Abstract
The utility model discloses a sound transmission device, which comprises a sound introduction part and a sound delivery part. The utility model is characterized in that sound transmission passages of the sound introduction part and the sound delivery part are hollow sound transmission pipes which are connected with members, such as an earplug, etc. When the utility model is used, no current is transmitted, and effects, such as interference and poor sound quality, etc., which are generated by electromagnetic effect can not be generated. Besides, the utility model has the advantages of compact structure and convenient operation.
Description
The utility model relates to a kind of novel microphone device, specifically, relates to a kind of novel microphone device that prevents electromagnetic radiation.
Existing microphone device mostly adopts earphone and microphone, and the structure of earphone is that loudspeaker is placed earplug, and when wanting listening, earphone adopts the lead transmission of electric signals by loudspeaker electric signal to be become voice signal; Microphone then is that voice signal is changed into electric signal, is transferred to dispensing device by lead.Its common characteristic be since lead transmission be electric signal, be easy to generate galvanomagnetic effect, especially during wireless transmission, itself be equivalent to concentrate " antenna " of radiated electromagnetic wave, so use earphone or microphone to bring radiation to human body, long-time use can make the people that auditory dysesthesia is arranged, and can bring harmful effect to brain, and this is incompatible in the current society that pays attention to quality of life and the develop rapidly of communications industry.
Goal of the invention of the present utility model provides a kind of novel microphone device that can overcome above-mentioned shortcoming.
A kind of novel microphone device of the present utility model is achieved in that a kind of novel microphone device, comprise that sound imports part and sound submitting portion into, it is characterized in that: sound imports part into to be made up of sound input port, hollow voice conducting pipe, earplug, and hollow voice conducting pipe one end connects the sound input port, the other end connects earplug; The sound submitting portion is made up of pick-up head, hollow voice conducting pipe, voice output mouth, hollow voice conducting pipe one end connects pick-up head, and the other end connects a voice output mouth, and the hollow voice conducting pipe is two that main body is fixed together, one belongs to sound and imports part into, and another root belongs to the sound submitting portion.
Described sound imports hollow voice conducting pipe partly into to be made by nonmetallic materials.
Described sound imports part into and described sound submitting portion can a shared hollow voice conducting pipe.
Described sound imports the sound input port and the voice output mouth of described sound submitting portion of part into can be shared.
Described sound imports the earplug and the pick-up head of described sound submitting portion of part into can be shared.
Described hollow voice conducting pipe can be by fixed rod support.
Described fixed bar length behaviour ear is advisable to the distance of mouth.
Sound input port, sound conducting apparatus, earplug that described sound imports part into can be integrated no connectors or be connected or be connected by screw thread mouth by socket; The pick-up head of described sound submitting portion, hollow voice conducting pipe, voice output mouth can be to add the one-shot forming in man-hour not have connector or be connected or be connected by screw thread mouth by socket.
Described sound input port and sound delivery outlet can be provided with the joint that is fixed in other device when using.
The utility model has avoided electromagnetic wave to human body owing to adopt the direct conduct acoustic waves of hollow voice conducting pipe, especially the electromagnetic radiation that brain is produced.The utility model does not in use have the transmission of electric signal, can not be subjected to external electromagnetic interference, can improve the acoustic quality, and it is simple in structure, easy to use.
Specify structure of the present utility model and embodiment below in conjunction with embodiment.
Fig. 1 is the structural representation of microphone device of the present utility model.
Fig. 2 to Fig. 5 is the synoptic diagram of each embodiment of the present utility model.
Referring to a kind of novel microphone device shown in Figure 1, comprise that sound imports part 1 and sound submitting portion 2 into, it is characterized in that sound imports part into and is made up of sound input port 11, hollow voice conducting pipe 12, earplug 13, hollow voice conducting pipe 12 1 ends connect sound input port 11, the other end connects earplug 13; Sound submitting portion 2 is made up of pick-up head 21, hollow voice conducting pipe 12, voice output mouth 23, hollow voice conducting pipe 12 1 ends connect pick-up head 21, the other end connects a voice output mouth 23, two of being fixed together for main body of hollow voice conducting pipe 12, one belongs to sound and imports part 1 into, and another root belongs to sound submitting portion 2.
As shown in Figure 2, sound of the present utility model imports part 1 into and described sound submitting portion 2 can a shared hollow voice conducting pipe 12.As shown in Figure 3, sound of the present utility model import the voice output mouth 23 of the sound input port 11 of part 1 and described sound submitting portion 2 into can be shared.As shown in Figure 4, sound of the present utility model import the pick-up head 23 of the earplug 13 of part 1 and described sound submitting portion 2 into can be shared.As shown in Figure 5, hollow voice conducting pipe 12 of the present utility model can be supported by fixed bar 3.
