“With regard to the in-vehicle conversation assist apparatus disclosed in JP 2002-51392, there may be a situation in which the sound output from electric loudspeakers is difficult to hear.”

As a supplement to the background information on this patent application, NewsRx correspondents also obtained the inventors’ summary information for this patent application: “In view of the above, an object is to provide a technique that can restrict occurrence of the situations in which the sound output from electric loudspeakers is difficult to hear.

“In one aspect, a conversation assist apparatus for a vehicle that includes a plurality of microphones and a plurality of electric loudspeakers, each microphone of the plurality of microphones and each electric loudspeaker of the plurality of loudspeakers being arranged so as to correspond to a seat of four seats arranged in a rectangular manner in a passenger compartment of the vehicle may include: a signal processor configured to generate an audio signal by adding a delay to an output signal of a microphone of the plurality of microphones; a supplier configured to supply the generated audio signal to an electric loudspeaker of the plurality of electric loudspeakers that corresponds to a diagonal seat, from among the four seats, that is located at a diagonal position of a seat corresponding to the microphone; and a controller configured to control an amount of the delay based on a state of the vehicle.

“In another aspect, a conversation assist apparatus for a vehicle that includes a plurality of microphones and a plurality of electric loudspeakers, each microphone of the plurality of microphones and each electric loudspeaker of the plurality of loudspeakers being arranged so as to correspond to a seat of four seats arranged in a rectangular manner in a passenger compartment of the vehicle may include a signal processor configured to generate an audio signal based on an output signal of a microphone of the plurality of microphones; and a supplier configured to switch, upon reception of a howling (feedback) noise occurrence signal indicative of occurrence of a howling noise, a destination of the generated audio signal from an electric loudspeaker of the plurality of loudspeakers that is a current destination of the generated audio signal to another electric loudspeaker of the plurality of electric loudspeakers that is different from the electric loudspeaker that is the current destination of the generated audio signal.

“In another aspect, a conversation assist apparatus for a vehicle that includes a plurality of microphones and a plurality of electric loudspeakers, each microphone of the plurality of microphones and each electric loudspeaker of the plurality of loudspeakers being arranged so as to correspond to a seat of four seats arranged in a rectangular manner in a passenger compartment of the vehicle may include: a signal processor configured to generate respective audio signals based on respective output signals of respective microphones of the plurality of microphones; and a supplier configured to supply each audio signal of the generated respective audio signals to a respective electric loudspeaker of the plurality of electric loudspeakers corresponding to a respective diagonal seat, from among the four seats, that is located at a diagonal position of a respective seat corresponding to the respective microphone.”

The claims supplied by the inventors are:

“1. A conversation assist apparatus for a vehicle that includes a plurality of microphones and a plurality of electric loudspeakers, each microphone of the plurality of microphones and each electric loudspeaker of the plurality of loudspeakers being arranged so as to correspond to a seat of four seats arranged in a rectangular manner in a passenger compartment of the vehicle, the conversation assist apparatus comprising: a signal processor configured to generate an audio signal by adding a delay to an output signal of a microphone of the plurality of microphones; a supplier configured to supply the generated audio signal to an electric loudspeaker of the plurality of electric loudspeakers that corresponds to a diagonal seat, from among the four seats, that is located at a diagonal position of a seat corresponding to the microphone; and a controller configured to control an amount of the delay based on a state of the vehicle.

“2. The conversation assist apparatus according to claim 1, wherein the state of the vehicle includes at least one of a noise level in the passenger compartment, a speed of the vehicle, a rotational speed of an engine in the vehicle, or a rotational speed of a fan of an air conditioner in the vehicle.

“3. A conversation assist apparatus for a vehicle that includes a plurality of microphones and a plurality of electric loudspeakers, each microphone of the plurality of microphones and each electric loudspeaker of the plurality of loudspeakers being arranged so as to correspond to a seat of four seats arranged in a rectangular manner in a passenger compartment of the vehicle, the conversation assist apparatus comprising: a signal processor configured to generate an audio signal based on an output signal of a microphone of the plurality of microphones; and a supplier configured to switch, upon reception of a howling noise occurrence signal indicative of occurrence of a howling noise, a destination of the generated audio signal from an electric loudspeaker of the plurality of loudspeakers that is a current destination of the generated audio signal to another electric loudspeaker of the plurality of electric loudspeakers that is different from the electric loudspeaker that is the current destination of the generated audio signal.

“4. The conversation assist apparatus according to claim 3, further comprising a detector configured to output the howling noise occurrence signal upon detecting the howling noise, wherein the supplier is configured to receive the howling noise occurrence signal from the detector.

“5. The conversation assist apparatus according to claim 3, further comprising: a manipulation switch; and an outputter configured to output the howling noise occurrence signal in response to a manipulation of the manipulation switch, wherein the supplier is configured to receive the howling noise occurrence signal from the outputter.
