Description

Auxiliary recording device for earphone audio detection

Technical Field

The utility model belongs to the supplementary field of recording of audio frequency detection specifically discloses a supplementary device of recording of earphone audio frequency detection.

Background

The sound emitted by the earphone can only be clearly heard after being worn, and can only be worn by one person at a time. If the sound quality of the sound emitted by the earphone is to be checked, the sound quality of the sound emitted by the earphone is evaluated, and the user can only know after wearing the earphone, and can only wear the earphone and evaluate the pronunciation by one person at a time. It is not possible if a plurality of persons are to evaluate the sound emitted by the headset at the same time. If the headset purchaser needs to assess the sound quality of the headset but not beside it, no assessment can be made, resulting in a purchase being rendered impossible.

In the existing method, sound emitted by an earphone is recorded by electronic equipment such as a mobile phone and the like, so that a plurality of people listen to the sound and evaluate the sound, or the sound is transmitted to people who are not on the spot to evaluate the sound. However, such recording is interfered by external noise, and the sound volume emitted by the earphone is attenuated, such as noise generated by a defective earphone, which is difficult to describe and perceive for the remote buyer.

The device collects sound and shields external interference through a simulation ear, records the sound emitted by the earphone, restores the original sound of the earphone to the maximum extent, and can be simultaneously provided for a plurality of detection or assessment personnel to listen and evaluate so as to make decisions for purchasers or quality control of producers.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and the present invention is not limited to the specific embodiments disclosed below.

1-3, including microphone 7, microphone 7 fixes in the artificial ear that flexible material made, and artificial ear is used for fixed earphone, and microphone 7 connects the one end of signal line 2, and the other end connecting plug 3 of signal line 2, and artificial ear can conveniently fix the earphone to can effectively isolated noise.

The artificial ear includes collection sound cup 1 of horn mouth form, and the one end opening of collection sound cup 1 is greater than the other end, and the one end that collection sound cup 1 opening is big is fixed with flexible piece 6, and the middle part of flexible piece 6 is equipped with round hole 5, and the aperture of round hole 5 is less than the earphone diameter, and collection sound cup 1 designs into the horn mouth form can conveniently put into the earphone, and the earphone fills in collection sound cup 1 back from round hole 5 department, and flexible piece 6 can the separation noise to fix a position the earphone.

The inner wall of collection sound cup 1 is connected with annular piece 8 perpendicularly, is fixed with a plurality of shell fragments 9 on the annular piece 8, and the tip of shell fragment 9 is connected with perpendicularly and blocks piece 10, and collection sound cup 1 bottom is fixed with base 4, and microphone 7 is fixed in base 4, and the inner wall of base 4 is equipped with the puigging, and shell fragment 9 and block piece 10 and be used for fixing a position the earphone of filling in collection sound cup 1, prevent that the earphone from rocking and causing the noise.
