## Abstract

The present application discloses a speaker earphone. Each earphone unit includes a first speaker group and/or a second speaker group. The first speaker group includes a first speaker, a second speaker, and at least one capacitor. The second speaker group includes a first speaker, a second speaker, a third speaker, and at least one capacitor. In the present disclosure, at least two speakers are arranged on an enclosure of the earphone. The two speakers are in reverse connection according to polarity in order to achieve a better sound effect.

## Claims

### Claim 1

A speaker earphone, comprising at least one earphone unit, each earphone unit comprises a first speaker group or a second speaker group, the first speaker group comprising a first speaker, a second speaker, and at least one capacitor connected between the first speaker and the second speaker, and the second speaker group comprising a first speaker, a second speaker, a third speaker, and at least one capacitor;
in the first speaker group, the first speaker and the second speaker are connected in series to form a series branch, or the first speaker and the second speaker are in reverse-parallel connection to form a parallel branch; one end of the series branch is connected to one end of an output signal, another end of the output signal is connected between the first speaker and the second speaker, another end of the series branch is connected to the one end of the output signal; or the parallel branch is connected to both ends of the output signal, and the capacitor is connected between a positive pole of the first speaker and a negative pole of the second speaker in the parallel branch;
in the second speaker group, the first speaker, the second speaker, and the third speaker are sequentially connected in series to form a series branch, or the first speaker, the second speaker, and the third speaker are sequentially connected in reverse-parallel pairs to form a parallel branch; one end of the series branch is connected to one end of the output signal, another end of the output signal is connected to a negative pole of the first speaker, and connected to a positive pole of the second speaker through the capacitor, another end of the series branch is connected to the one end of the output signal; or the parallel branch is connected to both ends of the output signal, and the capacitor is connected between a positive pole of the first speaker and a negative pole of the second speaker.

### Claim 2 (depends on 1)

The speaker earphone according to claim 1, wherein the number of the earphone unit is one.

### Claim 3 (depends on 1)

The speaker earphone according to claim 1, wherein, in the first speaker group, when the first speaker and the second speaker form the series branch, a sound playing direction of the first speaker and a sound playing direction of the second speaker are the same.

### Claim 4 (depends on 1)

The speaker earphone according to claim 1, wherein, in the first speaker group, when the first speaker and the second speaker are inversely connected to form the parallel branch, a sound playing direction of the first speaker and a sound playing direction of the second speaker are the same orientation or opposite orientation.

### Claim 5 (depends on 3)

The speaker earphone according to claim 3, wherein, in the first speaker group, when the first speaker and the second speaker are inversely connected to form the parallel branch, the sound playing direction of the first speaker and the sound playing direction of the second speaker are the same orientation or opposite orientation.

### Claim 6 (depends on 1)

The speaker earphone according to claim 1, wherein, in the second speaker group, when the first speaker, the second speaker and the third speaker are sequentially connected in series to form the series branch, a sound playing direction of the first speaker, a sound playing direction of the second speaker, and a sound playing direction of the third speaker are all the same.

### Claim 7 (depends on 1)

The speaker earphone according to claim 1, wherein, in the second speaker group, when the first speaker, the second speaker and the third speaker are sequentially connected in reverse-parallel pairs to form the parallel branch, a sound playing direction of the first speaker, a sound playing direction of the second speaker, and a sound playing direction of the third speaker are all the same orientation or opposite orientation.

### Claim 8 (depends on 6)

The speaker earphone according to claim 6, wherein, in the second speaker group, when the first speaker, the second speaker and the third speaker are sequentially connected in reverse-parallel pairs to form the parallel branch, the sound playing direction of the first speaker, the sound playing direction of the second speaker, and the sound playing direction of the third speaker are all the same orientation or opposite orientation.
