摘要： PROBLEM TO BE SOLVED: To provide an on-vehicle handsfree device capable of disallowing howling phenomenon to occur with reduced cost.SOLUTION: An on-vehicle handsfree is used by a crew member α (driver) to hold a telephone conversation with a telephone opposite party without touching the mobile phone, and includes: a microphone 1 for picking up the voice of the crew α; and a parametric speaker 2. The parametric speaker 2 includes: an ultrasonic speaker 3; an ultrasonic modulation circuit 4; and an amplifier circuit 5, for radiating "a supersonic wave in which voice signal of the telephone opposite party is undergone ultrasonic modulation" to the crew member α. Then, "voice (sound wave) of the telephone opposite party" is given to the crew α by self-modulation of the supersonic wave at the crew member α side. As a result, the microphone 1 does not pick up "the voice of the telephone opposite party, thereby preventing howling phenomenon from occurring. As such, howling phenomenon can be avoided without using an expensive echo cancellation circuit and the cost for the on-vehicle handsfree device free from howling phenomenon can be reduced.

摘要： PROBLEM TO BE SOLVED: To prevent a notification sound generation speaker mounted on a trumpet type alarm and a circuit which places the notification sound generation speaker in operation from being broken with a "resonance alarm sound of high sound pressure" generated in a resonance trumpet.SOLUTION: A mounting place for a notification sound generation speaker 1 at a vehicle front part is secured by mounting the notification sound generation speaker 1 on a trumpet type alarm 2, and a notification sound generated by the notification sound generation speaker 1 is emitted to outside a car through a resonance trumpet 4. The notification sound generation speaker 1 and resonance trumpet 4 are partitioned off with a thin film X, which suppresses transmission of a sound wave of resonance frequency of the resonance trumpet 4 and transmits a sound wave of frequency of the notification sound. Consequently, the notification sound generated by the notification sound generation speaker 1 can be emitted to outside the car through the resonance trumpet 4, the sound pressure of a resonance alarm sound operating on the notification sound generation speaker 1 can be lowered, and the notification sound generation speaker 1 and a circuit are prevented from being broken so as to improve reliability.
摘要翻译：要解决的问题：为了防止安装在小号型报警器上的通知声音产生扬声器和使通知声音产生扬声器工作的电路被共振喇叭中产生的“高声压的共鸣报警声”中断。解决方案：通过将通知声音产生扬声器1安装在喇叭式报警器2上，确保车辆前部的通知声音产生扬声器1的安装位置，并且将由通知声音产生扬声器1产生的通知声音发射到外部汽车通过共鸣喇叭4.通知声音产生扬声器1和共鸣喇叭4用薄膜X分隔开，该薄膜X抑制共鸣喇叭4的共振频率的声波的传播，并且发送频率为通知声音。因此，由通知声音产生扬声器1产生的通知声音可以通过共鸣喇叭4发射到汽车外部，可以降低在通知声音产生扬声器1上操作的共鸣报警声的声压，并且通知声音防止一代扬声器1和电路被破坏，从而提高可靠性。

