In the case of existing products, when a single sound device is connected, there is a case where you cannot hear the sound of other communication devices, and you cannot hear the prompt notification sound or sound signal generated by the communication device as needed, whereas the present invention The multi-channel sound signal that can be controlled through allows you to listen to the sound signals of various devices at the same time, so it can be used as equipment that increases work efficiency and secures safety during movement and safety at industrial sites.

Description

Multi-channel wireless sound system allowing multi-channel entry {Multi-channel wireless sound system}

The present invention relates to a multi-channel wireless sound system, and more particularly, as an operating method for an earphone or speaker system transmitted and received using commonly used Bluetooth (or wireless technology such as wifi), such as a mobile phone, tablet PC, and laptop computer. It is a method for a technology that implements sound by simultaneously connecting multiple mobile devices such as

In general, sound devices (earphones, speakers, etc.) using wireless communication are used in many places. In the process of using various personal mobile devices, there are many cases in which multiple mobile devices are used. However, since sound devices using wireless communication are symmetrically connected to mobile devices, This causes inconvenience to the use of the system.

In particular, in the case of sales workers, there are cases where two or more cell phones are used, and it can be quite inconvenient to have a wireless communication earphone system for every cell phone, and if the earphone system is not provided, it may cause danger in situations such as driving a vehicle. there is.

As a conventional method, if there are two mobile devices capable of wireless communication between A and B, there is a method of disconnecting the audio device connected to A and then reconnecting to B, but the procedure is inconvenient, driving or walking It can be dangerous when moving the back, so it can be determined that there may be a demand for wireless communication acoustic devices that can be easily connected to multiple channels to meet the user's needs.

Therefore, the proposed present invention is composed of an input unit, a processing unit, and a transmission/reception unit, and the input unit is responsible for wireless connection of a plurality of mobile devices. The purpose of the department named processing unit is to adjust the volume of each incoming mobile device and to operate a technically feasible combination of sounds. The transmitting/receiving unit is divided into a transmitting unit and a receiving unit, and the transmitting unit is composed of a microphone, and the receiving unit is composed of a speaker or an earphone, so it is possible to operate a sound system suitable for the purpose of communication, music appreciation, etc.

An object of the present invention is to connect sound systems of various mobile devices into one sound system.

The processing unit must be able to control the input sound

In the transceiver unit, the sound of various devices can be heard at the same time, and some sounds must be blocked according to the user's choice.

For multi-channel input of the input unit, it is possible to approve the entry of sound signals by overlapping the wireless communication module of the international standard currently in use. The number of input channels for each device can be flexibly changed according to the user or development purpose.

The processing unit is programmed so that it can be controlled and managed with a computer or mobile application.

The transceiver must be able to clearly hear or transmit the sound set through the program of the processing unit, and it must be configured using a microphone and speaker module.

In the work structure of modern society using smartphones, laptops, tablet PCs and many other devices, sound systems are used for notification of various messages, phone calls, and listening to music. The multi-channel wireless sound system developed through the present invention, allowing multi-channel input, can control the sound of facilities requiring multiple sound connections with one device, so it is economical because it does not need to use a plurality of sound devices, and operation and can actively respond to safety accidents that may occur during movement such as walking.

Since the application category in each industrial site is high, there is an effect of increasing industriality and stability in various environments.

The representative drawing is a basic structural diagram of a multi-channel wireless acoustic system.
101. The communication device unit refers to communication devices that transmit sound signals from various communication devices, and consists of wireless communication devices such as personal smartphones, business smartphones, tablet PCs, laptops, radios, and other communication devices that are widely used.
201. The input unit is a communication module that transmits and receives transmission signals of variously configured communication devices, and allows communication modules assigned a unique serial number to be connected to each communication device.
301. The processing unit combines the sound signal of the microphone generated through the communication device connected through the input unit and the transmitter/receiver unit, so that functions such as volume control, MUTE function, and EQ can be implemented.
401. The transmitting/receiving unit is composed of a microphone and a speaker, and may support a multi-channel microphone or a multi-channel speaker depending on circumstances. The sound signal collected through the microphone is transmitted to the processing unit and transmitted to the designated communication device, and the sound signal processed through the input unit is transmitted through the speaker. (Microphones and speakers of the transmitter and receiver expressed in section 401 are operated in a category that covers other sound systems such as earphone systems.)

The multi-channel wireless sound system of the present invention is to create a sound system that connects a communication device 101 composed of a mobile phone or smart phone, tablet PC, laptop or computer, radio, and other sound devices used in the market through multi-channels. It is aimed at and is composed of an input unit 201, a processing unit 301, and a transmission/reception unit 401.

In the case of transmission of a sound signal, various devices of the communication device 101 are connected to the multi-channel input unit 201 to which each unique number is assigned (e.g., 201-1, 201-2, 20. The channels of ..201-x) are connected and sent to the processor 301, and the sound signal generated through the processor 301 is transmitted to the transceiver 401 to transmit the combined sound.

In the case of receiving a sound signal, the sound signal collected through the microphone of the transceiver 401 is sent to the processing unit 301 and connected to the communication device 101 via the input unit 201.

Effects expected through the present invention are as follows.

1) By allowing users who use multiple communication devices to use one wireless earphone system, eliminating the hassle of connecting wireless earphones for each communication device, supporting a safe movement method when moving

2) Mobile phones, radios capable of wireless communication, and other communication devices at industrial sites can be operated as a single sound system, enabling safe industrial sites to be operated.

3) It can be used where other multi-channel sound systems are needed, and sound systems are expected to be applied and utilized in various industrial fields, considering that they are already used in daily life with a high level of frequency.
