Electromagnetic type bone conduction telephone receiver

Abstract

The invention relates to an electromagnetic type bone conduction telephone receiver which comprises a shell (1) and a cover (2); a lower pole shoe (3) is fixed in the shell (1) and is provided with magnetic steel (4) and a coil (5); an upper pole shoe (6) is fixed on a vibration sheet (7) and arranged above the magnetic steel (4); and the vibration sheet (7) is fixed on the shell (1). In the invention, the sound can be conducted by using the property that human bones can conduct sound to conduct sound; when in use, the telephone receiver is put on cheekbones in front of ears so that the wholeears can be exposed to an environmental sound field; and sound signals sent by communication equipment are converted by the telephone receiver into mechanical vibration signals which are directly transmitted into human skulls, and then to cochlea and finally to human brains; in such a way, human eardrums are directly exposed to the environmental sound field and receive information transmitted by air vibration at all times, while communication information is transmitted by the skulls, thereby achieving the transmission of both the environmental information and the communication information.

Description

technical field [0001] The invention relates to an electromagnetic bone conduction receiver. Background technique [0002] The receivers currently used in various communication devices are all air conduction, that is, through air conduction, the sound pressure acts on the eardrum of the recipient, and the eardrum passes through the human ossicles and cochlea, and finally transmits the sound to the human brain. The main problem of the air conduction receiver is that it must be buckled on the pinna (earphone) or blocked at the mouth of the ear canal (earplug) when using it. In this way, when a person wears the earphone or earplug, he cannot effectively listen to and analyze the sound coming from the earphone. The sound information of the surrounding environment makes it impossible to satisfy some conditions of use that must not only hear the voice signal from the communication device but also understand the environment information.

Problems solved by technology

In this way, the human eardrum is directly exposed to the environmental sound field and can receive the information transmitted by air vibration at any time, while the communication information is transmitted by the skull, which solves the problem of both communication and environmental information.
