Description

CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of Taiwan's Patent Application No. 111149558, filed on Dec. 22, 2022, at Taiwan's Intellectual Property Office, the disclosures of which are incorporated herein in their entirety by reference.

TECHNICAL FIELD

The present disclosure is related to a somatosensory vibrator for a wearable device, and more particularly to a somatosensory vibrator for a wearable device regarding the acoustic sound.

BACKGROUND

In recent years, electronic equipment has become an important factor in people's lives. People like to engage with audio and video in an immersive way. Therefore, the resolution of electronic devices for displaying images is constantly being improved, and the acoustic sound quality of electronic devices is becoming more and more realistic.

In the equipment used for electronic game, a vibration function for the joystick that increases the sense of presence has been introduced. For example, when operating the joystick to play the game, if encountering obstacles, being hit, or encountering explosions, etc., the joystick will vibrate to simulate the real feeling that the body is experiencing. However, the components that make the joystick vibrate are all motors. The motor uses its rotation to indirectly generate vibrations. This kind of vibration does not feel strong enough on the human body. Also, earphones are commonly used in the audio electronic equipment of the e-game competition. If you want to play e-games while listening to the sound and feeling the vibration of the sound at the same time, you need an electronic device with sounds and intense vibrations.

SUMMARY OF INVENTION

In view of the above-mentioned drawbacks in the prior art, the present invention proposes a somatosensory vibrator for a wearable device, which is configured with a speaker unit rather than an electrical motor. In one embodiment, the speaker unit has a diaphragm, a coil or a voice coil that is powered to form an electromagnet, and permanent magnets, etc. After the coil is energized, it can generate suction or thrust on the diaphragm with the permanent magnet, causing the diaphragm to vibrate vertically so that when the wearable device is attached to the user, the vertical vibration of the somatosensory vibrator can make the user feel a strong sense of presence of vibration. The speaker unit is electrically connected to the communication device. The communication device includes a transceiver, a decoder, and a low-pass filter, and can receive the wireless signal with sound from the mobile device. The wireless signal is then converted into an analog signal by the decoder, and the analog signal can be outputted to the earphone and low-pass filter at the same time. After the analog signal passes through the low-pass filter, the low-pass filter outputs a low-frequency sound signal to drive the speaker unit to vibrate.

In one embodiment, the speaker unit is completely disposed in a casing, and is completely covered by the casing. For example, the diaphragm of the speaker unit is not exposed outside. In another embodiment, the speaker unit is partly disposed in a casing. For example, the diaphragm of the speaker unit is exposed outside, but other parts of the speaker unit, such as coils or voice coils, permanent magnets, etc., are disposed in the casing.
