Description

CHEERING APPAEATUS

Field of the Invention

The present invention relates to the field of cheering devices.

Background of the Invention

Audience participation in sports games, for example, is considered very essential. Many sports experts describe the audience/team fans cheering or protesting as vital as the sixth player on a basketball team or the twelfth player on a soccer team. Sports team fans all over the world continuously search for new means to cheer or protest in order to increase their influence on the sports games results while increasing, as well, their own enjoyment of the event. For example, fans frequently arrive wearing their favored team uniform, hats, socks, scarves, etc. to attend the events. During the games, fans may perform as an organized group/chorus, shouting interjections according to the immediate situation at the pitch.

Common ways people express themselves at spectacles like sports games, rock concerts, demonstrations, include creating as much noise as they can, by shouting, whistling, applauding, drumming, trumpeting or any other way that creates the desired sound effects. Another common way for fans to increase their impact on the game results and to further their own enjoyment is by performing together as a large body the famous "Mexican wave movement", accompanied by coordinated cheering or booing interjections. All cheering or protesting means that are mentioned above and many more are suitable and relevant for outdoor and indoor events with audience participation, such as sports games, demonstrations, processions, rallies, etc.

A spectator of a show such as a concert or sports match is basically limited to express himself by his own capabilities. He can clap his hands, cheer his team, "boo" the opponent, and so forth. However, spectators, especially of sports events, sometimes feel this is insufficient, and therefore use devices for amplifying their reaction, such as trumpets and the like.

Publication DE4015323 discloses a musical instrument incorporated in a glove. It has a number of operating kegs provided at the ends of each of the fingers and at spaced points across the palm, to allow them to be independently generated by strumming the fingers or pressing the palm of the glove against a solid surface. The glove is coupled via a wireless transmission link to a base unit incorporating an amplifier and a speaker or a handset. The transmitter may be incorporated in the glove wrist band.

Publication JP10277273 discloses a toy that generates sounds as a result of colliding with a wall or a floor in order to dissipate stresses, by fitting an electronic circuit provided with a shock- sensitive sensor, an electric source, a shaper, a voice generator, an amplifier, a speaker, etc., in the inside of the toy and wrapping it with an elastic raw material at the outside thereof.

Publication WO9748092 discloses an interchangeable sound effect device which incorporates and plays sound effects that have been digitally recorded on interchangeable sound cartridges. The device is designed to be used with entertainment and educational type products such as toys, dolls, figurines, books and instructional guides. The sound effect device employs an infrared receiver housed within a durable encasement which straps around the user's waist or is embedded within the doll, figurine, toy, or book. The receiver unit contains an infrared detector, an electronic driving means, an audio speaker, and a sound cartridge that rests within a sound cartridge chamber. The sound cartridge contains a sound enabler chip that stores, in digital form, a number of prerecorded sound effects. In addition, the user can easily remove the sound cartridge and insert one of many other sound cartridges, each containing a different set of sound effects. Finally, the sound effect device uses an infrared transmitter that attaches to an adjustable glove.

Publication US6758769 is considered to be the closest prior art. It discloses a sound effect assembly that attaches to the net of a goal. The sound effect device contains a sensor that either detects the motion of the net or the passing of the ball or puck. When the sound effect assembly is activated, the sound effect device generates audible sounds, preferably of a cheering crowd. Accordingly, each time a goal is made, the sound effect device produces the sounds of a cheering crowd. The sound effect device is produced in a very small housing that hooks onto the net of a goal.

All the methods and devices described above have not yet provided satisfactory solutions to the problem of amplifying a user's reaction to events of a happening, such as a spectacle and sport match.

It is an object of the present invention to provide a cheering apparatus, which improves the ability of a spectator to cheer and boo in a better way than in the prior art.

Other objects and advantages of the invention will become apparent as the description proceeds.

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the disclosure. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail, so as not to obscure the present disclosure.

According to this embodiment, the cheering device is designed as a mobile device which comprises the following modules ^'■

- An audio recorder 10, for recording sound effects such as cheering, booing, and the like. ■ An effect selector 20, for selecting by a user the sound effect to be played upon activation (e.g., cheering, booing, clapping).

