Description

Three-dimensional extended contact microphone device

technical field

The present invention relates to a microphone device, in particular to a contact microphone device with a three-dimensional structure.

Background technique

Microphone devices are common devices in people's daily life. Especially in recent years, with the popularity of consumer mobile electronic devices such as mobile phones and PDAs, various novel microphone devices, such as ear-hook microphone devices combined with earphones, wireless microphone devices combined with Bluetooth, etc. Get the attention of the market.

Traditional microphone devices mostly use capacitive sound collection, which mainly uses air as the medium to collect the sound from the sound source. However, since the noise of the surrounding environment will also be collected by the condenser microphone device through the air along with the sound of the sound source, the condenser microphone device is not suitable for use in a noisy environment. In order to solve the aforementioned shortcomings of the condenser microphone device, another known contact microphone device is attached to the lower jaw of the speaker, and is piezoelectrically (piezoelectric) by sensing the skin vibration of the throat resonance when the speaker speaks. converted into electrical signals.

Figure 1a is a perspective view of a conventional contact microphone device. As shown in the figure, the known contact microphone device is a planar annular body 10 similar to the letter "C". ) to the signal line 12 connected. Some microphone devices are also connected with one or two earphone elements (for use with one ear or both ears), but for the sake of simplification, they are not shown in the figure. The annular body 10 of the microphone device has the elasticity of planar outward expansion and inward clamping, so when wearing it, the annular body 10 is opened slightly outward to surround the user's neck, and the result is shown in Figure 1b situation.

The most suitable position for the contact type microphone device is the position shown by the dotted line (a) in FIG. 1b. In this position, the sound-receiving element 11 is attached to the upper edge of the neck adjacent to the lower jaw, so as to induce the maximum laryngeal cavity resonance. However, because the inward clamping elasticity of the annular body 10 of the contact microphone device is not too strong so as not to cause discomfort to the user, in actual use, due to the user's actions, the rotation of the neck, etc., the contact microphone device often loses The lower edge of the neck slides to the position shown by the dotted line (b) in FIG. 1b, and the sound-receiving element 11 will not be close to the skin, both of which make the sound-receiving effect of the contact microphone device 10 greatly reduced.

Contents of the invention

Therefore, the present invention proposes a contact microphone device with an improved structure to address the structural shortcomings of the conventional contact microphone device.

The microphone device of the present invention at least includes a plastic and elastic linear element, and a sound-receiving element arranged at one end of the linear element. The linear element stretches to form a three-dimensional structure; in the top view, the linear element forms a ring shape similar to the letter "C", and in the side view, the two ends of the linear element bend upward and downward at an appropriate angle, And form a shape similar to the symbol "<". With the three-dimensional structure of the linear element, the linear element of the microphone device can surround the user's neck, one end of which is supported by the skin near the clavicle at the bottom of the user's neck, so that the other end with the sound-absorbing element can be attached stably The upper edge of the user's neck is close to the lower jaw, so that excellent sound-receiving effects can be obtained, and the sound-receiving element will not deviate from its best position due to the user's actions and neck rotation.

The contact microphone structure proposed by the present invention is not only suitable for connecting with other electronic devices in a wired manner, but also suitable for connecting with electronic devices in a wireless transmission mode such as Bluetooth. For the latter, the bluetooth transceiver element is arranged at an appropriate position on the linear element, and the wire between the bluetooth transceiver element and the radio element can be hidden in the linear element.

Detailed ways

2a, 2b, and 2c respectively show a top view, a side view, and a perspective view of a microphone device according to a first embodiment of the present invention. As shown in the figure, the microphone device of this embodiment includes a linear element 20 , a sound receiving element 21 disposed at one end of the linear element 20 , and a signal line 22 extending from the other end of the linear element 20 . The sound-receiving element 21 receives the skin vibration when a user makes a sound in a skin-to-skin contact manner and converts it into an electrical signal. The sound-receiving element 21 is usually a piezoelectric microphone, but the present invention does not specifically limit the sound-receiving mode and adopted technology of the sound-receiving element 21 . One end of the signal line 22 has a suitable plug to connect with the microphone input connector of other devices. Likewise, the present invention does not particularly limit the position where the signal wire 22 extends from the linear element 20 , and the form and type of the plug.

