The outer protrusion 1132 is inclined from the middle portion toward the circumferential side in a direction away from the horn 111, and guides the sound emitted from the horn 111 to be transmitted to the sound outlet 1131 along the inclined surface of the outer protrusion 11331. Further, the middle portion of the external protrusion 11331 extends into the opening 1132, so as to shorten the distance between the middle portion of the external protrusion 11331 and the sound emitting portion 1113 of the speaker 111, so that the sound emitted by the speaker 111 is rapidly transmitted to the surface of the middle portion of the external protrusion 11331 and then transmitted to the sound emitting hole 1131 along the inclined surface of the external protrusion 11331, and the sound gathering effect is achieved to a certain extent, that is, the sound emitted by the speaker 111 is rapidly gathered and transmitted to the sound emitting hole 1131, and the sound emitting effect is good.

Further, the outer circumferential side of the outer protrusion 11331 extends in the horizontal direction to form a joining portion 11332 for transmitting the sound emitted from the horn 111 in the circumferential direction of the cover 1133. When the sound emitted from the speaker 111 is transmitted to the vicinity of the sound outlet hole 1131 along the inclined surface of the external protrusion 11331, if the sound is transmitted along the inclined surface of the external protrusion 11331, most of the sound is transmitted along the longitudinal direction of the end cap body 110, and the transmission direction of the sound is changed after the sound contacts a blocking object, so that the sound effect is greatly reduced when the sound is transmitted to the user. By providing the engaging portion 11332, the engaging portion 11332 extends in the horizontal direction, and the sound transmitted along the outer protrusion 11331 changes the transmission direction when being transmitted to the engaging portion 11332, and the sound is transmitted to the sound outlet 1131 in the horizontal direction, so that the sound transmitted from the sound outlet 1131 can be transmitted to the peripheral direction of the cover plate 1133 more, thereby ensuring the sound effect transmitted to the user.

Further, a sound emitting unit 11333 is provided on the outer peripheral side of the joining unit 11332; the inner surface of the amplification part 11333 is inclined outward toward the direction away from the opening 1132, so that the sound passing through the cover plate 1133 can be transmitted not only to the circumferential direction of the cover plate 1133, but also to the circumferential direction of the cover plate 1133 away from the surface of the end cover body 110 to some extent, and the sound is diffused to some extent, so as to avoid the occurrence of noise.

Further, the outer surface of the cover plate 1133 is recessed to form a recess, so that the streamline structure of the inner surface of the cover plate 1133 is the same as or similar to the streamline structure of the outer surface, and the cover plate 1133 has a uniform thickness, and has a uniform sound insulation effect on the sound transmitted to the horn 111 on the inner surface of the cover plate 1133.
