 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIG. 1, an inflatable doll (10) has a body (11) made of fabric material, an inflator (12), at least one light stream (13) and a light show controller (20).

An air inlet is defined in a bottom of the body (11) and connected to a vent of the inflator (12). Therefore, when the air inflator (12) is operating, air is supplied to inside of the body (11) through the air inlet. In FIG. 1, the inflator (12) is set up outside of the body (11) and electronically connected to the light show controller (20). The inflator (12) is also set up inside of the body (11).

In FIG. 1, four light streams (13) are mounted inside of the body (11). Each light stream (11) is consisted of multiple light sources connected in serial. The four light streams (11) are electronically connected to the light show controller (20).

With further reference to FIGS. 2A to 2H, the light show controller (20) has a processor (21) having inner memory, at least one electronic switch (22), an input device (23), an audio player (24), and a power converter (25).

In FIGS. 2A to 2H, there are eight electronic switches (22), each of which is connected to the four light streams (13) connected in parallel. A trigger terminal of each electronic switch (22) is connected to output terminal of the processor (21) through a resistor (R1 to R8) and a data bus (IC1BUS). Two other terminals of the each electronic switch are respectively connected to corresponding light stream or the light streams (13) and ground. When a trigger voltage inputs to the trigger terminal of the electronic switch (22), two terminals are electronically connected together. That is, the light streams (13) are electronically and commonly connected to the ground to light. Therefore, the light show controller (20) has eight output terminals. The electronic switch (22) is a Triode AC Switch (hereafter TRIAC). The trigger terminal of the TRIAC is gate terminal and the other terminals are respectively anode and cathode terminals.

The input device (23) includes a switch element (SW1) with four sub-switches that are respectively connected to corresponding input terminal (P10 to P13) of the processor (21). The input device (23) further has an audio-controlling unit having a buzzer (BZ) and a signal converter (231). The signal converter (231) is connected between output of the buzzer (BZ) and another input terminal (P20) of the processor (21). A user can uses the switch element (SW1) to select different light show.

The audio player (24) has an audio driver (241) and a speaker (SPK). The audio driver (241) is electronically connected between another output terminal (V01A) of the processor (21) and the speaker (SPK). The processor (21) outputs audio signal to the speaker (SPK) through the audio driver (241), so the speaker (SPK) outputs the audio signal to the people.

The power converter (25) has an AC to DC adapter (251) and a voltage regulator (252). The AC to DC adapter (251) is connected to an external AC power (120V/60 Hz) and then converts the AC power to a first DC power (DC 12V). The voltage regulator (252) is connected to the AC to DC adapter to further convert the DC power from the AC to DC adapter to a second DC power (DC 5V). The first DC power is supplied to the audio player (24) and the second DC power is supplied to the other electronic units, such as the processor (21) and input device (23). The light streams (13) and the inflator (12) are connected to the external AC power through a fuse (F1).

The processor (21) builds a controlling procedure, music signal and a table. With further reference to FIG. 3, the controlling procedure has four light show modes corresponding to the four sub-switches of the switch element (SW1).

In a first light show mode (M1), the processor (21) detects voltage level changes to determine whether any high decibel audio is received by the buzzer (BZ), and drives all light streams (13) to light through the electronic switches (22), when the determining result of the processor is positive. However, in the first mode, the processor (21) does not output the music signal to the speaker (SPK) through the audio driver (241). Therefore, when the user switches the switch element (SW1) to the first sub-switch, the light streams (13) inside of the body (11) will light when the buzzer (BZ) receives high decibel audio signal. On the contrary, if the buzzer (BZ) does not receive the high decibel audio signal, the light stream (13) inside of the body (11) will not light.

When the user switches the switch element (SW1) to the second sub-switch, the processor (21) executes a second light show mode (M2). The processor (21) only drives the light streams (13) to light through the electronic switches (22) and does not drive the speaker (SPK).

When the user switches the switch element (SW1) to the third sub-switch, the processor executes a third light show mode (M3). The processor (21) only drives the light streams (13) through the electronic switches (22) to glitter according to a fixed cycle order. That is, the processor (21) alternatively outputs high and low voltages to the trigger terminals of the electronic switches (22).

In a fourth light show mode (M4), the processor (21) drivers the light streams to glitter according to music in current playing status. With further reference to FIG. 4 A, one music signal is marked by different symbols (S1 to S3) and the music signal with symbols (S1 to S3) are stored in the inner memory. FIG. 4B shows one example of the table having multiple symbols (S1 to S3) and driving statuses for light streams. The multiple symbols (T1 to T3) respectively correspond to different driving status of the electronic switch(es). For example, the processor (21) drives the electronic switches to glitter quickly according to the first driving status when the processor (21) determines that the present symbol in current music signal is first symbol (S1). Therefore, when the processor (21) plays the music signal, the processor (21) drives the corresponding light streams through the electronic switch (22) according to the symbols of the music signal.

With reference to FIG. 5, the controlling procedure of the processor has steps of:

(a) detecting which sub-switch is switched? (30)

(b) if the first sub-switch is switched, the first mode executed and the light streams driven to glitter according to decibel changes of outside audio of the body; (31)

(c) if the second sub-switch is switched, the second mode executed and the light streams driven to light; (32)

(d) if the third sub-switch is switched, the third mode executed and the light streams are driven to glitter according to different symbols of the current playing music; (33) and

(e) if the four sub-switch is switched, the fourth mode executed and the light streams are driven to glitter according to the fixed cycle order (34).

Based on the forgoing description, the present invention makes the inflatable doll with the light streams to have different light shows. Therefore, the inflatable doll with the light show controller in accordance with the present invention provides various light shows to catch more sights of the people.

Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only.
