商品描述

Introduction to Loudspeaker Design is written for students, technicians, engineers and hobbyists seeking an overview of the technology of loudspeakers. Starting with a brief history of audio developments the book begins by introducing the concepts of frequency, pitch and loudness and proceeds to develop the idea of a loudspeaker as a system. The book covers such topics as loudspeaker design tradeoffs, spatial loading, diffraction loss, cavity effect and enclosure construction. A complete chapter is devoted to the subject of crossover design including design equations. The second edition adds a new chapter on simulation and analysis which includes design equations for closed and vented type speakers. The appendices contain technical references, design aids, glossaries and a chart depicting 18 different loudspeaker enclosure types.

Changes for the Second Edition:
The second edition brings new material and polishes the first edition with many new or improved illustrations. Chapter 2 was expanded with the second half split into a new Chapter 3 titled "Speaker Response Functions". The discussion of Thiele-Small parameters has been expanded and now covers small-signal parameters vs. large-signal parameters as it explores the role of the test signal level in parameter measurement. The crossover design chapter has been expanded to include formulas for calculating component values for the most popular crossover types. Equations have been added for calculating impedance compensation and attenuation networks. The old Chapter 7 FAQ material was integrated into other chapters as appropriate. A new Chapter 8 titled "Loudspeaker Simulation" has been added and introduces loudspeaker equivalent circuit analysis with equations for calculating the magnitude and phase responses of closed and vented loudspeaker systems. Additional design equations are introduced and then examples are given for calculating the responses of a closed box and a vented box loudspeaker. Detailed design equation summaries are given for closed and vented boxes. Appendix C was added to provide a glossary of symbols and a glossary of terms. The box type charts were moved to Appendix D.

商品描述(中文翻譯)

《喇叭設計入門》是為了學生、技術人員、工程師和愛好者而寫的,旨在提供對喇叭技術的概述。書籍從音頻發展的簡要歷史開始,介紹了頻率、音高和音量的概念,並進一步發展了喇叭作為一個系統的概念。書籍涵蓋了喇叭設計的折衷、空間負載、繞射損失、腔體效應和外殼結構等主題。其中一個章節專門介紹了交叉設計,包括設計方程式。第二版增加了一個新章節,介紹了模擬和分析,其中包括閉式和通風式喇叭的設計方程式。附錄包含技術參考資料、設計輔助工具、詞彙表和描述18種不同喇叭外殼類型的圖表。

第二版的變動:
第二版增加了新的內容,並通過許多新的或改進的插圖完善了第一版。第2章的內容擴展,其中下半部分分為一個新的第3章,標題為“喇叭響應函數”。對Thiele-Small參數的討論進行了擴展,現在涵蓋了小信號參數與大信號參數,並探討了測試信號水平在參數測量中的作用。交叉設計章節擴展了計算最流行的交叉類型的元件值的公式。添加了計算阻抗補償和衰減網絡的方程式。舊的第7章常見問題解答材料已根據需要整合到其他章節中。增加了一個新的第8章,標題為“喇叭模擬”,介紹了使用等效電路分析計算閉式和通風式喇叭系統的幅度和相位響應的方程式。引入了額外的設計方程式,然後給出了計算閉式和通風式喇叭響應的示例。給出了閉式和通風式箱體的詳細設計方程式摘要。添加了附錄C,提供符號詞彙表和詞彙詞彙表。箱體類型圖表移至附錄D。
