Description

Handheld device

The present invention relates to a hand held device. More specifically, the handheld device of the present invention has an antenna and a function key that is coupled to the function key to eliminate the area required on the hand-held device to initially set up the antenna.

At present, handheld devices have become an indispensable necessities for modern people's lives. In order to increase product competitiveness, various manufacturers have integrated various wireless communication modules into handheld devices to provide more applications. For example, the handheld device can be a cell phone, a Personal Digital Assistant (PDA), a Personal Notebook, a Tablet Personal Computer, a satellite navigation device. Satellite Positioning Navigation Device or any handheld device with communication function. The handheld devices described above may include a transmission module (eg, Bluetooth Bludetooth, Wireless Broadband WiFi/WiMax/LTE) and a Mobile Communications module. The handheld device may also include a wireless LAN (WLAN) module, a Digital Video Broadcasting (DVB) module, and a Global Positioning System module, and may further incorporate actions. The functions of the telephone include a transmission module and a mobile communication module. The satellite positioning navigation device, in addition to the global positioning system module, is more likely to include any combination of the above wireless communication modules.

Since the overall size and exterior design of today's handheld devices are becoming more and more sophisticated, handheld devices that are thin, uniform, or metallic are not. The market is looking forward to it. However, since each of the foregoing wireless communication modules needs to transmit an antenna through a set of antennas to transmit or receive signals, and the antenna is disposed, the metal radiator is formed on the non-conductor material, and is prevented from being held by the hand. Other metal materials (such as metal casings or related components) in the device are covered or contacted. At the same time, the internal space of the handheld device is getting smaller and smaller, and how to set the relevant components in an appropriate position is also a problem to be solved. To this end, more and more manufacturers have placed antennas on the casing of handheld devices to avoid interference. However, when designing the outer casing of the hand-held device, a special block must be additionally reserved for setting the antenna, so that the setting of the block has destroyed the consistency of the outer casing of the hand-held device and contradicts the current design trend. .

In addition, if the outer casing of the hand-held device is made of a metal material, a non-metallic block must be additionally reserved for the antenna to ensure that the antenna is interfered by the metal material and the wireless transmission and reception quality of the hand-held device is reduced. . As a result, not only the inconvenience of the outer casing of the hand-held device is caused in the manufacturing process, but also the overall structure of the hand-held device is limited, and the outer casing will also sacrifice its metallic texture due to the arrangement of the antenna.

In summary, in the limited space of the device, and in a limited handheld device, the appearance uniformity or metallic texture of the outer casing is increased without affecting the configuration of other components of the device, which is urgently needed in the industry. aims.

It is an object of the present invention to provide a hand-held device having a function key and a communication module. The antenna of the communication module is disposed in a space defined by the function key, so that the antenna is combined with the function key, so as to save the area of the conventional handheld device in which the antenna is reserved, thereby maintaining the appearance of the outer casing of the handheld device. consistency, And when a metal casing is used, the area in which the casing is made using the metal material can be increased. In this way, through the antenna arrangement of the present invention, the appearance consistency or the metallic texture of the handheld device can be increased, thereby increasing the competitiveness of the handheld device.

To achieve the above objective, the present invention discloses a handheld device including a body, a first function key, and a first antenna. The first function key is coupled to the body and defines a first space at the body. The first antenna is placed in the first space and combined with the first function key.
