摘要： PROBLEM TO BE SOLVED: To provide a vehicle presence notification device that allows notification sound emission means to be easily mounted on a vehicle.SOLUTION: In dead space around a coil housing part 6 of a flat electromagnetic alarm 5 is installed a small horn speaker 3 (a small speaker 1 + an acoustic tube 2) as notification sound emission means. Mounting the flat electromagnetic alarm 5 on a vehicle enables the small horn speaker 3 to be mounted on the vehicle at the same time, which enhances capacity of mounting the notification sound emission means on the vehicle. In addition, as the small horn speaker 3 is installed in the dead space around the coil housing section 6, the flat electromagnetic alarm 5 can be kept thin and travelling wind flowing into a heat exchanger (a radiator or the like) is not affected. Further, the dead space around the coil housing section 6 is used to curve the acoustic tube 2 so as to extend sound of the acoustic tube 2, thereby enhancing a bass-sound amplification effect by the acoustic tube 2.
摘要翻译：要解决的问题：提供允许通知声音发射装置容易地安装在车辆上的车辆存在通知装置。解决方案：在扁平电磁报警器5的线圈壳体部分6周围的死区中安装有小喇叭扬声器3 （小扬声器1 +声管2）作为通知声发射装置。将平面电磁报警器5安装在车辆上能够同时将小喇叭扬声器3安装在车辆上，这增强了将通知声音发射装置安装在车辆上的容量。此外，由于小喇叭式扬声器3安装在线圈收纳部6周围的死角处，因此平坦的电磁报警器5能够保持薄型化，并且流入热交换器（散热器等）的行驶风不受影响。此外，线圈容纳部6周围的死角被用于使声管2弯曲，以延伸声管2的声音，从而增强声管2的低音声音放大效果。

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic alarm which has a long lifetime, and is free from failure even after long-term use.SOLUTION: Two alarm tone generators 1 are provided on one spiral sound pipe 2, and alarm tones generated by the two alarm tone generators 1 are emitted to the outside via one sound pipe 2. Since the two alarm tone generators 1 are provided to one electromagnetic alarm, the load of each alarm tone generator 1 for obtaining sound pressure of one electromagnetic alarm is reduced. As a result, currents of respective alarm tone generators 1 are reduced in comparison with prior arts; and contact loads of respective interrupters 4 are reduced; and the burden on an insulating part 14 for giving driving force to the interrupters 4 is reduced. Therefore, failure of the electromagnetic alarm can be prevented even when the electromagnetic alarm is used for a long period of time in a use environment where a use frequency of the electromagnetic alarm is high. That is, the lifetime of the electromagnetic alarm can be extended and the reliability of the electromagnetic alarm can be improved.
摘要翻译：要解决的问题：提供寿命长的电磁报警器，即使在长期使用后也不会发生故障。解决方案：一个螺旋音管2上设有两个报警音发生器1，由两个报警音发生器1经由一个声管2发射到外部。由于两个报警音发生器1被提供给一个电磁报警器，因此减少了用于获得一个电磁报警器的声压的每个报警音发生器1的负载。结果，与现有技术相比，各个报警音发生器1的电流减小; 并减少各断流器4的接触负荷; 并且减小了用于向断续器4施加驱动力的绝缘部分14的负担。因此，即使在电磁报警器的使用频率高的使用环境中长时间使用电磁报警器，也能够防止电磁报警的故障。也就是说，可以延长电磁报警的寿命，并且可以提高电磁报警的可靠性。

摘要： PROBLEM TO BE SOLVED: To prevent the deterioration of the performance of an ultrasonic speaker caused by a front grill without impairing the design performance of the front grill.SOLUTION: In a parametric speaker, each grill bar 2 in the front range of the ultrasonic speaker 5 for emitting an ultrasonic wave to the vehicle outside has a shape in which the lower side of a substantially U-shaped cross section is cut and composed of only a curved projection 2a and an band plate 2b on the top side of the curved projection and provided to have a shape in which a band plate 2b on the bottom side of the curved projection is cut. By this, the direction of the ultrasonic wave hitting against the inner surface of the grill bar 2 is changed downward, and then, changed again to the vehicle front by the outer surface of the grill bar 2 below it, and the ultrasonic wave is emitted toward the vehicle front. As a result, the deterioration the performance caused by the rearward return of a part of the ultrasonic wave can be suppressed, thereby enhancing the substantial performance of the ultrasonic speaker 5. Even if the shape is formed in a state that the band plate 2b on the bottom side is cut, the shape is unrecognizable from the external appearance of the front grill 3, thereby not affecting the design performance of the front grill 3.
摘要翻译：要解决的问题：为了防止由前格栅引起的超声波扬声器的性能的劣化，而不损害前格栅的设计性能。解决方案：在参数扬声器中，用于向车外发射超声波的超声波扬声器5的前方范围内的每个格栅条2具有大致U字形截面的下侧被切割的形状并且仅在弯曲突起的顶侧上的弯曲突起2a和带板2b构成，并且具有其中切割弯曲突起的底侧上的带板2b的形状。由此，超声波撞击格栅2的内表面的方向向下变化，然后再通过格栅2的外表面再次改变为车辆前方，并且发射超声波朝着车前方结果，可以抑制由超声波的一部分的向后返回引起的性能的劣化，从而提高超声波扬声器5的实质性能。即使形状是在带板2b接通的状态下形成的底部被切割，该形状不能从前格栅3的外观识别，从而不影响前格栅3的设计性能。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a vehicle presence reporting device capable of widening the directivity of reporting sound generated by reporting sound generation means, and enabling a pedestrian to easily hear the reporting sound.SOLUTION: As reporting sound generation means, a speaker 3 for generating a reporting sound, a first acoustic pipe 11 for emitting a positive-phase reporting sound generated in front of the speaker 3, and a second acoustic pipe 12 for emitting a negative-phase reporting sound generated in rear of the speaker 3 are used. This configuration synthesizes the positive-phase reporting sound and negative-phase reporting sound, widening directivity of the reporting sound to promote the reporting sound to reach a pedestrian and enhance safety. Further, a resonance frequency of the first acoustic pipe 11 and that of the second acoustic pipe 12 are set mutually in opposite phases at the same frequency. This enables reliable widening of the directivity of a resonance sound (a part of reporting sound) caused by the resonance frequency. Further, a reporting sound generated in front and back of the speaker 3 is emitted through the first and second acoustic pipes 11 and 12, that increases emission energy of the reporting sound.

