Description
本發明係有關一種應用於平面揚聲器之複合材料懸樑式片狀激震器之製造方法,為一種藉由塑膠射出成型之製造方法,利用對合之左模具及右模具成型構造,使音圈及懸樑包覆於片體與固定座之立柱間,形成一體成型之複合材料懸樑式片狀激震器者。The invention relates to a manufacturing method of a composite cantilever type plate shock absorber applied to a flat speaker, which is a manufacturing method by plastic injection molding, which utilizes a right mold and a right mold forming structure to make a voice coil and a cantilever beam. It is wrapped between the sheet body and the column of the fixed seat to form an integrally formed composite cantilever type sheet shock absorber.
習用平面式揚聲器,如中華民國專利公告號200733034之「平板式揚聲器構造」,其採用非一體式之激震器設計,導致懸樑結構抗疲勞性不佳且缺乏結構簡化性與加工快速性,在產業應用上缺乏專屬性。Conventional flat-type loudspeakers, such as the "flat-panel speaker construction" of the Republic of China Patent Publication No. 200733034, which adopts a non-integrated shock absorber design, resulting in poor fatigue resistance of the suspension beam structure and lack of structural simplification and rapid processing in the industry. There is a lack of specificity in the application.
上述習用平面式揚聲器之最大的缺點在於:The biggest disadvantages of the above-mentioned conventional flat speakers are:
1.激震懸臂非一體式結構,其強度及耐疲勞度明顯不足,大幅降低使用壽命與品質可靠度。1. The non-integrated structure of the shock cantilever is obviously insufficient in strength and fatigue resistance, which greatly reduces the service life and quality reliability.
2.激震懸臂非一體式結構,會增加結構元件數與複雜程度,在組裝上增加工時及生產成本。2. The non-integrated structure of the shock cantilever will increase the number and complexity of the structural components, and increase the man-hour and production cost in assembly.
3.無法承受較大之揚聲器往復震動之驅動力,影響揚聲器之有效輸出功率及聲音輸出之品質。3. Can not withstand the driving force of the large speaker reciprocating vibration, affecting the effective output power of the speaker and the quality of the sound output.
上述所提及關於習用之平面式揚聲器,儘管能夠達成在承受激震輸出方面所應具備之一般強度及耐疲勞基本要求與成效,但在實際應用時之輸出效能、耐疲勞壽命及產業應用專屬性上,皆存在諸多缺點與不足的情況下,無 法發揮更具體之產業應用性。The above mentioned planar loudspeakers for use, although able to achieve the general requirements and results of general strength and fatigue resistance required to withstand the shock output, but in practical applications, output efficiency, fatigue life and industrial application specificity On the above, there are many shortcomings and deficiencies, no The law exerts more specific industrial applicability.
另,發明人早前申請有中華民國新型專利公告號第M329304號「片狀激震器之構造」,該專利案已針對上述習知平面式揚聲器之缺失進行改良,其作用相當顯著,但發明人本著精益求精之精神,研發出以複合材料所製造之懸臂,而製成片狀激震器之方法者。In addition, the inventor earlier applied for the Republic of China New Patent Bulletin No. M329304 "Structure of a sheet-shaped shock absorber", which has been improved for the lack of the above-mentioned conventional flat-type speaker, and its effect is quite remarkable, but the inventor In the spirit of excellence, we have developed a method of making a sheet-shaped shock absorber by using a cantilever made of a composite material.
本發明係以解決習用平面式揚聲器在輸出效能、耐疲勞壽命及產業應用專屬性不足之缺點,以及在實用化技術等方面受到限制之問題,一方面在達成提升與強化激震輸出之結構疲勞強度為首要目的,另一方面在提升簡化設計、便於加工與組裝方面之功能性、適用性及應用範圍,以達成所應具備可承受激震輸出之一般強度及耐疲勞基本功能外,並使其兼具平面揚聲器產業應用性之實際發展與要求。The invention solves the defects that the conventional planar speaker has insufficient output performance, fatigue life and industrial application specificity, and is limited in practical technology, and on the other hand, achieves structural fatigue strength of lifting and strengthening shock output. For the primary purpose, on the other hand, to improve the functionality, applicability and application range of simplified design, ease of processing and assembly, in order to achieve the basic strength and fatigue resistance basic functions that can withstand the shock output, and to The actual development and requirements of the application of the flat speaker industry.
所以不論由主客觀條件觀之,用於平面揚聲器之複合材料懸樑式片狀激震器之製造技術與方法,在國內外專利中目前確實無相關結構技術應用,具備市場無可取代之高激震疲勞強度技術之優勢,極適合應用於高級平面揚聲器等設備市場,勢必可以帶來平面揚聲器設備生產與製造產業相關市場之莫大商機。Therefore, regardless of the subjective and objective conditions, the manufacturing technology and method of the composite cantilever type diaphragm shock absorber for flat speakers have no relevant structural technology application in domestic and foreign patents, and have high irresistible high shock fatigue in the market.
