Systems and methods for retaining a microphone using a microphone boot are disclosed. The microphone boot may include a sound channeling structure for receiving and delivering sound, and a microphone retaining block for retaining a microphone and passing the sound to the microphone. The sound channeling structure may be secured to a housing of an electronic device. The sound channeling structure may include a sound tube and a hooking component that may be insertable into a tunnel and a slot, respectively, of the microphone retaining block. The sound tube may deliver the sound into the tunnel for passing to the microphone. The hooking component may lock into the slot to secure the sound channeling structure to the microphone retaining block. Thus, the microphone boot may be tightly sealed to prevent leakage of the sound, and may fix the microphone within the electronic device even in the presence of external force.
