Abstract
การปรับปรุงลำโพงแบบธรรมดาทั่วไปที่โครงของลำโพงมีช่องทะลุถึงกันได้ให้เป็นแบบเปิด (OPENINGS) โดยเมื่อมองจากรูป หน้าตัดจะเห็นรูปตัว V ต่อเนื่องกันไปตลอดประโยชน์จากรูป ตัว V นี้คือการช่วยลดการรบกวนของเหลี่ยม (NEGATIVE WAVES) ภายในตู้ลำโพง ตลอดจนปัญญาเสียงสะท้อนหรือเสียงก้อง (RESONANCE)ของตู้ลำโพงก็หมดไปด้วย นอกจากนี้ยังช่วยเพิ่ม ประสิทธิภาพให้แก่ระบบเสียงอีกด้วย อีกวิธีหนึ่งที่อาจทำ ได้ก็คือการปรับปรุงแก้ไขจานรูปตัว V ชนิดมีช่องเพื่อใช้ กรองหรือปรับระดับเสียงโดยอาศัยหลักการณ์เช่นเดียวกับที่ กล่าวมาข้างต้น เพื่อสำหรับไว้ใช้ในระบบกระจายเสียงทั่วไป หรือในเครื่องเก็บเสียง Improving the common speaker that the speaker frame has a through-hole to open (OPENINGS) when viewed from the picture. The cross-section will see a continuous V-shape throughout the benefit of this V-shape is to help reduce the interference of the square (NEGATIVE WAVES) inside the speaker cabinet. As well as wisdom, echo or echo (RESONANCE) of the speaker cabinet is also gone. It also improves Performance for the audio system as well Another way it might do It is possible to modify the V-shaped plate with a slot for use. Filter or adjust the volume based on the same principles as that. Above For use in general broadcasting systems Or in the silencer
