Description

A horn that can produce flashing effects with the melody of the music

technical field

The utility model relates to a loudspeaker, in particular to a loudspeaker capable of producing flashing effects along with the melody of music.

Background technique

Ordinary horns are only for sound output, completely for auditory experience, such as an [air horn with sound and light effect], which mainly includes the main body of the horn, the drum box, the tympanic membrane, the cover plate, the air intake The lamp holder, light bulb, lampshade and other components combined with an air connector and a light indicator are characterized in that: a lamp holder body is connected to a connecting block on the outside of the horn tube body close to the bell mouth, so that the combined bulb, light collecting plate and lampshade etc., and connect the wires to the junction box for control, and connect the horn pneumatically in series, and operate synchronously, so that when the horn is honked, a light signal is displayed on the outside at the same time, making it more eye-catching and attractive to distinguish.

However, the above-mentioned structure, although the light signal will be displayed synchronously when the horn is sounded, or the switch can be selected to display the sound and light separately during operation and use, further increasing the visual experience, but the light signal only follows the horn. A single press will turn on and off, and the visual experience is more monotonous and ordinary, and there is no novel effect that can be displayed creatively on and off with the change of the music rotation rate, so it is still not ideal.

Contents of the invention

Therefore, how to improve the existing shortcomings of the above-mentioned publicly used known structure, and provide a speaker that can produce a flash effect with the melody of the music, and adjust the light of the light-emitting part by the frequency of the music through the audio control circuit to cooperate with the music playback The number changes, so that it produces special visual effects, and can enjoy music at the same time, which is the purpose that the utility model wants to achieve.

The technical problem to be solved by the utility model is mainly to propose a horn that can produce a flashing effect with the melody of music in view of the existing shortcomings of the above known structure, especially to change the flashing change of the light-emitting part by the frequency of the sound.

The technical problem of the utility model is solved by the following technical solutions.

A loudspeaker capable of producing flashing effects along with the melody of music is characterized in that: a light-emitting element and an audio control circuit are arranged on the loudspeaker, the input of the audio control circuit is connected to the loudspeaker in parallel, and the output of the audio control circuit is connected to the light-emitting element. The luminous element is controlled by the audio control circuit to flicker and change with the change of the input music frequency.

In addition to the above-mentioned necessary technical features, the following technical content can also be added during the specific implementation process: the luminous element is a luminescent sheet.

The audio frequency control circuit is composed of a chip and a plurality of resistors, capacitors, diodes and transistors.

The luminous part is arranged on the dustproof cover of the speaker unit.

The luminous element is arranged on the suspension edge of the speaker unit.

The luminous part is arranged at the vicinity of the loudspeaker-attached sound box.

The utility model has the advantages of:

The utility model is provided with a light-emitting part and an audio control circuit at the right place of the speaker. The light-emitting part is controlled by the audio control circuit; the flickering change of the light-emitting part is controlled by the change of the frequency of the music input. You can enjoy the light signals that change with the rhythm of the music, which has dual visual and auditory enjoyment.

The novelty and other features of the present utility model will become clearer with the detailed description of the following accompanying drawings.

Detailed ways

Please refer to Fig. 1, the utility model is mainly combined with a speaker 10 outside the general sound box 1, and a light-emitting part 20 can be selectively attached to the speaker body or a nearby sound box, and an audio control circuit 30 is combined inside it; Wherein, the light-emitting element 20 can be a luminescent sheet, and an electrode 21 is extended from the luminescent sheet for connecting with the audio control circuit 30 .

As shown in Figure 2, the speaker 10 casing of the sound box 1 is connected to one end of the vibrating basin 13 by the hanging edge 15, and the other end of the vibrating basin 13 is connected with the voice coil 11, and the upper end of the voice coil 11 is connected with a The elastic wave 12 is connected with the shell of the speaker 10. At the same time, a dustproof cover 14 is arranged on the voice coil 11. Because the cold light sheet is a kind of very thin plane material, it can be made into any plane shape and size, even soft enough to be Easy to analyze, in this preferred embodiment, the luminous element 20 is cut to be slightly larger than the dustproof cover 14, and the luminous element 20 is flatly pasted on the dustproof cover 14, and the electrodes 21 of the luminous element 20 extend to The shell of the speaker 10 is also connected with the audio control circuit 30. Because the basic structure of the cold light sheet is a sandwich structure, an inorganic phosphor is sandwiched between the two electrodes. In order to make the emitted light visible, one side must be a transparent electrode (generally It uses indium stannate (Indium Tin Oxide) (ITO for short). When the luminescent element is biased, the holes and electrons start from the positive and negative electrodes and cross their respective barriers, and then meet and recombine in the organic material layer to emit light.

Please refer to Figures 3 and 4, which are the audio control circuit 30 of the present invention. The audio control circuit 30 is a commonly used voice control circuit, such as lighting control for dance halls. It is mainly based on a chip 31 that can be written in the control program in advance, and is composed of a plurality of transistors, resistors, capacitors and diodes. When the power is turned on, the speaker signal sensing circuit 32 composed of diodes and resistors, Receiving the sound signal output by the speaker 1, the sound signal is converted by the chip 31 to change the operating voltage and frequency of the load (the light-emitting element 20), so that the light-emitting effect of the light-emitting element 20 will not continue to be monotonously on or off effect, but can vary with the frequency of the music.

As shown in Figure 5, when the audio main unit is turned on, the speaker 1 will play the sound, and the sound signal will be converted by the audio control circuit at the same time, so that the light-emitting element 20 installed on the outside of the dust cover 14 can be With the different intensities of the music, the change of its own light signal changes, so that in addition to enjoying the music, there is also the cooperation of flashing lights, adding different visual and auditory experiences.

As shown in FIG. 6, the luminous element 22 can also directly replace the function of the dust-proof cover, and be installed outside the dust-proof cover 14 and fill in the overhanging edge 15 thereof. At the same time, based on the idea of this utility model, the light-emitting element can also be installed at other adjacent positions of the sound box 1, such as the sound box frame or the sound box surface, and the like.

To sum up, the speaker of the present utility model that can produce a flashing effect with the melody of the music controls the flashing effect of the luminous parts with the sound pressure, and can also watch and change the light signal in accordance with the rhythm while enjoying the music. As far as the overall space type is concerned, it is an innovation, and the improvement in efficacy is obvious, and a new patent application is filed according to law.

However, the above description is only a preferred embodiment of the present utility model, and should not limit the scope of implementation of the present utility model, that is, all equivalent changes and modifications made according to the patent scope of the utility model should still belong to this utility model. within the scope of utility model patents.
