摘要： The present invention is a signal processing circuit 12 for an electrostatic electroacoustic transducer configured to correct signals input to a single driven electrostatic electroacoustic transducer 15 including a diaphragm 151 and a fixed electrode 152 disposed to face the diaphragm. The signal processing circuit includes a correction value determiner 122 configured to determine a correction value v1 of a level based on a level of the input signals s1 from the sound source, and a level corrector 124 configured to correct the level of the input signals based on the correction value. The level corrector is configured to correct the level of an input signal among the input signals based on the correction value. The input signal corresponds to a signal for displacing the diaphragm to a first direction side on which a fixed electrode is not disposed with respect to a predetermined position.

摘要： An earpiece whose inner cylinder is not crushed when the earpiece is inserted into an ear canal of a user is provided. An earpiece according to the present invention includes an inner cylinder 1 that includes one open end and the other open end and is attached to a sound conduit C of an earphone E, and an outer cylinder 2 connected to the one end of the inner cylinder and extending in an umbrella shape toward the other end of the inner cylinder so as to cover an outer surface 1b of the inner cylinder. The inner cylinder includes a fitting part 11 into which a tip of the sound conduit is fitted, and a sound guide part 12 configured to guide sound wave from the sound conduit to an ear canal. The sound guide part includes a constant diameter part 121 that has a constant inner diameter toward the one end side from the other end side and is disposed adjacent to the fitting part, and an expanded diameter part 122 that has an inner diameter continuously expanding toward one end side from the other end side and is disposed adjacent to the constant diameter part. The other end of the expanded diameter part is disposed closer to the other end side compared to a boundary B between an inner surface 2a of the outer cylinder and the outer surface of the inner cylinder in an axial direction orthogonal to a radial direction of the inner cylinder. The length between an inner surface 122a of the expanded diameter part and the outer surface of the inner cylinder in the radial direction of the expanded diameter part is the shortest at the boundary.

摘要： The present invention provides a signal processing device that allows a user, who adjusts a signal level to match a reference level, to adjust the signal level while checking a degree of difference between the signal level and the reference level.
A signal processing device according to the present invention comprises: an input part 20 to which an input signal is input; a storage 40 that stores therein one or more setting values of a parameter to be used for amplifying the input signal and a reference value of the setting value; an amplification part 30 that generates an output signal by amplifying a level of the input signal based on the setting value; an output part 70 that outputs the output signal; an adjustment part 50 that adjusts the setting value; and a display 60 that displays a display result determined based on the setting value adjusted by the adjustment part and the reference value. The display result displayed on the display 60 includes: a specific display result displayed when a relation between the setting value and the reference value is a specific relation; and a non-specific display result displayed when the relation between the setting value and the reference value is different from the specific relation.
