calculate the dimensions of the box, two methods will be used. You will receive an excel spreadsheet, that has all that you need to model a sealed or a bass reflex enclosure with minimal difficulty. It even has a chart to show you the modeled frequency response. It's basically a complete package for a beginner. The other method is by using a paid application. There are a lot of speaker design software solutions out there but I chose: "Subwoofer design toolbox". The main reasons are: it's cheap, simple, easy to understand and it has all the basic functions. If you are a beginner it's very important to start slow, otherwise you will get overwhelmed by complicated applications with extra features that will only confuse you.Nov 2017 Update - 2-way speaker build example and basic 2-way crossover design.Jan 2018 Update - Added English subtitles.Jul 2020 Update - Added more animation to some lessons.
