Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, the embodiment of the present invention includes:

the utility model provides a neck formula earplug intercom of hanging neck, includes signal receiving terminal 1, function connecting wire 2, control box 3, supply apparatus 4 and hang neck connecting piece 5, signal receiving terminal 1 be connected with supply apparatus 4's one end through function connecting wire 2 respectively, control box 3 set up on one of them function connecting wire 2, the other end of supply apparatus 4 between be connected through hanging neck connecting piece 5. In this embodiment, the number of the signal receiving terminals 1 and the number of the power supplies 4 are both 2.

In the foregoing, signal receiving terminal 1 adopt and fall the earplug of making an uproar, wear in the natural and comfortable state, reached fine noise reduction effect, life cycle is longer than ordinary earplug, can prevent the noise to the injury of ear simultaneously, can also very clear hear the content of talkbacking. In the embodiment, the shape and the material of the noise reduction earplug are not limited, and the use of the half-in-ear earplug is not excluded, so that the noise reduction earplug is comfortable to wear, cost-saving and environment-friendly.

Wherein, the neck connecting piece 5 adopts an arc-shaped structure made of flexible materials. The appearance of hanging neck connecting piece 5 is designed according to the comfort level of people's neck completely to wear again on the neck in natural comfortable state, conveniently wear, the travelling comfort is good. In this embodiment, the shape and material of the neck hanging connecting piece 5 are not limited, and the neck hanging connecting piece is not comfortable to wear, cost saving and environment friendly.

Furthermore, the functional connecting wire 2 is internally provided with an antenna (not shown) which is made of flexible materials, the antenna can be bent randomly and is not easy to break, the service life is prolonged, the antenna and the functional connecting wire 2 are arranged between the control box 3 and the power supply 4, the antenna is longer, and the communication distance is longer.

As shown in fig. 2, a connected small-sized control module chip 31 or a rechargeable battery 32 is disposed in the control box 3, the rechargeable battery 32 is located at the bottom of the small-sized control module chip 31, and the rechargeable battery 32 supplies power to the headset interphone. Wherein, still be provided with the noise reduction module in the small-size control module chip 31, reach the effect of making an uproar of falling, fall the effect that the earplug of making an uproar reaches down to fall for the noise reduction effect is better, and tone quality is clear, can be clear through talkbacking the required information of transmission.

In this embodiment, the small control module chip 31 has a size of 70 × 10 × 3.2mm, and is the smallest module in the industry at present, so that the size and weight of the small control module chip are further reduced, and the small control module chip is convenient to carry.

As shown in fig. 3, the control box 3 is provided with a sleep button 33, a volume adjuster 34 and a frequency adjuster 35, and the sleep button 33, the volume adjuster 34 and the frequency adjuster 35 are all connected with the small control module chip 31. When the control box 3 is internally provided with the rechargeable battery 32, the control box 3 is provided with the USB interface 36, the USB interface 36 is connected with the rechargeable battery 32, the design of the USB charging interface is adopted, even if the charger is lost, the charger can be easily charged, and the charger/the computer/the charger/the vehicle-mounted multiple charging modes are faster and more convenient. The control part of the control box 3 realizes all control functions through a plurality of keys arranged on the control box 3. In this embodiment, the outline of the control box 3 is an ellipse, but may be other shapes, and the present application is not limited thereto.

The small control module chip 31 digitizes the voice from the microphone (Mic) through an analog-to-digital converter (ADC) by a digital signal processor, processes and codes the signal by a built-in Digital Signal Processor (DSP), modulates the coded signal, and simulates and transmits the modulated signal to a radio frequency transmitter through an antenna by a digital-to-analog converter (DAC). The radio frequency receiver digitizes the analog signal received by the antenna to an analog-to-digital converter of a Digital Signal Processor (DSP) whose software processes, demodulates and decodes the signal, which is then analog and provided to the microphone by the digital-to-analog converter. Therefore, the key points of the digital interphone are voice coding and decoding and modulation and demodulation. The effective bandwidth of voice is reduced by voice coding (DVSI AMBE +2 is selected for both DPMR and DMR), and the modulator modulates the digital code with compressed bandwidth (4 FSK is selected for both DPMR and DMR). Once analog voice communication is changed into digital code (or symbol) communication, channel coding, Forward Error correction (FEC-Forward Error correction) coding is necessary to reduce the Error rate, which results in a digital communication protocol. One benefit of voice digitization is the privacy of the communication and the added signaling. Furthermore, with the addition of more stringent security algorithms (e.g., 128-bit encryption), voice or data communications can be made absolute (theoretically solvable and practically non-solvable-with limited computing power for a limited amount of time). In addition, compared with an analog voice and data system, the digital communication can provide better data processing and interface functions, the duplex change is more reliable and easier to realize, effective data networking can be performed, and voice and data services are more perfect and more convenient.

The tip of function connecting wire 2 be connected with power supply unit 4, the neck formula earplug intercom of hanging a neck of this application can supply power through power supply unit 4, the overlength standby can accomplish to last the standby. The power can be supplied by the rechargeable battery 32 in the control box 2, and the battery can be charged in a USB mode, so that the use is convenient, and in the embodiment, the capacity of the battery in the power supply 4 is 800-1200 mAh.

The neck-hung type earplug interphone is light, is a practical earplug in a factory workshop, is a two-way mobile communication tool, can be used for conversation without any network support, does not generate telephone charge, and is suitable for relatively fixed occasions with frequent conversation. To the workshop, relatively original earplug, megaphone uses and has the limitation, and the intention of oneself is known to the big place of decibel, hardly accomplishes to fall the sound and can let the other side, and the noise control is accomplished to neck formula earplug intercom of hanging the neck, but also can be clear through talkbacking the required information of transmission.

The neck-hung type earplug interphone has the functions that:

1. noise reduction type earplug

Under the environment with large noise, the noise-proof effect can be achieved;

2. real-time intercom

One-to-one, one-to-many and many-to-many communication can be carried out, the tone quality is clear, the voice transmission is fast, and no delay exists;

3. dormancy button (TOANY-8000 unique function)

If you do not want to receive the called party, you can press the sleep key to reject to receive any voice, and if you want to receive the called party again, you can press the key;

4. 6-level volume adjustment

The volume can be adjusted by 6 levels, and the appropriate volume can be selected at will.
