The positioning assembly structure 13 includes at least one positioning notch 131 disposed on the circumferential outer wall of the support body 11, and at least one positioning protrusion 132 correspondingly inserted into the positioning notch 131. The positioning protrusion 132 of the front cover 12 is correspondingly inserted into the positioning notch 131 of the bracket body 11 to form a circumferential limit, so that the housing 10 is integrally formed and a cavity is formed inside the housing 10, and the vibration assembly 20 is disposed in the cavity of the housing 10. The whole structure is compact, and the installation is convenient and fast.
The vibration component 20 comprises an annular seat 21 arranged in the shell 10, an anti-vibration elastic sheet 22 arranged in the annular seat 21, a vibration structure 23 arranged in the middle of the anti-vibration elastic sheet 22, a vibration diaphragm 24 arranged on the inner wall of one side of the annular seat 21 far away from the anti-vibration elastic sheet 22 and connected with one end of the vibration structure 23 far away from the anti-vibration elastic sheet 22, and a voice coil 24 embedded on the outer wall of the shell 10. The circumferential outer wall of the annular seat 21 is provided with at least one annular protrusion 211 embedded in the positioning notch 131, the annular protrusion 211 on the annular seat 21 is embedded in the positioning notch 131, and the annular seat 21 is located between the bracket body 11 and the front cover 12, so that the annular seat 21 can be stably fixed in the cavity of the housing 10. The middle of one end of the bracket body 11 far away from the front cover 12 is provided with at least two air inlets 111 arranged at intervals. The air inlet holes 111 are arranged to ensure that the two sides of the sound film are different, so that the sound film is prevented from being broken due to different air pressures on the two sides when the sound film vibrates.
The voice coil 24 is embedded on the outer wall of the end of the support body 11 far away from the front cover 12, and an annular sleeve 14 for sealing the voice coil 24 is arranged on the outer wall of the support body 11. The annular sleeve 14 is positioned on the outer side of the air inlet hole 111, so that the air inlet hole 111 cannot be blocked when the telephone receiver is installed, and an air inlet mode is ensured. The voice coil 24 is embedded in the support body 11 and sealed by the annular sleeve 14, so that the voice coil 24 is prevented from being interfered by the outside. Meanwhile, a connection terminal 251 which penetrates through the housing 10 and is connected with the voice coil 24 is arranged on the outer wall of the housing 10, the connection terminal 251 transmits an electric signal to the voice coil 24, the voice coil 24 generates magnetism by flowing current, the vibration structure 23 is attracted to vibrate in the circumferential direction, the anti-vibration elastic sheet 22 gives corresponding vibration elasticity to the vibration structure 23, vibration transmitted in the radial direction of the vibration structure 23 is absorbed, and the vibration is prevented from being transmitted to the housing 10.
The vibrating structure 23 includes a magnetic steel 231 disposed in the mounting cavity 31, and a magnetic conductor 232 disposed at an end of the magnetic steel 231 far away from the mounting cavity 31.
