DETAILED DESCRIPTION

[0015] The utility model will be further described below in combination with specific embodiment and drawing.

[0016] As Figure 1As shown, a hearing meter earphone with state feedback function comprises a power unit 10, a control switch 20, a main controller 30, a power indicator 40, a communication unit 50, an oscillator 60, an attenuator 70, a first amplifier 80, a second amplifier 90, a first detection unit 100, a second detection unit 110, a left indicator 120, a right indicator 130, a left speaker 140 and a right speaker 150. The left indicator 120 and the left speaker 140 are installed on the left earphone part. The right indicator 130 and the right speaker 150 are installed on the right earphone part.

[0017] The power unit 10, the control switch 20 and the main controller 30 are sequentially electrically connected. The power unit 10 comprises a power controller 11, a battery seat 12 and a battery 13, and the battery 13 is detachably installed on the battery seat 12. The battery seat 12, the power controller 11 and the main controller 30 are sequentially electrically connected, and the whole hearing meter earphone is powered by the power unit 10. The battery 13 and the battery seat 12 are arranged in a detachable mounting structure, which can facilitate the replacement of the battery 13. The control switch 20 is used to control the on-off of the current of the power unit 10 and the main controller 30, that is, to control the power-on and power-off of the hearing meter earphone.

[0018] The power indicator 40 is electrically connected with the main controller 30. The power indicator 40 is used to prompt whether the hearing meter earphone is in the power-on state, and the power indicator 40 adopts an indicator lamp. When the hearing meter earphone is powered on, the indicator lamp is lit.

[0019] The communication unit 50 is electrically connected with the main controller 30. The communication unit 50 has a communication circuit and an antenna, etc., and is used to be wirelessly connected with the hearing meter, so as to receive the detection sound output instruction and transmit it to the main controller 30.

[0020] The main controller 30, the oscillator 60 and the attenuator 70 are electrically connected in sequence. The attenuator 70 is electrically connected with the first amplifier 80 and the second amplifier 90 respectively, the first amplifier 80 is electrically connected with the left speaker 140, and the second amplifier 90 is electrically connected with the right speaker 150. The oscillating part is a circuit which oscillates a signal of a frequency specified by a control signal and outputs the signal as a test tone signal. The attenuator 70 is a circuit which reduces the amplitude of the test tone signal output by the oscillating part at a reduction rate specified by the control signal. The first amplifier 80 and the second amplifier 90 are circuits which increase the amplitude of the test tone signal output by the oscillating part at an amplification rate specified by the control signal. The left speaker 140 and the right speaker 150 are used to output test tones respectively. In operation, the main controller 30 supplies a control signal corresponding to a test tone output instruction to the oscillating part, the attenuator 70 and the first and second amplifiers 90, and outputs a test tone signal (a test tone signal of a specified frequency and sound pressure level) specified by the test tone output instruction through the left speaker 140 and the right speaker 150.

[0021] The first detection unit 100 is electrically connected with the first amplifier 80 and the main controller 30 respectively, the second detection unit 110 is electrically connected with the second amplifier 90 and the main controller 30 respectively, and the left indicator 120 and the right indicator 130 are electrically connected with the main controller 30 respectively. The first detection unit 100 and the second detection unit 110 are used to detect whether the first amplifier 80 and the second amplifier 90 are working normally, and feedback through the left and right indicators 130. The medical staff can know whether the speakers are working normally and which side of the speaker is working according to the left and right indicators 130, so as to help the medical staff to judge whether the audiometer earphone is in a normal test state, so as to ensure the accuracy of the test result. Connecting the first detection unit 100 and the second detection unit 110 to the first amplifier 80 and the second amplifier 90 can not only detect the first amplifier 80 and the second amplifier 90, but also detect whether the oscillator 60 and the attenuator 70 are working normally. When any of the components fails, the left and right indicators 130 do not light up, so that the medical staff can know that the audiometer earphone has failed in time. The left indicator 120 and the right indicator 130 are both light-emitting display devices. When the speaker on one side emits sound, the indicator on the corresponding side lights up to indicate that the speaker on the side is working normally. When the oscillator 60, the attenuator 70, the first amplifier 80 or the second amplifier 90 fails, the indicator on the corresponding side cannot light up to indicate that the audiometer earphone has failed.

[0022] The above examples are only used to facilitate the illustration of the present application, and any person skilled in the art can make equivalent examples by making partial changes or modifications within the scope of the technical features disclosed in the present application without departing from the technical features of the present application, and the equivalent examples still belong to the scope of the technical features of the present application.