- A motion detector 30, for detecting motion of a user's limb, and triggering the playing of the selected sound sample upon detecting a certain level of acceleration or deceleration and on.

An audio player 40, for playing recorded samples or generating signals of desired effects.

- An audio amplifier 50, for amplifying played signal. - A speaker 60, for converting electrical signal of the amplifier into audible sound.

A mobile power source (not illustrated), such as batteries, should be used in order to provide the power required for the cheering apparatus. In addition, a user interface for operating the apparatus is employed (also not illustrated).

The audio unit

Audio recorders are universally well known. Actually, almost every MP3 player includes an audio recorder and player.

The current audio recorders and players make use of non-volatile flash memory as a substitute for the tape utilized in the past. This enables designing miniature audio recorders and players.

The effect selector

According to a preferred embodiment of the invention, the cheering apparatus is adapted to record / reproduce a plurality of cheering effects, such as cheering, booing, clapping, and so forth.

The effect selector is a device by which a user selects an effect to be recorded or played.

For example, a cheering apparatus is adapted to handle only two cheering effects. In this case, a user may decide that one effect is cheering and the other, booing. Thus, when setting the selector to cheering, the recorded or reproduced sound will be of cheering, and when setting the selector to booing, the recorded or reproduced sound will be of booing.

According to one embodiment of the invention, the selector is a switch having a state for each allowed expression (cheering, booing, and so forth). Usually, the state of the switch is indicated by corresponding contacts.

Switches that have two or more states are well known in the art. Such a switch may be based on mechanical elements, electrical elements, electronic elements, and so on.

Fig. 2 schematically illustrates a mechanical effect selector, which may be used in embodiments of the invention.

The effect selector has three states- cheering, booing and clapping. Contacts 22 and 23 correspond to the cheering state; contacts 24 and 25 correspond to the booing state! and contacts 26 and 27 correspond to the clapping state. A user may move the carriage 28 from one state to another. In the illustration, carriage 28 is in the cheering state, thus it connects the corresponding contacts 22 and 23.

A ring counter is basically a circulating shift register in which the output of the most significant stage is fed back to the input of the least significant stage. Fig. 3 illustrates a 3-bit ring counter constructed from D flip-flops 29. The output of each stage is shifted into the next stage on the positive edge of a pulse from switch 21. If the CLEAR signal is high, all the flip-flops except the first one FFO are reset to zero. FFO is preset to 1 instead.

Since the count sequence has 3 distinct states, the counter can be considered as a niod-3 counter. No extra decoding circuit is needed to determine in which state the counter is.

Specified selection vs. cyclic selection

According to one embodiment of the invention, the selector comprises a multi-states switch, each one corresponding to a different cheering effect. A user sets the cheering apparatus to the desired state by setting the switch at the position associated with the desired state. This type of switch is illustrated in Fig. 2.

According to another embodiment of the invention, the user flips from one state to another by hitting a sensor. This can be embodied by a sensor used for flipping from one state to the next state in a group of states. This type of switch is illustrated in Fig.

3.

For example, in case wherein the selector has two states, cheering and booing, a hit switches from one state to the other state, e.g., from cheering to booing! and the next hit on the sensor sets the state from the booing state to the cheering state. In another example, where the selector has three states, such as cheering, booing and clapping, a hit on the sensor switches the cheering apparatus from cheering to booing, the next hit from booing to clapping, the next hit from clapping to cheering, and so on.

Since this type of selector enables selecting the "next" state from a group of states, it is referred to also as "cyclic selector", and "rotating selector".

The sensor of a cyclic switch may be a mechanical sensor

(e.g., a mechanical button that closes a circuit), a microphone that samples a sound, etc. In the latter case, sound may be converted to current, and an electronic circuit thereof may treat a certain level of current and as instruction to switch from one state to the next state.

According to one embodiment of the invention, the cheering apparatus comprises a plurality of pairs, triples, and so on, of cheering effects. A user may select a pair, triple and so on by an additional selector. Thus, for example, in the case of a plurality of pairs, the motion detector switches from a member of one pair to the next member of the same group.

The motion detector

The motion detector 30 is a sensor which detects acceleration / deceleration of an object 40 to which it is connected. Upon detecting acceleration / deceleration of the object 40, an activation mechanism activates the operation of playing the selected sound.

