Non-directional radio telephone receiver

Abstract

The invention discloses a non-directional radio telephone receiver which comprises an MCU (Microprogrammed Control Unit), a gravity sensor, a selector switch, a first microphone, a second microphone, a first speaker and a second speaker, wherein the gravity sensor is connected with the MCU, and used for sending sensing data to the MCU; the selector switch is connected with the MCU, and is used for connecting a communication line of the first microphone and the first speaker under the control of the MCU or connecting a communication line of the second microphone and the second speaker; and the first microphone and the first speaker are respectively arranged at two ends of the receiver, the second microphone and the second speaker are respectively arranged at two ends of the receiver, the first microphone and the second microphone are positioned at opposite sides of the receiver, and the first speaker and the second speaker are positioned at opposite sides of the receiver. The non-directional radio telephone receiver accords with the human engineering principle, and can realize a communication function in two directions.

Description

Technical field [0001] The invention relates to a telephone receiver, in particular to a radio receiver structure. Background technique [0002] The appearance of the telephone has greatly facilitated the communication between people. At present, the telephone receiver used in the building intercom system has the following characteristics: [0003] (1) Considering that the handset is easy to access regardless of the body's left and right sides, most of the telephone handsets are now placed vertically. This structure makes it possible to turn the wrist when accessing, regardless of whether the handset is placed on the left or right. The earpiece is not ergonomic; [0004] (2) Based on the above factors, there are currently a few handsets that are placed horizontally, but due to the different outlet positions of the handset crystal head, this placement method cannot be used for both left and right hands; [0005] (3) As for the wireless earpiece, the internal microphone and speaker are...

AI Technical Summary

Problems solved by technology

[0003] (1) Considering that it is convenient to take the handset no matter on the left or right side of the body, most of the telephone handsets are now placed vertically. Pick up the handset, which is not ergonomic;

[0004] (2) Based on the above factors, there are currently a small number of handsets that are placed horizontally, but due to the different outlet positions of the handset crystal head, this placement method cannot be used for both left and right hands;

[0005] (3) As for the wireless handset, the internal microphone and speaker are separated and have obvious directionality, that is, the speaker and microphone cannot be used upside down, otherwise you will not be able to hear the sound, and you will not be able to transmit the sound to the other party ;

[0006] (4) In addition, most portable handset chargers use DC charging, and the direction of the positive and negative poles must not be reversed, otherwise the handset will be damaged, which also enhances the inconvenience of using the phone handset

[0007] Based on the above analysis, the existing telephone handsets cannot meet the requirements of ease of use and need to be improved