The linear element 20 extends to form a three-dimensional structure. In the top view as shown in FIG. 2 a , the linear element 20 is in the shape of a letter "C". The diameter of the ring is approximately the same as the width of an average person's neck. The linear element 20 has proper elasticity to open and close outwards, so the user can pull the annular opening of the linear element 20 to the left and right, and then put the linear element 20 on the neck from the back of the neck forward. The elasticity of the linear element 20 restores its annular opening to its original size. Under the side view angle shown in Figure 2b, one end of the linear element 20 provided with the sound receiving element 21 is bent upward at an appropriate angle (theta angle shown in the figure), and the other end of the signal line 22 is extended Then bend downward at an appropriate angle (the angle  shown in the figure) to form a shape similar to the symbol "<".

The linear element 20 has proper plasticity to maintain the above-mentioned three-dimensional structure. Also because of this plasticity, if necessary, the user can adjust the angle of bending up and down of the linear element 20 (that is, angle θ, angle ), and the size of the annular opening, so that the linear element 20 can be worn more comfortably and fit better. The specific shape of the user's neck. There are many ways to implement the linear element 20 . For example, the linear element 20 is composed of a metal wire body wrapped in a gel envelope. In addition, although not shown in the figure, there is usually a two-core wire connected between the sound receiving element 21 and the signal wire 22, and this wire can be wrapped together and hidden in the rubber envelope of the linear element 20, In order to transmit the electric signal of the sound receiving element 21 to the signal line 22 .

Fig. 2d is a schematic diagram of wearing the microphone device of Fig. 2a. As shown in the figure, the linear element 20 surrounds the user's neck, and one end extending from the signal line 22 is supported by the skin near the clavicle at the bottom of the user's neck, so that the other end with the sound-receiving element 21 can be attached stably. At the position where the upper edge of the user's neck is adjacent to the lower jaw, the sound-receiving element 21 will not deviate from its optimum sound-receiving position due to the user's actions and neck rotation.

Fig. 2e shows another embodiment of the three-dimensional structure of the microphone device in Fig. 2a. As shown in the figure, in this embodiment, the linear element 20 is still in the shape of a letter "C" in the top view as shown in FIG. 2a. However, under the side view angle shown in Figure 2e, the end of the linear element 20 provided with the acoustic element 21 is bent upwards at an appropriate angle (angle θ as shown in the figure), and it is further above the upward direction of the linear element 20. The appropriate position of the extension section turns upward again at an appropriate angle (as shown in the figure, it is close to vertical upward, but not limited to this), and the other end of the signal line 22 is still bent at an appropriate angle (as shown in the figure)  angle shown in ) downward. In this way, this embodiment is not only more suitable for users with long necks, but also allows for more accurate positioning of the sound-receiving element 21 .

3a and 3b show perspective views of microphone devices according to second and third embodiments of the present invention, respectively. These two embodiments are the same as the previous embodiment, the only difference is that the earphones 30 , 31 for one ear or two ears extend outward from the appropriate position of the sound receiving element 21 or the linear element 20 . Similarly, the present invention does not particularly limit the position, form and type of the earphones 30 , 31 extending outward from the linear element 20 . The earphones 30 , 31 and the signal line 22 are also connected by a wire (not shown) for signal transmission, and the wire can also be hidden in the linear element 20 .

In addition to the aforementioned wired microphone devices, the present invention is also applicable to wireless microphone devices. Fig. 4a shows a perspective view of a microphone device according to a fourth embodiment of the present invention. As shown in the figure, the wireless transmission transceiver element 40 is disposed at the other end of the sound receiving element 21 . The wireless transmission transceiver component 40 may support bluetooth or other suitable wireless transmission protocols. The present invention does not specifically limit the specifications and technologies of wireless transmission. The wires between the wireless transmission transceiver element 40 and the sound receiving element 21 can be hidden in the linear element 20 as in the wired embodiment. A large number of technical details of the wireless transmission transceiver element 40 have been disclosed, so they are omitted here. The wireless transmission transceiver element 40 can actually be arranged at a proper position along the linear element 20, as shown in FIG. 4b for example.

The features and spirit of the present invention are described more clearly by the detailed description of the preferred embodiments above, rather than limiting the scope of the present invention by the preferred embodiments disclosed above. On the contrary, the intention is to cover various changes and equivalent arrangements within the scope of the claimed patent scope of the present invention.
