Description

Alarm with high-efficient warning effect

Technical Field

The utility model relates to an alarm technical field specifically is an alarm with high-efficient warning effect.

Background

In modern families, many people cause fire accidents because of not knowing family safety general knowledge, so that happy families at the good end are turned to the eyes to be destroyed once, some of the happy families lead to family death, and once a household fire of residents occurs, serious casualties and property loss can be caused due to improper disposal and slow alarm, therefore, the installation of an alarm at home is very important for preventing the occurrence of the standard fire.

The alarm gives out sound warning when giving an alarm, the sound has three basic characteristics, namely loudness, tone and tone color, the tone is usually called as high or low, the tone is related to the vibration frequency of an object, and the higher the frequency is, the higher the tone is; the smaller the frequency, the lower the pitch. However, the sensitivity of the world products to different frequency tones is different, and each has a receiving range. Meanwhile, the strength of sound which can be sensed by human ears is called loudness, which is related to the vibration amplitude of an object, and the larger the amplitude is, the larger the loudness is; the smaller the amplitude, the smaller the loudness; meanwhile, the loudness is also related to the distance from the sound source, namely the closer the sound source is, the greater the loudness is; the farther from the sound source, the smaller the loudness. The loudness is a somatosensory expression of sound received by human ears, but the loudness is weakened by the influence of the distance of a sound source and an obstacle, and the tone is a factor for determining whether the human ears can receive the sound and determining the strength of the sound receiving sensitivity, and has certain penetrating performance, so that the effect of receiving the sound by the human ears cannot be judged according to the strength of the loudness of the sound.

When people have a rest at night, particularly at midnight, people are in a deep sleep state, if an alarm occurs, the alarm is difficult to awaken people who sleep deeply because the alarm is blocked and weakened by the wall surface and the distance between sound sources, so that a lot of fires at night often cannot be alarmed in time to cause slow rescue, thereby forming a disaster, most of current alarm devices reported on the market pay attention to the loudness of sound, and are unaware of the importance of the tone of the sound, so that the existing alarm devices have serious alarm error zones, and cannot play an ideal alarm role.
