Embodiment Construction

[0050] In order to make the purpose, technical solution and technical effect of the present invention clearer, specific embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] See figure 1 , the present invention provides an earphone 10 applied to a magnetic resonance system. The earphone 10 applied to a magnetic resonance system includes an amplifier circuit 100 and a loudspeaker 300 . The amplifying circuit 100 is used for amplifying the input audio signal. The speaker 300 is connected to the output end of the amplifying circuit 200 . The amplifying circuit 100 is an analog circuit and / or the speaker is made of non-magnetic material. The audio signal may be from an operating room. The doctor in the operating room can transmit the command audio signal to the pa...

Abstract

The invention discloses a headphone applied to a magnetic resonance system, and the magnetic resonance system. The headphone applied to the magnetic resonance system comprises an amplification circuitused for amplifying audio signals, and a loudspeaker connected with an output end of the amplification circuit; the amplification circuit is an analog circuit, and/or the loudspeaker is made from a non-magnetic material. Therefore, the electromagnetic interference caused by a digital power amplifier driving a load can be avoided, the compatibility between the headphone applied to the magnetic resonance system and magnetic resonance equipment is enhanced, and the sound transmission efficiency is increased.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to an earphone applied to a magnetic resonance system and a magnetic resonance system. Background technique [0002] When using large-scale medical equipment to perform image scanning or treatment on patients, the communication between doctors and patients is very important. Therefore, the earphones used in the magnetic resonance system are usually worn on patients. On the one hand, it can realize the communication between doctors and patients, on the other hand It can also reduce the noise of medical equipment during scanning or treatment. However, traditional earphones used in magnetic resonance systems usually use electromagnetic sounding units. When the magnetic resonance equipment is working, the magnetic elements in the sounding unit of such earphones applied to the magnetic resonance system will be affected by the magnetic resonance equipment, which will cause interferen...
