2. Description of the Related Art
Portable electronic communication devices that do not need to be held (such as wireless earphones) usually include an earphone and a microphone for receiving and transmitting voice data. In order to satisfy the requirements of users, allowing communication at anytime and anywhere, as well as providing excellent communication, the earphone is usually plugged into the ear of the user.
Because the portable characteristics of wireless earphones are their key selling point, the structure of a wireless earphone is usually light and thin, and strength is disregarded. Of course, the wireless earphone has to satisfy the characteristics of being handy and durable. Therefore, when a user is not using the wireless earphone, the wireless earphone can be placed into a pocket, a handbag, or a drawer etc, and bears a degree of external force caused by its users or its environment so that its structure is still intact.
FIG. 1 shows a wireless earphone of the prior art. The wireless earphone includes a housing 1a, an earphone 2a, and a microphone 3a. The housing 1a is rectangular and arced. At one end of the earphone 2a, there is an amplifier 21a. The earphone 2a protrudes from one side of the housing 1a. The amplifier 21a of the earphone 2a is placed into the ear of the user to receive sounds clearly. In the housing 1a, there is a Bluetooth wireless receiving and sending device (not shown in the figure). Therefore, voice signals of the portable electronic device (such as a cell phone) can be transmitted. The microphone 3a is located at an end of the housing 1a that is far away from the earphone 2a that is a sending port for receiving the user's voice.
However, the wireless earphone of the prior art has a problem in that the earphone 2a can be easily broken. Because the earphone 2a protrudes from one side of the housing 1a, the connection point of the earphone 2a and the housing 1a (the torque is maximum) will be broken when an external force is exerted upon it. Therefore, the user cannot place the wireless earphone arbitrarily. It is inconvenient for the user.
The portable wireless earphone has to overcome challenges from its users and its environment. However, the wireless earphone of the prior art cannot overcome these problems.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference is made to FIGS. 2 ̃8. The Bluetooth earphone having a semi-automatic receiving function includes a housing 1, an earphone 2, a microphone 3, a first flexible portion 4, a button 5, and a second flexible portion 6. The housing 1 is rectangular. The housing 1 includes a first semi-shell 11 and a second semi-shell 12. The first semi-shell 11 and the second semi-shell 12 are assembled together by using a wedged method, a screwing method, or a supersonic method to form the housing 1.
One end of the housing 1 has an earpiece receiving bay 13 arranged thereon. One end of the housing 1 indents to form the earpiece receiving bay 13 and the earpiece receiving bay 13 has a rectangular opening space. The dimensions of the earpiece receiving bay 13 allow it to receive the earpiece 2. Two side surfaces of the earpiece receiving bay 13 that are adjacent to the bottom of the earpiece receiving bay 13 have a pair of circular pivoting holes 14. There is a button base 15 in the housing 1, and the button base 15 is adjacent to the earpiece receiving bay 13. There is an assembling hole 151 on the button base 15. There are four wedged slots 152 on the inner wall of the assembling hole 151. The wedged slots 152 are disposed at an interval with 90 degrees.
The microphone 3 is located in the housing 1. The microphone 3 is located at one end of the housing 1 that is far away from the receiving slot 13 and is used as a sending port. The microphone 3 is close to the user's mouth to receive the user's voice. There is a Bluetooth wireless communication device (not shown in the Figures) in the housing 1. The Bluetooth wireless communication device is electrically connected with the earphone 2 and the microphone 3 in the housing 1 to perform a sound signal transmission with a portable wireless communication device (such as a cell phone).
The earpiece 2 is located in the earpiece receiving bay 13. One end of the earpiece 2 has a speaker 21. When the earpiece 2 is being used, the speaker 21 is extended into the ear of the user. A second end of the earpiece 2 that is far away from the speaker 21 has a pair of pivoting shafts 22. The pair of pivoting shafts 22 extends from two opposite locations on the surface of the earpiece 2. The shape of the pivoting shafts 22 is a circular column that corresponds to the pivoting hole 14 of the earpiece receiving bay 13. The two pivoting shafts 22 of the earpiece 2 are pivotally coupled in the pivoting holes 14 located on two sides of the earpiece receiving bay 13 and retractable into the earpiece receiving bay 13. Thereby, the earpiece 2 is selectably retained between a retracted position and a deployed position. The earpiece 2 is received in the earpiece receiving bay 13 and can be rotated to an outside of the earpiece receiving bay 13.
The first flexible member 4 is a twisted spring. The first flexible member 4 is formed by bending the flexible wire. The first flexible member 4 is urgingly arranged between the housing 1 and the earpiece 2. The first flexible member 4 has a first end portion 41 and a second end portion 42. The first end portion 41 and the second end portion 42 respectively contact the housing 1 and the earpiece 2 to provide a flexible force for the earpiece 2 so that the earpiece 2 can escape from the earpiece receiving bay 13 and be located at the using location.
The button 5 is used for controlling the earpiece 2 to eject. The button 5 is operably arranged at the assembling hole 151 of the button base 15 of the housing 1. The button 5 can move upwards and downwards on the button base 15. One side of the housing 1 has a through hole 16 so that one end of the button 5 passes through the through hole 16 so that it is exposed to an outside of the housing 1. Therefore, the button 5 can be pressed easily. The outer wall of the button 5 protrudes to form four wedged blocks 51. The wedged blocks 51 are disposed at an interval with 90 degrees. The wedged blocks 51 correspond to the wedged slots 152 to from a retaining mechanism.
The button 5 corresponds to one pivoting shaft 22 of the earphone 2. The key bodies 52 protrude from the button 5. Two key slots 23 are indented on the pivoting shaft 22 and correspond to the key bodies 52. The two key bodies 52 are movably plugged in the key slots 23 so that the button 5 is connected with the earphone 2 and both can be rotated synchronously. Another side of the housing has a second through hole 17. The second through hole 17 is installed with a decorating cover 18. The decorating cover 18 is opposite to the button 5 and merely provides a decorative function.
The second flexible portion 6 is located between the button 5 and the earphone 2. The second flexible portion 6 is a compressed spring. Two ends of the second flexible portion 6 respectively contact the earphone 2 and the button 5 to provide a recovery force for rising the button 5 and making the wedged block 51 of the button 5 be wedged within the wedged slot 152 so that the earphone 2 can be firmly fastened in the receiving slot 13.
When the user wishes to use the Bluetooth earphone, the user presses the button 5 to escape the wedged blocks 51 from the wedged slots 151 and release the earphone 2. The earphone 2 utilizes the twisted force of the first flexible portion 4 to eject the earphone to the using location (as shown in FIG. 7). Thereby, the earphone 2 protrudes from one side of the housing 1 and the speaker of the earphone 2 extends into the ear of the user, and the user can hear sounds clearly.
When the user is not using the Bluetooth earphone, the earphone 2 is received in the receiving slot 13 (as shown in FIG. 8). By utilizing the receiving function, the wireless earphone can be placed in a pocket or a handbag. The problem of the earphone 2 protruding outside of the housing 1 and being broken due to the impacts of external forces is overcome.
The user can enclose or expose the earphone according to the user's operation requirement. When the user wishes to use the earphone, the user presses the button 5 to utilize the flexible force of the first flexible portion 4 to expose the earphone 2. When the user does not wish to use the earphone 2, the earphone 2 is received in the receiving slot 13. The problem of the earphone being broken due to the impacts of external forces is avoided. When the user is not using the Bluetooth earphone, the user can place the wireless earphone arbitrarily. It prevents the Bluetooth earphone from being damaged, and makes it convenient for the user to carry around.
