本實用新型涉及一種壓電蜂鳴器,尤其涉及一種防水的蜂鳴器。背景技術:壓電蜂鳴器是用于家用電器的一種發(fā)聲報警裝置,通常由固定在蜂鳴盒中的蜂鳴片、與該電連接的兩個電極構成。目前,由于蜂鳴片的表面沒有設置保護層,容易進水導致內部壓電結構不穩(wěn)定,致使發(fā)聲質量下降。技術實現(xiàn)要素:為了克服現(xiàn)有技術中存在的缺陷,本實用新型提出一種防水的蜂鳴器。一種防水的蜂鳴器,所述蜂鳴器包括蜂鳴片和蜂鳴盒,所述蜂鳴片由金屬板和壓電陶瓷片構成,所述蜂鳴片設置于蜂鳴盒中,所述蜂鳴盒兩側引出蜂鳴片的電極;所述蜂鳴片外部包裹一層襯底,所述襯底和蜂鳴盒之間填充防水材料;所述蜂鳴盒上設有排水孔,與防水材料配合使蜂鳴盒內保持干燥。進一步地,所述襯底采用聚氨酯材料。進一步地,所述襯底里面具有空芯的結構。本實用新型的有益效果為:通過防水材料和排水孔的設置保證了蜂鳴盒內部的干燥和及時排水。所述襯底是聚氨酯材料制成的,具有耐老化、具有彈性延展性包裹性好的優(yōu)點。同時,襯底采用空芯的結構,成本低。如果蜂鳴器是作為高聲壓報警用的,普通的兩引腳電感還不能滿足要求。無錫接觸器AD16系列蜂鳴器推薦廠家
更低功耗、更快靜態(tài)成像、更小相機模塊尺寸,以及更高容量和更高視頻數(shù)據(jù)幀速率,將是其圖像信號處理器的用武之地。除此之外,人機界面(HMI)設備的趨勢與發(fā)展成果,也在富士通半導體相關芯片方案中得到體現(xiàn),這些HMI設備利用2D及3D技術,以虛擬化圖像呈現(xiàn)達到提升設備性能、質量及用戶體驗的目的。為了復雜儀表板產(chǎn)品的開發(fā),擁有掌控未來商用車市場先進理念、HMI開發(fā)以及客戶預期的能力,是富士通半導體意圖所在。理器性能提升與存儲器的優(yōu)化搭配密不可分,而非易失性、高速讀寫及高耐久性、功耗是FRAM的特點,則在迎合高速、低功耗移動互聯(lián)應用上優(yōu)勢明顯。FRAM利用鐵電晶體的偏振極化特性實現(xiàn)數(shù)據(jù)存儲,其特點是速度快,能夠像RAM一樣操作,讀寫功耗極低,而且不存在如E2PROM的比較大寫入次數(shù)的問題。而富士通半導體的FRAM量產(chǎn)技術所制造的FRAM產(chǎn)品以非易失性、高速燒寫、高讀寫耐久性上萬億次、隨機存儲以及低功耗等諸多優(yōu)點在FRAM產(chǎn)品中脫穎而出。目前,富士通半導體FRAM產(chǎn)品容量覆蓋從4Kb到4Mb,而且還在著手研發(fā)8Mb產(chǎn)品,逐步實現(xiàn)大容量化。若按接口類型則分為三類:串行I2C接口、串行SPI和并行接口產(chǎn)品。富士通半導體的規(guī)劃是。虹口區(qū)AD16系列蜂鳴器費用是多少節(jié)點支持方式-將蜂鳴片固定于約與陶瓷片直徑同尺寸的環(huán)形結構內。
