In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
the embodiment of the self adaptation gluing, sealing device of measurement jig:
Refer to Fig. 1 to Fig. 4, below the most preferred embodiment of the self adaptation gluing, sealing device of measurement jig of the present utility model is set forth.
The self adaptation gluing, sealing device 10 of the measurement jig of the present embodiment, be suitable for earphone electro-acoustic test, wherein, earphone 200 comprises wears 201 and be located at the ear muff 202 wearing 201 both sides, and earphone electro-acoustic measurement jig 100 comprises fixed mount 10, is divided into two ear muffs placed for ear muff 202 at the two ends of fixed mount 10 and places housings 20 and be divided into two ear muffs and place two artitificial ears 30 on housing 20, preferably, this artitificial ear 30 is IEC-318 artitificial ear; One end that housing 20 placed by arbitrary ear muff is provided with can the storage tank 21 of accommodating ear muff 202, the other end of one end placing housing 20 relative to ear muff is provided with and is communicated with storage tank 21, with the inlet port 22 being placed in storage tank 21 for artitificial ear 30, and the self adaptation gluing, sealing device 40 of the present embodiment comprises contact 41 and adjustment part 42, below each parts of self adaptation gluing, sealing device 40 are described further:
Contact 41 is a flexible piece, it is in order to contact with ear muff 202, and wherein, this contact 41 is located in storage tank 21, it comprises at least one contact-making surface 411 in order to contact with ear muff 202, and contact 41 is provided with first inserting hole 412 that can intert for artitificial ear 30;
Adjustment part 42 is fit to seal with ear muff 202 in order to contact-making surface 411 shape of the appearance profile correspondence adjustment contact 41 according to ear muff 202, wherein, adjustment part 42 is located between the bottom wall of storage tank 21 and contact 41, and adjustment part 42 is provided with second inserting hole 421, second inserting hole 421 that can intert for artitificial ear 30 is communicated with inlet port 22, first inserting hole 412 respectively.
The self adaptation gluing, sealing device 40 of the present embodiment comprises contact 41 and adjustment part 42, thus, when earphone ear muff 202 is located at storage tank 21, the surface being located at storage tank 21 regardless of earphone ear muff 202 is plane or different in nature face, when it is located at storage tank 21, it first contacts with contact 41, then by adjustment part 42, fit to seal with earphone ear muff 202 with contact-making surface 411 shape of the appearance profile correspondence adjustment contact 41 according to earphone ear muff 202, the repeatability that can ensure test data when carrying out earphone 200 electroacoustical measurement is preferably made with this, avoid the problem occurring that earphone 200 is judged by accident by electruacousticfidelity instrument.
Refer to Fig. 4, preferably, the adjustment part 42 of the present embodiment is sponge.Wherein, sponge is a kind of porous material, it is not only soft, and there is good resilience, ductility, so, after contact 41 contacts with the ear muff 202 stretching into storage tank 21, the active force be subject to from ear muff 202 can be reached sponge by it, and sponge stressed after can be applied force compresses distortion, simultaneously, it also can drive contact 41 contraction distortion, to make the contact-making surface 411 of contact 41 be shrunk to the shape of mating with ear muff 202 outer contour shape, thus makes contact 41 and ear muff 202 seal laminating.
Particularly, the second end that sponge comprises first end and is oppositely arranged with first end, the first end of sponge is attached on the bottom wall of storage tank 21 by the first double faced adhesive tape 43, second end of sponge is attached on contact 41 by the second double faced adhesive tape 44, and adopt the first double faced adhesive tape 43, second double faced adhesive tape 44, not only draw materials conveniently, price material benefit, and it is easy to use, side by side, can also ensure that the first end of sponge leads to the adhesion with the adhesion of the bottom wall of storage tank 21, second end of sponge and contact 41 preferably.
Refer to Fig. 4, preferably, the contact 41 of the present embodiment is dermatine.Wherein, dermatine is on woven fabric base or nonwoven fabric base, formed by the foaming such as PVC and PU of various different formulations or overlay film processing and fabricating, can require be processed into according to varying strength and color, gloss, floral designs etc., have that designs and varieties are various, water resistance good, not care about one's appearance is neat, the high feature cheap relative to corium with price of utilance.And adopt dermatine as contact 41, the toughness of contact 41, intensity and useful life can be ensured.
Referring again to Fig. 4, in order to ensure contact 41 stress deformation preferably, this contact 41 is all positioned on adjustment part 42 in the projection of adjustment part 42, particularly, for the ease of processing sets up, this contact 41 and adjustment part 42 are rectangular configuration, so, understandably, the length and width size of contact 41 equals the length and width size of adjustment part 42.
In addition, in order to ensure that this artitificial ear 30 is located at ear muff smoothly and is placed in the storage tank 21 of housing 20, the center line of the first inserting hole 412, the center line of the second inserting hole 421 all overlap with the center line of inlet port 22.Side by side, the shape size of this first inserting hole 412, the shape size of the second inserting hole 421 are all identical with the shape size of inlet port 22, so that processing sets up.
Below in conjunction with each graphic, the operation principle of the self adaptation gluing, sealing device 10 of the measurement jig of the present embodiment is described further:
When needs carry out earphone electro-acoustic test to earphone 200, first, the storage tank 21 of housing 20 correspondence placed by two ear muffs two of earphone 200 ear muffs 202 being located at earphone electro-acoustic measurement jig 100, side by side, the surface being located at storage tank 21 regardless of earphone ear muff 202 is plane or different in nature face, when it is located at storage tank 21, it first contacts with contact 41, then by adjustment part 42, fit to seal with earphone ear muff 202 with contact-making surface 411 shape of the appearance profile correspondence adjustment contact 41 according to earphone ear muff 202, the repeatability that can ensure test data when carrying out earphone 200 electroacoustical measurement is preferably made with this, avoid the problem occurring that earphone 200 is judged by accident by electruacousticfidelity instrument.
measurement jig embodiment:
Refer to Fig. 1 to Fig. 4, below the most preferred embodiment of measurement jig of the present utility model is set forth.
The measurement jig 100 that the present embodiment provides, has above-mentioned self adaptation gluing, sealing device 40.
