The microphone module includes a mounting seat having two oppositely spaced-apart upright suspension surfaces extending transversely from the top wall. A buffer member includes a main body disposed between and spaced apart from the suspension surfaces, and two suspension bumps protruding from the main body toward and abutting respectively and tightly against the suspension surfaces. The main body has an inner portion defining an accommodating space. A microphone body is disposed in the accommodating space. ## Claims ### Claim 1 A microphone module comprising: a mounting seat including two oppositely spaced-apart upright suspension surfaces; a buffer member including a main body disposed between and spaced apart from said suspension surfaces, and two suspension bumps protruding from said main body toward and abutting respectively and tightly against said suspension surfaces, said main body having an inner portion defining an accommodating space; and a microphone body disposed in said accommodating space. ### Claim 2 (depends on 1) The microphone module as claimed in claim 1, wherein said mounting seat further includes a first abutment face connected between said suspension surfaces and spaced apart from said main body, said buffer member further including at least one first bump protruding from said main body toward and abutting against said first abutment face. ### Claim 3 (depends on 1) The microphone module as claimed in claim 1, wherein said mounting seat further includes two spaced-apart ribs disposed on one side of and spaced apart from said main body said buffer member further including an elongated bump protruding from said main body toward and abutting against said ribs. ### Claim 4 (depends on 1) The microphone module as claimed in claim 1, wherein said buffer member further includes a tubular portion extending from said main body away from said accommodating space, said tubular portion communicating said accommodating space with an external environment and being transverse with an arrangement direction of said suspension bumps. ### Claim 5 (depends on 1) The microphone module as claimed in claim 1, wherein said main body has an upright flat area on one side thereof, and an inclined area extending oppositely, downwardly, and inclinedly from a bottom end of said flat area. ### Claim 6 (depends on 1) The microphone module as claimed in claim 1, wherein said buffer member is made of rubber with Shore A hardness greater than or equal to 30 degrees and less than or equal to 40 degrees. ### Claim 7 (depends on 1) The microphone module as claimed in claim 1, wherein a ratio of a contact area of said buffer member with said mounting seat and a total area of an outer surface of said buffer member is greater than or equal to 0.05 but smaller than 0.2. ### Claim 8 (depends on 2) The microphone module as claimed in claim 2, wherein said mounting seat further includes a second abutment face connected transversely to said suspension surfaces and said first abutment face and spaced apart from said main body, said buffer member further including a second bump protruding from said main body toward and abutting against said second abutment face. ### Claim 9 (depends on 2) The microphone module as claimed in claim 2, wherein said buffer member includes a plurality of said first bumps protruding from said main body toward said first abutment face, said main body having a wire passing hole disposed between said first bumps and communicating said accommodating space with an external environment. ### Claim 10 (depends on 4) The microphone module as claimed in claim 4, wherein said mounting seat further includes a positioning plate disposed between said suspension surfaces opposite to said first abutment face and abutting against one side of said tubular portion, said positioning plate having a positioning groove receiving a portion of said tubular portion. ### Claim 11 (depends on 10) The microphone module as claimed in claim 10, wherein said positioning plate further has two abutment portions abutting against said main body, said positioning groove being formed between said abutment portions. ### Claim 12 An electronic device comprising: a housing including top and bottom walls; and a microphone module mounted in said housing and including a mounting seat including two oppositely spaced-apart upright suspension surfaces extending transversely from said top wall, a buffer member including a main body disposed between and spaced apart from said suspension surfaces, and two suspension bumps protruding from said main body toward and abutting respectively and tightly against said suspension surfaces, said main body having an inner portion defining an accommodating space, and a microphone body disposed in said accommodating space. ### Claim 13 (depends on 12) The electronic device as claimed in claim 12, wherein said mounting seat further includes a first abutment face connected between said suspension surfaces and spaced apart from said main body, said buffer member further including at least one first bump protruding from said main body toward and abutting against said first abutment face. ### Claim 14 (depends on 12) The electronic device as claimed in claim 12, wherein said mounting seat further includes two spaced-apart ribs protruding from said bottom wall and spaced apart from said main body, said buffer member further including an elongated bump protruding from said main body toward and abutting against said ribs. ### Claim 15 (depends on 12) The electronic device as claimed in claim 12, wherein said buffer member further includes a tubular portion extending from said main body away from said accommodating space, said tubular portion communicating said accommodating space with an external environment and being transverse with an arrangement direction of said suspension bumps. ### Claim 16 (depends on 12) The electronic device as claimed in claim 12, wherein said main body has an upright flat area on one side thereof, and an inclined area extending oppositely, downwardly, and inclinedly from a bottom end of said flat area. ### Claim 17 (depends on 12) The electronic device as claimed in claim 12, wherein said buffer member is made of rubber with Shore A hardness greater than or equal to 30 degrees and less than or equal to 40 degrees. ### Claim 18 (depends on 12) The electronic device as claimed in claim 12, wherein a ratio of a contact area of said buffer member with said mounting seat and a total area of an outer surface of said buffer member is greater than or equal to 0.05 but smaller than 0.2. ### Claim 19 (depends on 12) The electronic device as claimed in claim 12, wherein said housing and said mounting seat are integrally formed as one piece. ### Claim 20 (depends on 13) The electronic device as claimed in claim 13, wherein said mounting seat further includes a second abutment face connected transversely to said suspension surfaces and said first abutment face and spaced apart from said main body, said buffer member further including a second bump protruding from said main body toward and abutting against said second abutment face. ### Claim 21 (depends on 13) The electronic device as claimed in claim 13, wherein said buffer member includes a plurality of said first bumps protruding from said main body toward said first abutment face, said main body having a wire passing hole disposed between said first bumps and communicating said accommodating space with an external environment. ### Claim 22 (depends on 15) The electronic device as claimed in claim 15, wherein said mounting seat further includes a positioning plate disposed between said suspension surfaces opposite to said first abutment face and abutting against one side of said tubular portion, said positioning plate having a positioning groove receiving a portion of said tubular portion. ### Claim 23 (depends on 22) The electronic device as claimed in claim 22, wherein said positioning plate further has two abutment portions abutting against said main body said positioning groove being formed between said abutment portions.
