Abstract
The utility model provides a kind of In-Ear noise-measuring system, include the strut and ear-hang connected by shaft, one end of strut is connect with ear-hang, the other end of strut is equipped with In-Ear microphone, In-Ear microphone includes having chlamydate microsensor, microsensor connects transaudient conduit, and one end of transaudient conduit connects microsensor, and the other end of transaudient conduit is provided with Air Filter.Using In-Ear noise detection apparatus provided by the utility model, by accurately detecting the noise figure in ear, shield listens the wearing of device more reasonable, and noise reduction more preferably, and is worn securely, will not arbitrarily be fallen.
Description
Technical field
The utility model is related to a kind of occupational health instruments, and in particular to a kind of In-Ear noise-measuring system.
Background technology
The sound level meter microphone size that current market is sold can not be placed on measurement operating personnel in duct and put on shield
Listen the noise figure after earmuff.At present operating personnel worn in workplace shield listen device can only by measure field noise figure, then
It listens the suitable shield of device noise reduction parameters selection to listen device according to measurement result comparison shield, can not accomplish most suitable noise abatement, in this way
Operating personnel in workplace that can be larger to noise hazard, brings the healthy hidden danger that can not be estimated.
Utility model content
The utility model is intended to provide a kind of In-Ear noise detection apparatus, solves the prior art and is commented according to the noise at scene
Estimate it is not reasonable, wear shield listens the ineffective of device, influence the health of operating personnel.
The utility model provides a kind of In-Ear noise-measuring system, includes the strut and ear-hang connected by shaft,
One end of strut is connect with ear-hang, and the other end of strut is equipped with In-Ear microphone, and In-Ear microphone includes that tool is chlamydate
Microsensor, microsensor connect transaudient conduit, and one end of transaudient conduit connects microsensor, transaudient conduit it is another
End is provided with Air Filter.
Further, friction plate is set in the shaft between strut and ear-hang.
Further, microsensor connects amplifier.
It is protected using In-Ear noise detection apparatus provided by the utility model by accurately detecting the noise figure in ear
Listen the wearing of device more reasonable, noise reduction more preferably, and is worn securely, will not arbitrarily be fallen.
Description of the drawings
Attached drawing described herein is used to provide a further understanding of the present invention, and is constituted part of this application,
The exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the improper of the utility model
It limits.In the accompanying drawings：
Fig. 1 schematically illustrates the schematic diagram for the In-Ear noise-measuring system that the utility model embodiment provides；
Fig. 2 schematically illustrates the strut that the utility model embodiment provides and ear-hang attachment structure schematic diagram；
Fig. 3 schematically illustrates the schematic diagram for the In-Ear microphone that the utility model embodiment provides.
Specific implementation mode
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.
With reference to attached drawing, the utility model embodiment provides a kind of In-Ear noise-measuring system, including is connected by shaft
Strut 1 and ear-hang 2, one end of strut 1 connect with ear-hang 2, the other end of strut 1 is equipped with In-Ear microphone 3, In-Ear wheat
Gram wind 3 includes having chlamydate microsensor 4, and microsensor 4 connects transaudient conduit 5, and one end connection of transaudient conduit is micro-
The other end of type sensor, transaudient conduit 5 is provided with Air Filter, and dirt obstruction wears acoustic conducting pipe 5 during Air Filter can effectively prevent two
It influences to use.
Microsensor 4 connects amplifier 6,6 connection processing device of amplifier.
The In-Ear noise-measuring system utilize transaudient conduit 5, stretch into the ear of operating personnel, from transaudient conduit 5 to
Microsensor 4 transmits sound so that the noise figure measured is more accurate, can obtain the most true noise reduction of operating personnel
Value, better detection operation personnel wear the effect that shield listens device.
Preferably, friction plate 7 is set in the shaft between strut 1 and ear-hang 2, strut 1 and ear-hang 2 are connected by shaft
It is to make shaft reach a kind of autobalance state using the weight of 2 part of ear-hang so that the device can steadily hang over ear
Above nonvoluntary to fall, setting friction plate 7 is so that shaft has certain damping, realization autobalance.
From the above, it can be seen that the In-Ear noise detection apparatus provided using the utility model embodiment, is passed through
Noise figure in accurate detection ear, shield listen the wearing of device more reasonable, and noise reduction more preferably, and wears secured, Bu Huisui
Meaning is fallen.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
