Description

Underwater speaker resonance device

The present invention provides an underwater speaker resonance device, and in particular, an underwater speaker resonance device that can play music in the water, share music with surrounding friends who are also in the water, and can be controlled over short distances in a wired or wireless manner.

Press, the speed of sound is also called the speed of sound, which is the speed of sound. It is defined as the distance traveled by vibration waves per unit time. Its transmission rate has an absolute relationship with the material of the transmission medium. For example, the speed in air is 340m/s, in fresh water The speed in water is 1410m/s and in sea water is 1510m/s. However, electromagnetic waves will be greatly attenuated when transmitted in water. The shorter the wavelength, the greater the attenuation. Therefore, even if Bluetooth speakers are very popular, even if Bluetooth speakers have With the waterproof function, no one will play it in the water, because once the speaker enters the water, whether it is the control signal or the sound signal before decoding, the Bluetooth signal from the mobile phone will be absorbed in the water.

Swimming or diving is a kind of exercise that can increase lung capacity and can also exercise the muscles of the whole body. It is of great help to health care. However, generally speaking, music cannot be played while swimming or diving, so during long-term exercise, It is inevitable to feel depressed. Currently, the devices known as underwater speakers or underwater speakers are commonly used in the following ways: 1. Use high-end waterproof equipment and headphones to allow users to listen to music in the water; 2. Combine with bone conduction technology to stream music directly from Incoming from behind the ear bone also allows users to listen to music in the water; third, sacrifice long-distance transmission or some control functions and simply play music through a small speaker that can be carried around.

However, when using the above-mentioned underwater speakers or underwater speakers, there are the following problems and deficiencies that need to be improved: 1. The music can only be listened to by the wearer and cannot be shared with friends in the water; 2. It cannot be controlled remotely and only Can simply play music.

Therefore, how to solve the above conventional problems and deficiencies is the direction that the inventor of the present invention and related manufacturers engaged in this industry are eager to research and improve.

Therefore, in view of the above shortcomings, the inventor of the present invention collected relevant information, evaluated and considered many aspects, and used his many years of experience in this industry, and through continuous trials and modifications, he designed this kind of device that can play music in the water. , the inventor and patentee of an underwater speaker resonance device that can share music with friends who are also underwater and can be controlled over short distances via wired or wireless methods.

The main purpose of the present invention is to arrange the sound-generating device in the cavity of the underwater equipment to provide a resonance environment for the sound-generating device, thereby transmitting the music and sharing it with friends around who are also in the water.

Another main object of the present invention is that the control device of the sound-generating device can be installed outside the underwater equipment, and the wired or wireless control signals of the signal transmission device can be transmitted inside the hollow tube or in the water.

In order to achieve the above object, the main structure of the present invention includes: an underwater equipment, a cavity with gas inside, a hollow tube body, a sound device, a control device, and a signal transmission device, wherein the cavity is Formed in underwater equipment, the hollow pipe system is provided on one side of the underwater equipment and communicates with the cavity, and the sound-generating device is provided in the cavity to use the gas in the cavity to resonate and sound to play music, The control device is installed outside the underwater equipment, and is operated by the user to generate a control signal to control the sound-generating device, and the signal transmission device is an information link between the sound-generating device and the control device, so that the control signal is transmitted in the Pass in empty tubes or in water.

The invention sets the sound-generating device in the cavity of the underwater equipment to use the gas in the cavity to resonate and produce sound. Therefore, it can not only produce music in the water, but also transmit the music to surrounding friends who are also in the water. And the control device is set up separately from the sound-generating device, and the signal transmission device is used in a wired or wireless manner to transmit the control signal to the sound-generating device through the waterless environment in the hollow tube body, or sonar is used to control the waterway to transmit the control signal. In this way, it not only has the advantage of convenient operation because the control device can be set freely, but also because the control signal can be transmitted normally, allowing the user to normally operate the existing functions of the sound-generating device.

Through the above technology, we can solve the problems of conventional underwater speakers or underwater speakers, such as the music can only be listened to by the wearer, the music cannot be shared with friends in the water, cannot be controlled remotely, and can only simply play music. Make breakthroughs to achieve the practical progress of the above advantages.
