Description

A PREGNANCY BELT WITH INTEGRATED SOUND REPRODUCTION FIELD OF INVENTION [0001] The present invention relates to sound and vibration reproduction for unborn children.

BACKGROUND OF THE INVENTION

[0002] In recent years the theory that music may positively affect the cognitive performance or intellectual development of children has been accepted by many parents of young children. A popularized version of this idea has been dubbed "the Mozart Effect" whereby proponents suggest that early childhood exposure to the music of recognized luminaries of classical music has a beneficial effect on some aspects of intellectual development or performance. Certainly most parents would accept that it is vitally important to communicate with infants long before they are able to respond in kind. Indeed, many parents begin to speak to their children while they are still in the womb.

[0003] It is a commonly held belief that an unborn fetus is able, after a period of development, to sense sound or vibration while in utero. Since time immemorial parents have noted that the unborn seem to react to the effects of sound while in the womb at later stages in their development. Some sounds seem to result in increased heart rate or an apparent startled reaction while the sound of a parent's voice appears to sooth the unborn infant in some cases. In view of these beliefs, parents may wish to expose an unborn child to musical or other auditory stimulus.

SUMMARY OF THE INVENTION

[0004] It is an object of the invention to provide a system for communicating sound or vibration to an unborn fetus in the form of vibrations derived from music, spoken word, or other sound.

According to an aspect of the present invention, there is provided a pregnancy belt wearable across an abdomen of a pregnant woman. The belt includes a sound reproduction member positionable on the abdomen of the pregnant woman, the sound reproduction member having a vibration speaker directed toward an unborn child carried by the pregnant woman when positioned on the abdomen of the pregnant woman, and an audio reproduction module electrically coupled to the vibration speaker, the audio reproduction module providing a musical signal. The belt further includes a back massaging member adjustably coupled to the sound reproduction member, and a user interface for controlling the sound reproduction member and the back massaging member. When the pregnancy belt is worn across the abdomen of the pregnant woman and the sound reproduction member activated, the vibration speaker converts the musical signal into vibration for the unborn child.

DETAILED DESCRIPTION

[0006] An embodiment of the present invention is illustrated in Figure 1. A pregnant woman wears a pregnancy belt 102 positioned so as to support a plurality of vibration speakers 104 that are integrated within the belt and directed toward the unborn child. In an embodiment of the present invention, the belt includes two or three vibration speakers 104, which are located medially across the front expanse of a pregnant woman's abdomen. However, the belt may include a single vibration speaker or more than three vibration speakers located within the belt so as to direct sound or inaudible vibration toward the unborn child. The vibration speakers 104 are typically audio speakers as are well known in the art but may be any type of transducer that is small enough, and efficient enough, to convert an incoming analog or digital electrical sound signal into vibration or sound energy when mounted within the belt of the current invention.

[0007] Figure 2 presents a partial exploded view of an embodiment of the present invention. The pregnancy belt 102 includes a sound reproduction member 202, and a back massaging member 204. Controlling the sound reproduction member 202 and the back massaging member 204 is a user interface (discussed below). The sound reproduction member 202 and the back massaging member 204 are secured to one another by 206, which in one embodiment of the invention is a stretchy and breathable elastic fabric. This ensures that the pregnancy belt 102 can be securely positioned about the pregnant woman's midsection. It also helps adjust the belt to the varying sizes of the pregnant woman at different stages of pregnancy (discussed further below) Alternatively, the fabric 206 may be replaced with other securing mechanism such as Velcro™ straps, belts with buckles or other reasonable securing mechanisms.

[0008] The pregnancy belt 102 may also be housed in a multi-fabric shell 210, 212 to increase the level of comfort of the wearer. As shown in Figure 2, a first multi-fabric shell portion 210 houses the sound reproduction member 202 and a second multi-fabric shell portion 212 houses the back massaging member 204. Since the shell is made of multiple layers of fabric, the inner portions 210B, 212B of the pregnancy belt 102 may feature a soft plush fabric on body facing surfaces for comfort.

[0009] Referring to Figures 2 and 3, the sound reproduction member 202 and back massaging member 204 will now be described in detail. The sound reproduction member 202 has at least one vibration speaker 104 positioned on the front portion of the belt 102. In Figure 2, three vibration speakers 104 are shown. The vibration speakers are positioned at the front of the belt 102 in such a way that when the belt 102 is worn by the pregnant woman, the vibration speakers 104 are directed toward an unborn child carried by the pregnant woman. When a musical signal is provided by an audio reproduction module 208, the vibration speakers 104 converts the musical signal into vibration for the unborn child. The audio reproduction module 208 may be a small-form-factor electronic device for the reproduction of electronic music formats like the ubiquitous MP3 format (MPEGl audio layer 3). Other audio reproduction technologies (compressed and uncompressed) capable of providing the musical signal are suitable for this invention.

