Constructive disposition introduced in speaker.

摘要

"Constructive disposition introduced in speaker". The utility model relates to a new constructive disposition introduced in loudspeaker which is equipped with means of illumination.The speaker includes a circular gasket (1) and a suspension (2) connected to the diaphragm (3). A ring (4) with lamps of the type LED (5) is positioned behind the diaphragm (3).The cap (6) and the diaphragm (3) are implemented in a translucent material, in this way, the consumer can view even the components arranged behind the diaphragm.It integrates the speaker housing (7), in whose center is a magnet (8), coated with a layer (9).Optionally, the speaker may have a protection circuit and variation in the intensity of the light emitted by the LEDs, which allows, according to the rhythm of the music which is being reproduced.The LEDs can emit more or less light intensity.In the ring (4) are mounted to the units of LEDs (LED1 to 12)Which in turn are connected individually in series with a resistor (R3 to R14) which has the function of limiting the electric current through the LEDs.At the entrance of the circuit has a protection circuit formed by a diode rectifier (D1).Which allows the application of alternating current (music signal) which in turn is rectified in a half wave.After you have a zener diode (D4) is connected in series with a resistor (R2) which limits the current of the same.The zener diode (D4), in turn, limits the maximum voltage allowed in the circuit, which exceeded drives the transistor (Q1) through its base, eliminating the excessive tension in the resistor (R1).This circuit makes it possible to use alternating current (music signal) or into direct current and ensures the integrity of the system when used with voltage peaks above the specified.
