New description: [New technical field] This creation is about anti-noise earmuffs, especially anti-noise earmuffs with Bluetooth module and audio signal processing device. [Prior Art] It is known that in a high-decibel workplace, for example, a real-shot or air-robbed shot. Before the shooter shoots, he wears an anti-noise earmuff on his head to cover the shooter's ears. For example, the national new patent No. 0922Π679 “audio signal detection device” is combined with the aforementioned anti-noise ear. Inside the cover, it uses the audio signal attenuation function in the anti-noise earmuffs as anti-noise. The sound of the sound during shooting does not directly damage the eardrum inside the ear. However, the device does not have a personal communication or music transmission. Therefore, it is necessary to research and improve the provider to communicate with the outside world and listen to music. In addition, the general Bluetooth system call device is disturbed by noise in the noise place. For example, the above shooting field environment grabs the sound of the contact, so it is impossible to contact the person who is shooting or to talk to (4); for example, Lin _ When the age of listening to music 5 mobile phone 'have to take off the anti-noise earmuffs, so the use of the hemp [new content] too creative - the purpose is to solve the above-mentioned lack of 'avoid the lack of existence, this is done _-audio Wei Wei County will enter the anti-noise earmuffs in the ancient eight: the audio signal is attenuated to below 79db, to ensure that the shot = will pay an instant high audio signal rain injury. Another purpose of the film is to provide a user's cover and Wei music and the outside world are subject to noise. For the purpose of the above, the present invention provides an anti-noise earmuff with a Bluetooth module and an audio signal M417137 processing device, including: an audio signal processing unit of more than one time to receive external audio signals; a mixing unit electrically connected to the audio signal processing unit for receiving and processing the audio signal output by the audio signal processing material; the amplifying unit is electrically connected to the mixing unit for receiving and amplifying The audio signal output by the mixing unit; and a Bluetooth module is electrically connected to the mixing unit. The audio signal processing unit comprises: an audio receiver, a first, an and amplifying circuit, a second-stage amplifying circuit, a current amplifying circuit, a detecting circuit, a switching circuit and an adjusting circuit.

Audio signal output. The switch circuit 16 is any one of a transistor or a diode. When the switch circuit 16 receives the output of the detector circuit 15 and is less than the IV voltage, the switch circuit 16 is turned on, and the first amplifier circuit 12 is amplified. The audio signal can pass through the switch circuit 16. The adjustment circuit is a variable resistor for adjusting the audio signal passing through the switch circuit 16 to control the output volume. = Bud module 2, electrical connection - antenna 2 - blue wind 2 2 formed by the volume adjustment circuit 23, the Bluetooth module 2 is electrically connected to the Γ, right channel mixer 3 32. The Bluetooth bud = receiving mobile communication device (not shown) is processed by the 3^2 transmission module 2, and the left and right channel mixers are not allowed to let the user hear the remote end wanted. The sound of the material transmitted by the communication device or received by the portable cockroach 22, the sound emitted by the (3) bud ceremony* is emitted by the blue microphone dish, and 2 is then transmitted by the sky and line 21 to The portable 5 M417137 mobile communication device. The mixing unit j′ is composed of left and right channel mixers 3 and 32, and the audio signals output by the audio signal processing unit 1 and the t-bud module 2 are respectively input to the left and right sound mixes. On the 31, 32. The amplifying unit 4 is composed of left and right audio amplifying circuits 41 and 42 for receiving the audio signal output by the mixing unit 3, and is processed by the amplifying unit 4, and then output to the left and right speakers (not shown in the figure) Show). Referring to Figure 2, a waveform comparison diagram of the circuit of the audio signal processing unit of the first embodiment and the drawing of the present invention is shown. As shown in the figure: When the shooter (user) starts shooting, after the audio receiver n receives the external audio signal, it is immediately output to the first-stage amplifying circuit 12, and the first-stage amplifying circuit 12 amplifies the audio receiving. The audio signal received by the device is output to the second-stage amplifying circuit, and after the current amplifying circuit and the detecting circuit 15 are processed, if the signal is greater than 1V, the switch circuit 16 is turned off. The amplified audio signal of the first stage amplifying circuit 12 cannot pass through the switching circuit 16. If the signal output by the detection circuit 15 is less than the IV voltage, the switch circuit 16 is turned on, and the audio signal amplified by the first-stage amplifier circuit 12 passes through the switch circuit 16, and then the adjustment circuit 17 and the sound is mixed. After the unit 3 and the amplifying unit 4 process, the output is output to the speaker, that is, the audio signal received by the audio receiving unit 1 can be seen. Therefore, the sound signal output by the speaker does not cause excessive output frequency and damages the user's eardrum, so as to ensure that the eardrum inside the ear of the shooter (user) does not suddenly overshoot the audio signal and hurt the ear.曰In the noise place, you can not take off the anti-sound earmuffs, use the internals, the monitor buds pull the level 2 to connect the communication device to pass the music 'or through the Bluetooth model' and 2 to talk to the mobile communication device M417137 _ See $ 3 11, is a schematic diagram of the second embodiment of the present creation. As shown in the figure, this embodiment is substantially the same as FIG. 1, and the difference is only in the second embodiment.
