In addition, the temple on the first side and the drop end on the first side, and the temple on the second side and the drop end on the second side are adapted to be an independent component, respectively, being configured to be capable of being jointed to or separated from each other, and being electrically connected to or disconnected from each other, and further the temples on the first and second sides are configured to be attachable to or detachable from the frame, respectively, whereby selection and replacement of the frame, temple, and drop end being made possible, and thus an advantage being offered that development of a glasses-type acoustic device as commodities having a variety of designs is allowed.
Some of the embodiments will be described in detail, with reference to the following figures, wherein like designations denote like members, wherein:
Hereinbelow, embodiments of the present invention will be explained with reference to the attached drawings.
Embodiments of the present invention is a glasses-type acoustic device incorporating a sound generating device in temples of a pair of glasses, and as shown in
The temple 1 on the second side and the drop end 3 on the second side are independent and separate parts, in other words, parts having replaceability, and they are configured to be able to be jointed to or separated from each other, and able to be electrically connected to or disconnected from each other. Likewise, the temple 2 on the first side and the drop end 4 on the first side are independent and separate parts, in other words, parts having substitutability, and they are configured to be able to be jointed to or separated from each other, and able to be electrically connected to or disconnected from each other.
In order to enable the temple 1 and the drop end 3 to be jointed to or separated from each other and electrically connected to or disconnected from each other, and enable the temple 2 and the drop end 4 to be jointed to or separated from each other and electrically connected to or disconnected from each other, for example, a connector 11 for supplying power to drive the electronic circuit 5 is disposed on the rear end face of the temple 1, a connector 11 for supplying power to drive the electronic circuit 6 being disposed on the rear end face of the temple 2, and a connector 12, which is mated with the connector 11, is disposed on the front end face of the drop ends 3 and 4, which are opposed to the rear end face of the temples 1 and 2, respectively. Moreover, the connectors 11 and 12 are adapted to have a corresponding male and female connector structure, or a pin plug and pin jack structure, whereby the temple 1 and the drop end 3, and the temple 2 and the drop end 4 can be jointed to or separated from each other, respectively.
Further, the temple 1 on the second side and the temple 2 on the first side are configured to be attachable to or detachable from the frame 13, respectively. Still further, as the frame 13, those which have a variety of shapes, those which are made from various materials, or those which are provided with various colors are prepared, while those which are to be used as a sun glass, powered spectacles, or the like, being prepared. The temples 1 and 2 are adapted to be attachable to or detachable from any one of such many and diversified types of frames 13, respectively, such that the user can use an appropriate frame 13 as necessary.
As a configuration that allows the temples 1 and 2 to be attachable to or detachable from the frame 13, the configuration in which a protruding part 14 is formed at the respective ends of the temples 1 and 2, while, in the respective side parts at both ends of the frame 13, a hinging part 15, which grips the protruding part 14, is formed, and from the hinging part 15, a setscrew is inserted through the protruding part 14 is convenient.
In a portion of the respective drop ends 3 and 4, in other words, a portion between the connector 12 and the electric cell housing part, there is disposed a flexible part 16, which has flexibility. By doing so, the drop ends 3 and 4 are made easier to be fitted to the geometry of the head of the user, and it is made possible to secure the intrinsic function of the drop ends 3 and 4 that is to hold the pair of glasses when it is worn.
With the glasses-type acoustic device configured as described above, the temple 1 on the second side and the temple 2 on the first side are each provided with a power supply (an electric cell 9 or 10) to thereby eliminate the need for supplying of power through the frame 13, which is located between the temples 1 and 2, and, since the electronic circuit 5 on the second side and the electronic circuit 6 on the first side can be connected to each other by a radio system, the frame 13 can be separated from the temples 1 and 2, which incorporate the electronic circuit 5 and the sound generating device 7, and the electronic circuit 6 and the sound generating device 8, respectively.
The glasses-type acoustic device in accordance with embodiments of the present invention is configured as above, and thus it is capable of being used as, for example, a stereo headphone. In this case, in the electronic circuit 5 in the temple 1, which constitutes one of the temples on both sides, a main substrate having a circuit for receiving a Blue Tooth® (trademark) signal from a piece of external equipment, and a radio transmission circuit for separating a signal from the received signal to send it out to another channel is incorporated, and in the electronic circuit 6 in the temple 2, which constitutes a pair with the temple 1, a receiver and an amplifier or means for receiving and amplifying a signal that is sent from the main substrate is incorporated.
Further, the glasses-type acoustic device in accordance with embodiments of the present invention can also be used as a hearing aid one. In this case, the electronic circuit 5, which is used as a hearing aid, being incorporated in the temple 1, and the electronic circuit 6, which is used as a hearing aid one, being incorporated in the temple 2, can be each provided with a circuit configuration for hearing aid that is independent of the same on the other side, whereby the characteristics and the sensitivity of the electronic circuits 5 and 6 can be set and adjusted more finely to the user's hearing abilities on the second or first side, respectively.
The features of the glasses-type acoustic device in accordance with embodiments of the present invention include:
1) Since the frame 13 is independent of the temples 1 and 2, the degree of freedom of design is high, and further, each of the drop ends 3 and 4 is adapted to be replaceable, which means that the electric cells 9 and 10 can be prepared as a spare, respectively, whereby a time loss that could be caused by charging the electric cell can be avoided.
2) Each particular component can be freely replaced with another same component by the purchaser, whereby the purchaser can use an appropriate glasses-type acoustic device in accordance with a variety of situations.
3) It is applicable to a stereo headphone, a hearing aid, and the like, and in case where it is used as a hearing aid, the characteristics and sensitivity can be set and adjusted to the respective hearing abilities of the user on the first and second sides.
4) Since the electric cell housing parts (the drop ends 3 and 4) are separable from the main body, separation disposal thereof that is needed in scrapping the product can be easily conducted.
The glasses-type acoustic device in accordance with embodiments of the present invention has a number of features as described above, and thus it provides a high industrial applicability.
Although the present invention has been disclosed in the form of preferred embodiments and variations thereon, it will be understood that numerous additional modifications and variations could be made thereto without departing from the scope of the invention.
