Abstract

一种无冲击噪音且可同步接收外界声响的耳塞式受话器,是于该受话器本体的内部空间中置放有一喇叭,而该受话器本体的前缘穿设至少有一出音孔,且该喇叭所置放的位置与该受话器本体前缘的位置两者间相距有一适当距离,并在该适当距离处的受话器本体上四周穿设有一个以上的入音孔,又该喇叭上两语音功率的输出端侧中,其相对音压高低强度值较低的那一输出端,是朝向该出音孔输出者;藉由上述的结构,除令佩戴者在使用时可聆听到外界的声响外,亦可有效防止高强度音压(Impulse Noise)冲击入人耳中而产生中耳受伤及导致传音性听力的损失(Conductive Hearing Loss)。

Description

无冲击噪音且可同步接收外界声响的耳塞式受话器
技术领域:
本发明是与耳塞式受话器结构有关,特别是指一种可同时听到外界警告声响又可避免高强度音压冲击的耳塞式受话器,使人们在佩带该耳塞式受话器时,除可得知周遭外界发生的声响外,亦可避免高强度音压的不断冲击所造成的听力损失。
背景技术:
如图1至图3所示,是传统的耳塞式受话器结构,其包括一受话器本体10、一喇叭20及一出音盖30;其中,该受话器本体10具有一中空容置室11及一开口端12,该喇叭20是置放於该受话器本体10之中空容置室11中,而该出音盖30则嵌置入该受话器本体10之开口端12上,且於该出音盖30朝向该喇叭20之盖面上设具有复数个出音孔31,而该喇叭20之高强度音压音源输出端21是朝向该出音盖30之出音孔31,使人们将该耳塞式受话器塞置入人耳A之耳珠A1及对耳珠A2间(如图1所示)後,该喇叭20所发出的音域得以经由该出音孔31传输入至人耳A中;
由上述得知,当人们在使用传统的耳塞式受话器聆听时,该喇叭20所发出的音乐或声响皆会经由该出音盖30的出音孔31而尽数进入至人耳中,以致外界的声响并无法穿透过该受话器本体10,而与该喇叭20所输出的音域一起进入至人耳中,故一旦使用传统的耳塞式受话器时,人耳所听到的声响均是该喇叭20发出的声音,以致人们仅知晓对於眼前的危险,但对发生於四周的警告声响却往往浑然不知,而此种情况对於一边聆听一边行车的驾驶者或行人皆是一件相当危险的事情;
再者,在1997年美国西南医学中心(UT Southwestern MedicalCenter)在对13-19岁间青少年的听力损失(Hearing Loss in Teens)所做的报告中指出:「在美国的国民中13-19岁间的青少年约百分之二十有听力障碍,且听力丧失的原因其大部份是曝露於噪音环境中,尤其是耳塞式受话器所发出的冲击性音乐。」;所以在使用传统的耳塞式受话器除应注意音量的控制外(音压在105dB时,一天的使用时间应不超过一小时为宜,若音压为95dB时一天则不得超过六小时),亦应注意耳机同时发出的冲击性噪音(Impulse Noise),因为此种极短时间的冲击噪音中皆含有极高的音压,易造成耳膜破裂或中耳听力的丧失,而此种中耳听力传音功能的障碍,即称为传音性的听力损失(Conductive Hearing Loss),所以,近年来在美国的医学报告中不断地指出,青少年因使用耳塞式受话器聆听热门音乐(如摇滚乐等),导致听力损失的人数百分比年年都在持续的增加中,故不当的使用耳机,不仅正在侵蚀美国青少年的听力健康,亦危及世界各国的青少年健康。
因此,传统之耳塞式受话器中所发出的声音均是含有高强度音压的音域,造成人们在佩戴时,该高强度的音压即会不断地冲击入该人耳A的外耳道B内,而使中耳产生疼痛等不适感,且长时间聆听亦会使中耳受伤及导致听力的损失。
本发明的主要目的在于提供一种无冲击噪音且可同步接收外界声响的耳塞式受话器,由於本发明在使用过程中,对於周遭所发出的警告声响均会与受话器中喇叭所发出的声音一并进入至人耳中,使人们在聆听音乐(Music)或语音(Voice)时,亦可听到外界的危险警告响声,而使人们可立即做出闪离危险的动作,完全革除传统的耳塞式受话器在聆听同时无法得知外界警告声响的缺失。
本发明的另一目的在于提供一种无冲击噪音且可同步接收外界声响的耳塞式受话器,由於本发明所输出的音域中并无含有任何冲击性的高强度音压,而使人们在佩戴该耳塞式受话器聆听音乐时,除可有效地防止高强度音压的冲击中耳伤害外,亦可避免中耳受伤及导致听力损失等发生。
发明内容:
一种无冲击噪音且可同步接收外界声响的耳塞式受话器,是於该受话器本体的内部空间中置放有一喇叭,而该受话器本体的前缘穿设至少有一出音孔,且该喇叭所置放的位置与该受话器本体前缘的位置两者间相距有一适当距离,并在该适当距离处的受话器本体四周上穿设有一个以上的入音孔,又该喇叭上两语音功率的输出端侧中,其相对音压高低强度值较低的那一输出端,是朝向该出音孔来配置。
一种无冲击噪音且可同步接收外界声响的耳塞式受话器,其是在该受话器本体的内部空间中置放有一喇叭,而於该受话器本体的前缘上穿设至少有一出音孔,该受话器本体的内部空间中固定该喇叭的内壁面上穿设有一个以上可连通本体内部喇叭前面和后面空间的连通孔,而该喇叭上两语音功率的输出端侧中,其相对音压高低强度值较低的那一输出端,是朝向该出音孔来配置,且该受话器本体背面的壁面上穿设至少有一入音孔。
本发明的优点是:形状、构造设计科学,使用时可聆听到外界的声响外,亦可有效防止高强度音压(Impulse Noise)冲击入人耳中而产生中耳受伤及导致传音性听力的损失(Conductive HearingLoss)。具有无冲击噪音及无高频率杂讯等多重功效,能最大限度地消除音域中的高频杂音,获高品质的音域,有效地保护人的听觉能力。

