[0035] The following Figures 1 to 8 describes a button battery installation structure of a hearing aid earphone according to an embodiment of the present utility model.

[0036] A button battery installation structure of a hearing aid earphone includes a bottom shell 1 and an outer shell 2. At the connection of the bottom shell 1 and the outer shell 2, a function key 4 is provided through a provided support plate 3. The function key 4 includes a mode key 401, a volume key 402, and a power key 403, and they are sequentially penetrated through the support plate 3. Through the function key 4, the user is allowed to switch different working modes of the earphone. Inside the bottom shell 1, a bearing cavity 5 and a receiving cavity 7 are formed through a provided special-shaped partition plate 6. The special-shaped partition plate 6 divides the inner space of the bottom shell 1 into the bearing cavity 5 and the receiving cavity 7, which are respectively used for installing a circuit board 8 and a button battery 10. A circuit board 8 is fixedly installed inside the bearing cavity 5. An installation groove 9 is provided inside the receiving cavity 7, and a button battery 10 is placed in the installation groove 9. An adjusting component 16 extending inwardly through is correspondingly installed outside the installation groove 9. A limiting cover 13 is hinged at the top of the installation groove 9. The front ends of the bottom shell 1 and the outer shell 2 extend with a curved tube 17, and one end of the curved tube 17 is fixedly connected with a receiver 18. The curved tube 17 provides stable support and positioning for the receiver 18, ensuring effective conduction of sound and comfort of wearing. The main function of the receiver 18 is to amplify the sound signal so that the wearer can hear the sound more clearly.

[0037] Among them, the adjusting component 16 includes a fixing block 1601 which is arranged on the outer wall of the installation groove 9. A lead screw 1602 penetrates through the fixing block 1601. One end of the lead screw 1602 extends to the outside of the inner side of the installation groove 9 and is externally threaded with a threaded sleeve 1604. The other end of the lead screw 1602 is fixedly provided with a rotating handle 1603. A number of connecting rods 1605 are annularly arranged outside the threaded sleeve 1604. One ends of the number of connecting rods 1605 are fixedly connected with an arc-shaped block 1606, and the arc-shaped block 1606 is used to abut against the button battery 10 in the installation groove 9.

[0038] In this implementation scheme, during installation, first place the button battery 10 with the positive electrode facing up into the installation groove 9 to ensure that the positive electrode contact piece 11 and the negative electrode contact piece 12 are in close contact with the positive and negative electrodes of the battery respectively. Drive the lead screw 1602 to rotate by rotating the rotating handle 1603. Since the lead screw 1602 and the threaded sleeve 1604 are in threaded connection, rotating the lead screw 1602 will cause the threaded sleeve 1604 to move on the lead screw 1602. As the threaded sleeve 1604 moves, the connecting rods 1605 annularly arranged outside it will also move accordingly, thereby driving the arc-shaped block 1606 to move together. When the arc-shaped block 1606 moves to a suitable position, it will closely fit around the outside of the button battery 10, forming an enclosure and clamping of the battery, effectively preventing the battery from shaking in the installation groove 9 and improving the stability and reliability of power supply.

[0039] As Figures 5 - 6 shown, in this implementation scheme, a jack 1301 is opened at the edge of the limit cover 13. A sliding groove 14 is opened on the opposite side of the installation groove 9 with respect to the limit cover 13, and a plug rod 15 that cooperates with the jack 1301 is movably arranged in the sliding groove 14. By hinging the limit cover 13 on the top of the installation groove 9 and locking the limit cover 13 through the cooperation of the plug rod 15 and the jack 1301, the button battery 10 is completely fixed in the installation groove 9, ensuring close contact between the button battery 10 and the contact piece, thereby further ensuring the stability and reliability of power supply. When the button battery 10 needs to be replaced, only need to remove the plug rod 15 from the jack 1301, then adjust the arc-shaped block 1606 not to abut against the button battery 10, and then lift the limit cover 13 to replace it.

[0040] Furthermore, a positive electrode contact piece 11 and a negative electrode contact piece 12 are fixedly installed in the installation groove 9. The positive electrode contact piece 11 and the negative electrode contact piece 12 are matched with the button battery 10. The positive electrode contact piece 11 is fixed to the bottom surface of the limit cover 13. The contact piece is in direct contact with the positive and negative electrodes of the button battery 10 to achieve electrical connection, and transmit the electrical energy of the battery to the circuit board 8 for the earphone to use.

[0041] Further, a circuit board 8 is fixedly installed inside the bearing cavity 5. The circuit board 8 is electrically connected to the button battery 10 through a positive contact piece 11 and a negative contact piece 12. The function key 4 cooperates with a micro switch on the circuit board 8.

[0042] Specifically, the contact height between the positive contact piece 11 and the negative contact piece 12 is increased to 2-3 mm to improve the reliability of the contact between the contacts and the button battery 10.

[0043] As Figures 3 - 4 shown, in this embodiment, a plurality of limiting rods 101 are provided on the inner side of the bottom case 1 around the outer periphery of the accommodating cavity 7. Limiting holes 201 that cooperate with the plurality of limiting rods 101 are provided on the inner side of the outer case 2. The limiting rods 101 and the limiting holes 201 cooperate with each other to achieve the precise docking of the bottom case 1 and the outer case 2.