摘要： PROBLEM TO BE SOLVED: To improve mountability of a trumpet type alarm horn mounted with a small speaker to a vehicle by thinning the alarm horn.SOLUTION: A spiral horn 3 includes: an acoustic outlet α; a dead-space acoustic line 4 using dead space β of the spiral horn 3; and a sub-acoustic outlet γ for emitting outward sound transmitted into the dead-space acoustic line 4. A front face of the spiral horn 3 is arranged in a nearly flat surface, and in a rear surface of the spiral horn 3 is arranged a rear protruding part. A stay for mounting for a vehicle is secured on an uneven surface of an outer circumference of a coil housing part. A small speaker 1 is installed inside the spiral horn 3. This enables thickness of a trumpet type alarm horn mounted with the small speaker 1 to be nearly as thin as an existing flat electromagnetic alarm horn, so that even vehicles that could ever mount only the flat electromagnetic alarm horn can mount "the trumpet type alarm horn mounted with the small speaker 1."

摘要： PROBLEM TO BE SOLVED: To provide a vehicle presence notification device such that a compact speaker and a drive amplifier for notice sound generation mounted on a vehicle horn are not broken with "a compressive wave generated by an alarm tone generation part".SOLUTION: A compact speaker 1 is provided at a position off the spiral center (horn entrance β) of a spiral acoustic tube 4. Namely, the compact speaker 1 is provided halfway in a sound channel of the spiral acoustic tube 4. Specifically, the compact speaker 1 is provided "within a range of rough sound density" and "on a side close to the horn entrance β" in alarm sound generation in the spiral acoustic tube 4. Consequently, "a compression wave of high compression as an alarm sound" that an alarm sound generation part generates is prevented from reaching the compact speaker 1 directly, and the compact speaker 1 and drive amplifier are thereby prevented from being broken so as to effectively enhance reliability of the vehicle presence notification device.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle existence notifying device capable of arbitrarily controlling the directivity of notifying sounds even if a dynamic speaker is mounted to a sounding tube of an electromagnetic alarm.SOLUTION: When a piezoelectric speaker 3 is mounted to a spiral sounding tube 2 of an electromagnetic alarm 1, the directivity of notifying sounds is governed by the opening shape and the opening direction of a horn exit α of the spiral sounding tube 2. In the sounding tube 2 at its sites different from the horn exit α, communication holes β are formed for making the inside communicate with the outside for releasing the notifying sounds not only from the horn exit α but also from the communication holes β. Depending on positions (in opening directions of the communication holes β), the number and sizes of the communication holes β, releasing directions and volumes of the notifying sounds can be controlled. Namely, the directivity (arrival distance) of the notifying sounds can be arbitrarily controlled by forming the communication holes β.

摘要： PROBLEM TO BE SOLVED: To prevent an ultrasonic speaker from being heated by a heat exchanger without deteriorating the heat radiation of the heat exchanger.SOLUTION: In view of forward of the vehicle, a vehicle horn 3 is disposed between the ultrasonic speaker 5 and the heat exchanger 1. As a result, the heat of the heat exchanger 1 is blocked by the vehicle horn 3, the temperature rise of the ultrasonic speaker 5 is prevented, troubles of changing the ultrasonic frequency by heat is evaded, and decrease of the product life of the ultrasonic speaker 5 by heat is prevented. The heat radiation of the heat exchanger 1 does not deteriorate even if the ultrasonic speaker 5 is mounted since the ultrasonic speaker 5 overlaps the vehicle horn 3 in view of forward of the vehicle. As the ultrasonic speaker 5 is installed in vehicle horn 3, the vehicle mountability of the ultrasonic speaker 5 can be improved. The phases of ultrasonic waves become equal, since a plurality of piezoelectric speakers 22 are disposed to the coplanar of a support plate 23, and the range of the ultrasonic wave can be extended.
摘要翻译：要解决的问题：为了防止超声波扬声器被热交换器加热而不会使热交换器的热辐射恶化。
解决方案：鉴于车辆前方，在超声波扬声器5和热交换器1之间设置车辆喇叭3，结果，热交换器1的热量被车辆喇叭3阻挡，防止了超声波扬声器5的温度上升，避免了通过热量改变超声波频率的麻烦，并且防止了超声波扬声器5的热量的使用寿命的降低。即使超声波扬声器5从车辆前方观看，超声波扬声器5与车顶3重叠，因此即使安装超声波扬声器5，热交换器1的散热也不会劣化。当超声波扬声器5安装在车辆喇叭3中时，能够提高超声波扬声器5的车辆安装性。超声波的相位相等，因为多个压电扬声器22被设置在支撑板23的共面上，并且超声波的范围可以延长。版权所有（C）2012，JPO＆INPIT

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.
