Description

Technical Field

[0001] This utility model relates to the field of bone conduction product testing technology, specifically a bone conduction product testing device. Background Technology

[0002] Bone conduction products have become increasingly popular in recent years, including bone conduction headphones and bone conduction hearing aids. However, reliable testing solutions for bone conduction products are in urgent need.

[0003] Various bone conduction testing instruments commonly found on the market all have various shortcomings. In particular, testing solutions for bone conduction hearing aids all suffer from sound leakage problems. As is well known, once sound leakage occurs during the testing of a bone conduction hearing aid, it will be picked up by the microphone, amplified, and cause even greater leakage, resulting in feedback, making testing impossible. Utility Model Content

[0004] The purpose of this invention is to provide a bone conduction product testing device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0007] The bottom of the contoured earpiece is provided with a contoured sensor bottom, and the contoured sensor bottom is arranged opposite to the bottom of the contoured earpiece.

[0008] Furthermore, the bottom of the contour sensor is wholly or partially consistent with the vibration transmission surface features of the bone conduction earpiece under test.

[0011] Furthermore, the sound transmission and sound leakage prevention structure adopts one or a combination of silicone, plastic, rubber, foam, foam adhesive and sponge.

[0012] Furthermore, the sound transmission and sound leakage prevention structure is embedded with one or more of the following: metal, plastic, glass fiber, and nylon.

[0014] Furthermore, the external features of the bottom of the penetrating contoured earpiece, except for the penetrating portion, are wholly or partially consistent with the surface features of the bone conduction earpiece's vibration transmission surface.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model achieves the transmission of vibration from the bone conduction earpiece to the bone conduction sensor protrusion of the bone conduction sensor device when testing bone conduction earpieces through the setting of sound transmission and anti-leakage structure, and blocks sound leakage between the bone conduction earpiece transmission surface and the bone conduction sensor protrusion, thus ensuring the stability of the test.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figures 1-3 In this embodiment of the present invention, a bone conduction product testing device includes a bone conduction sensor device 3, a sound transmission and leakage prevention structure 1 mounted on the bone conduction sensor device 3, and a bone conduction earpiece 2 used in conjunction with the sound transmission and leakage prevention structure 1; the sound transmission and leakage prevention structure 1 includes a contoured earpiece side portion 11 and a contoured earpiece bottom portion 12, the contoured earpiece side portion 11 surrounding the contoured earpiece bottom portion 12 to form a concave open cavity;

[0029] The bottom of the contoured earpiece bottom 12 is provided with a contoured sensor bottom 14, and the contoured sensor bottom 14 is arranged opposite to the contoured earpiece bottom 12.

[0030] The sound transmission and sound leakage prevention structure 1 enables the bone conduction sensor device 3 to transmit the vibration of the bone conduction earpiece 21 to the bone conduction sensor protrusion 31 of the bone conduction sensor device 3 when testing the bone conduction earpiece 2, and blocks the sound leakage between the bone conduction earpiece 21 and the bone conduction sensor protrusion 31.

[0031] The bottom 14 of the contour sensor is fully or partially consistent with the surface features of the vibration transmission surface of the bone conduction earpiece 2 to be tested.

[0032] Among them, the surface features of the corresponding parts of the four sides of the bone conduction earpiece 2 are completely or partially consistent with those of the contoured earpiece side 11.

[0033] The contoured earpiece side 11 and the bone conduction earpiece transmission surface 21 can be designed to have an interference fit (i.e., tight fit) to block the bone conduction earpiece transmission surface 21 from air, thereby improving the sound leakage prevention effect.

[0034] The bottom 14 of the contour sensor is wholly or partially identical to the surface features of the bone conduction sensor protrusion 31 of the bone conduction sensor device 3. This arrangement can block sound leakage caused by the bone conduction sensor protrusion 31.

[0035] Among them, the sound transmission and sound leakage prevention structure 1 adopts one or a combination of silicone, plastic, rubber, foam, foam adhesive and sponge.

[0036] In the sound transmission and sound leakage prevention structure 1, the material between the bottom 12 of the contoured earpiece and the bottom 14 of the contoured sensor must be soft, compressible, and thin. More preferably, it must have air-blocking characteristics so that it can block sound leakage while transmitting vibration.

[0037] The sound transmission and leakage prevention structure 1 is embedded with one or more of the following materials: metal, plastic, fiberglass, and nylon. Embedding methods include overmolding and post-installation. Overmolding includes processes such as silicone overmolding of metal, plastic, fiberglass, and nylon, and plastic injection molding overmolding of metal, fiberglass, and nylon. Post-installation methods involve pre-reserving mounting slots / holes / structures in the soft sound transmission and leakage prevention structure for subsequent assembly, which differs from injection molding.

[0038] The external strength of the sound transmission and sound leakage prevention structure 1 can be improved by embedding one or more of metal, plastic, glass fiber and nylon, which facilitates assembly and placement.

[0039] Example 2:

[0040] Please see Figure 3 and Figure 4 Based on Example 1, the bottom 12 of the contoured earpiece has one or more perforations to form a perforated bottom 13 of the contoured earpiece.

[0041] The external features of the bottom 13 of the penetrating contoured earpiece, except for the penetrating part, are wholly or partially consistent with the surface features of the bone conduction earpiece transmission surface 21.

[0042] By incorporating a through-hole design at the bottom 13 of the stylus earpiece, the bone conduction earpiece's transmission surface 21 directly abuts against the bone conduction sensor's protrusion 31. This effectively thins the bottom 12 of the stylus earpiece (the thinner the gap between the bottom 12 and the bottom 14 of the stylus sensor, the better; ideally, it should have an opening to allow the bone conduction earpiece's transmission surface 21 to directly abut against the bone conduction sensor's protrusion 31, minimizing the impact on the damping effect of the bone conduction earpiece's transmission surface 21 while blocking sound leakage, thereby improving sound transmission efficiency).

[0043] Typically, the protrusion 31 of the bone conduction sensor is made of silicone rubber, while the vibration transmission surface of the bone conduction earpiece is made of silicone or plastic. The protrusion 31 can also be flat. During testing, a force of 250g is applied to the bone conduction sensor protrusion 31 on the bone conduction earpiece 2. Under this external force, a contact area is formed between the vibration transmission surface 21 of the bone conduction earpiece and the bone conduction sensor protrusion 31. The optimal size and shape of the opening should be slightly larger than this contact area, and the area around the opening should be thin.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
