FIG. 8 is a schematic view of the structure of FIG. 7 taken along the direction P5-P6. Fig. 9 is an enlarged schematic view of the structure at C in fig. 8. The first sound outlet channel 13 is located between the sound outlet hole 11 and the first cavity 121, and the first cavity 121 is communicated with the sound outlet hole 11 through the first sound outlet channel 13, for example, one end of the first sound outlet channel 13 is communicated with the first cavity 121, the other end of the first sound outlet channel 13 is communicated with the sound outlet hole 11, one end of the second sound outlet channel 14 is communicated with the second cavity 122, and the other end of the second sound outlet channel 14 is communicated with the first sound outlet channel 13, so that the first cavity 121 and the second cavity 122 are communicated with each other. Because the second cavity 122 is communicated with the first cavity 121 through the second sound outlet channel 14, the second sound wave signal generated by the receiver 20 in the second cavity 121 can be partially offset with the first sound wave signal generated in the first cavity 121 at the first sound outlet channel 13 and the sound outlet hole 11, so as to reduce the sound at the sound outlet hole 11, and further, the voice information of the user in the conversation process can be better prevented from being leaked.