[0010] As depicted in Figure 3, the vibration speakers 104 may be housed in the first multi- fabric shell portion 210 having an outer layer 210A and inner layer 210B. In this embodiment, the outer layer 210A is a luminescent fabric and the inner layer 210B is a soft material since it may come in direct contact with the wearer's skin. A luminescent fabric uses LEDs embedded in a fabric material to create a flexible reconfigurable display. A luminescent display technology such as Philips Lumalive™ light emitting textiles may be employed to create a programmable multicolored display while maintaining the flexibility desirable in a garment. The luminescent display may be used in a variety of ways. For example, the display may be employed to display various animations synchronized to musical signal. Animations may be created or retrieved from a website by a user on their home computer and loaded onto the device for display. As another example, the display animations may be synchronized to a story. Various other animations may be employed to create a user interface environment for the device. Additionally, or alternatively, a more conventional touch screen, touch sensitive controls or a flexible LED touch screen may be employed to provide the user interface for controlling the sound reproduction member 202 and the back massaging member 204. While the touch screen may be dynamically indicated, the present invention also contemplates the use of passively indicated touch screen such as sewn seam or silk screen print on the front portion of the belt 102. The sound reproduction member 202 may also include an external interface to allow an external device to control the functionalities of the pregnancy belt 102. For example, an iPhone™ with an iPhone™ application may be used to control the sound reproduction member 202 and the back massaging member 204. Such external device may be used in place or in addition to the user interface provided on the pregnancy belt 102.

[0011] Sandwiched between the outer layer 210A and inner 210B are vibration speakers 104, and audio reproduction module 208. In this embodiment, a flexible hardware housing 213 is provided to accommodate the vibration speakers 104, the audio reproduction module 208 and all the associated wiring. Alternatively, the vibration speakers 104 and the audio reproduction module 208 may be sewn into the first multi-fabric shell portion 210. As shown, it is also contemplated that a cover 214 may be provided to help protect the audio reproduction module 208. A microphone 216 may also be provided on the audio reproduction module 208 or the flexible hardware housing 213 to enable recording for playback.

[0012] Similarly, the back massaging member 204 may be housed in a second multi-fabric shell portion 212 including an outer layer 212A and inner layer 212B. The back massaging member 204 may provide vibration or pulsation to provide muscle relief to the pregnant woman. In one embodiment, the back massaging member 204 comprises three discrete massage units which gives the massage unit additional flexibility. The integrated back massaging member 204 serves to relax and sooth the expectant mother and may therefore indirectly contribute to the contentment of the unborn child in cases where it seems that the baby appears to be sensitive to the mother's feelings of discomfort or agitation. The back massaging member 204 may be operated whether or not the audio reproduction module 208 is operated. The massaging member 204 may also be controlled with the touch sensitive controls, by manually switching on or off the massaging portion, or remotely using an iPhone™ application or wirelessly networked computer.

[0013] In an embodiment of the present invention, the audio reproduction module 208 includes an electronic storage means such as a hard drive. Alternatively, the audio reproduction module 208 may rely on portable electronic memory such as flash memory devices. Music or other sound data is loaded or organized on the audio reproduction module 208 using a wired or wireless connection through any number of means well known in the art such as USB, IEEE 1394, Wi-Fi™, or Bluetooth™. In one embodiment of the invention, the audio reproduction module 206 is an iPod™. In this case, the sound files resident on the device may be organized utilizing an iPhone™ application.

[0014] Now turning to Figures 4A-4D, the adjustability of the pregnancy belt 102 will be described. As shown in Figure 2, a securing mechanism 206 adjustably couples the sound reproduction member 202 and the back massaging member 204. In the embodiment shown, the sound reproduction member 202 and back massaging member 204 are further housed in the first and second multi-fabric portions 210, 212, which are adjustably coupled by the stretchy and breathable elastic fabric. During the early stages of pregnancy (Figure 4A), the pregnancy belt 102 is minimally stretched. However, as months go by and the unborn child begins to grow, the stretchy and breathable elastic fabric 206 is able to accommodate comfortably the increased size (Figures 4B-4D) of the mother-to-be. As discussed above, in place of the stretchy and breathable elastic fabric, other adjustable securing mechanism, such as Velcro™ and belt with buckles, may be used.

[0015] Audio reproduction by the audio reproduction module 208 is not limited to music recordings. The sound of parents' voices or soothing natural sounds are examples of other sounds that parents may wish to reproduce for their unborn children. The audio reproduction module 208 advantageously includes a microphone 216 for recording sound samples. A lullaby, a parent's voice, or a child's story are examples of sounds that may be recorded by expectant parents for reproduction. In recording mode, the device display provides visual feedback corresponding to the recorded level of the sound input. Alternatively, a user can create their own audio files using other equipment to be loaded onto the device in the same way as regular music files.

[0016] In a further embodiment of the current invention, an audible full rage audio speaker 218 may be included to reproduce audible music in air. Thus, the pregnancy belt 102 may also be used before or after the child is born as a music playing device. Using the device in this way may promote a sense of continuity for the baby as familiar sounds are reproduced. Referring to Figures 5A-5D, various post-birth uses of the pregnancy belt 102 are shown. In Figure 5 A, the pregnancy belt 102 is hung nearby the infant. For example, the pregnancy belt 102 may be hung on a crib or a stroller, or placed on a wall of the infant's room. In this use, the belt may use the audible speakers 218 to produce familiar sounds in the air for the infant. The pregnancy belt 102 may also be used to help the infant fall asleep as depicted in Figure 5D, for example, by playing a bed time story. As the infant grows up, the pregnancy belt 102 may be used as a learning tool as shown in Figures 5B and 5C. The infant may interact with the touch screen incorporated into the pregnancy belt 102.

[0017] In this specification and the appended claims, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs.

[0018] It will be further understood that the terms "comprises" or "comprising", or both when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

[0019] One or more currently preferred embodiments have been described by way of example. It will be apparent to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention.
