【先前技術】 別是: 使其: 干擾防ϊ隻之送話器者。 按’隨著無線通訊科技的發達,現代人的溝通方式有 了長足的進步,而送話器更是通訊器材中不可或缺的元件 之一’送話器話質的穩定與體積的縮減亦是業界開發研究 的重點; 請參閱台灣專利公告第5 2 2 7 4 5號,『製造電容 式麥克風的方法』,由該案第一圖所示可知,習用電容式 送話器主要係以鋁或其它金屬形成一具有音孔的外殼,配 ^ 木座間隔出適當的空間’並將隔膜、隔膜環、塾圈斑 背孔板置入其中形成電容器,最後以設有晶體之印刷電路 板做為底盍’與外殼娜合’令送話器内部各元件封入殼體 中,藉由上述之結構,使聲波可由音孔傳入,當隔膜受到 聲波拍擊時便產生電壓變化,以電壓訊號傳輸至晶體,經 由晶體將該訊號放大,而傳輸至外部的聲音訊號端。 然,此種習用之電容式送話器無法避免地會有以下缺 失: 1 、以金屬材質做為送話為之设體者,由於金屬普遍 隔熱效果差,故送話器内部之元件容易受溫度變化之影響 ’而降低送話器之靈敏性。[Prior art] Don't: Make it: Interfere with the microphone of the microphone. According to 'With the development of wireless communication technology, modern people's communication methods have made great progress, and the microphone is one of the indispensable components in communication equipment.' The stability of the microphone quality and the reduction in volume have also It is the focus of research and development in the industry; please refer to Taiwan Patent Bulletin No. 5 2 2 7 4 5 "Method of Manufacturing Condenser Microphone". As shown in the first picture of the case, the conventional condenser microphone is mainly made of aluminum. Or other metal to form a shell with a sound hole, with a wooden seat to separate the appropriate space ', and insert the diaphragm, diaphragm ring, and ring-shaped back hole plate into the capacitor, and finally use a printed circuit board with crystals For the bottom of the case, the inner components of the microphone are sealed in the housing. With the above structure, the sound waves can be transmitted through the sound hole. When the diaphragm is struck by the sound waves, a voltage change is generated. The signal is transmitted to the crystal, the signal is amplified through the crystal, and transmitted to the external sound signal terminal. However, this conventional condenser microphone will inevitably have the following defects: 1. For those who use a metal material as the microphone, the components inside the microphone are easy due to the generally poor thermal insulation effect of metal. Affected by temperature changes', reducing the sensitivity of the microphone.

2、在送話器等無線通訊哭姑说、心 代為材逐漸朝向高頻、高霤斂 度、高整合度發展的同時,電磁μ 用回Α敏 丁 电磁干擾的問題亦逐漸受到重 視,習用之送話器並無法對電磁+掉^ + 刊又巧垔 ^ J电磁干擾做有效的防護,因此 勢必無法滿足使用者之需求。 3、習用之送話器受限於結構,故多採用單一組裝之 方式,如此不僅需要較多的人工操作,且良率亦較低,再 者,以鉚合方式組裝之送話器,會使殼體結構略為變形, 導致表面電荷不穩定,因此習用送話器在出廠之前必須再 多經過一道老化程序,使其表面電荷穩定。 、 因此就整體而言’其可說是相當地不具有實用性,實 有加以改良之必要。 【新型内容】 本創作之主要目的在於提供一種電容式陶瓷基板送話 器’其可改善習用電容式送話器之結構不易生產,且易受 溫度影響送話器靈敏度及電磁干擾防護效果不佳等缺失。 為達成前述之創作目的,本創作係利用陶瓷製成上基板、 定位基板及下基板’並將其貼合做為送話器之架構及殼體 ’利用聲波拍擊振動膜而使振動膜與極板所形成之電壓值 產生變化’並將電壓訊號輪出至晶體,放大訊號後並傳輸 至外部的聲音訊號端。 如下就本創作電容式陶瓷基板送話器,作一整理論述 ’俾使審查委員對本創作獲致更進一步之瞭解: 1 、利用陶瓷隔熱耐熱之特性,使送話器内部之電特 性不易文到影響,故可維持送話器之靈敏性。2. While wireless communication such as microphones cried, the mind generation gradually developed towards high frequency, high degree of convergence, and high integration. At the same time, the problem of electromagnetic interference from the use of electromagnetic μ back to Amin Ding gradually received attention. The microphone can't effectively protect against electromagnetic interference, ^ + journals and ^ J electromagnetic interference, so it is bound to fail to meet the needs of users. 3. Conventional microphones are limited in structure, so they are mostly assembled in a single way. This not only requires more manual operations, but also has a low yield. Furthermore, microphones assembled by riveting will The shell structure is slightly deformed, causing the surface charge to be unstable. Therefore, the conventional microphone must undergo an additional aging process before it leaves the factory to stabilize its surface charge. Therefore, as a whole, it can be said that it is not very practical and it is necessary to improve it. [New content] The main purpose of this creation is to provide a capacitive ceramic substrate microphone, which can improve the structure of conventional capacitive microphones, is difficult to produce, and is easily affected by temperature. Microphone sensitivity and electromagnetic interference protection are poor. Etc. Missing. In order to achieve the above-mentioned creative purpose, this creative work uses ceramics to make the upper substrate, positioning substrate and lower substrate, and attaches them to the structure and housing of a microphone. The voltage value formed by the electrode plate changes, and the voltage signal is output to the crystal, and the signal is amplified and transmitted to the external sound signal terminal. The following is a compilation and discussion on the creation of the capacitive ceramic substrate microphone. 'This will enable the review committee to gain a better understanding of this creation: 1. Use the characteristics of ceramic heat insulation and heat resistance to make the electrical characteristics inside the microphone difficult to understand. Effect, it can maintain the sensitivity of the microphone.
