Description

Wearable Bluetooth Speaker {WEARABLE BLUETOOTH SPEAKER}

The present invention relates to a wearable Bluetooth speaker connected to another device using Bluetooth to reproduce sound.

Bluetooth is a short-range wireless technology standard that exchanges information by connecting mobile devices such as mobile phones, laptops, earphones, and headphones. It is mainly used when a low power wireless connection is required at a very short distance of about 10 meters. For example, with a Bluetooth headset, you can listen to music from your MP3 player in your pocket without the hassle of cables.

In the past, using Bluetooth technology, a headset that can be connected to a mobile phone via Bluetooth without using a hand while driving has been used.

On the other hand, as smartphones and tablet PCs have become popular, it is possible to enjoy movies or music using smartphones and tablet PCs regardless of the place. However, due to the limitations of the microspeakers built into smartphones and tablet PCs, it was impossible to reproduce high quality sound. To compensate for this drawback, a Bluetooth speaker connected to a smartphone or tablet PC via Bluetooth may be used.

Such a Bluetooth speaker is being developed in a wearable form to maximize portability. The wearable Bluetooth speaker is often paired with a smartphone to provide a hands-free function. At this time, howling was often generated in the wearable Bluetooth speaker, and improvement was necessary.

Republic of Korea Patent Publication 10-2014-0064590 Republic of Korea Patent Registration 10-1289244

An object of the present invention is to provide a wearable Bluetooth speaker that is excellent in portability as a wearable speaker and can reduce howling during hands-free calls.

The present invention

Wearable Bluetooth speaker provided by the present invention has the advantage that the howling can be reduced during hands-free calls by adjusting the installation position of the microphone and the speaker, or by controlling the speaker located near the microphone not to operate during the call.

2 is a view schematically showing a user wearing a wearable Bluetooth speaker according to a second embodiment of the present invention;
3 is a view schematically showing a user wearing a wearable Bluetooth speaker according to a third embodiment of the present invention;
4 is a diagram illustrating a wearable Bluetooth speaker according to a fourth embodiment of the present invention.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 is a perspective view of a wearable Bluetooth speaker according to a first embodiment of the present invention.

Wearable Bluetooth speaker 100 according to the first embodiment of the present invention is a neck band type that the user can wear on the neck, is installed in the neck band-type frame 110, the frame 110, and reproduces two or more different sound ranges It includes a plurality of speakers (212, 214, 216, 222, 224, 226), Bluetooth module, and includes a control unit (not shown) for controlling the plurality of speakers (210, 220, 230) according to the Bluetooth signal.

The wearable Bluetooth speaker according to the first embodiment is a two-channel speaker in which a plurality of speakers 212, 214, 216, 222, 224, and 226 are disposed at opposite ends of the wearable frame, and the speakers 212 disposed in each channel. , 214, 216, 222, 224 and 226 are provided in pairs at opposite positions. When the user wears the wearable Bluetooth speaker, the tweeter speakers 212 and 222, the mid-range speakers 224 and 224, and the woofer speakers 216 and 226 are sequentially arranged in both channels from positions close to the ears.

The wearable frame 110 has an installation space for components other than the speakers 212, 214, 216, 222, 224, 226 at both ends where the plurality of speakers 212, 214, 216, 222, 224, 226 are mounted. A portion except for both ends is provided in a thin band form to improve wearability.

The microphone 300 is installed on the wearable frame 110 for hands-free communication, and is installed at either end of both ends.

The wearable Bluetooth speaker according to the first embodiment of the present invention does not operate the speakers 222, 224, and 226 of a channel installed at an end where the microphone 300 is located in order to reduce howling during a call, and the microphone 300 does not operate. Howling can be minimized by actuating only the speakers 212, 214, 216 of the channel opposite the position.

Alternatively, in another method of minimizing howling of the wearable Bluetooth speaker according to the first embodiment of the present invention, the tweeter speakers 212 and 222 and the midrange speakers 214 and 224 of both channels are turned off during a call, and the woofer speaker By operating only 216 and 226, the howling can be minimized. This method focuses on the high-frequency signal in terms of noise.

The first embodiment shown in FIG. 1 is a neckband type Bluetooth speaker as an example, but is not limited to the neckband type, wearable form that can be worn by the user's body, such as necklace type, wrist band type, earring type, etc. It can be applied in any form.

2 is a diagram schematically illustrating a configuration of a woofer speaker included in a wearable Bluetooth speaker according to a second embodiment of the present invention.

The wearable Bluetooth speaker according to the second embodiment of the present invention has the same configuration as that of the first embodiment, but the position of the speaker and the microphone in the frame is somewhat different from that of the first embodiment.

Wearable Bluetooth speaker according to a second embodiment of the present invention, when the user wears the distance between the microphone 300 (see Fig. 1) and the mouth (M) and the speaker (212, 214, 216, 222, 224, 226) It is characterized in that it is further than the distance of the ear (E). In this case, all the speakers 212, 214, 216, 222, 224, 226 may be operated in the call mode, but only the speakers 212, 222 close to the ears E (see FIG. 1) may be operated so that the microphone ( The noise introduced into 300 may be minimized. In addition, the distance between the microphone and the mouth M is closer to the distance between the microphone 300 and the speakers 212, 214, 216, 222, 224, 226, so that the speakers 212, 214, 216, 222, 224, 226 It is desirable to be able to convey the user's voice better than the sound.

3 is a diagram schematically illustrating a user wearing a wearable Bluetooth speaker according to a third embodiment of the present invention.

The wearable Bluetooth speaker according to the third embodiment of the present invention has the same shape and arrangement as that of the first embodiment but differs in that two microphones 310 and 320 are installed. The wearable Bluetooth speaker 100 ′ according to the third embodiment of the present invention is provided with microphones 310 and 320 at both left and right sides thereof. The control unit selects only the one having the larger signal (310 in FIG. 3) to be used as the input signal. In addition, the speaker channel located at the same side as the microphone 310 having the larger signal is not operated. Accordingly, howling can be reduced by operating only the speaker channel opposite the microphone 310 used as the input signal.

4 is a diagram illustrating a wearable Bluetooth speaker according to a fourth embodiment of the present invention. In the wearable Bluetooth speaker 100 ″ according to the fourth embodiment of the present invention, a speaker to be used at the back of the neck, that is, at the back of the neck, is disposed on the basis of a shoulder point of the user when the user wears the speaker. The speaker used during the call may be one of the tweeter speakers 212 and 214, the midrange 214 and 224, or the woofer speakers 216 and 226, or may be a separately added call speaker. By providing a separate bone conduction unit (not shown), howling can be reduced by allowing a voice signal to be transmitted through the bone conduction unit (not shown) during a call.

The microphone used in the first to fourth embodiments can make the voice better by forming a dish-shaped recess around the microphone in the frame. In addition, by directing the dish shape toward the user's mouth, it is possible to provide a clearer call quality by better catching the voice signal from the user's mouth than the sound from the speaker.
