Description

Loudspeaker positioning control system and method

The present invention relates to a speaker positioning control system and method, and more particularly to a speaker positioning control system and method that can set a specific fixed point of the speaker by providing a notification signal for the speakers to receive, thereby enabling the speaker at the specific fixed point to perform the set function, thereby easily obtaining the best surround sound field effect.

With the advancement of technology and economic development, people's requirements for quality of life are getting higher and higher. As for audio equipment, traditional stereo audio can no longer meet the needs of consumers. Therefore, 5.1 multi-channel audio with good sound effects is favored by the majority of consumers. As we all know, "surround sound" is a system used in audio engineering to make multiple channels and speakers provide a sound reproduction system for a listener located between the speakers. The sound can be reproduced through multiple speakers with different delays and different intensities to "surround" the listener with the sound source, thereby producing a realistic listening effect.

However, "surround sound" refers to the use of speakers positioned around a listener to reproduce the sound of an audio signal containing multiple channels. For example, 5.1 surround sound uses at least front, center, rear, and even a subwoofer speakers. Therefore, when the audio signal is output to speakers at different locations, the multi-channel audio signal can provide the listener with a sense of space in the sound field.

It is not difficult to place a speaker in an environment; however, when you want to place multiple speakers in an environment, the problem of how to place the speakers correctly arises. Although the speakers used in general "surround sound" are set in different shapes for the front, center, rear, and subwoofer, they usually still need to be arranged appropriately by professional technicians in accordance with the space, which is difficult to construct. And after each move, the speaker must be returned to the predetermined placement to confirm whether the best effect is achieved before the best sound quality can be brought into play. Therefore, the speakers used in general "surround sound" actually cause great trouble to consumers. If all speakers are set to be full-range speakers of the same shape, the problem of matching them with the space can be solved. However, how to set the same speakers to produce different sound effects in different locations is actually a major issue for the industry.

In view of this, the applicant, after continuous research and experiments, came up with the idea of designing a speaker positioning control system and method, which sets a specific point of the speaker by a notification signal, so that the speaker at the specific point performs the set function, thereby easily obtaining the best surround sound field effect.

The main purpose of the present invention is to provide a speaker positioning control system and method, which broadcasts a notification signal through an electronic communication device for the speakers to receive, so as to set the specific fixed point of the speaker, and then make the speaker at the specific fixed point perform the set function, so as to simply obtain the best surround sound field effect and make the positioning of multi-channel speakers more convenient.

The aforementioned speaker positioning control method includes: placing a plurality of speakers in a mesh network environment; broadcasting a notification signal by an electronic device; receiving the notification signal by the speaker and determining the location of the electronic communication device; and setting a specific fixed point of the speaker based on the relative specific position of the speaker and the electronic communication device, so that the speaker at the specific fixed point performs the set function.

The aforementioned speaker positioning control system includes a plurality of speakers placed in a mesh network environment and at least one electronic communication device that can be connected to the speakers. The speakers at least include modules such as audio signals, network transmission and authorization lists, and memory; and the electronic communication device at least includes a speaker configuration application.

In the aforementioned speaker positioning control system, the networking transmission modules of the speakers are connected to the electronic communication device in a wireless Bluetooth transmission mode.

In the aforementioned speaker positioning control system, the authorization list is used to compile the identification codes of the connected electronic communication devices and is stored in the memory module.

The aforementioned speaker positioning control system, wherein the electronic communication device can be a smart phone or an I-pad, etc., with the help of the directional enhancement function in Bluetooth 5.1, this technology can provide a positioning function similar to GPS when working indoors.

Please refer to FIG. 1 and FIG. 2, which are the system architecture diagram and block diagram of the present invention. As shown in the figure, it is an embodiment of an ambient sound system. In the embodiment, the present invention includes a plurality of speakers 1a, 1b, 1c, 1d, 1e, 1f, 1g placed in a mesh network environment, and at least one electronic communication device 2 that can be connected to the speakers 1a~1g. Among them, the speakers 1a~1g at least include a microprocessor module 11, and an audio signal module 12, a network transmission module 13, an authorization list module 14, a memory module 15 and other modules electrically connected to the microprocessor module 11.

The network transmission module 13 is provided for connection with the electronic communication device 2, and it is a wireless Bluetooth transmission mode.

The authorization list module 14 is used to compile the identification codes of the connected electronic communication devices 2.

The memory module 15 is used to store the identification code of the electronic communication device 2 to which the authorization list module 14 has been connected.

The aforementioned plurality of speakers 1a~1g, in the embodiment of the present invention, are configured to include at least a left front speaker 1a (FL), a right front speaker 1b (FR), a center speaker 1c (CNT), a left rear speaker 1d (SL), a right rear speaker 1e (RL) and a subwoofer 1f (SW). The speakers 1a~1e are five 3-20,000Hz full-range speakers; and a 3-120Hz subwoofer 1f.

The electronic communication device 2 at least includes a speaker configuration application (APP) 21. In this embodiment, the electronic communication device 2 can be a smart phone or an I-pad, etc. With the help of the directional enhancement function in Bluetooth 5.1, this technology can provide a positioning function similar to GPS when working indoors.

By combining the above components, a speaker positioning control system is formed. When the user wants to place a plurality of speakers 1a-1e at appropriate positions to obtain the best surround sound field, the speaker configuration application 21 loaded in the electronic communication device 2 can be activated to broadcast a notification signal (Beacon signal) for the speakers 1a-1e to receive, so that the speakers 1a-1e can determine the position range of the electronic communication device 2 according to the notification signal, thereby calculating the position of the speakers 1a-1e and the electronic communication device 2. The relative specific position of the electronic communication device 2 allows the microprocessor module 11 to send a control signal to set the specific fixed point of the speaker 1a~1e (left, right front or left, right rear or center), and then the audio signal module 12 receives audio signals such as sound and music, so that the speakers 1a~1e at the specific fixed point execute the set left and right front or left and right rear or center response functions, so as to simply obtain the best surround sound field effect.
