Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. In addition, the technical features in each embodiment or a single embodiment provided by the present invention can be combined with each other arbitrarily to form a feasible technical solution. This combination is not restricted by the order of steps and / or the pattern of structural composition, but must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] The embodiments of the present invention provide a bone conduction headset based on an energy-enhanced antenna. Refer to Figure 1 , the device includes: a sound wave generator 101, connected to an electronic device wire 102, an antenna wire 104, and a wire outer skin 103, for sending sound waves to the wearer; an electronic device wire 102, connected to an internal circuit board 106, for connecting the sound wave generator 101 and the electronic components on the internal circuit board 106; an antenna wire 104, connected to an energy-enhanced antenna assembly 105, for connecting the sound wave generator 101 and the energy-enhanced antenna assembly 105; a wire outer skin 103, wrapped around the electronic device wire 102 and the antenna wire 104, for protecting the electronic device wire 102 and the antenna wire 104; an energy-enhanced antenna assembly 105, connected to the antenna wire 104, suspended above the internal circuit board 106, for receiving and transmitting radio waves and enhancing the energy of the received and transmitted radio waves; an internal circuit board 106, disposed in a controller housing 107, for integrating electronic components.

[0023] Refer to Figure 2, based on the above embodiments, the bone conduction headset with an energy-enhanced antenna provided in the embodiments of the present invention, the energy-enhanced antenna assembly includes: an antenna body 201, disposed on an antenna bracket 202, for receiving and transmitting radio waves and enhancing the energy of the received and transmitted radio waves; an antenna bracket 202, disposed on an internal circuit board 106, for mounting the antenna body 201 and suspending the antenna body 201 above the internal circuit board 106.

[0024] See Figure 3 , based on the above embodiments, the bone conduction headset with an energy-enhanced antenna provided in the embodiments of the present invention, the shape of the antenna body 201 is a double-headed shovel shape, and the length of the double-headed shovel shape is determined as a first preset length according to the electromagnetic wave propagation speed and the current pulse period.

[0025] Specifically, the shape of the antenna body 201 being a double-headed shovel shape has better energy transmission and reception characteristics than a traditional strip antenna, that is, the energy transmission and reception power of the antenna can be enhanced by changing the shape itself. In addition, it should be noted that such an antenna body 201 in the shape of a double-headed shovel is mainly used for receiving or transmitting energy at a short distance. For example, during the process of people talking face to face, the distance for receiving or transmitting energy in this case is usually within 1 meter to 5 meters, specifically it can be a distance of 3 meters. And during a short-distance call, setting the length of the double-headed shovel shape to the first preset length can further optimize the energy transmission and reception power of the antenna body 201 in the shape of a double-headed shovel, that is, enhance its power for receiving and transmitting energy.

[0026] See Figure 4 , based on the above embodiments, the bone conduction headset with an energy-enhanced antenna provided in the embodiments of the present invention, the shape of the antenna body is a silver ingot shape 401, and the length of the silver ingot shape 401 is determined as a second preset length according to the electromagnetic wave propagation speed and the current pulse period.

[0027] Specifically, the shape of the antenna body being a silver ingot shape 401 has better energy transmission and reception characteristics than Figure 3 the antenna body in the shape of a double-headed shovel in

[0028] Based on the above embodiments, in the bone conduction earphone based on an energy-enhanced antenna provided in the embodiments of the present invention, the first preset length includes:

[0029]

[0030] Among them, L1 is the preset length; ξ is the electromagnetic wave propagation speed; T is the current pulse period; b is the distance of the radio wave transmitted and received.

[0031] Continue to refer to Figure 3 , during a call at a short distance (the specific concept is as defined above), there is still a surplus in the waveform of the electromagnetic wave energy transmitted and received at the previous moment (that is, there is still energy residue). Experiments show that if the length of the antenna body 201 of the double-headed shovel shape is set as shown in formula (1), the waveform extreme value of the electromagnetic wave energy transmitted and received at the current moment can be superimposed with the waveform extreme value of the energy residue of the electromagnetic wave energy transmitted and received at the previous moment, so as to further enhance the field strength of the transmitted and received energy through superposition, that is, the power of the transmitted and received energy is increased.

[0032] Based on the above embodiments, in the bone conduction earphone based on an energy-enhanced antenna provided in the embodiments of the present invention, the second preset length includes:

[0033] L2 = 2ξT (2)

[0034] Among them, L2 is the second preset length.

[0035] Continue to refer to Figure 4 , during a call at a long distance (the specific concept is as defined above), although the energy situation is similar to that of a short-distance call, that is, there is still a surplus in the waveform of the electromagnetic wave energy transmitted and received at the previous moment (that is, there is still energy residue). Experiments show that if the length of the antenna body of the silver ingot shape 401 is set as shown in formula (2), the waveform extreme value of the electromagnetic wave energy transmitted and received at the current moment can be superimposed with the waveform extreme value of the energy residue of the electromagnetic wave energy transmitted and received at the previous moment, so as to further enhance the field strength of the transmitted and received energy through superposition, that is, the power of the transmitted and received energy is increased. Thus, Figure 3 the antenna body 201 of the double-headed shovel shape in Figure 4 and the antenna body of the silver ingot shape 401 in

[0036] Both can play a role in enhancing the power of radio wave energy transmission and reception. The difference between the two is only limited to different application scenarios (that is, the distance of the call), and by setting different antenna body lengths in different application scenarios, the effect of enhancing the power of radio wave transmission and reception energy can be achieved. Figure 2, based on the above embodiments, the bone conduction headset with an energy-enhanced antenna provided in the embodiments of the present invention, the internal circuit board 106 further includes: a circuit switch 203 for turning on or off the internal circuit board 106; a grounding device 204 for grounding the internal circuit board 106; a capacitor bank 205 for voltage reduction and energy storage; and a controller 206 for processing input signals and outputting control signals.

[0037] The bone conduction headset with an energy-enhanced antenna provided by the present invention can increase the energy transceiver efficiency of radio waves within the limited space of the bone conduction headset by performing an energy enhancement design on the antenna and improving the shape and length of the antenna, thereby improving the signal transmission quality of the bone conduction headset.
