The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0029] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0031] Example 1

[0032] See also Figure 2 and Figure 4A Bluetooth communication headset includes a contact piece A40 and a contact piece B50 which are integrally formed on the back of a Bluetooth headset body 10 and can trigger an electrical signal. The contact piece A40 and the contact piece B50 are respectively connected to a single-chip microcomputer 60 inside the Bluetooth headset body 10. When the contact piece A40 and the contact piece B50 are touched by a finger, an electrical signal can be generated and transmitted to the single-chip microcomputer 60.

[0033] In this embodiment, the touch sheet A40 and the touch sheet B50 can directly replace the buttons, have an unobtrusive appearance, are beautiful and easy to operate.

[0034] Example 2

[0035] Different from the first embodiment, the present embodiment proposes a specific structure of the contact sheet A40 and the contact sheet B50; the contact sheet A40 and the contact sheet B50 are respectively provided with an embedded negative contact 41 and a positive contact 42 capable of conducting electricity. When the negative contact 41 and the positive contact 42 are turned on by a finger, they can form a loop with the signal acquisition module 62 on the single-chip computer 60. In implementation, the signal acquisition module 62 is set as a current acquisition circuit (such as Figure 4 (x, y in ).

[0036] In this embodiment, since human fingers can conduct electricity, when the fingers touch, a conducting circuit can be directly formed to generate a current signal, which has a simple structure, low cost and easy operation.

[0037] At the same time, the generated current signal is not directly controlled, but collected through the signal acquisition module 62. Since the single-chip computer 60 has a timer, it can collect signals within a time period to form a signal group, thereby forming a command; in this way, a variety of command operations can be achieved using only two contacts.

[0038] In the following example, first touch the contact A40 once, recorded as [A].

[0039] Touch the contact piece B50 once, recorded as [B];

[0040] As mentioned above, 1.2 seconds is set as an operation timing period. Then the commands completed within 1.2 seconds are:

[0041] [A], command: sound +3;

[0042] [B], the command is: sound -3;

[0043] [AA], command: answer / hang up;

[0044]

BB

[0045] [AB], the command is: next song;

[0046]

BA

[0047] For example, other command groups include: [AAB], [ABB], [BAA], [BBA], [AABB], and [BBAA]; the commands may include: start navigation, wake up voice, call, and other commonly used commands; the above combination of commands is the best, as too many commands will be inconvenient for users to remember; practice makes perfect, and users will be able to use these commands proficiently as they use them more.

[0048] Example 3

[0049] Different from the second embodiment, a charging circuit 63 connected in parallel with the signal acquisition module 62 is connected between the negative contact 41 and the positive contact 42 on the contact piece B50 , and the charging circuit 63 is connected to the battery 70 in the Bluetooth headset body 10 .

[0050] In this embodiment, the charging circuit 63 can be used directly to allow the contact piece B50 to serve as a charging port for charging. The Bluetooth headset is placed in the headset box, and the charging head in the headset box is connected to the negative contact 41 and the positive contact 42 on the contact piece B50 to achieve charging. This reduces the number of charging ports and is very convenient.

[0051] Example 4

[0052] Different from the third embodiment, a switch circuit 61 (such as Figure 4 c, d, e).

[0053] In this embodiment, the signal acquisition circuit of contact piece A40, the signal acquisition circuit of contact piece B50 and the on / off of charging circuit 63 can be controlled by switching circuit 61, so that it is convenient to use in a humid or spraying environment (such as taking a shower) and no false signal of circuit conduction will be generated due to water.

[0054] Example 5

[0055] Different from the second embodiment, a plurality of negative contacts 41 and a plurality of positive contacts 42 are provided, the plurality of negative contacts 41 are interconnected and share a negative connection line, and the plurality of positive contacts 42 are interconnected and share a positive connection line.

[0056] In this embodiment, since the user's fingers are of different sizes and shapes, the negative contact 41 and the positive contact 42 may not be touched at the same time in the point-touch mode, resulting in inconvenience in operation; for this reason, multiple negative contacts 41 and positive contacts 42 are provided to increase the success rate.

[0057] Example 6

[0058] Different from Example 4, Figure 1As shown in FIG. 1 , a button 20 connected to the single-chip microcomputer 60 is installed at the lower end of the Bluetooth headset body 10 , and a sound pickup hole 21 of the Bluetooth headset body 10 is opened on the button 20 .

[0059] First, the button 20 is used to input signals and turn the machine on and off; a long press turns the machine on or off; a single press closes the switch circuit 61 or opens the switch circuit 61; and the sound pickup hole 21 is arranged on the button 20, so it is easy to block it with your hand. Usually, when in use, the thumb of the right hand blocks the sound pickup hole 21, and the index finger and middle finger of the right hand can be on the contact piece A40 and the contact piece B50 respectively, which is convenient for operation.

[0060] Example 7

[0061] Different from Example 6, the button 20 is configured as a waterproof button (rubber waterproof button), and the sound pickup hole 21, the pressure relief hole, and the sound outlet hole 30 of the Bluetooth headset body 10 are all provided with a waterproof membrane (Micros waterproof membrane).

[0062] In this embodiment, when the switch circuit 61 can be disconnected, the contact piece A40 and the contact piece B50 are rendered ineffective, and the waterproof effect is further enhanced. It can be used in bathing, which is very convenient.

[0063] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive. Although the present application is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to perform equivalent replacement of some of the technical features therein. Any equivalent structure made using the contents of the specification and drawings of this application, directly or indirectly used in other related technical fields, is similarly within the scope of patent protection of this application.
