While couples and ordinary people use various portable devices (typically mobile phones or smart phones), they often cannot remember where the devices are placed. In this case, if the device is a mobile phone, a call is made to the mobile phone by using a landline phone, and the ring tone of the mobile phone is ringed. However, if the mobile phone is vibrated or if the power of the mobile phone is exhausted, it is difficult to locate the mobile phone. Accordingly, the present invention provides a method (apparatus) that can be easily found regardless of the presence or absence of a mobile phone power source or the presence or absence of vibration of the mobile phone transmission state. According to the present invention, there is a radio transmitter and a receiver, and the receiver needs to use almost the hardware built into the cellular phone, and only the software (computer program) for driving the hardware needs to be installed.

The inventions similar to the present invention differ from the present invention in the following points.

Document 4 is a device attached to a portable device with a tape, which is a device that recognizes voice and exposes its location, and is fundamentally different from the method using a short range wireless generator (mainly Bluetooth) proposed by the present invention. In addition, voice recognition technology is a very difficult technology, it is far from commercialized, and when using voice, the communication range is limited. To send a voice signal far away, it must be loud. In this case, the voice signal is necessarily distorted.

Document 5 is a method for finding a lost mobile phone by short-range communication as in the present patent. What is different from this patent is that the lost cell phone works by itself and uses its built-in GPS to send its location as a text message to other cell phones. The problem is that the lost cell phone must remain powered and work on its own. In other words, it becomes useless without a power supply. Also, a lost cell phone must have GPS. If not, it claims to be roughly located via a base station, but this method is already being serviced by several carriers. In the near field (i.e., when the radio signal passes), it operates by the signal of the radio communication, but uses the method of sending the location as a text message to another mobile phone using GPS, as described above. By sounding "sound" within close range used by the present invention, it is fundamentally different from the easy way of finding.

In Document 6, a method and an objective are fundamentally found as a method of finding the same group by setting and using a specific frequency for each group (a hobbyist or a social group), by setting and using a specific frequency (frequency tuning method). There is a difference.

1 is the whole picture. Typically, when you buy a cell phone, you come with a cell phone and a charger suitable for that cell phone. The charger converts 220V AC power into DC that matches the voltage of the battery, charging the current consumed by the battery. In the present invention, a radio frequency generator and a corresponding receiver play a main role. The radio frequency generator 400 is inserted alone or in a portion of this charger (200 in FIG. 1). In addition, the mobile phone adds a part for detecting the radio frequency ((100) of FIG. 1). When a person who wants to find a lost cellular phone, when the radio frequency generator or the radio frequency generator of the charger alone operates, the cellular phone detects the generated radio signal (300 of FIG. 1) and rings its speaker. In general, a mobile phone has a built-in transmitter and receiver for Bluetooth or ZigBee communication, and a processor (CPU) for processing them. Thus, the receiver for achieving the present invention costs little extra.

You can easily find your cell phone. That is, the charger is always in a fixed position (always connected to a wall outlet using a plug). That is, using this charger, the user can easily find the mobile phone within a certain distance from the charger wherever the user places the phone. In addition, in case a mobile phone is lost from the outside, when a wireless generator (small size) is always accompanied by a bag, the mobile phone can be used to find a lost mobile phone in a limited area outside.

A schematic illustration of FIG. 1. That is, a picture of a mobile phone or mobile device and a charger (radio frequency generator attached to a charger) or a radio frequency generator communicating with each other. In this figure, 300 represents wireless.
2 is a view of the inside of the charger and the mobile phone or mobile device. The radio frequency generator is mounted alone or inside the charger. This figure shows only the picture mounted inside the charger.
Figure 3 shows the radio frequency generator fits on the instrument of the charger.

It demonstrates based on FIG. As a typical device of a mobile device, a mobile phone will be described herein.

(rescue)

It is divided into mobile phone and charger. The charger contains a radio frequency generator.

The charger 30 is composed of a structure 31 that performs the existing charging role as it is, and additionally as a switch (usually a push switch, 34) to operate the area 32 and 32 to generate a radio frequency. consist of. 32 and 34 are connected via an electric wire 35. In addition, the wireless transmitter 32 receives the power 33 from the mobile phone battery charger 31. If the wireless transmitter (wireless generator) is operated by itself, it does not receive power from the battery charger and operates by attaching a single power supply (battery). At this time, if the battery of the wireless generator is exhausted, replace the battery. If a radio generator enters the charger as described below, the battery is used as a rechargeable battery. In terms of the charger structure, a device is devised so that the wireless generator can be placed in the charger. That is, the shape digs a portion of the charger into a cuboid (52 in FIG. 3) and places the radiofrequency generator (53 in FIG. 3) therein. However, in order to use an external power source, the wireless generator separated from the charger has a connection port for connecting the power supply between the charger and the generator (51 in FIG. 3). 3 shows a picture before the wireless generator enters the charger, and a picture on the right shows the radio frequency generator fits perfectly into the charger. This fits in and the power connection port is engaged. This description assumes that the wireless generator is typically included in the charger because it plays the same role, whether attached to the charger or operated alone.

Referring to Figure 2, the mobile phone (0) is the original mobile phone structure, in addition to its own power supply 11, charger 14, the part 20 for driving the speaker by receiving a radio frequency and the built-in speaker 16 ) This speaker is usually built into the phone, but if it's built in, there's no need to add it. 20 is formed of a wireless receiver 21 and a speaker driver 22 therein, and 21 and 22 are connected to signal lines. If the wireless receiver 21 is already built in the mobile phone, there is no need to install separately. The power source 20 is connected to the power source 11 and the mobile phone power source 10, and the self power source is connected to the mobile phone through the charger 14.

(Operation function)

When the user presses the radio generator switch 34 attached to the charger to find his mobile phone, the radio transmitter (generator) transmits radio 40 and the radio receiver 21 of the cellular phone hidden within a certain distance. Detects the signal. Then, the wireless receiver drives the speaker 16 through the speaker driver 22 (via 15). At this time, the power source for driving the system uses the battery 10 of the cellular phone (through 12), and runs on its own power source 11 when the battery power is exhausted (ie, when the cellular phone is turned off). (Via 13). Self-powered battery is a rechargeable battery, when some of the power is consumed, charges the power from the battery of the mobile phone through the charger.

When the radio transmitter transmits radio, the radio receiver (e.g. Bluetooth) of the cellular phone automatically detects it. However, since Bluetooth, Zigbee, Ruby communication, etc. have the ability to detect the same wireless signal at the same time, whether the wireless receiver has a signal to search for a mobile phone and the command to drive the speaker by detecting it, Built in, the software is performed with the help of the phone's processor. Of course, in the case of computer-oriented portable devices such as smart phones (eg, iPhones) in the near future, the software can be downloaded and used from the outside.

The user locates the sound of the speaker and finds a mobile phone. When the user finds the phone, the random key press will stop the speaker ringing.

The radio frequency generally uses Bluetooth (2.4Ghz, or 900Mhz). The communication distance is about 10m to 100m, and it is a wireless transmission method that can transmit and receive data when necessary. Typically, mobile phones have a built-in Bluetooth transceiver. Alternatively, you can use the 900 MHz frequency. It's used a lot in landline phones. This band is used by many devices at frequencies that do not require government permission. The other way is Ruby. Use 450Khz. Achievement distance is up to 15m. In addition, the Zigbee method can be mastered up to 50m.

Applies to mobile phones or mobile devices.
