A sound pick-up device comprising: a housing having a sound hole; a main microphone which is disposed in an inside of the housing, receives sound pressure from an outside of the housing through the sound hole, and generates a first sound signal; a reference microphone which is disposed in the inside of the housing and in a proximity of the main microphone and generates a second sound signal; a first shield which blocks between the inside of the housing and an inside of the main microphone, thereby not allowing a free transmission of sound between the inside of the housing and the inside of the main microphone, wherein at least a part of the first shield is an outer case of the main microphone; a third shield which blocks between the inside of the housing and the inside of the reference microphone, thereby not allowing a free transmission of sound between the inside of the housing and the inside of the reference microphone, wherein at least a part of the third shield is an outer case of the reference microphone; a second rubber member having a cylindrical shape with an end face and covering an outer circumference of the reference microphone characterized by a first rubber member having a cylindrical shape with an end face and covering an outer circumference of the main microphone, wherein, the main microphone and the reference microphone are adapted to be pressure-inserted into recessed portions of the housing by elastically deforming the first and second rubber members; and a second shield which blocks sound pressure from being transmitted between the outside of the housing and an inside of the reference microphone, wherein at least a part of the second shield is the housing. a housing having a sound hole; a main microphone which is disposed in an inside of the housing, receives sound pressure from an outside of the housing through the sound hole, and generates a first sound signal; a reference microphone which is disposed in the inside of the housing and in a proximity of the main microphone and generates a second sound signal; a first shield which blocks between the inside of the housing and an inside of the main microphone, thereby not allowing a free transmission of sound between the inside of the housing and the inside of the main microphone, wherein at least a part of the first shield is an outer case of the main microphone; a third shield which blocks between the inside of the housing and the inside of the reference microphone, thereby not allowing a free transmission of sound between the inside of the housing and the inside of the reference microphone, wherein at least a part of the third shield is an outer case of the reference microphone; a second rubber member having a cylindrical shape with an end face and covering an outer circumference of the reference microphone characterized by a first rubber member having a cylindrical shape with an end face and covering an outer circumference of the main microphone, wherein, the main microphone and the reference microphone are adapted to be pressure-inserted into recessed portions of the housing by elastically deforming the first and second rubber members; and a second shield which blocks sound pressure from being transmitted between the outside of the housing and an inside of the reference microphone, wherein at least a part of the second shield is the housing.