The motion detector 30 comprises the following elements ^:

- a conductive spring 32, which is connected at one end to the rigid object 70>^"

- a conductive ball 34, which is connected to the other end of the spring 32; and

- a conductive casing 36, which is also connected to the rigid object 70.

At the idle state, which is illustrated in Fig. 4a, there is no conductive contact between casing 36 and spring 32. When the rigid object 70 accelerates, spring 32 bends. From a certain level of acceleration / deceleration, as illustrated in Fig. 4b, spring 32 bends such that ball 34 contacts casing 36. The contact closes a circuit through the conductive wires 38 and 39.

The acceleration / deceleration level that causes a contact between ball 34 and casing 36 depends on the characteristics of the spring 32 (such as its length, flexibility, and so on) and on the weight of the ball 34. Applying sensor 30 to a cheering apparatus may be carried out as follows:

Sensor 30 is fastened to a user's wrist. When a user is interested in activating the sound player to play the selected sound, he has to shake his hand with sufficient intensity that sensor 30 indicates a desired acceleration / deceleration. However, since the user accelerates / decelerates his wrist as a reaction to an event that happens at the event where he is a spectator, the activation of the cheering effect is actually a result of his own behavior at that moment.

For example, assume the cheering apparatus is set to two states, cheering and booing, and the current state is cheering. If the user's favored team scores in a basketball match, the user may shake the hand to which the motion sensor is attached until the motion sensor activates the sound effect. At this point, the ball may pass to the opponent, upon which the user hits the selector's sensor in order to switch to the booing effect. When the opponent is approaching the user's favored team, he may shake his hand in order to activate the booing sound.

The motion detector illustrated in Figs. 4a and 4b is merely an example, and those skilled in the art will appreciate that other types of motion detectors may be employed for the same purpose.

Thus, the example of Figs. 4a and 4b is merely illustrative and not restrictive. The amplifier and the speaker(s)

All the activities of the apparatus are designed to emit a loud sound, and as such, the amplifier and the speaker(s) have a substantial importance to a cheering apparatus.

The desired audio level for a cheering apparatus is about 120db. Of course, this is only an example, and a cheering apparatus may be designed to well exceed this level.

Some conflicting factors are involved in selecting an amplifier- on the one hand, the produced sound of the amplifier has to be at such a level that it is heard well on the sports ground, and as such, it requires an appropriate power source, amplifier and speaker. On the other hand, the entire cheering apparatus has to be worn on the human body, such as a hand, and accordingly, it has to be suitable for easy user carrying.

Presently, flat speakers are available on the market. A flat speaker may be a benefit when designing a compact cheering apparatus.

As per the power of the amplifier, compact amplifiers which may by operated by battery power are available on the market, and they may produce the desired audio level for the purpose of cheering. Design

As mentioned above, conflicting factors are involved in selecting an amplifier^ on the one hand, the apparatus has to be relatively small, such as a handheld device, and on the other hand, it must be capable of reaching a level of that is heard on the sports ground.

The cheering apparatus 100 is designed as a handheld device, which comprises one or more straps 82 for attaching the apparatus 100 to a human's limb, such as to a hand, foot, or the like. In this case both the effect selector and motion detector are embedded in the casing.

Also illustrated in Fig. 5 is a speaker 60, an ON/OFF button 84, a LED 86 for indicating if the power is on, a volume slider 88, a recording button 90, and a microphone 92.

In this case, both the effect selector 20 and motion detector

30 are external, and connected to the casing of apparatus 100 by wires 89 and 39 respectively, thereby allowing attaching the casing, which is a relativelyheavy component, to the user's belt, while the selectors or at least the sensors thereof, which are relatively-light components, are attached to the hand or elsewhere by straps (not illustrated) and the like. For example, the sensors 20 and 30 may be connected to a strap worn by a user via Velcro.

In order to inform a user about the selected sound effect, the remaining power on the batteries, and so forth, one or more visual indicators, such as LEDs (Light Emission Diode) are used.

The power consumption of a LED is relatively low, and therefore it may be a suitable solution for the visual indicator.

