specific Embodiment approach 1

[0011] Specific implementation mode one: combine figure 1 with figure 2 Describe this embodiment, a device for sensing the surrounding environment described in this embodiment includes N object detectors 1, and is characterized in that it also includes a microcomputer processing chip 2 and N moving coil speakers 3, and the N The object detectors 1 correspond to N moving coil speakers 3 respectively, the detection signal output ends of the N object detectors 1 are connected to the detection signal input ends of the microcomputer processing chip 2, and the N object detectors 1 are used to detect different The distance and relative speed of the direction object, the N sound control signal output ends of the microcomputer processing chip 2 are respectively connected to the sound control signal input ends of N moving coil speakers 3 .

[0012] When the device for sensing the surrounding environment described in this embodiment is in use, N object detectors 1 and N moving coil spe...

specific Embodiment approach 2

[0014] Embodiment 2: This embodiment is a further limitation of the N object detectors 1 in the device for sensing the surrounding environment described in Embodiment 1. In this embodiment, the N object detectors 1 are ultrasonic detectors , radar detector or laser detector.

specific Embodiment approach 3

[0015] Specific Embodiment 3: This embodiment is a further limitation of the moving coil speaker 3 in a device for sensing the surrounding environment described in Embodiment 1 or 2. In this embodiment, the air waves emitted by the moving coil speaker 3 The frequency range is 20Hz ~ 20KHz.

[0016] When the frequency of the air wave exceeds the above range, the human body will not perceive it clearly.

Abstract

The invention provides a device for sensing the surrounding environment, and relates to the field of sensing technologies. The device aims to solve the problems that an existing visual impairment auxiliary instrument can not be applied to people who are disabled both in vision and hearing, muscle numbness or spasm of a user can occur if the existing visual impairment auxiliary instrument is used for a long time, and electrical brain simulation occurs. According to the device, N object detectors detect the distances and relative speeds of objects in different directions, a micro computer processing chip converts signals detected by the object detectors to voice control signals and sends the voice control signals to a moving-coil loudspeaker, the moving-coil loudspeaker gives out air billows of different frequencies and vibration rhythms, and a user judges the distance and speed of objects in different directions according to the frequencies and the vibration rhythms of the air billows. The user does not need to receive voice signals with ears, so that people who are disabled both in hearing and vision can also use the device, the air billows are different from mechanical vibration or currents, muscle numbness or spasm can not occur even the user uses the device for a long time, and pricking feeling certainly can not occur. The device is used for assisting the visual impaired people in sensing the surrounding environment.

Description

technical field [0001] The present invention relates to perception technology. Background technique [0002] At present, common assistive devices for visual impairment mainly use sound, mechanical vibration and electrical stimulation to provide feedback to the user. The use of audio feedback is not suitable for persons who are also hearing impaired. The general mechanical vibration mode is simple, and it is easy to cause muscle numbness or spasm when used for a long time. The electrical stimulation method needs to select places with dense nerves such as the tongue, and at the same time, the electric current will produce tingling pain, which will bring pain to the user. Contents of the invention [0003] The purpose of the present invention is to provide a device for sensing the surrounding environment in order to solve the problems that the current aids for visual impairment are not suitable for people with hearing impairments, muscle numbness or spasms, and current stim...
