[0037] Reference Figures 1-6 A custom-designed Bluetooth performance testing device for hearing aids includes a housing 11. The device further includes a placement cavity 14 located within the housing 11, a positioning limiting block 12 detachably and fixedly connected to the front and rear side walls of the placement cavity 14, a placement slot 13 located on the positioning limiting block 12, a first positioning module 2 located on the lower side of the housing 11, and a second positioning module 3 located on the lower side of the first positioning module 2. The positioning limiting block 12 is fixedly connected to the placement cavity 14 via a snap-fit ​​or slider groove. The positioning limiting block 12 and the placement slot 13 can be adjusted according to the shape and size of the custom hearing aid housing. The first positioning module 2 and the second positioning module 3 are used to fix the antenna for the limiting test.

[0038] The placement cavity 14 is larger than the hearing aid shell.

[0039] The first positioning module 2 includes a positioning seat 21 disposed on the lower side of the placement shell 11, a positioning slot 22 disposed within the positioning seat 21, a support plate 23 fixedly connected to the side wall of the positioning slot 22, a positioning cavity 25 disposed within the positioning seat 21, and an antenna exposed slot 24 disposed within the left end wall of the positioning cavity 25. The positioning slot 22 penetrates the positioning seat 21 vertically and communicates with the positioning cavity 25. The positioning slot 22 is slidably connected to the placement shell 11. The antenna exposed slot 24 penetrates the positioning seat 21 horizontally and communicates with the positioning cavity 25. The support plate 23 can support the placement shell 11 and the hearing aid placed on the placement shell 11. The positioning cavity 25 is used to place and fix the upper side of the antenna, and the support plate 23 is used to place and fix the exposed part of the antenna.

[0040] The first positioning module 2 also includes a connecting block 26 having two parts that are respectively fixedly connected to the lower rear end face of the positioning seat 21.

[0041] The second positioning module 3 includes a base 31 that contacts and adheres tightly to the lower end face of the positioning seat 21, a base cavity 32 disposed inside the base 31, and an exposed slot 33 disposed on the lower end wall of the base cavity 32. The upper opening of the base cavity 32 communicates with the positioning cavity 25, and the base cavity 32 and the positioning cavity 25 have the same size. The base cavity 32 is used to place and fix the lower side of the antenna, and the exposed slot 33 penetrates the base 31 vertically.

[0042] The second positioning module 3 further includes two antenna positioning posts 34 that are detachably and fixedly connected to the lower right end face of the base 31. The antenna positioning posts 34 are threadedly connected to the base 31. The two antenna positioning posts 34 can fix the base 31 on the test equipment base plate to ensure that the antenna position is relatively fixed.

[0043] The second positioning module 3 further includes a connecting groove 35 with two grooves respectively located at the left and right rear ends of the base 31, wherein the connecting groove 35 has openings on the upper and rear sides, and the connecting groove 35 is slidably connected to the connecting block 26.

[0044] The front wall of the connecting groove 35 is provided with a slot communicating with the connecting groove 35, and the front side of the connecting block 26 is fixedly connected with a slot communicating with the connecting groove 35 and a slidably connected block.

[0045] Work or installation process:

[0046] In use, first place the antenna in the positioning cavity 25 and let the exposed part of the antenna pass through the antenna exposed groove 24. Then slide the positioning seat 21 and the antenna together from back to front against the base 31 so that the two connecting blocks 26 enter the two connecting grooves 35 respectively. The positioning seat 21 and the base 31 are fixed and limited by the front locking block of the connecting block 26 and the front locking groove of the connecting groove 35. At this time, the antenna is limited in the positioning cavity 25 and the base cavity 32 between the positioning seat 21 and the base 31.

[0047] Then, the antenna, the first positioning module 2 and the second positioning module 3 are fixed together on the base plate of the test equipment by the antenna positioning post 34 to ensure that the antenna position is relatively fixed. The placement shell 11 is placed in the positioning slot 22 and supported by the support plate 23.

[0048] Then, according to the size and style of the hearing aid shell to be tested, the corresponding positioning limit block 12 is installed and fixed on the side wall of the placement cavity 14. Then, the hearing aid is placed in the placement cavity 14, supported and locked by the positioning limit block 12, and positioned by the placement slot 13 to ensure that the relative position of the bottom reference surface of the hearing aid and the antenna is fixed. This ensures that hearing aids with different shells are tested under the same test conditions, and the final test results have practical reference significance.
