Embodiment 1

[0030] refer to figure 1 . In the preferred embodiment described below, the system model of a push-to-talk intercom with multiple Bluetooth links to mobile terminals mainly includes Bluetooth device 1, Bluetooth device 2 and a power supply module that can simultaneously link mobile terminals. The bluetooth device 2 is provided with a push-to-talk PTT button electrically connected to the bluetooth module 2 through the I / O port, and an audio output module 2 connected to the interface 2; the audio output module 2 shares power with other devices in the bluetooth device 2; the bluetooth device 1 The audio output module 1 is connected to the Bluetooth module 1 through the switch 1, and the audio input module is directly connected to the Bluetooth module 1. When the bluetooth device 1 is used alone, the conversion switch 1 connects the audio input module 1 and the audio output module 1 to the pulse code modulation PCM interface of the bluetooth module 1 of the bluetooth device 1, th...

Embodiment 2

[0043] refer to figure 2 . exist figure 2 In the shown embodiment, according to Embodiment 1, the audio output modules in the Bluetooth device 1 and the Bluetooth device 2 are connected to the interface and the switch through the power amplifier module, and the volume adjustment key is connected to the peripheral control circuit of the power amplifier module. The volume adjustment key is used to adjust the multiple of the power amplification, which can meet the needs of the user to adjust the volume. Since the trunking intercom terminal needs to face a noisy environment in actual use, the volume is a very important indicator in the application of the trunking intercom terminal. In this embodiment, the bluetooth module and the audio output module are electrically connected to the power amplifier module, and the use of power amplification can increase the audio output power of the audio output module to meet the requirements of cluster intercom with clear volume in noisy env...

Embodiment 3

[0045] refer to image 3 . exist figure 2 In the illustrated embodiment, according to Embodiment 1, a portable PTT Bluetooth device 3 is provided outside the Bluetooth device 1 and the Bluetooth device 2, and both the Bluetooth device 2 and the Bluetooth device 3 are provided with a PTT button that triggers the mobile terminal to initiate a PTT call. The portable PTT bluetooth device 3 and the bluetooth earphone of the bluetooth device 1 can be combined into a portable PTT call mode, without carrying a relatively bulky mobile phone in the traditional mode.

Abstract

The invention discloses a push-to-talk interphone with multiple Bluetooth link mobile terminals and aims to provide a Bluetooth-link PTT intercom which is high in universality, flexible in call mode and independent of PTT long key-pressing of the mobile terminals and has controllable confidentiality. According to the technical scheme, a Bluetooth device 2 is provided with a PTT key and an audio output module 2, and the PTT key and the audio output module 2 are electrically connected through an I / O port; a Bluetooth device 1 is provided with an audio input module 1. When the Bluetooth device 1 is used independently, a Bluetooth module 1 is connected with the audio input module 1 and an audio output module 1 of the Bluetooth device 1; when the Bluetooth device 1 is connected with the Bluetooth device 2 in a plug-in mode, the Bluetooth module 1 is connected with the audio input module 1 of the Bluetooth device 1 and the audio output module 2 of the Bluetooth device 2. According to the push-to-talk interphone with the multiple Bluetooth link mobile terminals, due to the fact that the two Bluetooth devices are adopted, the confidentiality and the hiding property of PTT group talkback through a Bluetooth headset are improved, and the problems that when a customized machine mode is adopted by a talkback terminal, appearance elements are abandoned, PTT keys are large in size, and the mobile terminals are clumsy are solved.

Description

technical field [0001] 1) The present invention relates to a device for triggering the one-key group talk intercom function on multiple Bluetooth devices. Especially involving small and medium-sized enterprises that need frequent contact and individual users who need to chat with friends and family members, including: prisons, medical emergency, flood control, earthquake defense, air defense, fire emergency, public security transportation, urban management law enforcement, taxi, aviation, navigation, high-speed Highways, railways, national security, electric power, petroleum, coal, fire protection, first aid, flood control, forest protection, fire protection, tourism, etc. are linked with mobile terminals and users of trunking communication services based on wireless networks. Background technique [0002] 2) In today's information age, people always hope that they can make a call immediately by pressing a certain key, instead of dialing 11 digits first like public mobile ph...
