In 1849, an Italian-born inventor developed an early device for voice communications but couldn't afford a full patent due to financial hardship, allowing Alexander Graham Bell to get it in 1876: How did Telettrofono changed the world?
1849 年,一位出生于意大利的发明家开发了一种早期的语音通信设备,但由于经济困难而无法获得完整的专利。安东尼奥·梅乌奇 (Antonio Meucci) 在亚历山大·格雷厄姆·贝尔 (Alexander Graham Bell) 获得电话专利之前几年就发明了 Telettrofono。经济困难、受伤和未支付的专利续展费影响了他的索赔。 2002 年,他的工作因帮助奠定了语音通信技术的基础而获得了美国众议院的认可。