Operating a cheering apparatus

Firstly, a user inserts batteries into the "batteries housing", which is disposed within the casing of the apparatus.

Recording- The user selects the desired cheering effect, such as cheering, booing, and so on. Then he presses the RECORD button 90. While holding the RECORD button 90 pressed, the sound associated with the selected cheering effect is recorded. When finished, the user releases RECORD button 90.

Setting the volume level: Slider 88 is used for setting the volume level of the reproduced sound.

Cheering^ Assuming the cheering apparatus 100 has two states, cheering and booing, and the current state is cheering: if the user's team scores in a basketball match, the user may shake the hand to which the motion sensor is attached with such intensity that the motion sensor 30 activates the sound effect. At this point, assuming the ball passes to the opponent, the user hits the sensor of the effect selector 20 in order to switch to booing. When the opponent is approaching the user's team, he may shake his hand in order to activate the booing sound.

A preferred design

Fig. 7 schematically illustrates a cheering apparatus, according to a preferred embodiment of the invention.

According to this embodiment of the invention, the apparatus is designed to produce a plurality of pairs of effects. A user selects the desired pair by moving the button 95 of slider 96. Button 21 flips the selected state from the cheering state to the booing state and vice versa. The operation of button 21 may be carried out by an electronic scheme such as of Fig. 3.

When in the cheering state, the cheering indicator 86a (which may be embodied as a LED) is on and the booing indicator 86b is ofβ and when in the booing state, the booing indicator 86b is on and the cheering indicator 86a is off.

Button 96 is used for recording a sound effect, and indicator 86c indicates the recording action. Another preferred design

Fig. 8 schematically illustrates a cheering apparatus, according to another embodiment of the invention.

According to this embodiment of the invention, the apparatus comprises a plurality of buttons 66 for selecting a cheering sound effect, and corresponding indicators 67, such as

LEDs, for indicating the selected effect from among the other effects. According to this embodiment of the invention, in order to select a cheering effect, the user has to press the corresponding button, in contrast to a slider where the user has to drag the carriage to point on selected cheering effect, as in the embodiment of Fig. 7. Thus, the selection buttons are a fast and simple means for selecting a sound effect.

Buttons 68 and the indicators 69 thereof are directed to booing sound effects. They operate correspondingly to the cheering buttons 66 and indicators 67. This arrangement allows independent selection of cheering and booing effects, in contrast to the embodiment of Fig. 7 wherein the user can select only pairs of cheering / booing sound effects.

Buttons 74 and 76 are used for arbitrarily selecting the next effect to be played: cheering or booing. When a user presses button 74, the sound effect to be played upon activating the cheering / booing sound effect will be of cheering, and when a user presses button 76, the sound effect to be played upon activating the cheering / booing sound effect will be of booing. Buttons 74 and 76 may be used also as indicators. This can be carried out, for example, by including a LED in each button. A well known LED technology enables to produce LEDs whose Light is green, and LEDs whose light is red. Thus, the cheering indicator may comprise a green LED, while the booing indicator may comprise a red LED. Employing green and red LEDs may be used as an additional indication for the selected sound effect, cheering or booing.

Button 21 is used for switching from cheering to booing and vice versa, i.e., such as a flip-flop.

Slider 64 comprises three states ■ On, Off and Mute. The mute is used for temporary shutting the speaker without turning off the power of the apparatus.

Also illustrated in Fig. 8 is an external microphone 91. When microphone 91 is plugged into apparatus 100 and slider 64 is on the ON state, apparatus 100 may be used as a loudspeaker by which a user may amplify his voice. The microphone may be used also for recording sound effects. Of course a different user interface may be used for activating the loudspeaker, such as a dedicated button.

Slider 88 is used for selecting a volume level, such as low, medium and high,

Some additional features which may be added are, for example, a housing 62 for a replaceable non-volatile memory card (such as flash memory, SIM, and so forth), a USB connector 78, for connecting the cheering apparatus to other devices, such as a personal computer, to another cheering apparatus, and so on. The replaceable memory chip may be used, for example, for storing pre-recoded sound effects, and so forth.

Apparatus 100 may communicate with another device such as a computer or another cheering apparatus by a variety of means, such as, for example, a USB connector 78, a Bluetooth transceiver 70, an infrared transceiver (not illustrated), and so on.

