Description

  The present invention relates to a light-emitting speaker unit structure, and more particularly to an improved structure implemented for a speaker unit in a sound box.

  As quality of life improves, humans are increasingly focusing on the hobbies of life. Among them, playing an important role is to enjoy hearing, and listening to various kinds of music can appropriately reduce the stress of modern humans. For this reason, in the market, speakers in different fields used for various different applications have been developed. When generally speaking, the basic configuration of a conventional speaker alone is, as shown in FIG. A support frame 71, a vibration diaphragm 69, and a diaphragm board 82, in which an enlarged opening 73 is formed at the front end of the support frame 71, and a magnetic end is formed at the rear end. A member 75 and a sound ring 77 are provided, a vibration diaphragm 79 covers the sound ring 77, and a diaphragm board 81 is provided in the enlarged opening 73, and an inner peripheral edge thereof and the sound ring 77 are provided. Stick to each other and the sound frequency signal enters the sound ring 77 about the utterance principle of the speaker. Later, the sound ring 77 is moved back and forth in the magnetic member 75, thereby interlocking so as to produce a vibration in the vibration diaphragm 79 and the diaphragm 81, thereby causing the effect of the waves.

  However, while a typical speaker has an auditory effect, its appearance does not produce a visual effect and cannot receive the consumer's attention. Regarding the demand for the visual effect of the consumer, the change of the lamp / light is the most noticeable. Among light-emitting elements, a thing that has received attention in recent years is an article called electroluminescence (EL), which has many excellent points, a phenomenon that performs conversion of electric energy into light. It is. However, since it does not generate heat during the conversion process, it is called "cold light", and the article is light, luminous, uniform in light emission, highly flexible, can be made into various shapes, and does not generate heat. It has many advantages such as no ultraviolet rays, low power consumption, prevention of vibration and moisture, and endurance of stress.

  As for the sound curve of the speaker, as shown in FIG. 2A, the work frequency is approximately between 50 Hz and 20 KHz, and the range of 1.2 KHz to 1.4 KHz is the most sensitive zone of human hearing. Therefore, the frequency resonance curve of the speaker is generally concentrated in such a range. Also, as shown in FIG. 2B, the sound curve of electroluminescence can obtain excellent brightness at a frequency of about 1 KHz, and as can be understood from these descriptions, the sound frequency signal exerts electroluminescence. However, there is no existing speaker structure that uses a combination of a speaker and electroluminescence.
