Abstract
The utility model discloses the design of a cellphone earphone using a sound collecting machine and a sound conducting pipe for reflecting sound to transfer sound. After the sound sent by the common electroacoustic earphone is transferred via the collection of the utility model, the sound can be transferred to human ears by means of sound reflection. Thus, a cellphone earphone with wires is far from human heads. Thereby, the possible electromagnetic radiation for the human heads because of the earphone with wires can be lightened.
Description
The utility model has designed a kind of handset earphone that utilizes sound reflecting to transmit sound.
Existing handset earphone has mostly adopted the electroacoustic earphone, directly is worn in the ear and emits sound.This makes mobile phone and to be worn between the electroacoustic earphone in the ear be to link to each other by charged lead." experiment that the Britain consumers' association announces a few days ago shows, using the suffered radiation of earphone conversation when phoning with mobile telephone is during without earphone three times to this.Not only use earphone not have protective effect, can aggravate radiation on the contrary human body.Show that according to this experiment when using mobile phone, earphone cord has played the effect of antenna virtually, it focuses on caller's brain position with radio wave, makes the people produce headache, loss of memory and problem such as can't sleep in short-term." (coming from central TV station on the 5th news hookup April in 2000)
The utility model has designed a kind of handset earphone that utilizes sound reflecting to transmit sound, makes the electroacoustic earphone of common live line away from human brain, thereby has alleviated because the earphone of live line and the electromagnetic radiation for human body head that may bring.
The present invention is described in further detail below with reference to accompanying drawing.
Accompanying drawing is vertical figure of the present invention.
With reference to accompanying drawing, (1) is sound collector, and it is a sleeve-like structure, than common The electroacoustic earphone is more bigger and have elasticity, just can entangle common electroacoustic earphone, Play effect fixing and that collect sound. (2) be voice conducting pipe, it is by elastic Flexible pipe is made, and the sound of being collected by sound collector can transmit along voice conducting pipe by sound reflecting.
(3) be player, it is shaped as horn-like, is convenient to be worn in the ear and easily sliding Fall. (4) be the player cover, it is made by one deck sponge, makes player be worn over ear In soft, comfortable, and play the effect that absorbs little clutter. Sound collector, acoustic Pipe, player can be with common plastics or form by once with rubber, like this can be greatly Reduce cost.
The sound that common electroacoustic earphone sends after the sound collector collection, is transferred to player by sound reflecting along voice conducting pipe, is passed to people's ear again by player.So just make the electroacoustic earphone of live line away from human brain, thereby alleviated because the earphone of live line and the electromagnetic radiation for human body head that may bring.
Claims (4)
1 one kinds of handset earphones that utilize sound reflecting to transmit sound is characterized in that the sound collector (1) of this handset earphone links to each other with voice conducting pipe (2), and voice conducting pipe (2) links to each other with player (3).
2 by the described handset earphone of claim 1, it is characterized in that described sound collector (1) can entangle common electroacoustic handset earphone.
3 by the described handset earphone of claim 1, it is characterized in that described voice conducting pipe (2) made by elastic flexible pipe.
