Problems solved by technology

Moreover, it can be seen from its manual that when there are multiple infrared transmitting and receiving devices with signal feedback, it is regarded as invalid data, which is difficult to avoid in daily operation, resulting in the inconvenience of electrical operation
[0006] Another fatal flaw of the above two technologies is that the sensor works continuously, which brings high power consumption on the one hand, and greatly shortens the life of the infrared emitter on the other hand.
As for the speaker's life expectancy of at least two or three years, as many as six or seven years, it is obviously impossible to use the existing traditional technology to achieve non-contact induction control.
A product that is expensive, inconvenient to use, and has an extremely short lifespan obviously cannot be recognized by consumers, which is why infrared sensing technology has been developed for more than ten years to realize non-contact sensing control and cannot be widely used.

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] Such as figure 1 The non-contact induction control system for a sound box includes: five infrared modules 41, 42, 43, 44 and 45 with infrared transmitters and receivers, wherein the infrared modules 43 and 44 are used to control the volume increase and decrease , Infrared modules 41, 42 are used to control the last and next song of music, and infrared module 45 is used to control music playback / stop and continue / pause (starting / standby). combine figure 2 In the structural diagram of the sound box shown, the infrared module 45 is arranged on the front of the sound box, the infrared modules 41 and 42 are arranged on the left and right sides of the sound box, and the infrared modules 43 and 44 are arranged on both sides of the top of the sound box.

[0034] The above-mentioned infrared module controls the emission law of its infrared signal through an infrared s...

Abstract

The invention relates to the technical field of sound box control, solves the technical problem of overcoming the defect of the prior art, and provides a sound box non-contact inductive control system, which has no interference, long service life and low requirement on data band width, and a control method thereof for the current infrared inductive technology. The control method adopted by the invention is that different control functions of the sound box is realized by using a plurality of infrared modules in a non-contact manner; infrared signals are circularly transmitted between the multiple infrared modules; and when one of the modules receives a feedback signal, the infrared module is locked to transmit infrared signals continuously, and sound box function control can be realized according to the control function corresponding to the infrared module. The invention has the advantages that the number of the infrared modules is absolutely not limited, and the installation positions are also not limited, thus a huge design space is brought to designers of sound box industry to lead the products to be more diversified.

Description

technical field [0001] The invention relates to the technical field of sound box control, in particular to a sound box non-contact induction control system and a control method thereof. Background technique [0002] The realization of non-contact induction control through infrared induction technology is a new control technology in electrical appliances, and also represents a trend of electrical appliance control in the future. Carrying out the volume control of sound box by this technology is also a kind of common technology, as patent No. 02248331.4, the name is called "non-contact induction volume adjustment device" and application number is 200910105086.3, the name is "use infrared induction to control TV channel and Volume system", in these published background technologies, it has been described in detail how to use the infrared sensing technology to realize the control of the volume of the sound box. [0003] However, this technology, which has been developed for nea...
