Description
Technical field
This utility model relates to audio frequency apparatus technology, particularly relates to the technology of a kind of built-in ear type noise reduction earflap.
Background technology
Earmuff is generally used for completely cutting off harshness, and traditional earmuff is the most all the case of simple in construction, every making an uproar effect also
Poor.Some earmuff also speaker in earmuff housing is built with cover, can play outer audio equipment by speaker in cover
Audio signal, but only earmuff housing undertakes every making an uproar, poor every effect of making an uproar, thus influence whether to listen to tonequality.
Utility model content
For defect present in above-mentioned prior art, technical problem to be solved in the utility model be to provide a kind of every
Make an uproar effective built-in ear type noise reduction earflap.
In order to solve above-mentioned technical problem, one provided by the utility model built-in ear type noise reduction earflap, including ear
Over body case, and be arranged in earmuff housing audio defeat circuit board, speaker in cover, in cover, the audio port of speaker is received
The audio output port of audio defeat circuit board；
It is characterized in that: also include inserting the earplug in earmuff housing；Described earplug is built-in with speaker in plug, in plug
The audio port of speaker receives an audio jack by tone frequency channel wire, equipped with audio socket on the outer wall of earmuff housing；Described sound
Frequently the audio output port of audio defeat circuit board received by socket.
Further, equipped with pick up on the outer wall of described earmuff housing, the audio port of described pick up receives audio frequency
The audio input port of Dolby circuit plate.
The built-in ear type noise reduction earflap that this utility model provides, can constitute Double-noise-reduction by earmuff housing and earplug
Protection, has every effective feature of making an uproar, and also can be used alone the monolayer noise reduction protective that earmuff housing is formed, Ke Yigen
According to using environment conversion noise reduction levels.
Accompanying drawing explanation
Fig. 1 is the structural representation of the built-in ear type noise reduction earflap of this utility model first embodiment；
Fig. 2 is the structural representation of the earplug in the built-in ear type noise reduction earflap of this utility model first embodiment.
Detailed description of the invention
Illustrate embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing, but the present embodiment need not
In limiting this utility model, every employing analog structure of the present utility model and similar change thereof, this utility model all should be listed in
Protection domain, the pause mark in this utility model all represents the relation of sum.
As Figure 1-Figure 2, the one built-in ear type noise reduction earflap that this utility model first embodiment is provided, including
Earmuff housing 1, and be arranged in earmuff housing 1 audio defeat circuit board 3, speaker 2, the audio frequency of speaker 2 in cover in cover
Port receives the audio output port of audio defeat circuit board 3；
It is characterized in that: also include the earplug 4 that can insert in earmuff housing 1；Described earplug 4 is built-in with speaker 8 in plug,
In plug, the audio port of speaker 8 receives an audio jack 5 by tone frequency channel wire, equipped with audio socket on the outer wall of earmuff housing 1
6；Described audio socket 6 receives the audio output port of audio defeat circuit board 3.
In this utility model first embodiment, equipped with pick up 7 on the outer wall of described earmuff housing 1, described pick up 7
Audio port receives the audio input port of audio defeat circuit board 3.
In this utility model first embodiment, described audio defeat circuit board is prior art, and audio defeat circuit board is used
In processing the audio signal that pick up exports, and in speaker, plug, speaker exports audio signal in cover.
The occupation mode of this utility model first embodiment has a following two:
Earmuff housing uses with earplug simultaneously: earplug is first filled in the auditory meatus of user, and by speaker in connection plug
Frequently the audio jack of port inserts the audio socket on earmuff housing exterior walls, then earmuff case cover is covered user ear；This
Under mode, the audio signal after audio defeat circuit board will process is delivered to fill in the broadcasting of interior speaker, and earmuff housing is as physics
The basis of isolation, laminating ear isolation harmful environmental noise, form the protection of ground floor noise, auditory meatus filled in by earplug, forms physics
The second layer protection of isolation, can obtain acoustic isolation effect at double；
It is used alone earmuff housing (not using earplug): earmuff case cover is covered user ear；Under this mode, audio frequency
Audio signal after Dolby circuit plate will process is delivered to speaker in cover and plays, earmuff housing as the basis of physical isolation,
Laminating ear isolation harmful environmental noise, forms the protection of monolayer noise；
Send audio defeat circuit board after microphone pickup external voice to, audio defeat circuit board implement noise reduction process
After be delivered to fill in interior speaker and/or cover in speaker play, audio defeat circuit board is at the audio frequency detecting that pick up is sent here
When signal is higher than upper audio limit threshold value set in advance, the audio signal sending pick up here is implemented the range of decrease and is processed or directly block
The output of this audio signal, thus realize the protection to user audition.
This utility model the second embodiment is with the difference of first embodiment: in the second embodiment, and audio socket is installed
Inwall at earmuff housing；Accordingly, in connection plug, the audio jack of speaker audio port also is located at earmuff shell in use
Internal.
This utility model first, second embodiment be all pick up external voice by pick up after send audio defeat to
Circuit board, in this utility model other embodiments, it is also possible to change pick up into Audio input jack, so can be by other
The audio frequency that audio output apparatus is exported is as source of sound.
