Abstract (en)
[origin: EP1843627A1] A personal voice-transmitted device includes at least one voice box and at least one voice-transmitted tube. The voice box has a speaker arranged therein, and is divided to a first space and a second space by the speaker. The voice-transmitted tube connects to one side of the voice box and extends outwardly and has an outlet. The device can generate and retain a low-pitched tone by resonance of the first space, and the low-pitched tone can be transmitted to the outside by the voice-transmitted tube to form an excellent low-pitched tone. The drawbacks of the prior art such as poor tone because of using an earphone, a shutting stress and an uncomfortable feeling because of inserting an earphone, an unsafe feeling because of hanging an earphone and a sanitation problem because of contacting an earphone can be improved. The device can be used with no restriction on occasions and time.