具体实施方式:
请参阅图4所示,本发明一种无冲击噪音且可同步接收外界声响的耳塞式受话器,是於受话器本体40的内部空间41中置放有一喇叭50,而该受话器本体40的前缘穿设至少有一出音孔42,且该喇叭50所置放的位置与该受话器本体40前缘的位置两者间相距有一适当距离δ,并在该适当距离δ处的受话器本体40四周上穿设有一个以上的入音孔43,又该喇叭50上两语音功率的输出端侧中,其相对音压高低强度值较低的那一输出端,是朝向该出音孔43来配置;
请参阅图5所示,当使用本发明时,首先是将该受话器本体40置放入人耳A中,使该受器本体40的前缘得以置放於该人耳A之耳珠A1及对耳珠A2中而不掉落,开始聆听音乐或语音後,人耳A外界的声响即会与经由该入音孔43进入至该受话器本体40内,而与该喇叭50所输出的音域一同进入至人耳A的外耳道B内,以致人耳A除可听到喇叭50所输出的音域外,亦可经由接听到的外界声响而得知周遭所发生的情事,以避免危险将至而不自知者;再者,由於该喇叭50之低强度音压音源输出端51是朝向该出音孔42,故外界声响一并进入至该人耳A之输出音域中并未含有高强度的音压,即便是人们长时间的聆听亦可避免受到高强度音压的冲击而产生疼痛等不适感,有效防止中耳受伤及导致听力损失的情事产生。
请参阅图6所示,是本发明的另一实施例,其是在该受话器本体60的内部空间中置放有一喇叭70,而於该受话器本体60的前缘上穿设至少有一出音孔61,并於该受话器本体60的内部空间中固定该喇叭70之内壁面上穿设有一个以上可连通本体内部喇叭前面和后面空间的连通孔62,而该喇叭70上两语音功率的输出端侧中,其相对音压高低强度值较低的那一输出端,是朝向该出音孔61来配置,另於该受话器本体60背面的壁面上设具至少有一入音孔63,使外界的声响得以由该入音孔63进入至该受话器本体60中,并再经该受话器本体60的穿孔62及出音孔61进入至该人耳A,而使人耳A在佩戴使用本发明时,可得知外界的声响,且同时由该受话器本体60的出音孔61所输出的低强度音压之音域,亦使人们聆听音乐时不会受到高强度音压的冲击,而产生疼痛等不适感或发生中耳受伤及导致听力损失的情事。
