Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figures 2-4As shown, this utility model embodiment provides an air-conducting headphone speaker, including a bracket 1, a diaphragm 2, a voice coil 3, a washer 4, a magnet 5, and a U-cup 6. Specifically, the bracket includes a bottom shell 101 and an upper shell 102 disposed on the upper surface of the bottom shell and communicating with the interior of the bottom shell. The junction of the upper shell and the upper surface of the bottom shell is located inside the upper surface of the bottom shell. The diaphragm is disposed at the opening of the bottom shell 101, and the closed end of the U-cup 6 is located inside the upper shell 102 while the open end is located inside the lower shell. The magnet 5 is fixed to the inner surface of the closed end of the U-cup, and the washer 4 is disposed on the magnet. One end of the voice coil 3 is connected to the diaphragm, and the other end extends into the open end of the U-cup. The speaker of this utility model adopts an open structure, and Bluetooth headphones using this speaker do not need to be inserted into the ear.

[0021] like Figures 1-3 As shown, the bottom shell 101 and the upper shell 102 of this embodiment are both close to the shape of a racetrack, that is, they are formed by a section of arc at each end of the square shape; correspondingly, the diaphragm 2, voice coil 3, washer 4, magnet 5 and U cup 6 are all racetrack shaped.

[0022] like Figures 1-2 As shown, the outer surface of the upper shell 102 and the upper surface of the bottom shell 101 form a stepped surface 1a; an arc-shaped solder pad 7 is also provided on the plane of the stepped surface.

[0023] Specifically, if Figure 3 As shown, the arc-shaped pad 7 includes an arc-shaped base plate 701, four welding plates 702 disposed on the upper surface of the arc-shaped base plate, a gap groove 703 between two adjacent welding plates, and a longitudinal notch 704 located in the side wall of the arc-shaped base plate between two welding plates located in the middle; the arc-shaped base plate and the four welding plates are integrally formed.

[0024] To ensure stable installation of the arc-shaped pad 7, such as Figure 3 As shown, two transverse blocking strips 103 are provided on the plane of the stepped surface 1a. The supporting plane between the two transverse blocking strips is arc-shaped. The arc-shaped solder pad 7 is fixed on the supporting plane, and the two ends of the arc-shaped solder pad abut against the two transverse blocking strips respectively. The transverse blocking strips 103 here are integrally formed with the bottom shell 101, that is, the two are made together by an integral molding process, such as common plastic parts are integrally formed by injection molding.

[0025] To ensure better alignment between the arc-shaped pad 7 and the supporting plane, the shape of the arc-shaped pad 7 is consistent with the supporting plane. A longitudinal groove 101a is provided in the side wall of the bottom shell 101, and a longitudinal notch 704 is located above the longitudinal groove and aligned with it. This allows the leads (power lines) inside the bracket 1 to be led out from the longitudinal notch 704 and the longitudinal groove 101a, and then glue is applied inside the groove to cover and protect them, preventing the leads from being exposed and broken.

[0026] like Figure 3 As shown, the stepped surface 1a is also provided with two strip-shaped perforations 104 for communicating the interior of the bottom shell 101 with the outside; the two strip-shaped perforations are located on both sides of the upper shell 102.

[0027] In order to install the U-cup 6, a radial boss 101b is provided at the lower end of the inner wall of the bottom shell 101, and the open end of the U-cup is placed on the radial boss; the closed end of the U-cup is flush with the open end of the upper shell 102, so that the U-cup can be completely installed in the bracket 1, the whole speaker has a neat appearance, occupies little space, and is easy to install.

[0028] This utility model also provides a Bluetooth headset, which includes the above-mentioned air conduction headphone speaker.

[0029] In the above description, it should be noted that the terms "installation", "connection", "connection" and other related terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; "set at" should be understood as "installed at" or "set at", including installation methods such as fixed installation and movable installation.