The cheering apparatus 100 may also comprise a light effect generator 72, such as a laser beam.

According to one embodiment of the invention, some of the sound effects are erasable, and some of them are not erasable. For example, assuming there are six cheering sound effects, the user may replace sound effects 3"6, but not sound effects 1 and 2. According to one embodiment of the invention, a reset button (not illustrated) restores the factory setting of sound effects and the like.

According to one embodiment of the invention, the cheering apparatus is upgradeable. A cheering apparatus may be upgraded, for example, by replacing non-volatile memory in housing 62, downloading information via the USB connector 78, and so on. By upgrading a cheering apparatus, new operational features and sound effects may be added, and so on. Coordinating a plurality of cheering devices

One of the objects that a cheering apparatus has to face with is coordination with additional cheering devices, since the sound produced by a plurality of cheering devices playing the same sound effect at the same time is more intensive than the effect produced by a single cheering apparatus.

According to one embodiment of the invention, coordination between a plurality of cheering devices can be carried out by intercommunicating between the cheering devices. Fig. 9 schematically illustrates a plurality of cheering devices coordinating their sound effect, according to one embodiment of the invention. Each of the cheering devices 100 are coupled with an RF receiver, through which "instructions" are received from a master apparatus 110.

The master apparatus 110 may comprise the same user interface as the "slave" 100, except that it has to use an RF transmitter. Upon activating a cheering sound effect by the master 110, a corresponding signal is transmitted by the master 110. Upon receiving a signal from master 110 at a slave 100, the corresponding sound effect is played. For example, the master transmits alphanumeric characters via an RF signal. Upon receiving a string such as "C2,3" the slave may play the cheering effect number 2 in volume level 3. Upon receiving a string such as "B 1,4" the slave may play the booing effect number 1 in volume level 4. The transmitted signal or the transmitted content may be encrypted, in order to prevent interference of an opponent. The encryption / decryption key may be provided via the USB connector, DIP switches (not illustrated), and so on.

Fig. 10a is a sectional view which schematically illustrates a motion detector, according to another embodiment of the invention. Fig. 10b is the section F-F of Fig. 10a.

The motion detector illustrated in Figs. 10a and 10b allows detecting motion in two perpendicular directions, such as vertical and horizontal. For example, assuming the cheering apparatus is secured to a user's hand, when the user moves the hand vertically, ball 34 touches one of the conductive pads 33, and when the user moves his hand horizontally, ball 34 touches one of the conductive pads 35. Assuming casing 36 is non-conductive, a contact between ball 34 and a conductive pad 33 may trigger playing the selected cheering sound effect, while a contact between ball 34 and a conductive pad 35 may trigger playing the selected booing sound effect.

Advantage over the prior art

The cheering apparatus of the present invention can be used as means for elevating the effect a user wishes to produce, such as cheering or booing, in a spectacle such as a sports game, rock concert, in a demonstration, and so on. It actually allows a user to expand his ability to express himself vocally, and also visually in case the cheering apparatus comprises means for generating visual effects. A user of a cheering apparatus is free to record any sound he is interested in, including sound produced by animals, music, the user's voice, the voice of any individual, and actually any recordable audio signal. The recording may be carried out even during the spectacle itself, which actually allows a user to increase a natural sound of cheering and booing. In addition, the apparatus may use pre-recorded sound effects, generated sound effects, and so on.

By employing a cyclic effect selector 20, the transition between the states is actually a very simple operation.

The cheering apparatus of the present invention may be used also for other situations, and actually any gathering of people. Furthermore, the cheering apparatus may be used also for increasing the expression of additional emotions, such as protesting.

Activating a plurality of cheering devices simultaneously during a sport game creates a significant advantage for their sports team. Coordinated and loud sound effects played at crucial moments from a direction where the fans of a team are concentrated creates an impression that a bigger crowd is cheering, which may result with positive impact on the players of the team.

While certain features of the invention have been illustrated and described herein, the invention can be embodied in other forms, ways, modifications, substitutions, changes, equivalents, and so forth. The embodiments described herein should be considered as illustrative and not restrictive.
