The invention provides a sound processing apparatus is capable of performing failure diagnosis while performing sound processing. A sound processing apparatus D includes a microphone 200, a band-pass filter 300, an audio signal processor 400, a Fourier transformer 500, and a signal level determiner 600. The microphone 200 is configured to simultaneously acquire an audible sound and an inaudible sound, and to convert the acquired audible and inaudible sounds into electric signals, and to output the electric signals. The band-pass filter 300 receives the electrical signals outputted from the microphone 200 and removes components of the electrical signals that are outside the audible range. The audio signal processor 400 apply predetermined signal processing to the electric signals that have passed through the band-pass filter 300. The Fourier transformer 500 obtains frequency components in an inaudible range on the basis of the electric signals outputted from the microphone 200. The signal level determiner 600 performs a first determination as to whether the frequency components in the inaudible range have a signal level being equal to or greater than a threshold value.

The invention provides a plug connector which, when abnormal heating occurs in a fitting portion with a counter connector, can sensitively cut off the current supply. The plug connector has: contacts 30; a body 50 which holds the contacts 30; a metal shell 60 which covers the body 50; and a printed circuit board 70 on which the contacts 30 are solder-connected. The body 50 has a fitting portion 52 with a counter connector. The board 70 has a thermal protection circuit 80. The thermal protection circuit 80 has a temperature switch IC 90 which detects a temperature, and an FET 100 which is disposed in a power supply wiring of the board 70. When the detected temperature of the temperature switch IC 90 exceeds a predetermined temperature, the power supply wiring is cut off by the FET 100. In the plug connector, the board 70 has a heat conduction pattern 110 which conducts heat of the metal shell 60 to the temperature switch IC.

The invention provides a connector having a high degree of design flexibility. A connector C1 includes a shield case 100, a body 200, and a terminal 300. The shield case 100 includes a first shell 100a and a second shell 100b. The first shell 100a includes a connecting portion 110a extending in Y-Y' direction and a cover 120a extending in the Y-Y' direction. The second shell 100b is a separate member from the first shell 100a. The second shell 100b and the cover 120a constitute a composite tube extending in the Z-Z' directions. The body 200 and the terminal 300 held by the body 200 are housed in the shield case 100. The terminal 300 includes a first portion 310 and a second portion 320. The first portion 310 extends in the Y-Y' directions and is disposed inside the connecting portion 110a. The second portion 320 extends in the Z-Z' directions and is disposed inside the composite tube. The impedances of the two portions of the terminal 300 may be matched by adjusting the distances between the respective portions of the terminal 300 and the walls of their adjacent shells.