摘要： PROBLEM TO BE SOLVED: To suppress cost of a vehicle presence notification apparatus that can generate bass.SOLUTION: Since a piezoelectric loudspeaker 1 is a small dynamic speaker, reproduction of bass is difficult in a unit. However, the piezoelectric loudspeaker 1 is mounted on a swirl acoustic tube 4 of an electromagnetic alarm 2, and a notification sound is emitted to a center of the swirl acoustic tube 4. As a result, a low frequency component where a piezoelectric loudspeaker 1 is generated can be emitted by amplifying by the swirl acoustic tube 4. As a result, acoustic pressure of bass can be raised as well as a case to use a large scale dynamic loudspeaker (woofer etc.), and the cost of the vehicle presence reporting device that can generate the bass can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle presence notification apparatus that makes the false engine sound similar to a real engine sound by controlling the directivity of the false engine sound without increasing the number of speakers.SOLUTION: A control circuit 2 of a vehicle presence notification apparatus increases the ratio of the high-pitched frequency component to the low-pitched frequency component in the false engine sound as the speed of the vehicle is raised. The directivity of false engine sound generated on the front side of a vehicle can be narrowed according to an increase in vehicle speed, and the false engine sound can be made realistic. A rate of a frequency component of false engine sound is changed to control the directivity. Because many speakers are not necessary, the cost can be reduced and it becomes easy to mount the vehicle presence notification apparatus which can control the directivity of the false engine sound.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle presence notification apparatus allowing "recognition of stopped vehicle", "recognition of traveling vehicle", "recognition of stop of traveling vehicle", and "recognition of start of stopped vehicle" even in a vehicle without engine sound.SOLUTION: "Simulated idling sound" is generated from a vehicular horn and a parametric speaker during the stop of a vehicle. "Simulated traveling sound" is generated from the vehicular horn and the parametric speaker during the travel of the vehicle. The "simulated idling sound" allows a pedestrian to recognize the stopped vehicle, the "simulated traveling sound" allows a pedestrian to recognize the traveling vehicle, the change of the "simulated traveling sound" to the "simulated idling sound" allows a pedestrian to recognize the stop of the traveling vehicle, and the change of the "simulated idling sound" to the "simulated traveling sound" allows a pedestrian to recognize the start of the stopped vehicle. Since the "simulated idling sound" and the "simulated traveling sound" are smoothly changed, the "stop of the traveling vehicle" and the "start of the stopped vehicle" are notified without the sense of incongruity.

摘要： PROBLEM TO BE SOLVED: To provide an artificial engine sound generator that simplifies storage data and reduces arithmetic loads for producing artificial engine sound.
SOLUTION: The artificial engine sound generator produces an artificial engine sound by generating "many frequency signals continuing at intervals of 4 Hz". Therefore, the storage data for producing the artificial engine sound can be simplified, and the arithmetic load for producing the artificial engine sound can be minimized. The frequency range of "many frequency signals continuing at intervals of 4 Hz" is suppressed within "frequency range from maximum sound pressure to -10 dB" of "actual engine sound", so that the number of frequency signals is reduced and arithmetic load can be reduced. Further, the frequency characteristics of "many frequency signals continuing at intervals of 4 Hz" is processed to the frequency characteristics of "actual engine sound of specific vehicle type", so that the artificial engine sound can be made to resemble "actual engine sound of specific vehicle type".

摘要： PROBLEM TO BE SOLVED: To achieve a function except generation of informing sound by a vehicle presence informing device 1.
SOLUTION: In this vehicle presence informing device 1, the informing sound is generated by radiating an ultrasonic wave into air based on an ultrasonic wave signal modulated according to audible sound by using a plurality of ultrasonic wave transducers 3. One of the plurality of ultrasonic wave transducers 3 is made as a transducer 7 for transmission and reception capable of receiving the ultrasonic wave in addition to the transmission of the ultrasonic wave. When vehicle speed is a prescribed value or more, the transducer 7 is made to function as an ultrasonic wave sensor. As a result, the vehicle presence informing device 1 can be utilized as the ultrasonic wave sensor 7 for measuring a distance from an obstacle, also when informing sound is not required to be generated since the vehicle speed is fast.

摘要： PROBLEM TO BE SOLVED: To provide a personal acoustic system for a vehicle, in which only "the specific crew (e.g., only a driver)" is allowed to listen to audible sounds (voices, music or the like). SOLUTION: An ultrasonic wave amplitude-modulated in accordance with an audio signal is radiated from an ultrasonic loudspeaker 1 for the head installed above the head of a driver only toward the head α of the driver. Then, an amplitude component contained in the ultrasonic wave is demodulated not in the air but in the head α (cranial bones or the like) of the driver, and the head α (cranial bones or the like) of the driver can be vibrated by the amplitude component contained in the ultrasonic wave, so that only the driver is allowed to listen to "audible sounds" based on the "audio signal that becomes a sound source". Thus, only the driver can obtain audio information of navigation voices or traffic information or only the driver can enjoy music or radio without troubling the other crew.
