Abstract

An earphone-speaker includes an earphone housing (40) and a loudspeaker (50) mounted in a sound chamber (41) of the earphone housing, wherein a front end of the earphone housing has an earplug (42). A plurality of sound outlet meshes (43) are provided on the earplug and a plurality of sound collecting meshes (44) are provided around the earphone housing, especially at a surrounding wall defined between the loudspeaker and the earplug of the earphone housing. Accordingly, the sound from outside can pass through the earphone housing, combine with the sound emitted by the loudspeaker, and transmit to the human ear, so that while people are listening to the music, they are still capable of hearing the sound and realizing the events outside to keep away from danger.

Description

Title

Earphone-Speaker

Technical Field

The present mvention relates to an earphone, and more particularly to an earphone- speaker, wherem the sound outside can be heard by the ear while wearing the earphone so that any events outside are able to be realized at once without taking off the earphone

Background Art

It is conventionally known that the ordinary earphone, referring to Figs 1 to 3 of the drawings, compπses an earphone housmg 10. a loudspeaker 20, and a sound outlet cover 30, wherem the earphone housmg 10 compπses a sound chamber 11 and an open-end 12 The loudspeaker 20 is held m the sound chamber 11 of the earphone housmg 10 and the sound outlet cover 30 is affixed to the open-end 12 of earphone housmg 10 A plurality of meshes 31 is mounted on the surface of the sound outlet cover 30 facmg the loudspeaker 20 When the earphone is used, the sound outlet cover 30 is constructed as an earplug adapted for hanging between a tragus Al and an antitragus A2 of human ear A, as shown in Fig 1 The sound emitted by the loudspeaker 20 will transmit to human ear A

In view of above, it is realized that when people are using the ordinary earphones, the sound emitted by the loudspeaker 20 will all transmit through the meshes 31 of the sound outlet cover 30 to the human ear A The sound from outside cannot pass through the earphone housmg 10 and cannot combme the sound emitted by the loudspeaker 20 together and then transmit to the human ear A So, when people wear the ordinary earphone, they can only hear the sound from the loudspeaker 20 and will completely be blocked hearing and knowing from outside, that may cause danger to their lives especially while they are dπvmg or walking on the street Disclosure of Invention

The objective of the present mvention is to provide an earphone-speaker, wherem the earphone enables the sound from outside passmg through the earphone housmg, combining with the sound emitted by the loudspeaker, and then transmitting to the human ear While the present mvention is used to listen to music, people are still capable of heaπng the sound and realizmg the events outside to keep away from danger The present mvention will cover the disadvantage of the ordinary earphone which completely blocks heaπng from outside

Best Mode for Carrying Out the Invention

Referring to Fig 4 of the drawing, an earphone-speaker in accordance with the present invention compπses an earphone housing 40 and a loudspeaker 50 mounted m a sound chamber 41 of the earphone housmg 40, wherem a front end of the earphone housmg 40 has an earplug 42. wherem a plurality of sound outlet meshes 43 are provided on the earplug 42 There is a proper distance δ provided between the loudspeaker 50 and the earplug 42 A plurality of sound collecting meshes 44 are formed around the earphone housmg 40. especialh at the suπounding wall between the loudspeaker 50 and the earplug 42

Referring to Fig 5, while the present mvention is used, the earphone housmg 40 is adapted to be placed on the human ear A, and the earplug 42 is adapted for hangmg fitly between a tragus Al and an antitragus A2 of the human ear A At the mean time, the sound outside passes through the sound collecting meshes 44 to the earphone housmg 40 and combmes the sound emitted by the loudspeaker 50 together and then transmits to the human ear A So. people can listen to the music from the earphone and hear the sound outside at the same time With this function of the present mvention, people will realize any events outside to keep away from dangerous

Referring to Fig 6, the outer side of the earplug 61 of the earphone housing 60 is formed as a donut-shape 62 The earphone housmg 60 will be held firmly by the donut-shaped part 62 hanging between a tragus Al and an antitragus A2 of human ear A
