摘 要 手機是人與人之間直接溝通的工具之一,消費者在使用手機的過程中,除了射頻會影響聲音接收與傳送的清晰度外,手機本體對「聲音」迴路的設計所產生的「聲音」效果,更是直接影響聲音品質的主因。在保護「使用者的聽覺系統」的前提下,為了讓大量製造生產出來的手機聲音品質具有一致性與穩定性,就必須在生產過程中建立一套具有可信度的「手機音頻量測系統」,此系統所用到的相關設備治具的穩定性便是決定手機聲音品質穩定的關鍵因素,而設備治具的穩定性更是端賴「校驗」作業的確實執行來把關。 在既定的資源、已知條件與限制範圍下,有效利用品管七大手法、Gage R&R、ANOVA與數據分析工具Minitab,進行一系列的實驗探討與分析作業後,利用最後結果建構一套標準的設備治具的校驗模式,並期能將此模式成為A公司內部品質管理手法的常態作業流程之一,使A公司所研發與生產製造出來的手機品質更具保證性與安全性,期能為使用者在健康方面爭取更多的安全保障。
Abstract Mobile phone is one of the tools of communication between humans. During the usage of mobile phone, the design of acoustic circuitry is the main factor to affect the acoustic quality directly, except the performance of radio frequency. Under the prerequisite of protecting user’s sense of hearing, there must be a reliable measuring system of mobile phone acoustics established in production process in order to have consistent and stable quality of acoustics during mass production. In this system, the stability of related test fixtures is the key factor to keep the stability of acoustic quality of mobile phone. And the stability of test fixture relies on the execution of calibration process. Utilizing 7 techniques of quality control, Gage R&R, ANOVA and Minitab effectively to perform experiments and analysis, the standard calibration mode of test fixtures is established according to the final result. Hope this calibration mode could be adopted as one of the normal operation process of quality control in “A” company in order to design and produce more reliable and safe mobile phone for the users.
