Abstract
The utility model discloses a hood formula audiometry device, including shell and ear muff, the ear muff is connected with sound -generating device, is equipped with the puigging between ear muff and the shell, and the outer fringe of ear muff and shell all is equipped with the sealing member. The utility model discloses a hood formula audiometry device adopts and to set up puigging and edge between them between shell and the ear muff and set up the sealing member, effective isolation the external noise, form the silence space in the ear that receives survey person, guarantee the normal clear of hearing test. This hood formula audiometry device wears when the audiometry and is receiving survey person's head can carry out the hearing test, and need not to use in the soundproof room, and conveniently carries, has more extensive application.
Description
Technical field
This utility model relates to hearing test device, particularly to a kind of hood type listening device.
Background technology
Hearing test needs to carry out in relatively quietly environment, typically uses soundproof room.At soundproof room
In directly wear audiometric earphone and carry out hearing test.But soundproof room generally uses cement structures or sheet material
Structure, installs sound insulation door and window.Due to the requirement to test environment, hearing test is only capable of fixing
Place is carried out.When some special population needs to detect audition, the most inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of hood type listening device, at least can solve the problem that above-mentioned asking
One of topic.
For achieving the above object, according to an aspect of the present utility model, it is provided that a kind of hood type is surveyed
Device for tone frequencies, including shell and earmuff, earmuff connects microphone device, be provided with between earmuff and shell every
The outer rim of sound-absorbing layer, earmuff and shell is equipped with sealing member.Thus, the setting of puigging and double-layer seal part
Being set effective and isolated external noise, the ear at testee forms quiet space, it is ensured that hearing test
It is normally carried out.This hood type listening device is without using in soundproof room, and is convenient for carrying, and has wide
General application.
In some embodiments, shell covers testee ear peripheral region, and shell and earmuff are two
Group.Consequently facilitating the ears of testee are tested.
In some embodiments, sealing member is air bag.Thus, air bag has relative to rubber seal
There is good sound insulaton effect.
In some embodiments, shell connects face shield.Therefore, it is being subject to when two assembly housings all cover
During survey person's head, the face shield of two shells closes up, and can improve the stability of two shells.
In some embodiments, earmuff includes double Shell.Thus improve soundproof effect further.
In some embodiments, also include mobile device and control device, controlling device and control mobile
Device, mobile device is connected with shell.Thus, control device can control mobile device start and stop and
The direction of motion so that shell and earmuff move to testee, convenient operation.
In some embodiments, controlling device connection has pressure transducer, the position of pressure transducer
Corresponding with sealing member.Thus, sealing member overlays on testee head with certain pressure, with ensure every
The effectiveness of sound, pressure transducer can detect sealing member and act on the pressure of testee head.Work as pressure
When power is less than setting value, control device control mobile device moves increase sealing member and acts on testee head
The pressure in portion.
In some embodiments, microphone device is conductance microphone device and/or bone conduction microphone device.
The beneficial effects of the utility model are: hood type listening device of the present utility model use shell with
Puigging is set between earmuff and both edges arranges sealing member, be effectively isolated external noise,
Ear at testee forms quiet space, it is ensured that being normally carried out of hearing test.The audiometry of this hood type
Device is worn on testee head when audiometry can carry out hearing test, and without making in soundproof room
With, and be convenient for carrying, have and be more widely applied.
Accompanying drawing explanation
Fig. 1 is the structural representation of the hood type listening device of this utility model embodiment 1；
Fig. 2 is the structural representation of the hood type listening device of this utility model embodiment 2；
Fig. 3 is the structural representation of the hood type listening device of this utility model embodiment 3.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Embodiment 1
As it is shown in figure 1, the hood type listening device of present embodiment includes shell 1 and earmuff 2.Earmuff
Puigging 4 it is provided with between 2 and shell 1.Puigging 4 has multilamellar, is filled with deadener.Earmuff
2 and the outer rim of shell 1 be all installed with sealing member 5.Sealing member 5 is air bag, close relative to rubber
Envelope or foam seal have more preferable soundproof effect.Shell 1 covers testee ear peripheral region.When being subject to
When survey person wears this hood type listening device, the head of sealing member 5 and testee is close to, and is effectively isolated
External noise, forms quiet space around the ear of testee.
Shell 1 and earmuff 2 are two groups, during hearing test, are worn on the left and right sides of testee respectively,
So that the ears of testee are carried out Hearing esamination.
Earmuff 2 connects microphone device 3.Microphone device 3 is connected with hearing test system, hearing test
System controls microphone device 3 and sends different sound, to carry out hearing test.Microphone device 3 is gas
Lead microphone device and/or bone conduction microphone device.
Earmuff 2 includes double Shell.Vacuum-pumping between double Shell, improves soundproof effect further.
Embodiment 2
As in figure 2 it is shown, the hood type listening device of present embodiment is substantially the same manner as Example 1, no
It is with part, also includes mobile device 7 and control device.Control device and control mobile device 7, move
Dynamic device 7 is connected with shell 1.
Mobile device 7 includes motor 71, screw mandrel 72, slide plate 73 and slide rail 74.Motor 71
It is connected by shaft coupling transmission with screw mandrel 72.Slide plate 73 and slide rail 74 are slidably matched.Slide plate 73 is pacified
It is contained on screw mandrel 72.Shell 1 is connected by support is fixing with slide plate 73.Therefore, motor 71 energy
Enough drive slide plate 73 to move, and then drive shell 1 to move.
Motor 71 is connected with controlling device, controls device and is also associated with pressure transducer.Pressure sensing
The position of device is corresponding with sealing member 5, when sealing member 5 covers at testee head, and pressure sensing
Device can detect the sealing member 5 pressure to testee head.Control device control motor start and stop and
Rotation direction.
Control device control motor 71 to open, drive shell 1 to move towards testee, when pressure passes
Sensor detects when sealing member 5 reaches setting value to the pressure of testee head, controls device and controls electricity
Motivation 71 shuts down.Now sealing member 5 covers at testee head, and forming quiet space can open
Beginning hearing test.Wherein, motor 71 can be servomotor.
