PROBLEM TO BE SOLVED: To provide an information processor for processing an acoustic signal of an attached speaker in an electronic apparatus having a removable speaker, and to provide a method for selecting a module. SOLUTION: When a speaker A171 is connected with a speaker interface 34, an EC/KBC 27 detects high level, and an EQ circuit A31 is connected electrically by turning a switch 301 on through a switch signal line 52. When a speaker B172 is connected with the speaker interface 34, an ID signal line 50 drops to the ground and has a low level. The EC/KBC 27 detects low level, and an EQ circuit B32 is connected electrically by turning a switch 302 on through a switch signal line 53. COPYRIGHT: (C)2007,JPO&INPIT
