Abstract

(57) [abstract] (with correction) [Problem] Only a small-diameter speaker can be used because it is necessary to incorporate a voice chip, an amplifier, a speaker, and a power supply into the gun toy. The hole for extracting the sound of the paper part to the outside impairs the real feeling of appearance. SOLUTION: The output of an audio chip 4 of a bullet shooting sound provided inside a gun toy 1 is transmitted by FM radio waves, and the radio waves are received by a sound quality-oriented FM stereo receiver equipped with a large speaker placed nearby. . A sound chip 4 for bullet shooting sound provided inside the gun toy 1 samples a digital recording from an actual bullet shooting sound and masks ROM in the sound chip 4.
Create The operation of the trigger 2 signal terminal can be reduced to a single sound source by using a retriggerable type, and all circuits can be accommodated in a limited space. The FM radio wave transmission circuit 5 only needs to transmit a radio wave to a receiver placed in the immediate vicinity of the gun toy.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 An FM radio wave modulated by the sound of a bullet fired from a gun toy is transmitted in conjunction with the trigger operation of the gun toy, so that it can be received and heard on a vacant frequency of a nearby FM radio receiver. Gun toys.

[0002]

[Prior art]

 There has been a sound toy for listening to gun firing sounds, an amplifier, and a small speaker built into a gun toy.

[0003]

[Problems to be solved by the invention]

 Since the sound chip, amplifier, speaker, and power supply all need to be incorporated into the gun toy, only small-diameter speakers can be used, resulting in a lack of realism of the sound.At the same time, holes for extracting the sound of the speaker cone paper to the outside However, there is a need to solve problems such as impairing the real appearance.

[0004]

[Means for Solving the Problems]

 A small-diameter speaker that can be installed inside a gun toy and a limited narrow internal space cannot generate realistic bullet shooting sound.Therefore, an amplifier and speaker should be installed inside the gun toy. Stop and transmit the sound chip output of the bullet shooting sound provided inside by FM radio wave, and if this radio wave is received by a sound quality-oriented FM stereo receiver equipped with a large speaker placed nearby, the receiver will be prepared. The audio reproduction frequency band can also be corrected with a graphic equalizer, so that the sound from the gun can be reproduced more realistically and headphones can be used.

[0005]

[Embodiment of the invention]

 The sound chip for bullet shooting sound provided inside the gun toy samples the digital recording from the actual shooting sound and creates a mask ROM in the sound chip. The operation of the trigger signal terminal is a retriggerable type, so that only one sound source can be used, and all circuits can be stored in a limited space. The FM radio wave transmission circuit only needs to transmit radio waves to the receiver placed in the immediate vicinity of the gun toy, so it is sufficient to output a weak radio wave. The battery for the power supply is a 3V lithium coin battery, including the operating current of the aforementioned voice chip. One can operate. Since the appearance must be as realistic as possible and the power ON / OFF switch is omitted to simplify the operation, the power is turned on at the first trigger operation of the gun toy and the trigger operation time interval is continuous within 3 minutes. During this time, the power supply was kept on, and the power supply was automatically turned off when the trigger operation was suspended for more than 3 minutes.

【Example】

 One embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of the functions required for the present invention provided inside the toy 1. The bullet firing mechanism of the toy is omitted from the present invention because it is unnecessary to explain. By operating the trigger 2 of the gun toy, the trigger contact 3 is actuated in contact, and the gun sound signal from the sound chip 4 for bullet sound emission is added to the modulation signal input circuit of the FM radio wave transmission circuit 5 and modulated by the transmission sound from the transmission antenna 8. The transmitted weak FM radio wave is transmitted at the same timing as the trigger operation. Guns A sound chip for shooting sound 4 containing several different gun sounds can be used to provide a select switch to change the firing sound, or a different gun sound can be randomly generated by each trigger operation. It is also possible to put out. The automatic power ON / OFF circuit 6, which operates in conjunction with the trigger operation, utilizes the threshold value of the C-MOS inverter buffer 13 and the charge / discharge of the capacitor. Since the power supply voltage is always charged to the capacitor 12 by the resistor 11 and exceeds the threshold value of 13, the output terminal 13 is at the L level and no voltage is applied to the power supply regulator IC 16 and the FM radio wave transmission circuit 5 Since there is no power supply and radio waves are in a stopped state, the power supply regulator with the voltage supply stopped together with the bullet firing sound audio chip circuit 4 through which almost no current flows except during operation does not consume current, so lithium is not used. Battery 7 is not consumed and the power supply is kept off. Next, when the trigger contact 3 is actuated for the first time, the charge stored in the capacitor 12 is instantaneously discharged by the diode 14 connected to this contact, and the input part 13 goes from the H level to the L level and is output at the same time. Since the power terminal goes to the H level, the power supply voltage is applied to the power supply regulator IC 16, and when the power is supplied from the output supply line 9, the FM radio wave transmission circuit 5 also starts operating instantaneously and transmits a gunshot sound. While the triggering operation is continuous, the charge of the capacitor 12 is constantly discharged, so that the input section 13 keeps the L level and the output section keeps the H level, so that the power ON state is maintained. After a pause of 3 minutes or more, the power is automatically turned off at the timing determined by the resistor 11 and the capacitor 12 to save battery consumption. For the reception of FM radio waves modulated by gunshot sounds, the transmission frequency must be adjusted in order to select and use a vacant frequency that is not broadcast in the general FM radio frequency band. This is performed by turning the core of the transmission frequency adjusting coil 15. The circuit 10 of the trigger contact 3 may be operated by a switch circuit means other than the trigger operation, and a sensor or the like may be used.

[Effect of the invention]

 As described above, the present invention makes it possible to enjoy a gun toy without having to fire a bullet from the gun toy while compensating for the lack of realism of the conventional gun toy. Is provided.
